Abstract

This paper describes the design, operation, construction and demonstration of a new type of high bandwidth unsteady temperature sensor based on fibre optics, and capable of operating in a high speed multi-stage research compressor with flow representative of jet engine conditions. The sensing element is an optical coating of zinc selenide deposited on the end of an optical fibre. During evaluation in aerodynamic testing, a 1 K gas temperature resolution was demonstrated at 9.6 kHz and an upper bandwidth limit of 36 kHz achieved.
