Silicon carbide (SiC)semiconductors offer revolutionary improvements in power electronics due to much lower conduction and switching losses, higher switching frequencies, higher voltage capability, higher operating temperatures and other superior properties relative to standard silicon. Losses in a converter will be decreased by a factor of ten, frequency will be increased by a factor of ten and ...

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, ...

ENHANCED GUN TUBES AND PROPELLANT TECHNOLOGY HAVE GREATLY INCREASED PROJECTILE VELOCITIES, DYNAMIC FORCES, AND AERODYNAMIC HEATING OF TANK-LAUNCHED PROJECTILES. IN MANY INSTANCES THE STRENGTH AND TEMPERATURE LIMIATIONS OF ALUMINUM ALLOY FINS HAVE BEEN EXCEEDED UNDER TANK GUN IN-BORE PROJECTION AND IN-FLIGHT CONDITIONS AND HAVE RESULTED IN DEGRADED OR COMPROMISED WEAPON SYSTEM PERFORMANCE. NEW EROS ...

In response to SBIR topic A05-236, a proposal based on a novel concept in MOSFET design and fabrication is proposed to address the problems of (i) low channel mobility, (iii) low and unstable threshold voltage, and (iii) low gate oxide reliability under both high electric field and high temperature. Phase I will be focused on feasibility demonstration. A physics-based device model will be develope ...

A critical operational problem for current Army rotorcraft is the prediction of landing conditions in a sand/dust/snow laden environment where rotorwash picks up loose ground cover leading to a condition of obscured visibility known as "brownout". The proposed effort will develop both a comprehensive analysis and flight simulation tool able to predict the magnitude and distribution of visibility ...

The proposed effort will focus on the disruption of networks versus particular communications links using powerful optimization and co-design approaches. A technique for assigning target value metrics will be developed an applied to `best effort' extractions of adversary network topologies proposed in this work. Adversary network usage denial is conducted in conjunction with goals that reflect min ...

CURRENT FUZES FOR CARGO DISPENSING PROJECTILES CAN ALSO BE FITTED WITH A HIGH EXPLOSIVE (HE) BOOSTER PELLET AND USED TO INITIATE HE BURSTER TYPE PROJECTILES. ITI PROPOSES TO DEVELOP A SHAPE CHARGE FUZE THAT WILL DETONATE BOTH PROJECTILES. THE PHASE I EFFORT WILL INCLUDE ANALYSIS OF THE EXISTING PROJECTILE CONFIGURATIONS AND EXPLOSIVE/PROPELLANT CONTENT, SELECTION OF A SUITABLE SHAPE CHARGE CONFIGU ...

The integration of NIRS measures with EEG could be a significant advance in rapid detection and continuous monitoring of cerebral dysfunction following traumatic brain injury. We have developed a dense array EEG system that can be applied rapidly in the field environment. We have developed a prototype NIRS brain imaging system that can be integrated with the EEG system, in both sparse and dense ar ...
