Abstract
HyImpulse is developing a 75 kN hybrid rocket motor based on a LOx (liquid oxygen)/paraffin propellants combination that will equip SR75 (sounding rocket) and SL1 (3 stages small launcher) rockets in the coming years. The development of such thrust level hybrid motor is challenging and has been supported by a 10 kN small-scale motor to investigate and optimize different components of the large motor, such as paraffin mixture, nozzle erosion, oxidizer injection etc. More than hundred firing tests have been performed with this motor which provided highly valuable data and knowledge. The paper will provide an overview of the hybrid motors production and testing capabilities of HyImpulse. It will also present some results obtained from combustion tests to highlight the progress that was achieved so far.
