Abstract

907,526. Jet propulsion nozzles. GENERAL ELECTRIC CO. Feb. 13, 1961 [April 1, 1960], No. 5246/61. Class 110 (3). A jet propulsion nozzle comprising a convergent-divergent primary nozzle-section for receiving the engine working fluid and a secondary nozzle circumferentially spaced about the primary section to form a passage for the introduction of secondary fluid into the nozzle, in which the primary nozzle is axially movable relative to the secondary section to vary the throat area and discharge orifice of the nozzle, has throttle means in the passage connected to the primary nozzle so as to throttle the secondary air flow in accordance with the position of the primary nozzle. The jet propulsion nozzle comprises a primary convergent-divergent nozzle section 1 formed by a set of overlapping flaps 9 which slide axially along curved track elements 12 to vary the area of the throat 10 and primary discharge orifice 11. Track elements may be provided for alternate flaps only. The track elements 12 are mounted in a passage formed by the secondary nozzle section 2 surrounding the primary nozzle through which flows the secondary air which may be obtained from the compressor of the jet propulsion engine or may be ram air. The flaps 9 are actuated by motors 18 through linkwork 19, 20. To vary the secondary air flow, a throttle 22 is mounted on the rod 19. Movement of the throttle 22 relative to the frusto-conical passage 23 provides a throttling area variation which is linear with respect to movement of the primary nozzle 1. If desired, the passage 23 may be formed paraboloidally, hyperbolically or according to any desired function. Specification 896,484 is referred to.
