The overall technical objective of the proposed Phase II program is to complete a system-level demonstration to show the capability and benefits of integrating this backup radiator/Variable Conductance Heat Pipe (VCHP) with the Advanced Stirling Radioisotope Generator (ASRG). The Phase I project developed a feasible VCHP radiator design that can be integrated with the ASRG. In Phase II, a trade ...

The Phase I project successfully demonstrated the feasibility of the vapor compression hybrid two-phase loop (VCHTPL). The test results showed the high temperature-lift capability and robust operation under transient heat loads of the VCHTPL. At the end of Phase I, the VCHTPL technology reached the NASA's defined Technology Readiness Level (TRL) 4 (Component/breadboard validation in a laboratory e ...

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 ...

The principal Phase II objective is to refine and further develop the prototype PCHP into a useful thermal management tool. The Phase I program established the feasibility of thermal control an axially-grooved heat pipe with a variable-volume reservoir. The follow-on Phase II program will address control system optimization, component longevity, reductions in mass and power, and show that the de ...

In order to achieve high performance at acceptable cost, PEM fuel cells are required to work at elevated temperature and low relative humidity (near 0 RH) for extended periods of time. However, to date, no commercial PEMs or publicly reported PEMs can meet these requirements. The objectives of this work are: (1) to develop PEMs that have high proton conductivities (50-100 mS/cm) and low area-spec ...

The proposed Phase 2 project consists of the physical integration of our Phase 1 small, compact exciter with a "flight like" igniter or spark plug capable of hot-fire testing. The exciter/igniter unit will operate to a pre-established subset of expected flight performance requirements established and met in Phase 1. The exciter/igniter unit will physically integrate the exciter electronics with ...

The first critical step in welding or brazing is cleaning to remove surface contamination. The Air Force has a need for an environmentally cleaning method that has no waste stream, minimal requirements of personal safety protection, and does not impact component integrity. The Arc Scrubber is an emerging non-chemical cleaning technology that utilizes and electrical arc to remove surface contamin ...

Applied Optimization, Inc. [AO] proposes to demonstrate full feature characterization of unresolved RSOs by performing spectral unmixing and time-frequency analysis of its time and spectrally resolved signature in the visible or infrared spectrum. The characterization will be performed step-by-step by following a taxonomy of feature extraction. Materials identification will be performed via spectr ...

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 ...

TRS Technologies, Virginia Tech., and MTech, Inc. propose to develop high torque (>1.5 kg-cm), lightweight (< 250 g), low power (< 2 watts), high precision (
