 | We summarize progress in our analysis of proposed communication schemes for hypersonic vehicles in flight. Investigations into the electron-acoustic wave (EAW) communication scheme have yielded a dispersion analysis indicating that EAW modes can be generated and propagate in the plasma layer [D. V. Rose et al., Voss Sci. Rep. No. VSL-0737, Nov. 2007]. These modes can be coupled to electromagnetic waves at the plasma layer boundary for the assumption of ... |

|
| The United States Air Force has advanced fighter aircraft that lose the ability to operate in a large portion of their operating flight envelope when an air data system failure is experienced. These aircraft are reverted to a fixed set of standby-gains that limit their maneuverability, degrade handling qualities, and increase susceptibility to departure. The purpose of this research was to determine if three alternative methods of standby-gain-scheduling could provide ... |

|
| Interest in the development of super-maneuverable, micro-air-vehicles has led to the re-examination of basic flight modes, particularly, those that are inspired by biological observations. The majority of experimental and numerical studies related to flapping flight have explored the relationships between the thrust coefficient (and propulsive efficiency) and wing geometry and kinematics. Relatively speaking, the wing flexibility and the interplay between kinematics and flexibility have received less attention, and currently, it ... |

| Since as early as the 1940's, specialized structures on dipteran insects have been recognized as necessary for inertial measurement associated with basic flight stability. These structures, called halteres, have been suggested to act as vibrating structure gyroscopes, measuring strains proportional to Coriolis accelerations. As a miniature, robust means for stabilizing flight, this biological inertial measurement system is not only of interest to biologists, but also to designers of biomimetic robotic ... |

| Unmanned aerial vehicle and smart munition systems need robust, real-time path generation and guidance systems to avoid terrain obstructions, navigate in hazardous weather conditions, and react to mobile threats such as radar, jammers, and unfriendly aircraft. In Phase 1 of this STTR project, real-time path planning and trajectory generation techniques for two dimensional flight were developed and demonstrated in software simulation. In Phase 2 these algorithms were refined, extended and ... |
