Abstract:

This study is Phase III of a proposed four phase program investigating various problems involved in using radio-frequency induction heating as a means of simulating aerodynamic heating. A method of experimentally designing work coils for a given surface power density distribution by measuring the magnetic field intensity is discussed. A series of tests are described which heaed a wing leading edge section. These tests simulated the expected surface power density distribution for a gliding re-entry flight. The temperature was automatically controlled over a period of approximately 100 minutes and attained a maximum value of approximately 3000 F. Tests for the purpose of determining work-coil efficiencies are discussed. Three methods of measuring the power produced by induction heating are described. The fields produced by flat work coils are compared to theoretical calculations. Also included is a discussion of measuring work-coil impedances. Author
