Environmental control and life support (ECLS) within closed environments must remove humidity from the air both to maintain crew comfort and to recycle potable water. The current state-of-the-art technology recovers water vapor by cooling air to below its dew point in a condensing heat exchanger. This requires chilled water at about 5 C as the cooling sink. However, desiccants can be used to recov ...

There currently is no commercially available instrument which can be programmed and used in real time to analyze a variety of electroactive species in the marine environment and simultaneously record pH and temperature. The development of a deployable / profiling electrochemical platform would allow for the real time measurement of electroactive species, pH and temperature in the water column, sed ...

The electrostatic atomization of hydrocarbon fuels provides precise, predictable electronic control of droplet size and distribution independent of fuel viscosity, density and flow rate. Phase I will focus on demonstrating that electrostatic fuel preparation makes combustion performance in an ambient combustion environment insensitive to the presence of anti-misting fuel additive (FM-9). A hybrid ...

The development of new, active flow control devices will be critical to meeting the NASA Aerospace Technology Enterprise goals of reducing air travel costs by 25% in 10 years and 50% in 25 years. Continuum Dynamics, Inc. (CDI) proposes the development of a new ¿pop-up¿ vortex generator (PUVG) concept which will eliminate cruise and off-design drag penalties of conventional vortex generators thro ...

Recent developments have illustrated the tremendous potential of very small-scale rotorcraft (Micro Rotorcraft or MRCs) for entirely new missions such as remote sensing, surveillance, and autonomous exploration. Vehicle design at this scale is constrained by performance limitations inherent in operating at low Reynolds number. This effort will exploit new, lightweight Shape Memory Alloy (SMA) actu ...

We propose to develop and demonstrate new ablation/erosion resistant carbon material for application in nanosatellite propulsion systems. Our newly invented conductive superhard, high bond strength ¿polymerized¿ fullerene materials will achieve the high ablation and erosion resistance. The new materials called Fullertubite and DiamoniteTM (patent pending) have properties that make them ideal for ...

For many ultraviolet applications, beta-barium borate (BBO) is the material of choice for harmonic generation due to the outstanding nonlinear properties, ultraviolet transparency, and mechanical robustness of the single crystals. Despite these attractive features, issues that limit the usefulness of BBO for ultraviolet generation include heating, due to Intensity Dependent Loss (IDL) and surface ...

Dynamically certified seats (16g seats) are being fielded in all jet transports certified since 1988. In addition, the airlines are steadily replacing their older seats with 16g compatible seats in the older aircraft certified prior to that date. The implementation of the dynamic seat requirements has encountered one unanticipated problem. Under normal use, seat cushions must be replaced with iden ...
