Abstract:Rotating Detonation Engines (RDEs) have recently acquired popularity in propulsion systems as a realistic way to boost thermal efficiency using Pressure Gain Combustion (PGC). They are easier to design and build since they include few or no rotating components. Theoretically, they can give higher thrust-to-weight ratios than traditional jet engines that use deflagration, on a smaller scale of working. Unlike Pulse Detonation Engines (PDEs), RDEs provide near-steady exit conditions and thrust, making them excellent and versatile for a wide range of applications. In this research, we intend to explore the feasibility of employing an RDE unit as an add- on or booster to an existing vehicle. This project aims to analyze the possibility of using a Rotating Detonation engine as an auxiliary support thruster in place of a Scramjet in the SR-71 Black Eagle Fighter jet model. The results found through simulation indicate that RDE can overcome the main shortcomings of the Scramjet engine which is the operational condition of Mach 1 or higher flow velocity of aircraft for using liquid fuel for combustion. Since RDE is dependent on Liquid fuel we need not worry about using Solid fuels as in the Scramjet engine. Further into the study we conducted, we tried to understand the noise generated by the combustion system and its effects which cause the de-stabilization.
