A fiber optic grating structural integrity measurement system is proposed. It has a sensor suite that combines multi-parameter fiber grating strain, temperature, humidity/moisture and UV sensors. These Blue Road Research embedded fiber grating sensors will be monitored in test composite coupons and their output linked to composite models developed by the University of Delaware so that the struct ...

Insensitive munitions (IM) design and testing for propulsion systems is hindered both by high test costs and the complexity of propellant responses to IM stimuli. Modeling and simulation tools for predictions of IM hazards are under development that characterize many of the pertinent phenomena, including damage sensitization to reaction and delayed-onset detonation. Such tools can provide many b ...

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 ...

Hood Technology, along with its partner Williams International, propose to develop, test and supply a Non-Intrusive Stress Measurement System (NSMS) designed specifically for small turboshaft engines. This system will address the issues of these small engines at the sensor, acquisition and software levels, providing a non-proprietary, commercial-based NSMS system tailored for this class of powerp ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

Maintenance on Army Tactical Power Systems (TPS's) is currently performed at regular intervals regardless of actual usage or operating conditions - wasting resources servicing systems that do not need maintenance, and missing opportunities to prevent catastrophic failures. The Army seeks to 1) improve maintenance efficiency and effectiveness by servicing systems based on actual usage and 2) imple ...

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 ...

Infection in areas of bone injury are a serious consideration in the field of trauma surgery and orthopaedic medicine. The combination of regenerative medicine and controlled drug delivery offers great potential to improve on the current standard of care. Presently, bone infection secondary to osteomyelitis and non-union are treated in a two-stage protocol wherein the first step requires placeme ...

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, ...
