Adroit Systems, Inc. will develop a Pulse Detonation Synthesis (PDS) process to manufacture ceramic powders from gas-powder reactant mixtures more efficiently and inexpensively than current methods. A high combustion rate and simple design make the PDS system capable of mass producing these powders, which are used as raw materials for high-temperature, high-performance ceramics and ceramic composi ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

Development of reliable (Q-) switching and isolation materials is being sought for near-to-mid infrared lasers for safety, extended life and fiber optic communication. The voltage or E-field controlled (Q-) switching materials such as Pockels cells and liquid Kerr cells are not reliable for long term operation in tactica applications due to crystal surface (e.g., KDP, ADP) degradation by moisture ...

An adaptive attitude control system for a space-based interceptor will ameliorate the effects of torque disturbances when firing a divert thruster with the line of force offset from its center of mass. The adaptive control algorithm is based on a simplified version of a model reference adaptive control concept. It possesses two features: (i) more robust performance for the interceptor guidance and ...

WE PROPOSE TO SEARCH FOR NEW SUPERCONDUCTORS THAT ARE SIMILAR TO THE PEROVSKITE-BASED HIGH TEMPERATURE SUPERCONDUCTORS (HTS), BUT WITH THE OXYGEN REPLACED BY A CHALCOGEN, THAT IS SULFUR, SELENIUM OR TELLURIUM. WE BELIEVE THAT THE HTS COPPER OXIDES ARE NOT A UNIQUE ACCIDENT OF NATURE, BUT THAT THERE ARE OTHER COMPLEX CHEMICAL COMPOUNDS THAT COULD ALSO BE SUPERCONDUCTING. AN OBVIOUS PLACE TO LOOK WO ...

To improve automated target tracking and correlation for strategic defense, this proposal models the dynamic behavior of manuevering vehicles by allowing target heading and speed, or their derivatives, to undergo independent diffusion processes. Current methods for surveillance sensors model diffusion in geographically fixed coordinate systems and fail to exploit course/speed nonlinearities, and k ...
