Investigation of rocket/ramjet with both solid propellant and liquid fuel

Lei Xi

Abstract

Solid liquid rocket/ramjet was selected and investigated with the stable work conditions for a larger flight region. The method of theoretical calculation and optimization of design were determined and experimented.Simulation test on the conditions of larger flight region was conducted.Results show that the solid liquid rocket/ramjet is a better ramjet engine for military application in future. The optimization can be reached through regulating the mass ratio of liquid fuel/solid propellant.
