Ultrasonic Solid Propellant Burn Rate Measurement System

USBRMS is a mission critical equipment for the measurement of burn rate of solidpropellant used in rocket motors. It works on the ultrasonic pulse echo sensing technique,capable of generating upto 1000 burn rate measurements per second. As compared to theconventional BEM method, USBRMS has better accuracy, repeatability and lesser safetyrequirements among others. The burn test chamber is rated to 300 bar pressure ,3000 °C.

Use Cases

Solid propellant motors are used in booster stages of rockets/missiles. The application of the ultrasonic pulse-echo technique is to measure the instantaneous burning rate of propellant. It involves transmission of an ultrasonic pulse through the web of the propellant and reception of the reflected echo pulse from the burning surface/combustion gas interface by the same transducer.
