The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

Computational fluid dynamics (CFD) is used as an analysis tool to help the designer gain greater understanding of the fluid flow phenomena involved in the components being designed. The next step in the design process is to modify the design to improve the components performance, typically performed manually by the designer in a trial and error fashion. The innovations proposed herein will provide ...

Supercritical air at cryogenic temperature is an attractive source of breathing air because of its very high density and low pressure. However, heat leak into the cryogenic tank causes the stored air to expand and vent, thus limiting the storage life of a charged system. We propose to develop a storage system for supercritical air packs that provides cryogenic cooling that will enable long-term ...

The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) engine currently being developed at NASA Johnson is an attractive technology for minimizing transit time and crew harm during future space exploration missions. One of the critical challenges in developing a flight engine is thermal management of the high-temperature, superconducting electromagnets used to constrain and accelerate the pl ...

The goal of this proposal is to develop a new method to create Non-Rotationally Symmetric (NRS) surfaces that overcomes the limitations of the current techniques and is fast, accurate and inexpensive. Diamond turning (DT) has revolutionized the fabrication of lightweight optical surfaces for defense and science applications such as forward-looking infrared radar and infrared spectrometers. It ha ...

Lightweight, high-temperature radiators are needed for future, high-efficiency power conversion systems for Nuclear Electric Propulsion (NEP). Creare has developed flexible radiators that are extremely lightweight, stowable in small volumes, and deployable with small forces, but are limited by materials to temperatures below 350 K. These novel radiators incorporate integral micrometeorite protect ...

A need exists to develop cost effective and reliable submersible cage technology for exposed aquaculture. The team assembled as part of this SBIR incorporates JPS Industries, Great Bay Aquafarms and the University of New Hampshire. In Phase I, a design will be developed based on concepts known to work in the industry. Concepts to be investigated include a cage constructed around HDPE pipe, with ...

Current animal telemetry devices are large and heavy due to their reliance on batteris to power the electronics and radios. Because of this, many species can't be effectively studied since they can not support the device weight. The smaller size will allow animal telemetry devices to be developed for species that have not had effective monitoring devices previously. The longer duration devices wil ...

This Phase 2 project will develop and demonstrate two Small Crawler Tractor (SCT2) prototypes for wildland fire suppression and management activities. Phase 1 successfully demonstrated the feasibility of using the Phase 1 unit (SCT1) for these applications. The SCT2 will have more power, weight, traction and rollover stability to meet requirements identified in Phase 1. However, it will be small a ...
