Abstract

823,658. Deflecting propulsion jet on aircraft. SOC. NATIONALE D'ELUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Nov. 28, 1957 [Dec. 6, 1956], No. 37155/57. Class 4. Means for deflecting a propulsion jet on aircraft comprises a plurality of circumferential obstacles which may be moved within the jet pipe and blowing nozzles which exhaust round the inner periphery of a divergent extension of the jet pipe, the operation of a blowing nozzle being associated with the retraction of an adjacent aligned obstacle to facilitate adherence of the deflected jet round the surface of the divergent extension. The jet pipe 1 is slotted circumferentially at 3 for four abstacles 4 each mounted on an arm 5 pivoted at 6 on the jet pipe and connected by a rod 8 to a pilot's control member (not shown). The jet pipe carries a divergent extension 2 formed at its throat with four slots 10 each in axial alignment with an obstacle 4 and each supplied with compressed air by a pipe 11 having an operative connection 13 with the appropriate rod 8. To deflect the jet, one or more obstacles 4, as indicated in the upper part of the Figure, are moved into the jet stream with consequent closing of the corresponding valve(s) 12. Since the valve 12 associated with the withdrawn obstacle is open (lower part of the Figure) a gaseous jet will flow along the adjacent part of the surface of the divergent extension 2 to ensure the adherence of the deflected jet, indicated by dotted-line 15. The valves 12 may be operated independently of the obstacles 4 in order that all obstacles may be moved within the jet pipe to vary the cross-sectional area of the jet. In a further embodiment (not shown) the arms 5 are tubular and terminate in hollow, slotted obstacles so that sheet-jets of compressed air may supplement the deflecting effect of the obstacles.
