This effort joins the MEMS-based deformable mirror technology available from AgilOptics, a New Mexico small business, with the aero-optics technology of the University of Notre Dame to develop an Aero-optics Simulator. This simulator will develop a library of aero-optics patterns to simulate atmospheric distortions for test and evaluation of military or commercial beam control systems.

The rapid increase in the use of the Internet in many aspects of our lives has led to an explosive growth in the spread of malware such as computer worms, viruses, and trojans. Security tools typically examine software for the presence of malware either by looking for specific byte signatures, or (more recently) by analyzing the candidate binary’s internal logic. However, it is surprisingly easy ...

We propose to examine the necessary ingredients for the development of marketable codes which will: model the morphology of heterogeneous propellants (a packing code); calculate the thermal and mechancial properties of such a morphology or pack; simulate the combustion of the pack; predict the statistics of aluminum agglomeration on the burning pack surface; simulate the flight of these agglomera ...

Self-healing composites and adhesives would alleviate longstanding problems in aerospace structures associated with multiple types of damage mechanisms such as mechanical/thermal fatigue, microcracking, and debonding. A composite cryogenic tank based on self-healing technology would prevent leakage by sealing microcracks throughout the lifetime of the tank and enable the use of composites in this ...

MWIR avalanche photodetectors (APDs) are required in modern Air Force weapons systems to detect, recognize and track stationary and mobile targets under various atmospheric conditions against complex backgrounds. Theoretical and experimental results point toward HgCdTe as the material of choice for fabricating these devices, due to its low ratio of impact ionization coefficients. In Phase I we per ...

In this proposal we exploit the remote sensing attributes of ultrasound to measure temperature, transient temperature and heat flux in liquid rocket combustion chambers. In previous work, we have demonstrated the capability to measure the local temperature at the inner surface of large caliber Navy guns using sensors attached to the external gun barrel surface (2.5” from the measurement point). ...

Qynergy Corporation proposes to develop a unique power system for space targets for RADAR calibration and test of advanced discrimination technologies and concepts. There is a need for well-characterized cooperative space targets that can decrease reliance on expensive BMDS integrated flight tests. The space target system would consist of at least 2 objects: a cone of approximately 1-m diameter, ...

The demand for higher performance rocket motors at a reduced cost requires continuous improvements in understanding and controlling propellant combustion. Numerous examples are available where seemingly minor modifications and improvements to existing solid rocket systems have caused previously well performing motors to exhibit unexpected and at times near catastrophic behavior. It is far cheape ...

This Phase II STTR project will continue the research and development of a simultaneous multi-species sensor system for scramjets flight test instrumentation. The sensor system is based on modulation-frequency multiplexing to combine several laser wavelengths and using a single two-color photodiode detector to collect the laser signals along the same optical path. High-sensitivity detection of c ...

Electromagnetic propulsion using compact toroidal plasmas is ideal for high-thrust, high-Isp missions since velocities and densities are not space charge limited, the self-field structure does not suffer magnetic detachment problems and the inductive electrode-less nature has superior lifetime. This STTR builds on a long history of research by integrating an annular helicon source with a conical ...
