A multi-modal vibration energy harvester has been developed for use on a helicopter transmission. The harvester is based on a topology optimised spring-steel cantilever-beam, with a pair of [011] poled Mn-PMN-PZT relaxor ferroelectric single crystal

Noise and vibration is a serious problem in all types of aircraft. Any techniques that lower cabin noise and vibration levels by even a few decibels with little or no weight or performance penalties are worth pursuing. Propeller synchrophasing is one

This paper reports on the design, modelling and measured response of a high frequency vibration energy harvester that uses relaxor ferroelectric transduction. The ultimate goal is to build a harvester capable of extracting energy from the kilohertz f

[Abstract] Interior noise and vibration can be a serious problem in military propeller aircraft. Noise levels often exceed 100 dB, and typical vibration levels can be hazardous to sensitive cargo. This noise and vibration is dominated by the propelle
