Leveraging their prior experience working with automated fiber placement (AFP) of thin-ply composite materials, NextGen Materials & Processing LLC and the University of Massachusetts Lowell will utilize a Design of Experiments approach, combined with analytical modeling, to identify the critical material, slitting, spooling, and AFP parameters that influence the repeatable, high quality laydow ...

The proposed  Bifunctional Regenerative Electrochemical Air Transformation for Human Environments (BREATHE) for life support and habitation is part of the atmosphere revitalization equipment necessary to provide and maintain a livable environment within the pressurized cabin of crewed spacecraft. Sustainable Innovations (SI) has developed a novel solid state technology for gas compression bas ...

All rocket missions benefit from having lower structural mass and higher specific impulse, both of which contribute to larger payload fractions and therefore lower mission cost. High temperature materials such as ceramic matrix composites (CMCs) are an avenue to lower engine mass because of the low density and high specific strength of the material. They also have a high maximum temperature and so ...

The objective of this proposal is the development and demonstration of a cost-effective high-fidelity aeroacoustic design tool for future commercial supersonic nozzle designs and installations. Although eddy-resolving  CFD methods for computing high-speed jet noise are available, such methods are computationally expensive and are currently deemed impractical for use in a design optimizat ...

Through this SBIR effort, NASA is looking for innovative technology to bolster its flight research capabilities.  Particularly, NASA seeks the development of innovative measurement and data acquisition approaches.  Mide through a past RIF BAA for Navair, developed a stand-alone high performance data logger for vibration/acceleration, pressure, and temperature. The device, dubbed the Slam ...

Future hybrid aircraft, such as NASA’s N3-X plan, will require all-superconducting electric motors and generators in order to achieve power density in excess of 10 kW/kg.   Unlike the DC rotor, the stator must operate in AC mode, for example, from 0-0.5 T at 120 Hz, making it impossible to use high temperature superconducting (HTS) tapes due to their high losses in transient fields, req ...

We believe a robust approach to integrated system health management (ISHM) design is the application of redundancy. Redundancy is often thought of in terms of hardware; however, functional, analytic, and information redundancy strategies should also be considered.  Modeling sensor information is invaluable for diagnostics and critical path analysis. A total system approach is an efficient mea ...

NASA's Extravehicular Mobility Unit, or EMU, is a personal mini-spacecraft that comprises the space suit assembly and life support systems. The current EMU has a manually operated extravehicular visor assembly (EVVA) that provides protection from micrometeoroids and from solar ultraviolet and infrared radiation. For the integration of EVVA with NASA’s next generation space suits helmet b ...

In several technologies within NASA’s In Situ Resource Utilization (ISRU) systems, such as fuel cell, water electrolysis and gas/water separations etc., polymeric membranes, especially proton exchange membranes (PEM), play an important role. These membranes are generally hygroscopic, subject to swelling in the presence of humidity or water. When restrained membranes undergo a hydration/dehyd ...

During dynamic events such as launch, ascent abort, atmospheric reentry, descent, and landing, crewmembers will experience significant inertial and vibrational loading.  To this date, data has not been collected in flight.  There is particular interest in the chest, neck, and head region, which are exceptionally sensitive areas.  Quantifying the loading on the crewmembers will allow ...
