845,142. Self-propelled missiles. SHORT BROS. & HARLAND Ltd. Feb. 2, 1959 [Feb. 25, 1958], No. 6050/58. Class 9(2). [Also in Group XXXIII]. Relates to a rocket propelled aerodyne, which may be a guided missile, having movable aerofoil surfaces for controlling the flight, the aerofoils being actuated through a servo-controlled fluid-pressure system responsive to radio signals received by apparatus housed in the aerodyne. According to the invention a device is provided in which gases generated by the rocket charge accumulate to build up a pressure, which pressure is transmitted to a supply line of hydraulic fluid connected through valves to the motors controlling the movements of the aerofoils. The missile, Fig. 1, has compartments 10, 11 housing the rocket motor and is provided with two pairs of mutually perpendicular wings, one pin B being shown. Each wing B has a stub axle 12 supported in bearings 13, 14 and from each axle projects an arm 15 with its free end located between opposed pistons 16, 17, Fig. 2, of a motor connected at opposite ends by ducts 181, 191 to a selector valve 20. The valve 20 is actuated by means of a rod 201 in response to movements of an armature 211 influenced by radio signals. Fluid enters the valve 20 from a supply pipe 22 connected to an oil reservoir 24 in a housing H, wherein a flexible diaphragm 25 separates the oil from a gas chamber 26. Gas from the rocket charge enters the chamber 26 through a non- return valve 28, when the pressure is sufficient to move a valve member 283 Fig. 3, to a position where openings 2831, 2811 register. Preferably the connection from the reservoir 24 to the supply line 22 is closed by a disc 222 adapted to rupture at a predetermined pressure. |
