Thermal batteries are primary batteries ideally suited for military ordnance, projectiles, mines, decoys, torpedoes, and space exploration systems where they are used as highly reliable energy source with high power density and extremely long shelf life. Thermal batteries are manufactured using techniques that place inherent limits on the minimum thickness obtainable while ensuring adequate mechan ...

Thermal sensors are an enabling technology for a wide range of consumer goods, industrial operations, and military equipment. State-of-the-art thermal sensor technology has several inherent technology barriers which preclude the availability of cost-effective thermal sensors for applications that require linear circuit output, thermal stability, ppm level performance reproducibility, low device we ...

Optomec Design Company proposes to use Laser Engineered Net Shaping (LENSTM), a Rapid Prototyping and Manufacturing (RP&M) technology currently under development at Sandia National Laboratories (SNL), as a new method for integrating instrumentation (e.g., embedded sensors) into metal structural components. SNL has demonstrated the ability of the LENSTM technology to produce near net shape stainles ...

For motor, generator, transformer, and transmission line applications, demonstration projects have been conducted using Bi:2223 high temperature superconductors. There is the desire to use these conductors in AC applications at temperatures from 20-77K. Currently these conductors use silver or high silver alloys for their sheath material, this high silver content and the bridging of filaments re ...

A low cost hollow cathode is proposed for use with various xenon based electric propulsion systems. In addition to a factor of five reduction in cost the proposed device would offer several advantages over the current NASA developed state-of-art hollow cathode. These advantages include a reduction in the susceptibility to damage through launch vibrations, the replacement of the life limiting swage ...

Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

This proposal addresses the exploratory development and evaluation of novel thin film and/or monolithic detonators as diverters for guided spinning projectile use. A number of such detonators comprise a diverter technology termed RMDM, (for Ring Matrix Diverter Module) which, along with the SSPG (for Small Spinning Projectile Guidance) seeker, forms the basis for inexpensive miniature guided proje ...

BMDO seeks development of novel methods to cut tabrication cost of metallic spacecraft and interceptor structures. UTRON proposes to develop an innovative rapid powder consolidation technique called Combustion Driven Dynamic Consolidation (CDDC) to consolidate metal (and other) powders. This technique is versatile and can be applied to various material systems such as metal and alloy powders, inte ...
