Abstract:

Radio-frequency inducti n eating as a means of simulating aerodynamic heating was studied. The techniques used to increase the deliverable surface-power density are discussed with particular emphasis on the capabilities and limitations on the use of water-co led tubing for work coils. Methods of surface heating materials with very high electrical resistivities are discussed. The possibility of using an induction-coupled plasma torch for aerodynamic heating simulation is explored and the results of some preliminary tests with this type of torch are presented. The problem of voltage breakdown between a heated specimen and an air-spaced work coil is investigate as influenced by spacing, coil configuration, magnetic field, and specimen temperature up to 2500 F. The results of voltage breakdown tests on commercially available materials which can be used as solid insulation between a work coil and a heated specimen at 3000 F are presented. Author
