Abstract

859,993. Controlling jet propelled aircraft. BOEING AIRPLANE CO. June 20, 1958, No. 19877/58. Class 4. [Also in Group XXVI] A jet propulsion nozzle provided with means to divide the jet stream at a number of smaller streams so as to reduce the noise level, also with means to vary the outlet area of the nozzle (see Group XXVI) is also provided with a jet deflecting device 42 which is shown in its retracted position in Fig. 2 and in the operative position in Fig. 8. When the jet deflecting device 42 is moved to the operative position shown in Fig. 8, the sleeve 42 bears against a cam 22 so that the flap 12 is moved to an outward portion. Also, diverter elements 44 are projected into the gas stream so as to deflect the gases towards the reversing vanes 42b. Specifications 831,152, 835,134, 841,580 and 859,994 are referred to.
