CONVECTIVE HEAT FLUX TRANSDUCER DEVELOPMENT.
Abstract
This report describes a development program undertaken to complete work begun during the X-20A contract on a surface heat flux transducer. It was to operate with a convective input up to 50 BTU/ft.2-sec at temperatures up to 3000 F. The concept of the sensor was to generate a temperature difference by using two surfaces which exhibit different emittances and controlling this temperature difference by designing a proper conductive path between the surfaces. Previous analyses indicated that this temperature difference was a function of the input heat flux. A new study revealed the truth of the situation in that the sensor was actually operating as a thermal equilibrium device. One more test was run to verify these conclusions in order that sensor capabilities could be detailed. (Author)
