Flying free
Phillip Grier, architect and artist has told his students they should visit White Gables Hotel in order to understand the significance of urban and architectural planning. It is there he encounters Jenny who, seeking temporary accommodation, has taken her lecturer's advice. Their meeting is unusuaL …

The flying Dutchman
… legends of the Cape of Good Hope, that of The Flying Dutchman and Adamastor, through the medium of fiction. The author attempts an imaginative retelling of these legends by having them play out in the year 2012, recasting an old story for a new age, while remaining close to their geographical …

Jackson's Flying Dutchmen: The Significance of the Royal Netherlands Military Flying School
… Base. Known as the Royal Netherlands Military Flying School, the training the Dutch conducted helped rebuild the Royal Netherland Air Force and the air component of the Royal Netherland Navy. The Dutch military came to Jackson because they lost their territory to foreign invaders. Furthermore, …

Autonomous Controls Algorithmfor Formation Flying Of Satellites
… photographs of observable terrain. Formation flying itself has many possible uses for future applications. Selected missions that require imaging or data collection can be more economically accomplished using smaller multiple satellites. The MET thruster is a very efficient, but low thrust …

Relative Position Control for Satellite Formation Flying
Satellite formation flying is a field where the relative positions between two or more satellites are tightly controlled. It is a relevant and growing field that enables missions that otherwise might not be achievable using a single monolithic satellite. This thesis focuses on designing and …

Subpixel multiframe registration for formation flying spacecraft
… The algorithm is developed with formation flying applications in mind, where such motion is common. The algorithm is non-iterative (obtaining a registration estimate in a fixed amount of time), efficient (requiring only FFT and spatial scaling operations), and parameterless (requiring no …

Model predictive control for formation flying spacecraft
Formation flying is an enabling technology for many future space missions. This thesis addresses some of the key dynamics and control issues expected in future missions by pursuing two areas of advancement: extensions of relative linear dynamics models and assessment and mitigation of sensor noise …

Radiation dose to the global flying population
… dose received by the worldwide civilian flying population. We simulated flights globally from 2000 to 2013 using schedule data, applying a radiation propagation code to estimate the dose associated with each flight. Passengers flying in Europe and North America exceed the International …

Propulsion considerations for supersonic oblique flying wings
… considerations unique to the supersonic oblique flying wing, including cycle selection, sizing, and integration were investigated via the development and interrogation of aerodynamic and propulsive synthesis models. These models were an amalgamation of computational tools (MSES), linearized …

A SEMANTIC TOUCH INTERFACE FOR FLYING CAMERA PHOTOGRAPHY
… cameras widely used today, a camera mounted on a flying drone affords the user much greater freedom in finding the point of view (POV) for a perfect photo shot. In the future, many people may take along compact flying cameras, and use their touchscreen mobile devices as viewfinders to take photos. …

Optimal orbit transfers for satellite formation flying applications
… from the application of satellite formation flying, and obtained three major results. First, the dissertation proposed an algorithm for finding a multi-impulse, fuel-optimal trajectory, based on relative motion dynamics, and the necessary conditions from the Pontryagin Maximal Principle. …

Dorsal wing-flip timing in tethered flying locusts
… digital cinematography sequences of tethered flying locusts were stimulated unilaterally with high-frequency sounds in a subsonic wind tunnel. These sequences were used to compute left and right forewing stroke kinematics in 3D. Our results show: 1) that locusts either rapidly pronate both …

Descending premotor target tracking systems in flying insects
… often innate and highly stereotyped. Predatory flying insects present an extreme example, performing complex visually-guided pursuits of small, often fast flying prey over extremely small timescales. Furthermore, this behaviour is controlled by a tiny nervous system, leading to pressure on …

Conceptual Design for a Laminar-Flying-Wing Aircraft
The laminar-flying-wing aircraft appears to be an attractive long-term prospect for reducing the environmental impact of commercial aviation. In assessing its potential, a relatively straightforward initial step is the conceptual design of a version with restricted sweep angle. Such a design is the …

Flying snakes: Aerodynamics of body cross-sectional shape
Chrysopelea paradisi, also known as the flying snake, possesses one of the most unique forms of aerial locomotion found in nature, using its entire body as a dynamic lifting surface without the use of wings or membranes. Unlike other airborne creatures, this species lacks appendages to aid in …

Formation Flying Performance Measures for Earth Pointing Missions
Clusters of low-performance spacecraft flying in formation may provide enhanced performance over single high-performance spacecraft. This is especially true for remote sensing missions where interferometry or stereographic imaging may provide higher resolution data. The configurations of such …

Flying knights or Flying scientists? a cognitive history of the US Air Force Fighter Pilot in air-to-air combat, 1950-1980
… on other tasks deemed more vital, such as flying itself. The pilots, however, soon realized that within air combat, their traditional flying skills were becoming less critical to their success and survival; in contrast, the skills required to operate their new fire control systems were …
