Potential cost effective proprietary solutions to a number of outstanding problems involved in achieving an SBR capable of meeting military surveillance and reconnaissance requirement for the detection and track of both ground and airborne moving targets are proposed to be further developed and space-time adaptive processing SBR. Performance e ...

We propose to engineer a low-cost computer-controlled optical diagnostic system for measuring sound speed, thermal diffusivity, density, and velocity. This system will use laser-induced thermal accoustics (LITA), a transient-grating technique capable of making accurate single-shot measurements in luminous, multiphase, high-pressure flows. The LITA signal intensity is quadratic in fluid density f ...

The Pulse Detonation Engine (PDE) is an intermittent combustion engine that relies on traveling detonation waves for the combustion and compression elements of the prosulsive cycle. This engine may be used as a low cost propulsion system in defense flight vehicle system applications or as the low speed cycle for a high Mach number combined cycle engine system. The mechanical simplicity of this e ...

The goal of this two-phase program is to develop a prototype system which addresses the problem of nondestructively extracting layout patterns for multilayer printed circuit boards. The system will use x-ray digital tomosynthesis for image acquisition, and advanced image processing, including morphological operators, to extract circuit features from the images. The objectives of Phase I are to 1 ...

The creation of digital design information for the manufacture of existing parts is a critical need for maintaining part inventories and to ensure the reliable operation of critical equipment. Such parts, which are frequently found in aging military aircraft, pose an important challenge to the Air Force's resupply operations. Current methods for obtaining the surface geometry of parts do not ad ...

The Skytote concept has emerged from a system analysis seeking a remotely/ autonomously controlled air vehicle for transporting materials -- a vehicle system that emphasizes simplicity, economy, and versatility. In one version it is envisioned as a ing less than 250 lbs) that does not require any physical conversion of configuration going from vertical takeoff to hig ...
