Optical Pressure-Temperature Sensor for a Combustion Chamber

· Marshall Space Flight Center A compact sensor for measuring temperature and pressure in a combustion chamber has been proposed. Heretofore, independent measurements of high pressures and temperatures in combustion chambers have not been performed. In the original intended application, the combustion chamber would be that of a rocket engine.

Combustion Monitoring with Pressure Sensors.

Kistler's piezoelectric pressure sensors are used in continuous operation for closed loop combustion control in internal combus-tion engines. They enable the performance of engines to be controlled constantly. This allows combustion optimization for a better efficiency and minimizes emissions. In addition to this, predictive maintenance becomes easier.

Optical Pressure-Temperature Sensor for a Combustion Chamber

able pressure sensors have been capable of surviving the thermal environment of a combustion chamber without the use of sensing lines or helium-filled cavities. Pressure-measurement signals obtained by use of sensing lines or helium-filled cavities have altered power spectra that make the signals unsuitable as feedback signals for control purposes. The proposed sensor would include two ...
