High-Resolution Digital Linearity Distortion Compensator

Vibration and shock attenuation is the focus of this SBIR project. We offer to demonstrate the feasibility of the Smart Engine Mount with Energy Managing Continuous Structural Elements system concept suitable for use in airborne vehicles such as E-2Caircraft. Excess vibration energies will be channeled and attenuated inside the Smart Engine Mount whose continuous and connected elements will have energy flow control and energy managing capabilities. This innovative Smart Engine Mount concept may beused as an effective semi-active and hybrid barrier between vibration energy generated by an engine and sensitive optical and electrical components inside an aircraft. The entire smart mount will be composed of three main layers in which semi-active andhybrid energy-managing elements will be embedded. In other word, vibration and shock disturbances injected into the engine mounts will be confined, diverted, converted, absorbed, steered, and dissipated using embedded passive elements and activeactuators. It is this energy-managing feature of the smart mount that makes our concept unique and effective. In addition, our approach will be distinct when compared with conventional discrete mounts because our smart mount will be made of continuouselements that are interconnected to make the entire mount system significantly more effective. Finally, the semi-active feature of the proposed Smart Engine Mount will have the capability of changing it stiffness and/or damping rates in an on-off mannerto accommodate operational changes.More effective engine mounts may be used on many of the current commercial piston and turboprop aircraft as well as helicopters. The combination of improved vibration isolation while maintaining static alignmentconditions under shock loads will also be applicable to better isolating a variety of military and commercial power trains from the rest of the vehicle. In addition to airborne types, these vehicles include passenger automobiles, commercial trucks, marinevehicles such as submarines and surface ships.
