SBC: Gordon Nelson and Associates Topic: T703
Project involves development of new flexible FR polyurethane (PU)insulation foams through a non-toxic environmentally friendly composite approach. Foams have bound-in polymeric phosphonate FRs, with added synergists and smoke suppressants. Such foams will not leach FR. Foams have fine cell structure and excellent flexible foam properties. Cone performance of the identified foam family (368 peak ...STTR Phase II 2013 National Aeronautics and Space Administration
SBC: AURORA FLIGHT SCIENCES CORPORATION Topic: T101
Space policy direction is shifting, particularly with respect to human goals. Given the uncertainty of future missions to the moon, Mars, and other bodies, a tool that allows for informed analysis of the option space is particularly relevant. Aurora Flight Sciences and MIT propose to further develop the Multi-Robot Planetary Exploration Architecture (MRPEA) methodology, a suite of software tools ...STTR Phase II 2010 National Aeronautics and Space Administration
SBC: CFD RESEARCH CORPORATION Topic: T102
Solid rocket motor (SRM) design requires thorough understanding of the slag accumulation process in order to: predict thrust continuity, optimize propellant conversion efficiency, predict coning effects from sloshing, and assess potential orbital debris (slag) hazard. Current state-of-the-art models for SRM environment do not have the capability to simulate the accumulation and dynamics of slag in ...STTR Phase I 2017 National Aeronautics and Space Administration
SBC: Prime Photonics, LC Topic: T1201
Prime Photonics proposes to team with Dr. Duke of Virginia Tech to develop a multi-mode, enhanced piezoelectric acoustic emission sensing system to couple large damage events to local distribution of damage accommodation. Our system will be centered around an instrument designed to accept the output of a piezoelectric transducer sensitive to in-plane acoustic events. The signal processing path w ...STTR Phase II 2016 National Aeronautics and Space Administration
SBC: Sentix Topic: T1502
Sentix and Brigham Young University propose the research and development of embedded payload intelligence for inflight optimization of surveillance, reconnaissance, and scientific missions. The current proposal leverages a substantial body of scientific and experimental knowledge derived from the Tactical Seeability System developed by Sentix' staff and BYU researchers to provide fully automated ...STTR Phase I 2013 National Aeronautics and Space Administration
SBC: Plasma Processes, LLC Topic: T301
Small and micro-spacecrafts require the efficient, micro-propulsion systems. Chemical micro-propulsion is best suited for use as primary thrust, orbital insertion and attitude control because of its high energy density. When grouped into arrays for larger thrust applications, micro-propulsion devices provide high propulsive flexibility or can be used as igniters. The proposed effort will focus ...STTR Phase I 2010 National Aeronautics and Space Administration
Metal Digital Direct Manufacturing (MDDM) for Close-Out of Combustion Chambers and Nozzle FabricationsSBC: Keystone Synergistic Enterprises, LLC Topic: T1204
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 ...STTR Phase II 2017 National Aeronautics and Space Administration
SBC: Research South, Inc. Topic: T801
This proposal offers to provide NASA with an automatic mesh generator for the simulation of aerodynamic flows using Reynolds-Averages Navier-Stokes (RANS) models. The tools will be capable of generating high-quality, highly-stretched (anisotropic) grids in boundary layer regions and transition smoothly to inviscid flow regions even in an adaptive context. The objective of the work is to offer a un ...STTR Phase I 2010 National Aeronautics and Space Administration
MEMS Based Solutions for an Integrated and Miniaturized Multi-Spectrum Energy Harvesting and Conservation SystemSBC: Radiance Technologies, Inc. Topic: T301
The objective of this proposal is to develop three unique energy harvesting technologies utilizing our existing research strengths that will be of interest and utility to NASA applications and environmental conditions. By developing multiple technologies, NASA will be able to harvest energy from multiple waste energy sources, namely environmental vibrations, thermal energy, and solar flux. These d ...STTR Phase I 2013 National Aeronautics and Space Administration
SBC: EMBEDDED DYNAMICS LLC Topic: T1501
The tiltwing class of aircraft consists of vehicles with the ability to rotate the wing and propulsion system as a unit a full 90 degrees from the standard fixed wing configuration to one in which the wing and thrust axis become perpendicular to the body axis. This thrust vectoring capability allows the aircraft to utilize thrust borne flight for vertical takeoff and landing as well as the convent ...STTR Phase I 2017 National Aeronautics and Space Administration
