Abstract

955,013. Jet propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Nov. 17, 1961 [Nov. 18, 1960], No. 41285/61. Heading F1J. A composite jet engine comprises at least two channels in one of which is disposed a gas turbine driven air compressor, air from the compressor being passed into the second channel where it is utilised in a combustion chamber which supplies gases to a turbine which drives an air compressor disposed in that channel, means being provided for heating the air discharged from the second air compressor. In the embodiment shown, the engine comprises two channels 1, 2 each having a propulsion nozzle of convergent-divergent form and of variable area. The two channels have a common air intake also of convergent-divergent form and of variable area. A gas turbine engine is disposed in the channel 1 and comprises an air compressor 11, combustion equipment 13, a turbine 10 driving the compressor 11 and a separate power turbine 9 which drives an air compressor 7 disposed upstream of the engine. The exhaust gases from the engine discharge through the nozzle 3. Air from the compressor 7 passes through a duct 14 to a combustion chamber 16 disposed in the second channel, 2, gases from the combustion chamber discharging to the turbine 17 which drives an air compressor 19 disposed in the annular passage 20 around the combustion chamber and turbine assembly 16, 17. Air from the compressor 19 may be heated in the passage 20 by means of a burner device 27. The gases discharged from the turbine 17 together with air from the compressor 19 pass through the propulsion nozzle 4. The gases and air may be reheated in the duct 21 by means of a burner device 22. The stator blades 25, 26 of the air compressor 19 may be angularly adjustable; also, a pivoted flap 6 may be provided to control the air flow into the two channels. The duct 2 may be operated as a ram jet unit when the air compressor 19 is inoperative the ram air being heated in the combustion equipment 20, 27.
