ORBITEC proposes to continue the development of high-performance fuels to replace monomethyl hydrazine (MMH) and other storable fuels for in-space propulsion applications. Compounds from various chemical families were proposed in Phase I to address these needs. These families of compounds have greater heats of formation, lower volatility, and lower toxicity than MMH. Their reduced vapor pressur ...

The proposed study aims at accelerated development of Mo-Si-B-X (X=Ti, Zr, Hf, Re, Mn) alloys with an optimized balance of properties, via an approach of integrating thermodynamic modeling with experimental study.   On the basis of the Mo-Si-B-X (X=Ti, Zr, Hf) database developed in Phase I, a thermodynamic database of the Mo-Si-B-O-X (X=Ti, Zr, Hf, Re, Mn) system will be developed using the Calp ...

An innovative data collection and analysis approach is proposed to enable body mount magnetometers for space application. In order to achieve high accurate magnetic field measurement in space, the magnetometer has to be located in a âmagnetically cleanâ place, where the magnetic field from spacecraft is negligible. Usually, the magnetometers are placed on deployable booms, so that the field sens ...

Orbital Technologies Corporation (ORBITEC) proposes to develop a monopropellant Self-Pressurizing Gas Generator (SPGG) warm gas pressurization system for satellite propulsion system applications.  The SPGG system will utilize a novel method to pressurize the propellant.  The proposed system offers significant advantages over the traditional helium gas pressurization system.  The SPGG will provi ...

ORBITEC proposes to demonstrate and validate a laboratory scale experimental injector stability screening technique which will quantify injector element stability characteristics.  The experimental approach promises to dramatically reduce development cost by utilizing a gaseous single element test facility which presents savings in hardware manufacturing, consumables such as propellant and test p ...

The goal of this SBIR is the enhancement of the current state-of-the-art combustion instability analysis tools.  The planned enhancement is focused on capturing the effects of injection element distribution and the inclusion of substantial film cooling and diluent injection.  These characteristics are extremely important in the design of high-pressure oxygen rich staged combustion (ORSC) engines ...

The major requirements for this program include the modeling of optical switching fabric technologies appropriate to space-borne systems at very high speed. Specifically, this program will evaluate two OptiComp candidate optical transceiver technologies against a Serial Rapid IO switching fabric. A down-selection to one optical transceiver technology will be made. Then, a simulation of that Serial ...

The major requirements for this program include the modeling of optical routing technologies appropriate to space-borne systems at very high speed. This program will investigate optical routing at speeds to from 3.125 ro 10 Gbps per channel, with a wavelength/channel density from 4 to 16 wavelengths. Models will be constructed for these regimes, and an experimental demonstration of an 8-wavelength ...

The European Union''s RoHS and WEE Directives mandated the elimination of the carcinogenic, hexavalent chromium coatings for metals, including magnesium and zinc-nickel plated substrates.  The purpose of this project is to find chemistry that will meet requirements of industry performance specifications and of the mandate.  METALAST intends to explore trivalent chromium in conjunction with two o ...

ORBITEC proposes to develop a heat transfer model to predict heat transfer coefficient in bubbly flows in small tubes.  This model is intended for application to thermal management systems in a variety of propulsion systems, including both air-breathing and rocket engines.  The Phase I work will include parallel experimental and modeling work.  The experimental program will measure heat transfe ...
