A new tool calculates vehicle aerodynamic flight parameters from observed flight trajectory. These flight-observed parameters are then compared to the expected aerodynamic parameters for a nominal vehicle flying the same trajectory. The differences in the observed versus expected aerodynamic parameters...

This collection of C++ classes allows users to create and simulate aerospace vehicle models that are needed to test prototyped display software. A software model of the Apollo LEM spacecraft was developed on a Windows-based PC, and was used for initial testing and research of cockpit displays. The model was...

Autonomous operations of small unmanned aerial vehicles, or UAVs (quadrotors), require safety modules to alert a human operator of a critical system state, or even take over control of the vehicle entirely to initiate a pre-defined safety maneuver during an emergency (e.g. an emergency landing when a radio link is...

This innovation is an airborne area security search system and method that features a two-phase search from an unmanned aerial vehicle (UAV) using a novel combination of sensor technologies not previously employed. Its key strength is a wide-area search at high resolution for reliable identification of objects. It...

An aircraft trailing edge device, coupled with an aircraft wing, provides a reduction in jet-flap interaction noise while preserving the aerodynamic load capacity of the trailing edge. Embodiments of the present invention provide a trailing edge flap device that includes a center flap...

The purpose of the invention was to increase the operational power levels of solid-state power amplifiers using state-ofthe- art power amplifier design and combining methodology. Using 1-kW RF modules and proper RF combining techniques, a system was built that generated 16 kW of RF power for use in...

Theodolite autocollimation metrology continues to play an important part in spacecraft optical alignment. Spacecraft optical alignment is both art and science for using optical instruments to place or determine the orientation and envelope of critical components on...

A new method of molecular sexing is described that helps to understand population dynamics of the Florida Scrub-jay (FSJ). FSJ is an endemic, nonmigratory, monomorphic species of bird found on the Florida peninsula in lowgrowing oak or pine scrub. The current conservation status...
