Rotating Detonation Engine (RDE) has all the advantages including high-efficiency and high thrust density without compression stages for the future generation engine. Nevertheless, RDE is still at an infancy stage that need further study specifically to discover the best mixing scheme for combustion stability. Thus, the aim of this study is to develop and test the new mixing scheme of RDE using asymmetric vortex shape on small scale RDE to improve mixing and stability. Initiation strategy by using pre-detonator with 10bar of detonation pressure. RDE with asymmetric vortex shape was successfully operate with average pressure of 4.5bar and 6 kHz of frequency.
