Abstract

Abstract

The experimental system with a closed bomb was employed to discuss the characteristics of 4/7 high-nitrogen solid propellant burning rate enhanced by plasma. The plasma energy transferred into the closed bomb was measured by the utilization efficiency of the plasma generator electrical energy. A transient burning rate formula of propellant including the influence of pressure gradient and an enhanced gas generation rates coefficient by electrical power was presented. The enhanced gas generation rates coefficient of 4/7 high-nitrogen solid propellant is equal to 0.005 MW^-1. Compared with the burning rate formula given by Woodley, the pressure curve simulated by the transient burning rate formula is in better agreement with the tests. And the transient burning rate formula can describe the combustion process of solid propellant by plasma more accurately.
