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 APHTPB 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 Tien 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.
