Fluid mechanics of pulse detonation thrusters
چکیده انگلیسی

The advantages of constant volume combustion cycle as compared to constant pressure combustion in terms of thermodynamic efficiency have focused the researches of advanced propulsion on detonation engines. The paper gives coverage of efforts undertaken during past decades in adjusting detonations for propulsion applications, and highlights new challenges in studying fluid flow dynamics relevant to onset of detonation.


► The advantages of detonation mode for propulsion as compared to constant pressure combustion are developed.
► The possible structure of pulse detonation thrusters is discussed.
► The necessary and sufficient conditions for a reliable detonation onset in a thruster are derived.
► The sensitivity of detonation onset to variation of governing parameters and chamber geometry is demonstrated.
