An air breathing, jet propulsion engine of either ram jet or turbojet type is provided by an open-ended, elongate, tubular casing having a lead section at one open end thereof and means associated with said section for compressing entering air substantially adiabatically, and having a smaller, open ended, elongate, and perforate tubular member as a combustion chamber positioned concentrically within and along the casing to form therewith a relatively short intermediate section defining a convergent annular entry followed by an annular throat as the sole thrust nozzle and a discharge passage around and along the perforate tubular member providing a discharge section, such passage being wholly and progressively divergent to termination thereof at the opposite open end of the casing as a thrust orifice. A burner provides for combustion of fuel in the combustion chamber, whereby mass flow of gases of combustion through the perforations of the perforate member into the expanding supersonic airstream passing therearound heats such airstream and increases its velocity. The perforate tubular member is preferably equipped for adjustment of the opening size of its perforations and for adjustment of its position longitudinally with respect to the casing.

An air breathing, jet propulsion engine, comprising an open-ended, elongate, tublur casing having a lead section at one open end thereof with means adapted to receive a stream of atmospheric air and compress it substantially adiabatically to at least twice ambient pressure, a second, relatively short, intermediate section in longitudinal alignment and flow communication with said first section, and a third, elongate, discharge section at the opposite open end of the casing and in longitudinal alignment and flow communication with said second section; a smaller, open-ended, elongate and perforate tubular member concentrically positioned within said second and third sections of the casing as a combustion chamber and configurated to define with said casing as the entrance to said second section thereof a thrust nozzle having an annular, convergent entry for air followed by an annular throat for initiating supersonic flow of air and to define, further, a wholly and progressively divergent discharge passage around and along said perforate tubular member which opens at said opposite open end of the casing as a thrust orifice for supersonic flow of a heated, nozzle airstream from around the combustion chamber, said discharge passage being in flow communication with the combustion chamber along the length thereof by way of the perforations of said perforate tubular member; and means for establishing combustion within said combustion chamber for mass transfer by convection of hot gases from said ombustion chamber to said supersonic flow of air so as to supply heat to and increase velocity of the airstream flowing through said wholly divergent discharge passage and out said thrust orifice, wherein the engine is of turbojet configuration having air pressurizing turbine means in the lead section of the casing, said turbine means comprising a turbine wheel, a low pressure fan section, and a relatively high pressure compressor and turbo section having nozzles directed against said turbine wheel, the nozzles of the turbine means each substantially conforming structurally and functionally to the nozzle of the intermediate and discharge sections of the casing.
