Electronic Unit for Ultrasonic Solid-propellant Burn Rate Measurement System

The paper envisages the development of a controlling electronic unit for the Ultrasonic Solid Propellant Burning Rate Measurement System (USBRMS). The electronic unit is an embedded system, consists of FPGA, ARM processor and Microcontrollers as its controlling parts. The product is designed and developed for the measurement of burning rate of solid propellant using in rocket motors. The system works on the principle of ultrasonic technique by measuring repeatedly the thickness of a cylindrical propellant specimen burning in a combustion chamber. User can measure the burning rate of different solid propellant samples using USBRMS system, which can be used for predicting the performance of large solid propellant motors used in space/strategic applications.
