A low-cost rocket or thruster has a low-cost propellant injector, in which fluid fuel and oxidizer are injected into a combustion chamber. The walls of the combustion chamber are protected from the high temperatures of the combustion by a grain of solid propellant, the surface of which tends to melt andor vaporize in the presence of combustion temperatures, and thereby protects the walls of the chamber. The low-cost propellant injector may not mix the fluid fuel and oxidizer effectively, so that pockets of noncombusted gas may occur within the chamber. T...
[ What is claimed is:] [1.] A rocket engine, comprising:a source of liquid oxidizer;a source of combustible fluid propellant;a chamber with walls, said chamber being coupled to a combustion product ejection port;a propellant injector coupled to said source of combustible fluid propellant, for injecting said propellant into said chamber at a rate;an oxidizer injector coupled to said source of liquid oxidizer and to said chamber, for injecting oxidizer into said chamber at a rate no less than a rate sufficient for complete combustion of said combustible fl...
