Advanced Technologies Group, Inc. proposes the development of a Methane Liquid-Level Sensor, (MLS) for In-Space cryogenic storage capable of continuous monitoring of liquid quantities to better than 1% accuracy. The proposed sensor builds on previous liquid hydrogen sensor development successes and patents. It can be utilized to measure cryogenic propellants, and sub-critical cryogenic fluids in ...

Exploration of planetary surfaces will require a communication architecture that supports operational capabilities in which fixed and mobile assets on the planetary surface can communicate seamlessly and securely. Aeronix understands the issues and believes that the solution lies in the development of radiation tolerant wireless devices that employ the benefits of FPGA technology as an underlyin ...

Range surveillance is a critical component of space exploration because of its implications on safety, cost, and overall mission timeline. However, launch delays, due to the difficulty of verifying a cleared range, are common and will increase as spaceports are developed in new areas. In order to expedite range clearance, it is vital to see "through" the atmosphere. Unfortunately, the quality ...

Florida Turbine Technologies (FTT) proposes to conduct research necessary to develop a physics-based pneumatic hammer instability model for hydrostatic bearings operating in a compressible fluid. The innovation of the resulting model is to account for the extreme density, compressibility, and non-uniform pressure variations found in highly turbulent rocket engine liquid hydrogen turbopump hydrost ...

NovaSol proposes to develop an advanced hyperspectral imaging system for earth science missions named BRASS (Broadband Advanced Spectral System). BRASS combines state-of-the-art, existing NASA detector technology and proven electronics with a novel spectrometer design to provide a compact instrument that covers the full wavelength range from 0.4 to 5 ?m. Applications for such an instrument range f ...

The purpose of this NASA SBIR Phase I proposal is to develop a novel type of high resolving power diffraction gratings based on volume Bragg gratings technology. The key innovation to be used for creation of these gratings is the patented technology on production of high efficiency volume diffractive elements in photo-thermo-refractive (PTR) glass on which OptiGrate has an exclusive license from t ...

One of the most efficient ways to create narrow band filter is the use of reflective Bragg gratings or which allow increasing of efficiency and decreasing of weight compare to conventional technologies. OptiGrate have proved the concept of high efficiency narrow-band mirrors in photo-thermo-refractive glass (PTR) glass for high power laser applications based on a unique technology for phase hologr ...

There is a need for lightweight high-density (4000+ lines/mm) novel diffraction grating elements in modern telescopes to advance EUV and X-ray astrophysics. Current grating technologies (ruling and holographic beam interference) do not provide optimal solution for all grating requirements. In response to NASA request, we propose to apply state-of-the art DUV reduction photolithographic tools dev ...

Increasing thermal requirements for space-based thermal control systems are straining the capabilities of conventional heat pipes. Mainstream has experimentally demonstrated a new wick configuration that has been shown to more than triple the heat transport capacity of an otherwise identical copper water heat pipe(this proposal contains the experimental data). This Phase I will seek to extend ...

This proposal discloses an innovative, economically feasible technique to capture and re-liquefy the hydrogen boil-off by using carbon nanotube adsorption prior to liquefaction. The hydrogen boil- off involves an average of 10,300 SCFM of hydrogen vapor at pressures below 17 psia for a period of an hour. The configuration disclosed in the proposal significantly reduces the size of the liquefacti ...
