The Oblique Detonation Wave Hypervelocity Scramjet(ODW Hy-Scram) Engine is applicable to hypersonic flight vehicles that require high Mach Scramjet operation. This project will implement a unique new analysis capability to analyze and assess a novel propulsion device that could greatly enhance applications in the hypersonic class of flight vehicles. The ODW Hy-Scram Engine is configured to use gas ...

The capability to identify radar signals from enemy fighters about to launch a semi-active air-to-air missile would allow jamming before launch. If the attacking radar could be recognized within the first several pulses, the aircraft under attack would have this capability. Advent Systems proposes a nonconventional approach to the identification problem by using both intrapulse and c ...

Degraded performance due to surface damage of aircraft windows and antennas caused by atmospheric particle effects is currently a very serious problem. Impact testing is currently underway in ground test cells such as the wind tunnels and arc facilities located at Arnold Engineering Development Center (AEDC). For these tests, instrumentation that can determine the velocity vectors and size distrib ...

As the size of staring sensors increase, the bandwith to move data off the focal plan increases proportional to the number of pixels in the array. For analog focal planes increased bandwidth also means increased noise. Readout noise limited systems will be less sensitive, detector noise limited systems may become readout limited at the higher bandwidths. Power dissipation will also increase wit ...

We propose a highly accurate surface profile data collection device that can be used to measure the buildup of ice on aero-surfaces. The device will be able to remotely collect the required data in a very short time and can be used for measurements of both static or rotating surfaces. By combining moire topography, a pulsed laser, and a digital data collection system, surface characteristics of ...

Carbon-carbon is a unique composite material that achieves the highest in-plane thermal conductivity and also achieves very high young's modulus (40-50 MSI). This research project will demonstrate the feasibility of C-C as an effective heat sink material for electronic packaging. Three to five carbon-carbon materials will be designed and analyzed in the required packaging configuration with approp ...

A program is proposed to develop data processing routines for adaptive optics. These routines will be such that they run on a PC, such as a 486, and are compatible with commercial software packages, such as MATLAB, Matrix X, or Control C. A key feature of this work is the breadth of experience that the Optical Sciences Company has in both adaptive optics testing/analysis and software development. ...

Avyd Devices proposes a Molecular Beam Epitaxy (MBE) growth based HgCdTe heterostructure photodiode approach to develop a technology capable of producing VLWIR HgCdTe arrays with high performance, high tolerance to nuclear radiation, high uniformity, high operability, and high yield for use in low background space environments. These essential elements of the approach entail: ¿ Heterostructure g ...

A full scale application of shape memory alloys in intelligent structures requires that the complex interaction between active elements (sensors, actuators, processors) and the host material be investigated. In the proposed research, i) constitutive equations to model the behavior of shape memory alloys under large deformations will be developed, ii) composite laminates will be modeled as a contin ...
