Abstract

681,378. Gas turbine plant; jet propulsion plant. ARMSTRONG SIDDELEY MOTORS, Ltd., and ALLEN, S. Oct. 16, 1950 [Nov. 30, 1949], No. 30700/49. Class 110(iii) Fuel is supplied to the exhaust reheat chamber of a gas turbine engine by means of an ejector to which high pressure gaseous fluid, such as air from the compressor or preferably combustion products from the combustion chamber, is supplied along a passage 21 having a constriction 25. The constriction gives a pressure ratio of at least two to one so as to provide a sonic speed of flow in the constriction. Fuel is supplied from the annular chamber 29 to the annular passage 28 which is downstream of the constriction and faces partly downstream so that an ejector action, is set up. The supply passage diverges at 26 downstream of the constriction thereby producing a flow at supersonic speed. The invention is shown applied in the case of a reheat chamber of a gas turbine jet propulsion engine, a valve 22 being fitted in the passage 21. The supply passage 21 downstream of the constriction and nozzle may be coiled round the jet pipe so assisting in vaporising the fuel. Alternatively, it may pass into the interior of the jet pipe and form a coil therein. An ignition device 36 which may be as described in Specification 674,641 is fitted in the reheat chamber.
