Abstract

979,474. Gas turbine jet engines. UNITED AIRCRAFT CORPORATION. Aug. 29, 1962 [Sept. 18, 1961], No. 33144/62. Heading F1J. In a by-pass type gas turbine jet engine having a main propulsion nozzle and at least one secondary propulsion nozzle for discharge of the by-pass air, the main nozzle comprises a vertically extending slot-shaped outlet of rectangular cross-section comprising verticallyextending and converging side walls and horizontally-extending and diverging top and bottom walls, the secondary nozzle being disposed adjacent to and in vertical alignment with the main nozzle. The engine shown in Figs. 1 and 2, comprises a low pressure compressor 14, part of the air discharged thereby passing into the high pressure compressor 16, combustion equipment 18 and turbine 20, the turbine exhaust gases discharging through a main propulsion nozzle 36, the outlet 44 of which is in the form of a vertically extending rectangular slot. The remaining portion of air delivered by the compressor 14 passes into a pair of by-pass ducts 32, 34 extending along the top and bottom of the engine, the air discharging therefrom through secondary propulsion nozzles 26, 28 which are disposed above and below the main nozzle outlet 44 respectively. The stream of by-pass air issuing from the nozzle 28 serves as an acoustic barrier against the noise of the high velocity jet stream discharging through the nozzle outlet 44. The secondary nozzles may terminate short of the main nozzle. Specifications 894,801 and 912,293 are referred to.
