Solid Propellant Admittance Measurements by the Driven Tube Method.

Abstract

The progress made during the third year of an investigation to measure the response of a burning solid propellant to oscillatory flow conditions is presented. In this study a modification of the impedance tube technique is used to measure the response over a wide range of frequencies. Improvements in the data reduction program are discussed. These include a more accurate method of computing the temperature distribution in the burner tube and a technique for determining the response from pressure amplitude measurements only. A high-pressure facility and minicomputer-based data acquisition system are also discussed in the report. Data taken at 300 psig indicate that the combustion process of the solid propellant periodically drives and damps acoustic oscillations under most of the test conditions encountered. (Author)
