Optical Systems For Gas Turbine Engines

Abstract

The use of optical systems for data acquisition and transmission is becoming increasingly popular for aviation applications. Features such as weight and immunity to high levels of E.M.C. are distinct advantages over conventional electronic systems. In some cases optical transducers provide a means of measurememt which would otherwise be impossible. One such transducer is the Turbine Blade Pyrometer Transducer. This instrument determines gas turbine blade temperature by measuring emitted visible and near infrared radiation. The transducer is an engine mounted electro optical system which provides a voltage output proportional to turbine blade radiance. As such it must be designed to withstand the demanding environment of a gas turbine engine.© (1986) COPYRIGHT SPIE--The International Society for Optical Engineering.
