Large space-deployed structures such as synthetic aperture radars, radiometers, and solar arrays are receiving a great deal of interest by NASA in the Earth Sciences program. These large structures by necessity must be ultra-lightweight and low stored volume. Inflatable or self-deployable approaches that become rigid after they reach the correct shape appear to be a promising approach for fabricat ...

There is an increasing need for large, reliable, and cost-effective inflatable space antennas for communications applications. This Phase I program will focus on the design and development of open-celled foams as structural elements in self-deploying antenna systems. Foams offer the following significant advantages over conventional materials for these applications: open cellular structure allowin ...

Performance requirements for polymer matrix composites (PMCs) in aerospace and transportation applications are generally quite stringent. Among these requirements are excellent thermal stability, high strength and high toughness. Easy processing is also desirable. Electron-beam (e-beam) curing has the potential to significantly reduce the overall cost of manufacturing PMC parts for use in aerospac ...

Next generation design software will support fully associative geometric and physics-based analysis models throughout the entire product life-cycle. Most current CAD systems directly support finite element systems, but use proprietary database formats that do not promote diverse tool use and may not exist throughout the entire product life-cycle. Model sharing in common practice has been limited t ...

Platforms for scientific instruments increasingly require attitude knowledge and optical instrument pointing at sub-arcsecond accuracy. No low-cost commercial system exists to provide this level of accuracy for guidance, navigation, and control (GNC) and precision instrument pointing. ATA proposes to introduce a small inexpensive inertial attitude reference system based upon magnetohydrodynamic (M ...

The proposed SBIR Phase II effort to develop a Personal Health and Fitness Wizard (PHFW) will, within the first year, year a fully functional Internet-based site the provides individual users with easily accessible, tailored guidance concerning theirpersonal health and fitness. The PHFW will to beyond simply providing health and fitness advice: it will function as a

The flight envelope for X-34 ranges from subsonic to hypersonic with altitudes up to 50 miles. Designing a guidance law that performs across this broad flight envelope presents several challenges. Robustness to uncertain aerodynamics is of paramount importance because of the sparse amount of wind tunnel and flight test data that exists for reusable launch vehicles at hypersonic Mach numbers. The n ...

NASA has identified a need to reduce weight and cost of cooled composite nozzle ramps. A lightweight actively cooled ceramic matrix composite (CMC) system would be lighter than metallic designs and would require significantly less cooling during re-entry. Composite Factory proposes a zirconium-silicate or Zr-Si-O glass CMC with integral ceramic tubes reinforced with a low cost discontinuous cerami ...
