Abstract

750,618. Jet propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 3, 1953 [June 5, 1952], No. 15364/53. Class 110(3) [Also in Group XXXIII] A jet propulsion unit is characterized by the provision of a jet deflecting device comprising a plurality of guide vanes extending outside the normal flow path of the jet and spaced therealong and controllable means for urging said jet towards said vanes, and a device for varying the area of said nozzle comprising fluid-injecting means opening into said jet in a generally crosswise direction with respect thereto at the periphery of said jet and upstream of said vanes, said fluid injecting means being designed for forming a transverse screen-like jet adapted to reduce the effective area of said nozzle and to urge the boundary layers of said jet clear of said vanes. The exhaust nozzle 35 carries deflector baffles 43 and a centrally disposed body 38 formed with outwardly and rearwardly directed orifices 40, 41 supplied with gas under pressure through a valve - 44, whereby the exhaust stream may be diverted outwardly to pass through the baffles 43. An additional orifice 36 extends circumferentially round an annular chamber 36a also supplied with pressure gas through a valve 45, whereby the exhaust stream may be contracted and, when orifices 40 and 41 are inoperative, prevented from spreading outwardly into contact with the rearmost baffles 43. Specifications 696,088 [Group XXXIII], 745,630 and 750,601 are referred to.
