1. A method of accelerating a body to a high velocity, comprising the steps of:

  • filling an oblong vessel with a compressed fuel-oxidizer mixture, said oblong vessel having initially closed ends and having a large inner diameter compared with outer dimensions of said body,propelling said body at supersonic velocity into said oblong vessel, said body generating bow shock waves and oblique detonation waves said bow shock waves and said oblique detonation waves intersecting and interacting within said oblong vessel prior to reaching an inner wall of said oblong vessel,detonating said fuel-oxidizer mixture with said oblique detonation waves causing forward thrust and acceleration of said body by pressure generated by denotation of said fuel-oxidizer mixture and expansion of high-pressure gases to the rear of said body.
