Aerodynamic instability`s pumping or rotating detachment type phenomenon detecting system for e.g. jet engine, has microelectromechanical system type device for transmitting data to data receiving unit by radio waves

摘要

The system has a self-powered microelectromechanical system (MEMS) type device (3) for measuring the data of the variations for a parameter such as gas pressure in a compressor, of the gas flow in the compressor of a gas turbine engine and for transmitting the data to a data receiving unit (12) such as housing, by radio waves. The device is housed in a screw that is screwed on a case of the compressor.
