The goal of this program is to develop high-speed interceptor communications solutions that are hardened to space and nuclear radiation, including high altitude nuclear explosions (HANEs). As part of this program, AET will specifically investigate the use of advanced diamond technology for communications applications. The approach of AET, Inc. is to first identify a communication system architectu ...

Corvid Technologies is pleased to offer this proposal for the development of a first-principles numerical approach to modeling Solid Rocket Motor (SRMs) response to unplanned thermal stimuli. Corvid has a history of developing models for propellant violent reaction to projectile and fragment impact stimuli. We will adapt an existing heat transfer model to address SRM fast and slow cook-off due to ...

The overall objective of the pellet production automation program is to develop alternative methodologies for: 1) precise powder measurement, 2) powder preparation for transfer into the die cavity, 3) uniform powder dispersion. Pellet production is currently a rate limiting step in the production of thermal batteries. The chemical, physical, and mechanical properties of the powders are different e ...

Kyma Technologies will explore aspects of seeded bulk GaN crystal growth to develop manufacturing processes for large area, high quality, semi-insulating GaN substrates for RF applications. Preparation of GaN seeds and growth thereon, including surface cleaning, off-cut angle and direction, growth initiation, and defect control will be investigated. The use of novel seeds and growth conditions wil ...

Kyma Technologies proposes a research and development effort to fabricate and test GaN-based FETs on GaN and SiC substrates. AlGaN/GaN HEMT structures will be tested to identify the impact of defects on the thermal characteristics and degradation behavior in the devices in order to improve device performance and reliability. Thermal models of GaN-based FETs on GaN substrates with comparisons to Si ...

The overall objective of this Phase II effort is to implement a HVPE crystal growth tool for large diameter GaN crystals suitable for 4" diameter substrates. Using this new crystal growth platform, Kyma will optimize its design and operation to develop a manufacturing process for growing high quality, low defect density semi-insulating GaN substrates. CFD modeling will be used extensively to ident ...

The Airborne Laser (ABL) is a key component of the US government's overall ballistic missile defense systems. In an operational scenario, the ABL's sensor system will detect and track enemy's boosting missile, determine its position and destroy it with a high energy laser. The ABL's sensor system also identifies the launch location and predicts the impact location, which is communicated to other a ...

The extremely long and multiple polishing steps represent one of the critical challenges for affordable, volume production of high quality 100 mm SiC wafers. As SiC is relatively chemically inert and mechanically hard, aggressive polishing methods involving very hard particles have been used to achieve high removal rates, but such methods create a high degree of sub-surface damage and scratches. T ...

Clothing that protects Special Reaction Teams from chemical, biological, and nuclear threats can subject the individuals to heat stress. These hazardous environments require the use of PPE with level A protection for several hours, which can diminish the body’s ability to reject heat, leading to symptoms ranging from muscular weakness, dizziness and physical discomfort to more severe, life-threa ...
