Individual differences in vulnerability to sleep loss and fatigue from extended work hours and night work are a substantial problem in transportation policy making, work schedule development, fatigue risk management strategies, and prediction of performance impairment in real-world operations (Van Dongen et al. 2003; Mollicone et al. 2010). Our group was the first to document the considerable magn ...

ABSTRACT: The challenges in the operations of small unmanned aircraft systems (SUAS) and micro air vehicles (MAVs) in terms of required agility and benign flying qualities require a superior understanding of their basic flight mechanics and vehicle dynamics. Flight test data for MAVs are sparse, and wind tunnel unsteady aerodynamic data of MAVs with flexible wing structures are non-existent. Alth ...

ABSTRACT: TRS Technologies, Inc. proposes to develop nonlinear dielectric ceramic capacitors for discharge pulse power application and reduce the production cost of cofired multilayer capacitors. In the phase I program TRS developed a new antiferroelectric composition showing energy density>4J/cc at a field as low as 200kV/cm and demonstrated that high breakdown strength can be achieved from ant ...

ABSTRACT: The proposed program will provide three important products to the space electronics community: [A] An extremely rad-hard (estimated>3Mrad) high isolation and processor-free converter that can provide an (unregulated) intermediary voltage that can supply 6V/20V at 25W/40W respectively. [B] An extremely rad hard high isolation and processor-free converter that can provide an unregulated ...

ABSTRACT: Development of an operational prototype Test Data Aggregation and Analytical System (TDAAS) at Arnold Engineering Development Center (AEDC). TDAAS will address the customer"s need for data integration and knowledge discovery of Department of Defense (DoD) weapons system engine and flight test data at AEDC. The desired end-state for this project will be TRL 7 at AEDC providing test perso ...

ABSTRACT: An exhaust plume is a primary observable to warning sensors designed to protect low flying aircraft from MANPADS and other hostile threats such as RPG's and small arms fire with tracers. The design of current and future warning sensors and countermeasures need a complete characterization of this observable. This effort is designed to transition image morphing technology, tailored ...

Advanced Cooling Technologies, Inc. (ACT) will develop a Fast Thermal Response Fabric Test Setup for various thermal hazard scenarios involving convection (hot gas impingement by the jet engine exhaust), radiation (fire) and combination of convection and radiation (post-crash fire of aircraft, fire flash or bomb blast). The fabric test setup will (i) measure the thermal response of various clothin ...

TRS is pleased to propose an in-situ NDE imaging tool for SiC mirror surface damage (SD), sub-surface damage (SSD) and trapped internal stress detection using piezo-composite based micromachined ultrasound transducer (PCMUT) phased array technology. PCMUT technology has been developed at TRS to fabricate high frequency ultrasound transducers with broad bandwidth and high sensitivity. Phased array ...

Cultural skills are increasingly important for military actions recently undertaken by the U.S., where close continuous contact with the indigenous population is necessary. All ground forces being deployed in culturally distinct and sensitive areas need to have at least some basics skills, knowledge, and awareness of cultural norms and prohibitions. Passive learning via lectures, tutorials, vide ...

The F-22A main weapons bay experiences severe acoustic loading when exposed to the freestream. The severity and attenuation of this loading is exacerbated by the flight envelope of the F-22A aircraft, as well as the requirement to carry and release “smart” weapons throughout this envelope. This extremely harsh environment can also impact components that are mounted within the bay itself, inclu ...
