This Small Business Innovation Research Phase I project will develop refractive x-ray lenses for medical, industrial, scientific, and directed-energy applications. Previously, ordinary optical refractive lenses were assumed to not work at x-ray wavelengths because refractive effects were very small. Reflective and grazing angle techniques are usually limited to the soft x-ray region of the spectru ...

The objective of this proposal is to demonstrate the feasibility of vacuum micro-packaging for devices such as MEMS gyroscopes and accelerometers. Vacuum is critical for high Q-factor, surface-micromachined MEMS. Robust, low-cost solutions are needed for applications such as guided munitions and unattended sensors. Proposed work focuses on long-term reliability issues, such as outgassing, perme ...

We propose to engineer a low-cost computer-controlled optical diagnostic system for measuring sound speed, thermal diffusivity, density, and velocity. This system will use laser-induced thermal accoustics (LITA), a transient-grating technique capable of making accurate single-shot measurements in luminous, multiphase, high-pressure flows. The LITA signal intensity is quadratic in fluid density f ...

The complex HEV power systems necessitates flexible and dynamic simulation software providing tools for evaluating, characterizing and optimizing these systems. Existing software have neglected to characterize significant component data such as heat loads, cabin cooling requirements, battery thermal management, and heat rejection. Vehicle performance (accounting for environmental conditions and s ...

The Pulse Detonation Engine (PDE) is an intermittent combustion engine that relies on traveling detonation waves for the combustion and compression elements of the prosulsive cycle. This engine may be used as a low cost propulsion system in defense flight vehicle system applications or as the low speed cycle for a high Mach number combined cycle engine system. The mechanical simplicity of this e ...
