Power electronic converters are essential in every MDA vehicle, with use in critical systems ranging from electric power management applications, to power distribution, to on-board servo motor/actuator drivers. Advancing state-of-the-art power electronics technologies through the use of SiC semiconductors will produce significant savings across the board in almost all areas of MDA power management ...

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 ...

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 most significant hardware costs on a missile interceptor propulsion system are associated with the thrusters, for which there are typically four divert thrusters and four, six, or eight attitude control thrusters per interceptor. The largest contributor to the thruster cost is the integrated valve/injector. Integration of the valve and injector into a single body provides the benefits of low d ...

The implementation of anti-tamper (AT) technology as one vital strategy for preserving US military superiority. (Communiqué DoD 5200.1-M) In response to this need, many AT technologies have been developed including AT coatings for securing electronic components and devices. However, the use of successful AT coatings is impeded by lack of a manufacturing process that: 1.) Possesses the capacity ...

The innovation presented in this proposal involves the use of a liquid melt thermal spray process for cost effective rapid prototyping of near-net shape tooling for the lay up of advanced composite materials. The process uses a focused beam of charged liquid droplets to form tooling directly from three-dimensional computer generated drawings eliminating traditional steps associated with fabricatio ...
