1,158,258. Rocket thrust deflection. BOLKOW G.m.b.H. 8 Dec., 1966 [10 Dec., 1965], No. 54941/66. Heading B7G. A guided missile has remotely controlled means for deflecting the jet efflux from a propulsion engine, e.g. a rocket motor, the angle of deflection being limited by the static pressure in the combustion chamber of the rocket motor. The jet may be deflected either by a spoiler 6 intercepting the jet downstream of the nozzle 5 or by a tiltable nozzle 5SP1/SP. The deflection may be caused by an electromagnet 3, 3SP1/SP attracting an armature in a lever arm 2, 23, causing this to turn about a pivot 18, whence the arm returns due to the pull either of another electromagnet 4 or a spring 25. In Fig. 1 the angle of jet deflection is limited by the insertion of a spacer 1 when the rocket combustion chamber pressure is high. In Fig. 6 the angle of jet deflection is limited by the electromagnet 3SP1/SP being mounted on a plate 17 which can be turned about pivot 18 by a bellows 13, inflated with the combustion chamber internal pressure, compressing another spring 20SP1/SP.
