SIFT proposes to design and develop the Marshal system, a mixed-initiative tool for maintaining task models over the course of evolving missions. SIFT will demonstrate Marshal by developing it as a plugin for the TRACLabs PRIDE procedure authoring system. A Marshal-enabled PRIDE will learn and maintain task models so that it can improve the consistency and correctness of PRL-based procedures. Ma ...

Design, fabrication, assembly and test of the Florida Turbine Technologies, Inc. (FTT) concept for a submersible, superconducting electric boost pump during Phase II will transition the pairing of superconducting motor and high performance pump technology for use in liquid hydrogen (LH2) from TRL 3 to TRL 6. This innovative solution offers significant performance and operability benefits to futur ...

The innovation proposed here is a high-performance, high-fidelity simulation capability for simulating liquid rocket spray combustion based on a novel spray-flamelet methodology which will be integrated into Loci-STREAM which is a CFD solver developed by the proposing personnel under funding from NASA over the last several years. A new spray-flamelet formulation will be incorporated into Loci-STRE ...

Architecture Framework for Fault Management Assessment And Design(AFFMAD) provides Fault Management (FM) trade space exploration and rigorous performance constraint checking for FM strategies of complex cyber-physical systems. AFFMAD will assist early evaluation of FM strategies and improve the efficiency of implementing and testing those strategies much earlier in the design process than today. W ...

The innovations proposed here are Ka-band (38 GHz) group III-nitride power FETs and the dislocation density reducing epitaxial growth methods (LPE) needed for their optimal performance and reliability.Ka-band power transistors with>60% Power Added Efficiency (PAE) are not commercially available. The primary limitations to their manufacture are lack of mature process technology at major GaN foundri ...

Advanced Materials Technology, Inc (AMTI) responds to the NASA SBIR solicitation X8 "Space Cryogenic Systems" under subtopic X8.01, "Cryogenic Fluid Transfer and Handling". The proposed Phase II SBIR program is aimed at developing new cryogenic insulations for passive thermal control, resulting in zero boil-off storage of cryogens. The passive thermal control will serve to limit the heat leak in ...

The main goal of the project is to demonstrate the feasibility of a monolithic solid state laser on the basis of PTR glass co-doped with luminescent rare earth ions. The main feature of this new complex material is its ability to be simultaneously an active laser medium and a phase photosensitive medium. That way the same piece of material can be used as laser gain element and a monolithic laser r ...

FTT proposes development of a magnetically actuated dynamic seal. Dynamic seals are used throughout the turbopump in high-performance, pump-fed, liquid rocket engines for a variety of purposes. The most common applications are in the lift-off seal (LOS), inter-propellant seal (IPS), and balance piston seals?high-pressure orifice (HPO), low-pressure orifice (LPO), and inner diameter impeller shro ...

Firefly, in collaboration with Rochester Institute of Technology, proposes developing a space solar cell having record efficiency exceeding 40% (AM0) by the introduction of nanowires within the active region of the current limiting sub-cell. The introduction of these nanoscale features will enable realization of an intermediate band solar cell (IBSC), while simultaneously increasing the effective ...

Silicon carbide (SiC) and other wide band-gap semiconductors offer great promise of high power rating, high operating temperature, simple thermal management, and ultra-high power density for both space and commercial power electronic systems. However, this great potential is seriously limited by the lack of reliable high temperature device packaging technology. The objective of this proposed resea ...
