Повний текст джерелаLuftskepp var mycket populär för 90 år sedan, till exempel med tyska Zeppelinare. Nu ärde tillbaka av flera skäl, som deras låga energiförbrukning.Men det finns fortfarande många problem att hantera som deras känslighet för vindbyar.Dessutom behöver luftskeppen fler studier för att förbättra sina flygegenskaper och vindkänslighet.Detta examsarbete, utfört vid den franska institutionenONERAi Lille, studerar ett specifiktluftskepp som är 5 m långt och 1.7 m brett. Först, studeras luftskeppet utan vind för attbestämma aerodynamiska data och tröghetsegenskaper. Sedan genomförs experiment därmodellen utsätts för vindbyar.

This project aims to develop MEMS actuators to aid in the study of insect flight mechanics. Specifically, we are developing actuators that can stimulate the antennae of the crepuscular hawk moth Manduca Sexta. The possible mechanosensory function of antennae as airflow sensors has been suggested, and recent discoveries of our collaborators reveal that mechanosensory input from the antennae of flying moths serves a similar role to that of the hind wings of two-winged insects, detecting Coriolis forces and thereby mediating flight stability during maneuvers. Early evidence suggests that mechanical stimulus of the antennae may enable flight control. In addition, the crepuscular hawk moth Manduca Sexta has a wide wingspan (~110 mm) and is capable of carrying at least one quarter of its own weight. Thus, studying the flight of Manduca Sexta by attachment of microsystems seems plausible. The goal of our project is to design and fabricate micromechanical actuators, which will be mounted onto the moth antennae. Our collaborators will study the flight control mechanism by mechanical stimulation. Our first step was to fabricate "dummy" silicon rings for our biologist collaborators for implant experiment. A series of mounting kits were developed, and due to the nature of the moth antennae, ring-beam-ring construction was finally designed and fabricated, like a "shackle", to meet the mounting requirements. Next, we integrated actuators onto the mounting kit. Piezoelectric film/sheet, piezoelectricbender and piezoelectric-stack were considered as the actuators. Live testing was also taken while the moth was resting or flapping its wings. The moth apparently responds to the mechanical stimulus under both circumstances, by swinging its wings and abdomen. Actuation amplifier was also modeled and tested, which might be used for future mechanical stimulators.

Повний текст джерелаVid flygplanskonstruktion krävs hårt och noggrant arbete för att säkerställa gott resultat. Ett oumbärligt verktyg är då en flygmekanisk simulator. Den typen av simulatorer är ofta uppbyggda av moduler/modeller som exekveras i en bestämd sekventiellt ordning i varje tidsteg. Syftet med detta projekt är att undersöka möjliga förbättringar av exekverings ordningen av de olika modellerna i en existerande simulator, baserat på beroendestrukturen. Analysmetoden Design Structure Matrix (DSM) användes för att bestämma beroendestrukturen och sedan utnyttjades Binär Linjär Programmering (BLP) för att hitta fem förbättrade modellordningar med avseende på att minimera antalet modeller som erhåller indata från föregående tidsiteration. De fem förbättringsförslagen jämfördes och utvärderades. Resultatet är en modellordning som kan minska antalet återkopplande modeller från 13 till 6, med insignifikanta skillnader i precisionen av simulatorn.

Повний текст джерелаBITAK - SAGE. In FML, flight profiles of projectiles are reconstructed using their tear marks on paper sheets, called yaw cards. Tear marks are created on yaw cards as projectiles pass through them. These yaw cards are tightly stretched to metal frames which are positioned normal to the direction of projectile flight path. The use of yaw cards for flight profile reconstruction is a low cost and reliable solution. However, the yaw card method requires a heavy workload for the analysis of tear marks. Yaw cards collected from the frames are fed through an optical scanner and converted to digital images. These digital images are then processed by operators to calculate the projectile&rsquo
s flight position and angles. To automate this manual process, an algorithm is developed by using histogram based segmentation techniques, custom search algorithms, and Radon transform. This algorithm identifies and locates the projectile marks and finds angle of attack, angle of side slip and roll angle at each frame station by conducting the necessary transformations. Using this automated algorithm, a considerable amount of improvement is accomplished in terms of both decreasing the analysis time and increasing the accuracy of flight profile reconstruction.

Повний текст джерелаA universal time of flight equation for any orbit is developed as a
function of the initial and final radius, the change in true anomaly
and the initial flight path angle. Lambert's theorem, a new corollary
to this theorem, a trigonometric variable substitution and a continuing
fraction expression are used in this development. The resulting
equation is not explicitly dependent upon eccentricity and is
determinate for -2n < (change in true anomaly) < 2n. A method to
make the continuing fraction converge rapidly is evaluated using a top
down algorithm. Finally, the accuracy of the universal time of flight
equation is examined for a representative set of orbits including near
parabolic and near rectilinear orbits.

Levy flights have been recently found to approximate the trajectories of animal foragers in their search for resources and food. Levy flights have proved to be effective in searching tasks because of their characteristic combination of long trajectories followed by bursts of short trajectories. In addition, some developments in robotics are currently geared toward robot miniaturization and mimicry of living creatures. For example, robots based on the features of hummingbirds and bees have already been developed though they are not yet autonomous. Incorporating Levy flight searching strategies into these miniaturized robots could yield more efficient and effective searching machines.

Повний текст джерелаFormation flight has been shown to reduce the induced drag for a formation of aircraft. The mechanism by which this is achieved is caused by the wake velocity field of the aircraft. This field is dominated by wing-tip trailing vortices. The paths of these vortices become too complex for rigid wake models downstream of the second aircraft in the formation. To tackle this problem, a combined vortex lattice and vortex filament numerical model was developed. For each simulation the vortex lattice model determined the lift distribution which was applied to the vortex filament model. The vortex filament model used the Burnaham-Hallock vortex profile with a core size of 5% of the wing span to eliminate numerical instabilities. Individual components of the model were verified successfully against literature and the overall approach was validated against wind tunnel data. The wind tunnel data was extracted from apparatus designed and build as part of this study. The apparatus consisted of two NACA 0012 rectangular planform wings mounted in various formation positions and a tuft grid placed downstream of the wings to visualise the vortex paths. Test were performed with both wings at 8◦ angle of attack. Span-wise wing-tip overlap distances were set at 38%, 10%, 0% and -10% of the span, where 0% implies wing-tip alignment and a positive value indicates a wing-tip overlap. Vertical separations were set at -3%, 0% and 3% of the span for each span-wise wing-tip overlap condition apart from 38% which was only tested at 0 vertical separation. The formation outboard vortex paths were predicted well within the 3% span accuracy of the tuft grid. The predictions of the paths of the formation inboard vortices, however were less accurate. The errors were attributed to a combination of bias errors in the experimental apparatus as well as the pseudo-viscous effects of the Burnham-Hallock vortex profile.

Повний текст джерелаDans le cadre de la mécanique des fractures, nous présentons une méthode d'éléments finis qui simule le bris de la glace accumulée sur les ailes d'avions, en deux dimensions, ainsi que le délestage du givre accumulé sur les pales de l'hélicoptère, en trois dimensions. Le module de bris de glace, entièrement automatisé, est intégré en FENSAP-ICE [1-2], un logiciel de simulation qui résout séquenciellement le flux, l'impact des gouttelettes et le cumul de glace. Les modules bidimensionnels et tridimensionnels de propagation de fissures sont développés et validés par comparaison avec des résultats expérimentaux sur une plaque fissurée d'un seul côté, ainsi que pour un spécimen entaillé d'un seul côté avec une charge de flexion en trois points. Plusieurs formes de glace sont analysées et des comparaisons faites avec un autre code traitant la mécanique des fractures. Dans des conditions typiques de givrage et d'écoulement, l'élasticité linéaire s'est avérée adéquate pour une analyse du bris de glace. Pour la glace accumulée sur les ailes, une conclusion importante de cette étude est que le bris de glace dépend fortement de sa forme, c'est-à-dire que pour des charges aérodynamiques similaires, certaines formes de glace briseront, tandis que d'autres ne le feront pas. En ce qui concerne la glace accumulée sur les hélicoptères, il a été conclu que les facteurs les plus importants pour le bris de glace sont la vitesse rotationnelle de la pale et la force d'adhésion entre la glace et la pale. L'objectif principal de cet ouvrage est d'analyser des phénomènes multi-physiques complexes et de fournir un modèle simplifié du bris de la glace pour les utilisateurs industriels et les concepteurs en aéronautique. L'utilisation de cet outil n'est toutefois pas limitée à l'aérodynamique, puisqu'il peut être employé dans des domaines tels que les sciences environnementales, les sciences des matériaux, la glaciologie et l'analyse des tremblements de terre et de rupture.

Formation flight is currently being investigated as a means to reduce drag and improve fuel efficiency in commercial aviation. In light of this, the potential for passenger discomfort due to the formation flying through free air turbulence was considered in this study. In an attempt to approximately ascertain the increase in discomfort, a simple formation flight aerodynamic model for two aircraft in formation was developed. The wing trailing vortices were assumed to shift in an ideal fashion within atmospheric turbulence resulting in aerodynamic disturbance loads acting on the trailing aircraft. As the sensitivity of the human body to vibrations is frequency dependent, spectral representation of atmospheric turbulence was incorporated. Monte Carlo simulations were done for various levels of turbulence intensity.

Повний текст джерелаCette thèse examine le dynamique et contrôle d'un dirigeable autonome, extrêmement manoevrable, dépourvu d'ailerons et presque plus léger que l'air (ALTAV). Ce dirigeable est intrinsèquement instable dû à l'absence de surfaces stabilisatrices et aussi très succeptible au vent. Quatre propulseurs vectorisés sont utilisés pour assurer la stabilité en boucle fermée. Cette thèse concerne les améliorations au modèle dynamique existant, incluant l'incorporation des moments d'amortissements rotationnels du dirigeable, la traînée résultant des protubérances du dirigeable, les torques de réactions et moments gyroscopiques sur le dirigeable dû aux propulseurs. Des essais à boucle ouverte et boucle fermée ont été conçus et effectuées pour valider les paramètres physiques estimé empiriquement, et, en général, un bon accord a été obtenu. En outre, une suite de contrôle incluant un contrôleur à bas niveau et un contrôleur d'orientation de haut niveau a été conçu et mis en oeuvre pour l'opération autonome du véhicule. Les essais expérimentaux ont été effectués pour valider la performance de la suite de contrôle en présence de vents variables. Cet ensemble de contrôle a été c'est démontré fiable même sous l'influence de vents de vitesses comparable à la vitesse du dirigeable.

For centuries, the human race has been perplexed by the various complex physical manifestations in nature. Much of what we have seen in nature we have tried to recreate, from the migration tendencies and routes of sea creatures to the flight of birds and insects. The flight of the fly, in particular, is of interest because of their natural stabilization techniques. The works of two scientists, Steven Vogel and Michael Dickinson, were researched in order to find out how the flight dynamics of the fly worked. It was found that the fast horizontal wing beating of the fly as well as the body angle of the fly helped to generate lift and thrust within the fly. Equilibrium was achieved due to the haltere of the fly, a small stubby organ behind the forewing which detected Coriolis forces at the base of the wing and created counter-rotations. Both scientists used work done by earlier scientist J.W. Pringle, who modeled the haltere as a mass-dashpot-spring system using dynamics in order to analyze the oscillatory motion and how it affects flight. The research done by all three scientists can serve to one day be able to produce micro aerial vehicles, using the flight dynamics of the fly as the basis of the flight of these vehicles.

Möjligheten att simulera och utvärdera under tidens gång har stor betydelse både ur tid- och kostnadsbesparings perspektiv men även ur flygsäkerhetsperspektiv när det är dags för första flygning. Syftet med det här projektet är att utveckla en metod för jämförelse mellan simulering och flygprov för att validera hur bra den flygmekaniska simulatorn kan förutspå flygplansbeteende. En viktig del i projektet syftar till hur skillnader i resultaten kan hittas och analyseras, till exempel skillnader mellan olika flygplansindivider eller lastkonfigurationer.

Hovering is normally achieved using a horizontal wing path to create lift; bees, wasps and helicopters use this technique. Dragonflies hover using a unique method, by flapping along an inclined stroke plane. This seems to create a higher efficiency than is possible for normal hovering. The aim of this project is to build a mechanical model to mimic the aerodynamic properties and hovering motion of dragonflies. Through the design and evaluation of this model, we can evaluate the mechanical feasibility of reproducing the wing path using single motor control and establish whether the difference in stroke plane is advantageous for the dragonfly. By adjusting the initial angle of attack of the ornithopter's wings, we can artificially recreate varying stroke planes. A comparison of the resultant lift generated from different stroke planes showed that greater lift forces were generated with non-zero stroke planes as demonstrated in normal hovering.

It is experimentally known that the flight lengths of random searches by foragers such as honey bees statistically belong to a power law distribution. Optimality of such random searches has been a topic of extensive research because knowing their optimal parameters may help applied sciences. Viswanathan et al. have shown the inverse-square power law to be the optimal law for such random searches. This thesis explores the capability of the model presented in such that it can be applied to Unmanned Autonomous Vehicles (UAVs). The thesis also identifies the minimum flight length, lmin, as an important factor that needs to be controlled based on the UAV's sensor range. We present a theoretical lmin as an explicit function of the sensor range, rv, and an estimated target density, p.
