Analysis and Measurement of High Frequency Solid Propellant Responses.

Abstract

This report describes a program to study high frequency solid propellant responsed. The experimental techniques are based on the application of the magnetic flowmeter. A magnetic flowmeter burner was designed and constructed to evaluate the direct method of pressure-coupled response measurement. Response measurements were obtained for two formulations of AP/HTPB composite propellant at pressure oscillation frequencies from 4000 to 20,000 Hz. The measured data displayed consistent trends in both the real and imaginary parts of the pressure-coupled response function. The unsteady gas phase model of T'ien was used to predict response function trends as a function of frequency. The magnetic flowmeter techniques are currently being applied to the direct measurement of a solid propellant high frequency velocity-coupled response. Keywords: Pressure coupling; Velocity coupling; Acoustic admittance; Pressure-coupled response; Velocity-coupled response, Magnetic flowmeter.
