Abstract

584,451. Radiolocation. HUGHES & SON, Ltd., H., SPROULE, D. O., and HUGHES, A. J. June 30, 1944, No. 12522. [Class 40 (v)] [Also in Group XXXIII] In a stabilised platform for supporting, in an aircraft &c., a reflector 1 of a radar scanning system, the reflector is pivoted in a bridle 2 so that it can be tilted about the horizontal axis 3 and the bridle is carried by a bracket 4 mounted on a shaft 4a driven by a motor 5 and carried by a carriage 6. The carriage 6 is adjustable on circular tracks 7, rollers 8 contacting a smooth part and pinions 9 engaging the racks 9a and driven through gearing by an electric motor 13a controlled from " roll " pick-offs of the vertical gyro 14 ; the centres of the tracks 7 are on a line parallel to the " roll " axis of the aircraft and pass through the centre of the reflector. The tracks 7 are connected to plates 15 adjustable on circular tracks 16, rollers 17 contacting a smooth part and pinions 18 engaging the racks 19 and, driven through gearing from the motor 24 controlled from the " pitch " pick-offs of the gyro 14 ; the centres of the tracks are on a line parallel to the " pitch " axis of the aircraft and pass through the centre of the reflector. The axis of the shaft 4a also passes through the centre of the reflector. A directional gyro 25 is provided to enable the angular rotation of the shaft 4a to be compared. Alternatively, the rollers 18 may be fixed to the aircraft and the tracks 7 may be carried by the carriage 6.
