This project proposes to study the core concepts of Active Conceptual modeling (A-CM) with applications to military and commercial systems. We plan to explore the feasibility of extending the mathematical framework for Entity-Relationship (ER)-based active conceptual modeling developed by Dr. Peter Chen to represent scenario snapshots that include time, space, uncertainty, and perspective dimensio ...

Active force-feedback control inceptors are gaining acceptance for potential future use in new and retrofit Army helicopter programs. Current active inceptor types use electric motors, gearboxes and linkages in a closed loop servo system to provide the necessary feel quality and functionality. These units successfully meet the performance requirements, but are expensive and mechanically complex. ...

The prospect of using smart material technology for active inceptor motion systems is of high interest because of the potential cost, simplicity and performance advantages over current brushless DC motor/gearbox systems. The most suitable smart material concept for accurate motion control is piezoelectric actuation, because of its precise controllability, force and bandwidth capability. Phase I ...

The primary technical objective of the proposed effort will be to investigate integration of optical gain medium with thin-film lithium niobate on insulator (TFLNOI) optical waveguides. Recent developments in crystal ion-sliced (CIS) TFLNOI have enabled a new class of electro-optic modulators and photonic integrated circuits with tighter mode confinement, a compact footprint, ultra-high bandwidth, ...

Active clearance control promises considerable improvements in rotating component efficiencies and compressor surge margin. These improvements are essential to meet stringent performance requirements for next generation propulsion systems. The improvements are more pronounced for small engines, because clearance effect in small engines accounts for a bigger portion of rotating component losses tha ...

This Small Business Innovation Research Phase I project, will investigate manufacturing of shims and cold plates from ultra high thermal conductivity composites for thermal management of wide band gap active component in T/R modules for S-band and X-band radar. This materials based design approach will utilize ultra high conductivity Diamond/Aluminum and Diamond/Copper materials made by MER. To pr ...

The global war on terror has dramatically changed the environment in which today's warfighter operates. Many of the locations in theater require moving troops and equipment into areas with unimproved landing zones. Loss of situational awareness in degraded visual environments is one of the largest threats to rotary wing aircraft operating in these areas. Phase Sensitive Innovations has built a pas ...

Control systems that stabilize the operation of a compressor around the surge line have been demonstrated in controlled laboratory conditions on fixed speed compressors. Jet engine manufacturers are considering this technology for improving engine performance and operability by reducing the compressor surge margins that are currently built into engine control logic. To demonstrate this technolog ...

ADVANCED AEROSPACE PROGRAMS REQUIRE MATERIALS CAPABLE OF OPERATING IN TEMPERATURE ENVIRONMENTS EXCEEDING 2000OF. TO ASSESS THE THERMAL AND STRUCTURAL PERFORMANCE OF THESE MATERIALS, TESTING MUST BE PERFORMED AT HIGH TEMPERATURES. NEW TECHNIQUES ARE NEEDED TO MONITOR AND ASSESS MATERIAL PERFORMANCE UNDER THESE TEST CONDITIONS. PROPOSED IS THE DEVELOPMENT OF AN IMAGING SYSTEM FOR MONITORING THERMO-S ...
