| Abstract: | By measuring the reflection time of ultrasonic echo in the propellant continuously, the location of the burning propellant surface is identified, and the burning rate of propellant acquired. This ultrasonic method of measuring the burning rate is used to determine continuous in situ burning rate in different setting pressure variable condition. The application of the ultrasonic method of measuring the buring rate in the field of studying the steady-state and nonsteady-state burning rate characteristics of propellant and burning rate characteristics in various motor is introduced. The characteristics and adaptabilities of the method are evaluated, and a suggestion of developing this technology in internal institutes is presented. |
