Streszczenie:

Uninhabited aerial vehicles are aircraft without the onboard presence of pilot or aircrew. Even though the human is removed from the direct control of the aircraft, the human is typically involved in the process as a supervisor in a multiple task telerobotics control system. The supervisor must receive the appropriate information for efficient decision making and input the information required to augment the autonomous control of the vehicle as necessary. This article presents an approach that applies human operator modeling methods to perform semiotic analysis and identifies the content and form of the information required for effective supervisory control. This paper also outlines a computational modeling and simulation architecture that supports concurrent multi-user connectivity and reconfigurable user interfaces. The potential utilization of this architecture to systematically evaluate interface concepts and the role of automation in these systems is also described. Finally, an empirical evaluation is described that benchmarks the effectiveness of the architecture.Human-Integrated Supervisory Control of Uninhabited Combat Aerial Vehicles.

Streszczenie:

The performance of small uninhabited aerial systems (UAS) is very sensitive to the atmospheric state. Improving awareness of the environment and its impact on mission performance is important to enabling greater autonomy for small UAS. A modeling system is proposed that allows a small UAS to build a model of the atmospheric state using computational resources available onboard the aircraft and relate the atmospheric state to the cost of completing a mission. In this case, mission cost refers to the energy required per distance traveled. The system can use in situ observations made by the aircraft, but can also incorporate observations from other aircraft and sensors. The modeling system is demonstrated in a flight test aboard a small UAS and validated against radiosondes and numerical weather model analyses. The test demonstrates that the modeling system can represent the atmospheric state and identifies times where significant error exists between the state expected by the numerical weather model and that observed. Transformation of the atmospheric state into a mission performance cost identifies cases where the mission performance cost predicted by a numerical weather model differs from that observed by more than 30%.

Abstract During the 1998 and 2001 hurricane seasons of the western Atlantic Ocean and Gulf of Mexico, the Advanced Microwave Precipitation Radiometer (AMPR), the ER-2 Doppler (EDOP) radar, and the Lightning Instrument Package (LIP) were flown aboard the NASA ER-2 high-altitude aircraft as part of the Third Convection and Moisture Experiment (CAMEX-3) and the Fourth Convection and Moisture Experiment (CAMEX-4). Several hurricanes, tropical storms, and other precipitation systems were sampled during these experiments. An oceanic rainfall screening technique has been developed using AMPR passive microwave observations of these systems collected at frequencies of 10.7, 19.35, 37.1, and 85.5 GHz. This technique combines the information content of the four AMPR frequencies regarding the gross vertical structure of hydrometeors into an intuitive and easily executable precipitation mapping format. The results have been verified using vertical profiles of EDOP reflectivity and lower-altitude horizontal reflectivity scans collected by the NOAA WP-3D Orion radar. Matching the rainfall classification results with coincident electric field information collected by the LIP readily identifies convective rain regions within the precipitation fields. This technique shows promise as a real-time research and analysis tool for monitoring vertical updraft strength and convective intensity from airborne platforms such as remotely operated or uninhabited aerial vehicles. The technique is analyzed and discussed for a wide variety of precipitation types using the 26 August 1998 observations of Hurricane Bonnie near landfall.

Abstract Vegetation health monitoring is key to identifying early signs of water stress, pollutant-induced toxicity, and plant diseases in green urban stormwater facilities. However, rigorous monitoring to collect accurate quantitative data is an expensive and time-consuming process. This paper examines the feasibility of using uninhabited aircraft systems (UAS), in comparison to standard ground-based methods, for monitoring biomass and primary production in two bioswale cells at an urban stormwater facility. Implementation of the UAS-based approach involved flight planning in an urban area to meet resolution requirements of bioswale imagery obtained from near-infrared and red-green-blue cameras. The resulting normalized difference vegetation index (NDVI) estimated from UAS data was tracked over a 2-month period during the transition from spring to summer, showing the spatial distribution of NDVI and the change in vegetation coverage areas over time. In comparison, ground-based measurements of the fraction of intercepted photosynthetically active radiation (PAR) presented multiple practical challenges during implementation in the field, leading to over- and underestimates of intercepted PAR. Overall, UAS-derived NDVI was found to be a valuable reflectance-based, vegetation health-monitoring methodology that can be used by utilities and cities for practical, cost-effective, and rapid assessment of vegetation stress and for long-term maintenance in green stormwater facilities.

Background: From 2016, wildfire emergency response used Remotely Piloted Aircraft Systems (RPAS) also known as Uninhabited or Unmanned Aerial Vehicles (UAVs) and Systems (UAS) or "drones" (hereafter UAS), smartphones and smartphone applications (apps) on-site, for the first time at scale in Aotearoa New Zealand (hereafter New Zealand). This study outlines the deployment and use of this new technology in monitoring at wildfires in New Zealand from 2016, and the conveyance of fire response information to operational personnel. Methods: A quantitative and qualitative questionnaire, and semi-structured interviews were used to gather feedback on the use of this emerging technology from wildfire management personnel. The results were analysed to determine perception change over time, using retrospective analysis. The issues presented, and the uptake by fire management and personnel for the incorporation of such technology at wildfires in New Zealand are discussed. Findings: The integration of UAS and visual, infrared/infrared-thermal (IR/TIR) sensors has been used at over ten wildfire management response incidents throughout New Zealand since 2016. The quantitative perception of use and benefit of information technology in wildfire management response improved from the initial viewpoints, from indifferent to strongly supportive, and supportive to strongly supportive for UAS and smartphone use, respectively. Qualitative analysis showed that both positive views on the new technology increased, and indifferent and negative views diminished substantially following exposure to its operational integration into wildfire management. Conclusions: The use of technology such as UAS has gained support and currently offers the potential to increase safety and reduce suppression and mop-up costs. A reduction in the time taken for hotspot detection and management, combined with the ability to redeploy heavy-lift aircraft away from such tasks would lead to efficiencies in cost and resource utilisation. UAS as platforms for remote-sensing devices (such as cameras and laser scanners), and smartphone apps are now considered important tools for deployment at New Zealand wildfires by operational and Incident Management personnel. The adoption of any new systems or technology requires flexibility, especially in terms of management support, in which regular information, training and instruction should be considered crucial.

A considerable amount of research effort has, and continues to be invested into technologies and algorithms for capabilities which are forecast to be needed in future uninhabited vehicles. Much of this research is conducted with the aim of increasing the level of autonomy of these vehicles. However these technologies and capabilities provide only a part of the total system solution and must be integrated into an architecture that covers the entire vehicle system. This total system approach is particularly relevant since this is how airworthiness regulators consider Uninhabited Aircraft Systems. Airworthiness of uninhabited aircraft has been addressed by Australian aviation regulators. While the regulations may be in place, technical challenges still remain for the suppliers of these systems. For example, one of these unresolved technical challenges is the capability of uninhabited aircraft to

Streszczenie:

The use of atmospheric updrafts as an energy source for long endurance flight has proven to be extremely advantageous for birds, remote control sailplanes, and manned soaring vehicles. Recent research conducted by Michael Allen at NASA and Dr. Dan Edwards at North Carolina State University has demonstrated the viability of using a UAV to search for, detect, and gain altitude using thermal updrafts. This approach can be taken a step further by introducing multiple cooperating vehicles to reduce the time spent searching for thermal lift while simultaneously increasing the time spent in thermal lift gaining altitude and/or saving fuel. UAV missions calling for multiple vehicles can use this approach to reduce the demand for on board energy storage by using environmental energy more effectively than a vehicle flying alone. This research aims to complement existing autonomous soaring efforts by developing a low cost thermal soaring system that is capable of working with single or multiple cooperating vehicles to find and utilize thermal updrafts. Early simulations developed to validate this idea have given rise to further analysis and experimentation with two custom airframes, each equipped with instruments to detect updrafts and autonomous capabilities to test cooperative soaring algorithms in the real world. The system developed used a sub $1000 commercial off-the-shelf autopilot and custom ground control software to achieve many autonomous soaring flights with a single vehicle. Several flights with two autonomous vehicles were also performed and cooperative behavior was demonstrated.

Recent improvements in technology has enabled the use of very sophisticated sensors such as embedded fiber bragg gratings (FBGs) to obtain strain measurements from a variety of structural types. Conventional strain gauges tend to be heavy and bulky. Because of their accuracy, light weight, small size and flexibility these fiber optic sensors have big potential to be used in space exploration and the aerospace industry especially for flying aircraft that have strict weight and size limitations. These strain measurements can be used to predict the deformation shape of aircraft during real-time flights. The development of such methods for monitoring and control can potentially reduce the risk of in-flight breakups, such as that of the Helios Wing. The Structures, Propulsion, And Control Engineering (SPACE) NASA sponsored University Research Center (URC) of excellence has concentrated in the development of small, lightweight Uninhabited Air Vehicles (UAVs) that have excelled in the area of endurance. Today, the UAV project is focused on the design of a multi-mission multipurpose air system that can operate autonomously. The configuration is a twin boom, pusher, and conventional wing design. In this paper, methods developed by the National Aeronautic and Space Administration (NASA)’s Dryden Flight Research Center for real-time deformation shape prediction of lightweight unmanned flying aerospace structures for the purposes of Structural Health Monitoring (SHM) and condition assessment are investigated. SHM may allow for useful monitoring that would prevent such an event by providing wing shape information and structural monitoring to either a pilot or the flight system, allowing for evasive maneuvers before the breakup would occur. These methods also have the potential for increasing safety, allowing monitoring of structural integrity, detecting damages, and providing real-time flight control feedback. These methods are applied to the SPACE Center UAV for the purpose of assessing the effectiveness of the method and the potential for both SHM and control applications. In this paper, a computational finite element model of the SPACE Center UAV is developed and used to examine the method.

In September of 1994 a small uninhabited aerial vehicle took to the air. While the flight of this lightweight powered glider was unremarkable, its 3 minutes aloft represented a turning point in adaptive aerostructures technology as it was the first man-made craft to stay aloft while using only adaptive materials for all flight control. This paper celebrates and summarizes two decades of flying adaptive aerostructures controlling missiles, munitions and UAVs. The paper starts with an historical review of the technologies which underpinned the first adaptive flight vehicles. Twist-active piezoelectric plates are shown beside the earliest flightweight stabilators they were integrated into. A brief description of the 120cm wingspan UAV “Mothra” which took to the air 20 years ago is given. The earliest hard-launched adaptive actuators were designed and developed just a year after Mothra took to the air. The paper summarizes the resulting (unrestricted) adaptive actuator configurations which have come around since that time, including actuator assemblies for guided bullets and cannon shells from 5.56mm through 155mm. A decade ago, the first post-buckled precompressed (PBP) piezoelectric flight control mechanisms debuted as enabling technologies in a unique class of aircraft: “hovering missiles” flew at international airshows, guided rounds hit targets on gunnery ranges and entered serial production with PBP actuator assemblies. More modern incarnations of these actuators and others have been designed into GPS-guided grenade, mortar and artillery shells. Today, some of the world’s most active and highest work energy density actuators are built with ultra-high strain adaptive materials and have been shown to dramatically cut CEP of gravity weapons, cruise missiles and glide shells. The paper concludes with a chart showing which classes of adaptive actuators have been flown in what types of weapon systems and UAVs over the past 20 years.
