This proposal comprises research efforts to study a dynamic non-stationary friction regime with a variable range of external factors or parameters. This research method considers the development of special non-linear mathematical models for enginetribology including the lubricating oil film thickness as a function of a series of independent parameters in extreme working conditions. These modelin ...

The Future Combat System (FCS) military diesel engine propulsion systems tribological considerations are predicted to be compromised primarily by the temperature capability of the lubricating fluid. Thermal oxidation resulting in lubricant work in rigidcondition breakdown and formation of deposits are typical causes of engine failure at high temperature operating conditions. Work in the Phase I ...

AEgis Technologies Group, Inc. is pleased to present this proposal for a Phase II SBIR entitled,

This Research and Development (R&D) effort will produce an architecture and prototype for performing quick-look analysis of Electromagnetic (EM) Compatibility (EMC) using Modeling and Simulation (M&S) technologies. The target domain will be aircraftsustainment and will focus on the insertion of commercial-off-the-shelf (COTS) technologies into existing aircraft. COTS technologies provide a cost- ...

The thermal protection system (TPS) community is in critical need of a newdesign paradigm if the vision of low maintenance, high sortie rate spacevehicles is to be realized. A revolutionary change is needed in the TPSdesign approach and in the use of innovative materials that can survive longdurations in an extreme heating environment without significant ablation.Low erosion, low conductivity mat ...

A MEMS Rotating Annular Sensor (MARS) is proposed which senses rotation velocities and accelerations in one discrete time sensor. Differential capacitance measured at various points about the annulus permit a single MARS to measure accelerations in threedegrees of freedom and rotational velocities in two, missing only the angular velocity about the local z axis. Two MARS systems can be used for fu ...

Archangel's Air Data Attitude Heading Reference System (ADAHRS) is a solid-state unit that integrates low-cost piezoelectric MEMS gyros and accelerometers, as well as pitot and static sensing devices and a magnetometer with a local processor. Accuraciesto 1 degree RMS have been demonstrated in aircraft test flights. Long term stability of the ADAHRS has been demonstrated to be better than 1 degre ...

Given two closely related pieces of software X and Y, where Y differs from X through a number of small but important (from a security point of view) modifications that were done to Y, the

Early and effective hemodialysis can decrease mortality of trauma patients with acute renal failure. Unfortunately, current technology is not easily deployed in the field or during transport of patients. The Sorbent Hemodialysis (SHD) System now beingdeveloped using technology from Ash Medical utilizes the SORB cartridge to produce and regenerate a small dialysate volume (6 liters). The SHD improv ...
