An airframe integrated scramjet propelled vehicle has advantages for application to several missions. In its simplest form, such a vehicle will combine the features of quick reaction, low vulnerability to counter attack and better propulsion efficiency. The Supersonic Combustion Ramjet (SCRAMJET) engine has been recognized as the most promising air breathing propulsion system for the hypersonic...

In this study, one-dimensional detonations in ammonia/hydrogen-air mixtures are numerically investigated by solving the fully compressible Navier-Stokes equations with detailed chemistry. Pulsating instabilities single-mode observed during detonation wave propagation, accompanied periodic coupling and decoupling of lead shock reactive front. The ratio between driver pressure initial determines ...
