Abstract : Double-sided, high-frequency response heat flux gauge for use on metal turbine blading consists of a metal film (1500A) resistance thermometer sputtered on both sides of a thin (25 um) polyimide sheet. The temperature difference across the polyimide is a direct measure of the heat flux at low frequencies, while a quasi-ID analysis is used to infer the high-frequency heat flux from the upper surface history.
