A modern gas turbine engine such as the T800-LHT-800, which is to be used in the Army's Light Helicopter Experimental (LHX) Helicopter (now referred to as the RAH-66 Comanche), is among the most complex mechanical systems in use today. The parameters involved in diagnosing a fault are numerous and often subtly interrelated. The objective of Phase I is to define a system architecture for a diagnost ...

The objective of this effort is to demonstrate a prototype advanced diagnostic system for the T800 turboshaft engine using a hybrid polynomial network and production-rule expert system. The resulting system will demonstrate the feasibility of developing a revolutionary diagnostic capability which can model the engine at a system level, detect failures before they become signficant isolate faults, ...

Coherent Technologies, Inc. (CTI) proposes to develop an eyesafe Multiple Intgegrated Laser Engagement System (MILES) laser transponder for use in Tactical Engagement Simulations (TES). The new MILES transponder will provide for eyesore operation while 1) enhancing the laser engagement range, 2) reducing the probability of false alarms and missed hits, and 3) providing superior penetration throug ...

Advanced turbine engines and flight vehicles will depend upon new, high-temperature metal matrix composites (MMC's) to meet performance goals. Engineering characterization of such materials is difficult and costly, which accounts for the meager property database available to designers. Thin-walled tubes would be especially useful for developing constitutive relations and failure criteria under mul ...

IA, Inc. proposes to develop a light weight, field-portable, fiber-optic sensor capable of measuring a panel of prognostic and diagnostic infection indicators including IL-6, TNF-alpha, IL-12, and CRP. The proposed sensor will provide a system suitable for field medical units which is capable of early detection of infection, and will require only minimally trained operators. The sensor will be a ...

Future battlefields will require independent operations and increased operational tempo, placing severe burdens on weapons platform crewmembers in the areas of information flow management, data fusion, and assessment of data to arrive at the most tactically acceptable decisions. Work continues in the development of decision aids to assist direct/indirect fire weapon platform commanders in accompl ...

There are currently no fire warning systems in use at ammunition storage areas. This is due to the lack of a detection and warning system that is capable of operation in large areas where there are multiple background sources. Early detection and suppression of fires in hazardous areas can save lives as well as millions of dollars in lost weapons and ammunition. We propose a fire-detection and ...

Elastomeric O-rings provide a critical sealing funcion in a myriad of devices of military and commerical interest. A critical problem with currently available O-rings occurs when the O-ring material stiffens at low temperatures, causing a failure in sealing. Previous work by the Army has indicated that a fluid filled O-ring is a viable candidate as a low temperature seal. There is a need to extend ...
