Abstract:

A theoretical study was made to determine the performance of a detonation propulsion system using plasticized explosives. Steady-state and shock-hydrodynamic calculations were completed for free-expansion detonations, where the explosive gases are free to expand from the vehicle mass after impacting the vehicle, confined detonations, where recoil mass is used to constrain the expansion, and totally confined detonations, where the momentum transfer to the vehicle mass and the conversion of detonation energy into vehicle kinetic energy are maximized. The effects upon propulsion performance of separating explosive charges from the vehicle mass, giving the explosive charge an initial velocity, and stacking explosive charges between solid materials, were also studied.
