Not Available A number of shortcomings in current active control systems preclude their widespread use: 1) need for higher actuator authority, 2) need for robust compact actuators with ease of implementation, and 3) need for improved power handling and driving electronics. The innovation proposed is a new approach to active material and electronic systems for the control of vibrations in aeroelas ...

Not Available Lightweight structures are demanding for high inach vehicles and engine exhaust impinged structures subjected to high temperatures. Currently used polyimide composites have limited service temperatures whereas titanium alloys have much higher densities than those of advanced composites. This Phase I research proposes the processing of high temperature sandwich structures using micro ...
