The Double Helmholtz Resonator as a Possible Tool for the Determination of the Response Function of Solid Rocket Propellants in the Low Frequency Range

摘要

A theoretical analysis of a double Helmholtz resonator (HR) is presented. The laboratory utilization of a HR burner is recommended to measure the admittance function of propellants in a wide frequency range. The performance of a burner is analyzed and the quantities to be measured in order to deduct meaningful information about the propellant from test runs are indicated. The burner may use T-burner components. Its use with and without a surge tank is mentioned.
