This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed. Process optimizations will be conducte ...

A bidirectional dual active bridge (DAB) dc-dc converter for electrical power systems (EPS) is proposed. The converter operates as a charger, upconverter, and downconverter using a single transformer. The converter uses smart technology to interleave DAB converter stages for ripple current reduction and optimized load sharing of stages to extend the high efficiency load range of the converter to 6 ...

CCT has designed and prototyped, as part of the Phase-1 SBIR, a generic platform independent software capability for exchange of semantic control and monitoring information. In addition, CCT has laid the foundation for auto-generation of semantic construction and interpretation libraries from semantic databases that can be used for message-based communications between loosely coupled systems. This ...

Our innovation is a high-speed method for the prediction of aerodynamic debris fields that employs an extensive database of generalized empirical equations coupled with interpolation and localization techniques. An essential element of our innovation is the vehicle independence of the equations database which allows it to be generated once and applied to any vehicle. The large-scale operation of ...

Phase I demonstrated experimentally a very high temperature acoustically absorbing coating for ducted acoustics applications. High temperature survivability at 3500 deg F was demonstrated in the MSFC Plasma Jet Facility. Normal incidence acoustic absorption coefficient of 25 % was demonstrated in a standing wave test facility. Phase I work confirmed the possibility of production of acoustic coatin ...

This proposal describes the continued development of passive, orthogonal frequency coded (OFC) surface acoustic wave (SAW) sensors and multi-sensor systems, an enabling technology for remote wireless sensing of temperature, pressure, and a range of other measurands, for application to space explorations' demanding environments. Phase I demonstrated the technical feasibility of the OFC approach to ...

Development of a fully functional Multimedia Literacy Software (MLSW) progam to address the needs of deaf/hard of hearing and other students and identify best uses of the MLSW in instruction of reading skills

Extra-vehicular activities (EVA) on the Moon and Mars will require suits with sophisticated thermal control systems allowing astronauts to work for extended periods of time. Use of consumables such as water that cannot be easily replaced should be of particular concern. In this aspect the EVA suits for Moon/Mars environments need to be different from the current Space Shuttle Extra Vehicular Mobil ...

Loci-STREAM is a CFD-based, multidisciplinary, high-fidelity design and analysis tool resulting from Phase I work whose objectives were: (a) to demonstrate the feasibility of implementing a reacting-flow pressure-based algorithm in the Loci framework, and (b) to test the robustness of a real-fluid methodology in the pressure-based framework. Loci is a rule-based programming framework which automa ...
