Abstract

670,247. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 2, 1949. [Aug. 17, 1948; Jan. 4, 1949] Nos. 21731/48 and 226/49. Divided out of 665,446. Class 110(iii). [Also in Group XII] The reheat combustion chamber of a gas turbine jet propulsion engine has means for injecting fuel without ignition into the exhast gases at a plurality of points distributed over a transverse section of the exhaust pipe, means to form a stabilized combustion zone similarly distributed over the section of the exhaust duct downstream of the fuel injection zone and means to control the lateral spread of the fuel between the fuel injecting and the stabilizing means. The exhaust gases from a turbine 1, Fig. 1 are reheated in passing to the propulsion nozzle 7. The reheating apparatus comprises a group of fuel injection nozzles 9 distributed over the cross-section of the duct and a plurality of flame stabilizing baffles 10 similarly distributed in a region downstream of the nozzles 9. The nozzles 9 inject fuel upstream into a tubular member 12, Fig. 2, which controls the lateral spread of fuel at the baffles 10. Normally, it is not desired to allow fuel to leave the upstream end of the tube 12, but at high fuel flows it is difficult to prevent it. In this case, the flow of this fuel may be controlled by flaring the end of the tube outwardly as at 13 or each tube may be provided with a sheath 14, Fig. 2 or the whole system of tubes a sheath 15, Fig. 1. In a modification, a rectangular baffle plate which partially blocks off the upstream end of the tube 12 may be provided. In another modification only some of the jets 9 are provided with tubes 12, the remaining jets discharging freely into the gas stream. Preferably, each fuel jet 9 has a stabilizing baffle 10 and each baffle houses an ignition device. The first Provisional Specification also describes the proposal to connect the control of the reheat fuel with that of the nozzle area. The ignition means in the baffles 10 may be operated successively as the nozzle area is increased. Specification 665,446 is referred to. Specifications 606,176 and 659,800, [both in Group XXVI], also are referred to in the Provisional Specifications.
