The Air Force Research Laboratory (AFRL), Military Satellite Communication (MILSATCOM), and National Aeronautics and Space Administration (NASA) have a current and future need for advanced commercially available inherently radhard primitive cell libraries to support new designs for satellites and other spacecraft. American Semiconductor Inc. proposes the use of double gated Flexfet technology for ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

Hanger bearing failures occur unexpectedly and have resulted in loss of aircraft and life in both military and civilian rotorcraft. New Health and Usage Monitoring Systems (HUMS) that are currently being demonstrated on the UH-60 include sensing capabilities that offer the potential to diagnose and predict hanger bearing problems with sufficient lead time to prevent catastrophic failure. However, ...

Modern turbine engine lifing approaches compute damage accumulation in real time based on actual usage, substantially increasing the useable life over a-priori cycle or hour limits based on assumed worst-case operating conditions. However, these new algorithms are complex, consume substantial computing resources, and generate enormous amounts of data that must be archived to allow data mining and/ ...

The latent degradation of precision control system actuators affects dynamic performance and can push the performance characteristics of the actuator out of the regime needed for stable operation of the aircraft control system. Current system-level methods are not sensitive enough to actuator degradation and have no ability to isolate the fault to a specific sub-component or provide an estimate o ...

Fault detection and isolation algorithms are often developed with data from steady-state tests, and many algorithms perform well under these controlled conditions. However, when diagnostics are used in highly dynamic environments, sensitivities to changing loads or speeds become apparent. Vibration metrics tend to be particularly susceptible to operating condition variations. This sensitivity inte ...

Grease lubricated bearings are widely used in aircraft for driveshaft support, fans, and accessories. These components are a maintenance intensive item requiring regular replenishment or replacement. In addition, occasional failures occur and have resulted in loss of aircraft. Sentient Corporation, in collaboration with SKF/MRC bearings and Sikorsky Aircraft, will study and address the dominant fa ...

This SBIR Phase I project will develop a health and motion monitoring sensor and analysis system to support the return of military personnel with prosthetic devices to active duty. DoD is allowing increasing numbers of Soldiers with prosthetics to return to active duty if they are performance capable, minimizing the loss of their valuable core expertise to the services. There are significant cha ...

Gas Metal Arc Welding (GMAW) accounts for a significant proportion of all welding performed. Due to its relatively high speeds and metal deposition rates as well as relatively low equipment and maintenance costs, it is also the most popular process for automated, and especially robotic, welding. There are, however, problems that significantly restrict its manufacturing applications. The efforts at ...

INADEQUATE STARTER FEEDS SEVERELY HOLD BACK NEW AQUACULTURE ENTERPRISES SUCH AS PRESENT ATTEMPTS TO RAISE FISHES WHOSE LARVAE DEVELOP FROM SMALL EGGS AND HAVE VERY "DIFFICULT" FOOD REQUIREMENTS. INERT LARVAL FEEDS HAVE NOT SUCCESSFULLYELIMINATED THE STRICT DEPENDENCY ON NATURAL FORAGE DURING THE CRITICAL POST-LARVAL STAGE AFTER YOLK ABSORPTION AND BEFORE THE DEVELOPMENT OF A DIGESTIVE SYSTEM WITH ...
