Abstract
The project “Advanced Hybrid Rocket Engine Simulation” (AHRES) aims to develop software for hybrid rocket engine performance calculation. The German Aerospace Center (DLR) has equipped a hybrid rocket testbed with an ultrasonic regression rate measurement system, which can track the regression rate at 2 points of the fuel grain. Within this paper the ultrasonic system is described in detail. The problem of calibrating the ultrasonic system and the correction of errors due to heat profile and pressure is discussed. The results of a 10 s hot test run are presented.
