Design and Study of Swirl Injector of Pulse Detonation Engine

Future Indian Air force and Navy Capabilities indicate the need for a supersonic cruise missile. Therefore, there exists a need for a low cost, light-weight, and efficient means of supersonic propulsion. In this paper my main emphasis on Pulse Detonation Engine, in pulse detonation engine humphey cycle is used ,PDE has thermodynamic efficiency greater than 50% as compared to 35% for present day propulsion technology constant-pressure Brayton cycle currently in use in gas turbines/ramjets/scramjets. Pulse Detonation Engines (PDE’s) represent an upcoming new approach to propulsion and with the simplicity of its construction; PDE’s produce thrust more efficiently than the current engines and produces a higher specific thrust. Since current rocket engines require heavy and expensive pumps; with mechanical simplicity and thermodynamic efficiency PDE’s offer a viable alternative to reduce the cost of launching spacecraft.
