Engine Use In Hybrid Rocket - A Review
Graduate Research in Engineering and Technology, 2022 Despite all the other rocket motors on the market such as solid and liquid. A historically failed motor was in the market which was handicapped in performance but now with technological development in the previous years, hybrid rocket motor is the most influential talk in the market. Deeper in the paper we will discuss the hybrid motor focusing on the
