1,262,414. Deflecting propulsion jets. MESSERSCHMITT-BOLKOW-BLOHM G.m.b.H. 15 June, 1970. [23 June, 1969], No. 28977/70. Heading B7G. A jet deflecting device for controlling an aircraft comprises a truncated spherical nozzle having peripheral openings 2 on the pitch and yaw axes and a co-operating vectoring nozzle 3 also having similarly disposed openings and rotatable on the first nozzle such that on vectoring the nozzle 3, a larger aperture is presented by the openings for the passage of exhaust gases on the side towards which the nozzle is vectored than on the opposite side. In normal flight with clam shell doors 5 open, (Fig. 1, not shown), the openings act as ejectors by inducing ambient air into the gas stream, movement of nozzle 3 vectoring the jet thrust, but when the doors 5 close off the throat as shown, thrust reversal occurs, the vectoring of the nozzle then controlling the direction of thrust through the nozzle openings. Vanes 6, 7 adjustable by pilot or automatic control may be provided in the openings for the further directional control of exhaust gas efflux. |
