Resumen
This paper introduces a fuzzy logic-based autonomous ship deck landing system for fixed-wing unmanned aerial vehicles (UAVs). The ship is assumed to maintain a constant course and speed. The aim of this fuzzy logic landing model is to simplify the task of landing UAVs on moving ships in challenging maritime conditions, relieving operators from this demanding task. The designed UAV ship deck landing model is based on a fuzzy logic system (FLS), which comprises three interconnected subsystems (speed, lateral motion, and altitude components). Each subsystem consists of three inputs and one output incorporating various fuzzy rules to account for external factors during ship deck landings. Specifically, the FLS receives five inputs: the range from the deck, the relative wind direction and speed, the airspeed, and the UAV’s flight altitude. The FLS outputs provide data on the speed of the UAV relative to the ship’s velocity, the bank angle (BA), and the angle of descent (AOD) of the UAV. The performance of the designed intelligent ship deck landing system was evaluated using the standard configuration of MATLAB Fuzzy Toolbox.

Resumen
This paper mainly studies the longitudinal and lateral deck motion compensation technology. In order to ensure the safe landing of the carrier-based aircrafts on the flight decks of carriers during the landing process, it is necessary to introduce deck motion information into the guidance law information of the automatic landing guidance system when the aircraft is about to land so that the aircraft can track the deck motion. To compensate the influence of the height change in the ideal landing point on the landing process, the compensation effects of the deck motion compensators with different design parameters are verified by simulation. For further phase-lead compensation for the longitudinal automatic landing guidance system, a deck motion predictor is designed based on the particle filter optimal prediction theory and the AR model time series analysis method. Because the influence of up and down motions on the vertical motion of the ideal landing point is the largest, the compensation effects of the designed predictor and compensator are simulated and verified based on the up and down motion of the power spectrum. For the compensation for the lateral motion, a tracking strategy of the horizontal measurement axis of the inertial stability coordinate system to the horizontal axis of the hull coordinate system (center line of the deck) is proposed. The tracking effects of the horizontal measurement axis of the designed integral and inertial tracking strategies are simulated and compared. Secondly, the lateral deck motion compensation commands are designed, and the compensation effects of different forms of compensation commands are verified by simulations. Finally, the compensation effects for the lateral deck motion under integral and inertial tracking strategies are simulated and analyzed.

Resumen
The disturbances in the landing process of carrier-based aircraft include deck movement and ship wake. To guarantee the security of landing process, the simulation and model are necessary for the disturbances, and the deck movement and ship wake should be analyzed as well. On the basis of analysis of disturbances, the disturbances can be catalogued into two types: deck movement and ship wake. Combining with the relevant instructions in the American Army Standard, the mathematical model of each disturbance is established. The simulations of the deck movement and ship wake are also shown in this paper, which can supply the reliable disturbances models for the design of the control system of carrier-aircraft landing process.

Resumen
Abstract Carrier aircraft landing is a system engineering with strong nonlinear, strong coupling, and complex environmental interference. Landing control is one of the key technologies for carrier aircraft landing, which directly affects the success of the landing. A longitudinal decoupling control method based on Model Compensated Linear Active Disturbance Rejection Control (MCC-LADRC) is proposed for tracking the deck motion and maintaining the attack angle in the final stage of the carrier landing. The simulation results show that compared with the PID control and traditional LADRC strategy, the MCC-LADRC method can not only control the carrier aircraft to track the deck motion synchronously and accurately, improve the landing accuracy and anti-disturbance capability but also has a good attack angle retention effect and eliminate the coupling between the pitch angle and the attack angle.

Resumen
In order to investigate the influence of ship airwake on aerodynamic characteristics of the carrier-based aircraft, UAV's landings in different winds over deck were simulated by Overset Mesh method. Firstly, mesh factors, steady and unsteady methods were compared based on single aircraft carrier. The results showed that the boundary layer mesh around ship didn't show obvious influence for our simulation, and the calculation results between the steady and unsteady time average showed a similar trend. Then, aircraft carrier's flow fields in three wind directions were analyzed, and ship airwake variations with different direction winds over deck were concluded as well. Next, the reliability of Overset Mesh was verified though single UAV's landing simulation. Finally, the coupled flow fields of UAV/ship were studied. The calculation results indicated that aircraft was always in a low dynamic pressure condition, the lift and pitching moment of UAV had apparent changes in landing. Meanwhile, the aerodynamic fluctuations of UAV also revealed differences in different wind directions. The simulation results can be regarded as a reference for the safety assessment of carrier-based aircraft's landing and its control in the future.

Resumen
For large warships, aircrafts play an important role in the war. So during the development of large warships, the safety of the aircrafts takeoff and landing becomes the key technology, which requires the air-wake around large warship decks provide a safety environment for its busy work. However, for the warships with flush deck, superstructure is the main reason of causing air turbulence on the ship surface. At the same time, the states of motion also have an effect on air-wake such as pitch, rolling, etc. It will lead to air crash or inability of takeoff and landing if the air-wake around decks cannot meet the work requirements of the aircrafts. Therefore, the numerical simulation of air-wake around decks is very important for the development of large warships during the war.

Resumen
The deck landing sinking velocity of carrier-based aircraft is affected by carrier attitude, sea condition, aircraft performance, etc. Its impact analysis is a complex nonlinear problem, and there even is some contradictory phenomenon that when the approach velocity increases, the sinking velocity decreases under certain circumstances. Aiming at exploring the impact of the various related deck landing parameters on sinking velocity for carrier-based aircraft in the actual environment, response surface method-based improved Kriging algorithm (IK-RSM) is proposed based on genetic algorithm and Kriging model. Based on the deck landing measured data of the F/A-18A aircraft in the actual operating environment, the impact degree of the 15 deck landing parameters on the sinking velocity is explored, respectively, by using the partial correlation analysis of multivariate statistical theory and the IK-RSM. It can be found that the 4 parameters are strongly correlated with the sinking velocity; that is, the aircraft glide angle and deck pitch angle are highly correlated with the sinking velocity; next, the approach velocity and the engaging velocity are moderately correlated with the sinking velocity. The 4 parameters above could be used to establish the impact analysis model of the sinking velocity. The genetic algorithm is applied to the correction coefficients optimization of the IK-RSM’s kernel functions, and the IK-RSM of the F/A-18A aircraft sinking velocity is formed. Compared with the Kriging model and the empirical formula, the sinking velocity prediction accuracy indexes of IK-RSM are the best; for example, the determination coefficient is 0.981, the mean relative error is 1.813%, and the maximum relative error is 6.771%. Furthermore, based on the sinking velocity IK-RSM and the sensitivity analysis method proposed, we have explained the reason for the contradictory phenomenon that when the approach velocity increases, the sinking velocity decreases at some samples. It could provide certain technical support for the flight attitude control related to the sinking velocity during the actual flight of carrier-based aircraft.

ENGLISH ABSTRACT: With a view to future ship deck landings, a moving platform landing algorithm for an unmanned autonomous helicopter was successfully designed and a number of systems were developed in order to implement the landing algorithm. Through a combination of an MCA-based ship motion prediction algorithm and the appropriate analysis of platform motion criteria, a system was developed which can identify valid landing opportunities in real ship motion data recorded at sea state 4 for up to 5 s into the future with a 75% success rate. The bandwidth of the heave motion estimator and controller of the helicopter were increased by the implementation of GPS latency compensation, and velocity and acceleration feed forward terms respectively. The resulting bandwidth of at least 0.2 Hz is sufficient to track the heave motion of a platform which is simulating the motion of a ship at sea state 4 or lower. After the various systems were integrated they were coordinated in a landing state machine. A stationary platform landing was demonstrated successfully during flight tests, verifying the functionality of the landing state machine and the integration of the system. Landings on a platform simulating the motion of a ship at sea state 4 were demonstrated successfully in hardware-in-the-loop simulations.

EMBA Project Report
EXECUTIVE SUMMARY: This project was completed by the Resource Management Solutions Group, on behalf of the Commander, Helicopter Sea Combat Wing Atlantic (CHSCWL), and facilitated through the Naval Postgraduate School Executive MBA program. The purpose is to collect and analyze data pertaining to current scheduling challenges for helicopter pilot deck landing qualifications (DLQs). The data is used to compare three potential courses of action (COAs) and provide a recommendation for a COA to pursue based on the lowest cost alternative that meets operational requirements. This study focuses on the MH-60S helicopter squadrons assigned to CHSCWL. Sortie data was gathered from the Helicopter Sea Combat Squadron Two and interview data collected from various Norfolk-based MH-60S squadrons was incorporated as well. This project focuses primarily on two areas of interest: alleviating the DLQ scheduling challenges experienced between CHSCWL and the United States Second Fleet (C2F) and finding the most cost effective solution that also meets the operational requirements of the Fleet Replacement Squadron (FRS), Fleet squadrons, and ships assigned to C2F. Our analysis examines three possible courses of action: COA 1: Continue to conduct DLQ events using the current process of utilizing fleet ships already underway for training COA 2: Dedicate a C2F duty ship with sole responsibility of conducting DLQ events for a specified period of time during its duty rotation COA 3: Award a civilian company a contract to utilize a Helicopter Landing Trainer (HLT) to conduct DLQ events in the Chesapeake Bay or James River The results show all three COAs are capable of meeting DLQ requests; however, COA 3 provides the best solution for two main reasons. A Helicopter Landing Trainer allows for the highest level of operational readiness and minimizes the scheduling difficulties that have been experienced with DLQ requirements. Additionally, using a cost comparison, COA 3 proves to be the least costly alternative. The decision to utilize an HLT would potentially yield an annual savings of nearly $1.0 million.

ENGLISH ABSTRACT: The landing phase of any helicopter is the most critical part of the whole flight envelope, particularly on a moving flight deck. The flight deck is usually located at the stern of the ship, translating to large heave motions. This thesis focuses on the three fundamental components required for a successful landing: accurate, relative state-estimation between the helicopter and the flight deck; a prediction horizon to forecast suitable landing opportunities; and excellent control to safely unite the helicopter with the flight deck. A monocular-vision sensor node was developed to provide accurate, relative position and attitude information of the flight deck. The flight deck is identified by a distinct, geometric pattern. The relative states are combined with the onboard, kinematic state-estimates of the helicopter to provide an inertial estimate of the flight deck states. Onboard motion prediction is executed to forecast a possible safe landing time which is conveyed to the landing controller. Camera pose-estimation tests and hardware-in-the-loop simulations proved the system developed in this thesis viable for flight tests. The practical flight tests confirmed the success of the monocular-vision sensor node.
AFRIKAANSE OPSOMMING: Die mees kritiese deel van die hele vlug-duurte van ’n helikopter is die landings-fase, veral op ’n bewegende vlugdek. Die vlugdek is gewoonlik geleë aan die agterstewe-kant van die skip wat groot afgee bewegings mee bring. Hierdie tesis ondersoek die drie fundamentele komponente van ’n suksesvolle landing: akkurate, relatiewe toestand-beraming tussen die helikopter en die vlugdek; ’n vooruitskatting horison om geskikte landings geleenthede te voorspel; en uitstekended beheer om die helikopter en vlugdek veilig te verenig. ’n Monokulêre-visie sensor-nodus was ontwikkel om akkurate, relatiewe-posisie en oriëntasie informasie van die vlugdek te verwerf. Die vlugdek is geidentifiseer deur ’n kenmerkende, geometriese patroon. Die relatiewe toestande word met die aan-boord kinematiese toestandafskatter van die helikopter gekombineer, om ’n beraming van die inertiale vlugdek-toestande te verskaf. Aan-boord beweging-vooruitskatting is uitgevoer om moontlike, veilige landingstyd te voorspel en word teruggevoer na die landingsbeheerder. Kamera-orientasie afskat-toetse en hardeware-in-die-lus simulasies het die ontwikkelde sisteem van hierdie tesis lewensvatbaar vir vlug-toetse bewys. Praktiese vlug-toetse het die sukses van die monokulêre-visie sensor-nodus bevestig.

ENGLISH ABSTRACT: This thesis presents a complete state estimation framework for landing an unmanned helicopter on a ship deck. In order to design and simulate an optimal state estimator, realistic sensor models are required. Selected inertial, absolute and relative sensors are modeled based on extensive data analysis. The short-listed relative sensors include monocular vision, stereo vision and laser-based sensors. A state estimation framework is developed to fuse available helicopter estimates, ship estimates and relative measurements. The estimation structure is shown to be both optimal, as it minimises variance on the estimates, and flexible, as it allows for varying degrees of ship deck instrumentation. Deck instrumentation permitted ranges from a fully instrumented deck, equipped with an inertial measurement unit and differential GPS, to a completely uninstrumented ship deck. Optimal estimates of all helicopter, relative and ship states necessary for the autonomous landing on the ship deck are provided by the estimator. Active gyro bias estimation is incorporated into the helicopter’s attitude estimator. In addition, the process and measurement noise covariance matrices are derived from sensor noise analysis, rather than conventional tuning methods. A full performance analysis of the estimator is then conducted. The optimal relative sensor combination is determined through Monte Carlo simulation. Results show that the choice of sensors is primarily dependent on the desired hover height during the ship motion prediction stage. For a low hover height, monocular vision is sufficient. For greater altitudes, a combination of monocular vision and a scanning laser beam greatly improves relative and ship state estimation. A communication link between helicopter and ship is not required for landing, but is advised for added accuracy. The estimator is implemented on a microprocessor running real-time Linux. The successful performance of the system is demonstrated through hardware-in-the-loop and actual flight testing.
AFRIKAANSE OPSOMMING: Hierdie tesis bied ’n volledige sensorfusie- en posisieskattingstruktuur om ’n onbemande helikopter op ’n skeepsdek te laat land. Die ontwerp van ’n optimale posisieskatter vereis die ontwikkeling van realistiese sensormodelle ten einde die skatter akkuraat te simuleer. Die gekose inersie-, absolute en relatiewe sensors in hierdie tesis is op grond van uitvoerige dataontleding getipeer, wat eenoogvisie-, stereovisieen lasergegronde sensors ingesluit het. ’n Innoverende raamwerk vir die skatting van relatiewe en skeepsposisie is ontwikkel om die beskikbare helikopterskattings, skeepskattings en relatiewe metings te kombineer. Die skattingstruktuur blyk optimaal te wees in die beperking van skattingsvariansie, en is terselfdertyd buigsaam aangesien dit vir wisselende mates van skeepsdekinstrumentasie voorsiening maak. Die toegelate vlakke van dekinstrumentasie wissel van ’n volledig geïnstrumenteerde dek wat met ’n inersiemetingseenheid en ’n differensiële globale posisioneringstelsel (GPS) toegerus is, tot ’n algeheel ongeïnstrumenteerde dek. Die skatter voorsien optimale skattings van alle vereiste helikopter-, relatiewe en skeepsposisies vir die doeleinde van outonome landing op die skeepsdek. Aktiewe giro-sydige skatting is by die posisieskatter van die helikopter ingesluit. Die proses- en metingsmatrikse vir geruiskovariansie in die helikopterskatter is met behulp van ’n ontleding van sensorgeruis, eerder as gebruiklike instemmingsmetodes, afgelei. ’n Volledige werkingsontleding is daarna op die skatter uitgevoer. Die optimale relatiewe sensorkombinasie vir landing op ’n skeepsdek is met Monte Carlo-simulasie bepaal. Die resultate toon dat die keuse van sensors hoofsaaklik van die gewenste sweefhanghoogte gedurende die voorspellingstadium van skeepsbeweging afhang. Vir ’n lae sweefhanghoogte is eenoogvisie-sensors voldoende. Vir hoër hoogtes het ’n kombinasie van eenoogvisie-sensors en ’n aftaslaserbundel ’n groot verbetering in relatiewe en skeepsposisieskatting teweeggebring. ’n Kommunikasieskakel tussen helikopter en skip is nie ’n vereiste vir landing nie, maar word wel aanbeveel vir ekstra akkuraatheid. Die skatter is op ’n mikroverwerker met intydse Linux in werking gestel. Die suksesvolle werking van die stelsel is deur middel van hardeware-geïntegreerde simulasie en werklike vlugtoetse aangetoon.

Resumen
Motion sensitive operations at sea are conducted in an unpredictable environment. While occasionally these operations can be planned around suitable weather forecast or delayed until smoother motions are apparent, naval ships conducting flight operations may have little liberty in their mission planning and execution. Tools exist to translate the oceanâ s harsh conditions into discretely defined low motion operational periods. Particularly of interest, the identification of discrete lull periods or quiescence for shipboard helicopter operations can be better defined using a landing period indicator than with the current method of utilizing static deck angle measurements. While few of these systems exist, assessing their operational benefits is difficult due to a lack of well-defined performance metrics.

This thesis defines and examines the use of two methodical approaches to evaluating Landing Period Indicators (LPIs) and their subject ship-helicopter dynamic interface system. First a methodology utilizing the comparison of a basic transparent algorithm is detailed and a case study employing this methodology is examined. Second, a system dynamics approach is taken to pilot workload analysis, utilizing a dynamic systems model characterizing a subset of the Dynamic Interface. This approach illustrates the realistic gains in understanding and development that can be accomplished by utilizing system dynamics in the analysis of the Dynamic Interface and LPI insertion.

Resumen
Amphibious ships, configured with floodable well decks, present a unique challenge to the Ship Design Team to incorporate maximum troop, cargo and vehicle capacity, along with sufficient well deck size, to facilitate efficient operation of LCAC (Landing Craft Air Cushion) and other amphibious assault craft in support of power projection operations. Analysis of the various LSD 49 Class alternative designs, revealed significant variance in the stability limits for each design. These variations appeared to be directly attributable to wing wall size, as well as to the geometry of the well deck. In order to better understand the effect of these items, and to develop guidelines for future design efforts, this study concentrated on evaluating the stability limitations for various combinations of beam, well deck configuration, and wing wall size using an LSD 49 Class proposed hull form. The results indicated that the most significant parameter affecting the stability of the LSD 49 Class is the height of the well deck above the baseline. The higher the well deck, the smaller the loss of waterplane inertia caused by the entrance of flooding water into the well deck compartment. For lower well decks, the loss of waterplane inertia is more critical at smaller values of beam, but becomes less critical at the upper values of beam considered. In these cases, off-center wing wall flooding becomes more critical, and it is more advantageous to devote larger percentages of beam to the well deck compartment.

Resumen
L'appontage d’hélicoptère sur un navire est une manœuvre parmi les plus difficiles pour un pilote. Les turbulences, la faible visibilité ainsi que le mouvement du pont du navire forment un environnement dégradé et engendrent une charge de travail non négligeable pour le pilote. L’automatisation complète de cette manœuvre offre à l’équipage un gain de sécurité et permet d’étendre le domaine d’utilisation des hélicoptères lors d’opérations maritimes. De plus l’émergence de drones hélicoptère d’observation conduit à développer un guidage automatique pour toutes les phases du vol et en particulier celle de l’appontage. Les études menées dans cette thèse concernent un système d’appontage automatique dont la fonction principale est d’asservir l’aéronef sur une trajectoire de rendez-vous, calculée à partir d’informations de mouvement du navire. Plusieurs stratégies de commande ont été évaluées, aussi bien dans le domaine linéaire que non linéaire. Dans un environnement sans GPS, la position de l’aéronef par rapport au navire doit être estimée au moyen d’autres capteurs. Une technique d’analyse d’image issue de l’état de l’art est adaptée pour détecter le modèle 3D du navire et calculer sa distance à l’aéronef. Afin de robustifier l’estimation de la position relative, une fusion d’informations provenant du capteur de vision et d’une IMU est proposée. Enfin, pour préserver l’intégrité du train d’atterrissage de l’hélicoptère, les mouvements du navire doivent être anticipés pour assurer un rendez-vous de faible dynamique. Une étude de la prédiction des mouvements d’un navire est développée. Les algorithmes de la boucle de vol sont testés à l’aide d’un simulateur réaliste
Ship deck landing is one of the most difficult maneuvers for a pilot. Turbulence, low visibility and the ship deck’s motion create a degraded environment and generate a significant workload for the pilot. The complete automation of this maneuver offers the crew a gain in safety and enables the expansion of helicopters use during maritime operations. In addition, the emergence of autonomous helicopter for observation purpose leads to the development of automatic guidance for all flight phases and in particular for ship deck landing. The studies carried out in this thesis concern an automatic deck landing system whose main function is to control the aircraft on a rendez-vous trajectory, calculated from the data of ship’s motion. Several control strategies have been evaluated, both in the linear and nonlinear domain. In an environment without GPS, the position of the aircraft relative to the ship must be estimated using other sensors. For example, vision-based sensors are a very good alternative. A state-of-the- art image analysis technique is adapted to detect the 3D model of the ship and calculate its distance from the aircraft. In order to robustly estimate the relative position, a fusion of the data from a vision sensor and an IMU is proposed. Finally, to preserve the integrity of the helicopter landing gear, the movements of the ship must be anticipated to ensure a low dynamic rendez-vous. The study of ship motion prediction is developed and leads to the comparison of three algorithms evaluated on sea data. The algorithms of the whole flight loop are first tested using a simulator before being implemented on the prototype of a drone developed by Airbus Helicopters

This study aims to investigate the development and the application of Art Deco as a style to space design between the 1910s and the 1930s in Taiwan. It particularly takes the space design of The Landis Taipei Hotel as a case study for this research. Art Deco developed from design as an art movement in France. It came into vogue for decoration in Europe and USA in the 1920s and the 1930s, and flourished in architecture in USA about the same period. This movement was further introduced into Shanghai in the eastern coast of China and developed up as the famous ‘Shanghai style’. During that period Taiwan was a colonial society ruled by the authority of the Japanese Empire which had also received the effect of Art Deco. The elements of “luxury” and “exquisiteness” found in this style are seen to be the spirits Art Deco pursued. The applications of multi-culture, classical forms and modern material, geometrical forms of decoration, and art of mechanical age all contribute to shape Art Deco as a great vogue of international importance. Design as a whole is a field that derives ideas from living culture and arts, and possesses a nature of high practicality. This research therefore focuses on investigating the style of Art Deco itself and its historical background. It will not emphasize on the history of the development of Art Deco in Taiwan, but it will examine how this particular style influences on design industry and how it was used to create a space aura in general. This research examines the interior design of The Landis Taipei Hotel which is regarded to have manipulated Art Deco in the 1960s. Two main points are listed as below: 1. How did Art Deco movement influence architecture and interior designs in Taiwan? And how did foreign culture contribute to shape an atmosphere of a space aura? 2. How were the strategies applied by the designers and the owner of the hotel to fulfill the key spirit Art Deco pursued? And how did the Hotel manage the place by adding “aura space” in restaurants to bring in a luxury, elegant and modern atmosphere to their customers. This research is done by information gathering of the historical background along with interviews with the Hotel managers, and personal visits of the scene. This research may contribute fresh arguments on understanding the development of Art Deco in general and the idea of Space Aura specifically in Taiwan. Key Word：Art Deco, Aura, Interior Design,

Resumen
Lisa Lindquist Dorr tells the story of the vast smuggling network that brought high-end distilled spirits and, eventually, other cargoes (including undocumented immigrants) from Great Britain and Europe through Cuba to the United States between 1920 and the end of Prohibition. Because of their proximity to liquor-exporting islands, the numerous beaches along the southern coast presented ideal landing points for smugglers and distribution points for their supply networks. From the warehouses of liquor wholesalers in Havana to the decks of rum runners to transportation networks heading northward, Dorr explores these operations, from the people who ran the trade to the determined efforts of the U.S. Coast Guard and other law enforcement agencies to stop liquor traffic on the high seas, in Cuba, and in southern communities. In the process, she shows the role smuggling played in creating a more transnational, enterprising, and modern South.

Resumen
A strategic capability of contemporary naval ships is the ability to launch and recover embarked aircraft such as helicopters in a maritime environment. Such operations are enormously challenging due to deck motion, limited landing space, visibility, ship’s superstructure, etc. This places extreme pressure on the pilot, ship’s crew and the platforms alike, making such shipboard operations the most dangerous of all helicopter flight missions. Therefore, the design and integration of equipment, systems and aids to ensure such operations are done as safely as is practicably possible, presents ship builders, aircraft manufacturers, engineers and pilots with some extremely demanding and complex problems. Major naval ship design/build programmes that include an aviation capability, will inevitably need to engage resources across multiple disciplines that include, but not limited to; engineering, design, logistics, administration, procurement, legal, alliance partners and the customer to manage project risks from the outset. This research highlights the need for a holistic/Systems Engineering approach that recognises risks across the wider ship programme, that can only be managed/resolved by cross-discipline collaboration. This paper presents a novel methodology to elicit risks qualitatively and models the relative risk profile of an aviation project throughout the ship programme lifecycle. The use of an enterprise model based on the three ‘P’ element methodology (3PE): Product, Process, People within an environment has been developed. Furthermore, the research outlines a continuous management and visualisation approach that enables a process of dynamic analysis to both reduce and/or mitigate residual risks progressively throughout the project lifecycle to acceptable levels.

Resumen
Abstract Clearly, humans operate in a social world. Our close relationships are those in which we derive some of our deepest gratifications as well as our most profound sufferings. It is no wonder that scientists have studied the importance of close relationships to human functioning across the life span (see Reis, Collins, & Berscheid, 2000, for review). Indeed, theoretical and empirical accounts of psychological well-being assert that strong and stable social ties with others are central components of psychological health (e.g., Deci & Ryan, 1985; Ryff, 1995). Further, research has also clearly shown that close relationships are crucial for physical health, so much so that the lack of close bonds is a risk factor for health on par with other risks such as cigarette smoking, high blood pressure, and obesity (House, Landis, & Umberson, 1988).

Resumen
The operation of helicopters on ships is one to most challenging tasks due to adverse weather conditions, the lack of visible cues, turbulent airwakes behind the ship and a moving confined landing spot on the ship. Currently, only a very limited number of pilot assistance systems are available to ease helicopter ship deck landings. The focus of this paper is the evaluation of a Head-DownDisplay(HDD),aHead-MountedDisplay(HMD)andtwodifferentAttitudeCommand Attitude Hold (ACAH) flight control architectures for ship deck landings based on piloted simulation. A ship deck landing scenario at the research flight simulation facility Air Vehicle Simulator (AVES) has been extended to include turbulent ship airwakes from high-fidelity Computational Fluid Dynamics (CFD). The pilot assistance systems have been implemented at the simulator and evaluated by four helicopter pilots. In particular, the results show a favorable potential of the Head-Mounted Display and the flight control architectures.

Resumen
This work is a continuation of the ship-deck landing research presented at VFS Forum 2021, which established a vision-based method to track ship-deck motion before landing when conditions are favorable. This paper makes advancements on two fronts: 1) Demonstrating the effect of velocity feedback on tracking stochastic deck motion, and 2) Developing a new feature-based vision system to detect and track decks in a wide range of challenging environments. The new vision system can detect decks in occlusion as high as 95%. It can also handle a wide range of illumination conditions varying from 20,000 lux of a bright day to 0.01 lux of a dark room. Moreover unlike fiducial-based vision systems that require a custom well designed marker or tag to work, the new vision system can work with generic ship-decks or landing platforms.

Resumen
This paper describes the development and implementation of newly designed helicopter ship deck landing control modes and their evaluation in a piloted simulation study. The ship deck landing modes are embedded in a model following controller architecture. The employed control design is a complete model-following control system which imposes the desired command model dynamics on the controlled helicopter. Different command types combined with various hold functions are implemented to make the task easier for the pilots. Three basic command types and three advanced command types, one without ship communication and two with ship communication, are implemented. A piloted simulation study was performed in a simulator to evaluate and compare the implemented control modes within a complete maritime scenario design. The evaluation of control modes is based on the success of helicopter ship deck landings which is assessed by a quantitative as well as a qualitative assessment. Simulation results demonstrate that the advanced command types improved the task performance as well as reduced the pilot workload extensively in comparison to the basic command types.

Resumen
This paper presents the results of an extensive model-scale experimental evaluation of autonomous ship landing guidance and control modes, with flight tests performed in the Maneuvering and Seakeeping (MASK) Basin at the U.S. Naval Surface Warfare Center Carderock Division. The experiments were performed using a commodities-based multirotor UAV operating from a 20-foot-long model scale ship subject to scaled wave conditions. During testing, two separate guidance algorithms were evaluated: a quadratic programming (QP) based landing algorithm that plans the trajectory to a forecasted deck state, and a simpler 'baseline' method that tracks deck motions while closing the distance between the aircraft and deck at a constant rate. Both algorithms commanded a Froude scaled explicit model following control law, and the control laws were used to progressively degrade aircraft tracking bandwidths. The results showed the QP algorithm to be capable of good performance despite poor long term deck state predictions, though several landings with the QP algorithm did terminate with significant velocity and attitude errors. In these cases, however, it is shown that the major factor contributing to degraded performance was not poor deck predictions, giving confidence in the feasibility of incorporating deck predictions directly in path planning. The results also showed that the predictive capabilities of the QP algorithm allowed more direct landing paths to be planned when compared to the baseline algorithm, and also allowed the QP algorithm to land with lower tracking bandwidths. The baseline guidance algorithm, on the other hand, proved to be both simple and reliable when the UAV was in high bandwidth configurations but is sensitive to increased lag in the system.

Resumen
This paper describes the development of avionics and control systems, followed by flight demonstration for vision-based landing of a multirotor UAS on a moving platform replicating a ship-deck. The UAS is a quadrotor designed and fabricated in-house with an integrated avionics package developed for autonomous vision-based navigation. A monocular camera is used for detection and pose estimation of a moving platform. The platform replicates ship-deck motion using six degrees of freedom capable of oscillatory motions upto 10 cm in linear and 30 degrees in angular amplitude with speeds upto 50 cm/s. Ship-deck motions of progressively increasing intensity were obtained from ONR and simulated using the moving platform to understand the problems involved in estimation and tracking of large stochastic motions. Results were verified with an independent Vicon system. The key conclusion is that it is possible to track a moving ship-deck with vision alone. Indeed vision based ship-deck position estimation was found to be near perfect with errors of 1-2 cm. Ship-deck tracking shows a phase lag error that increases with increasing frequency of ship-deck motion. It was found that this error can be decreased by estimating ship-deck's velocity and using it as a feedback in tracking controller.
