A combined ramjet and rocket engine, operates as a ramjet in atmosphere, and a rocket engine in space is provided with a rectilinear duct. The engine has interior of the rectilinear duct paired and hinged rectilinear baffles which move from one of the duct walls. These hinged rectilinear baffles move into and out of the planar duct wall and define both the constriction of the Venturi for the ramjet engine configuration or the closure of the duct for the rocket engine configuration. The hinged rectilinear baffles are given leading and trailing wall surfaces so that during movement within the duct for the ramjet configuration, alteration of the slope of the collector and diffuser of the Venturi can occur. The hinged rectilinear baffle bordering the diffuser is manifolded to supply fuel when the engine is ramjet configured and fuel and oxidant when the engine is rocket engine configured. The manifolded baffle bordering the diffuser is directly exposed to combustion and serves to preheat the fuel and/or oxidant flow.

[ What is claimed is:] [1.] A combination ramjet and rocket engine comprising:a rectilinear duct defined by upper and lower parallel walls and left and right parallel walls, the rectilinear duct having an intake, an outlet, and a combustion chamber between the intake and the outlet;at least a forward rectilinear baffle and rear rectilinear baffle, the forward rectilinear baffle and the rear rectilinear baffle each having first and second sides with parallel edges adjacent the left and right parallel walls of the rectilinear duct respectively, each forward rectilinear baffle and each rear rectilinear baffle having sufficient dimension between to fully block the rectilinear duct between the left and right parallel walls when disposed across the rectilinear duct between the left and right parallel walls;a hinge joining the forward rectilinear baffle at a rear edge to the rear rectilinear baffle at a forward edge;means mounting at least one of the forward and rear rectilinear baffles at a parallel edge opposite the hinge for hinged movement with respect to one wall of the rectilinear ductsmeans mounting the other of the forward and rear rectilinear baffles at a parallel edge opposite the hinge for sliding movement with respect to one wall of the rectilinear duct;means for moving the forward rectilinear baffle and the rear rectilinear baffle at the hinge towards and away from a position fully blocking the rectilinear duct to a position adjacent a wall of the rectilinear duct whereby the baffles when moved away from fully blocking the rectilinear duct form a venturi having a collector adjacent the inlet, a constriction, and diffuser adjacent the outlet; and,means for supplying fuel to the combustion chamber of the engine in the rear rectilinear baffle adjacent the diffuser.
