Abstract

988,089. Gyroscopic apparatus. ELLIOTT BROS. (LONDON) Ltd. June 13, 1962 [June 15, 1961], No. 21749/61. Heading G1C. A stable platform for inertial navigation systems comprises three or more stable elements, as shown four stable elements 6 are provided, rotatable about individual azimuth axes and mounted in a phase normal to these axes symmetrically round a centre on a frame 4 supported from the centre by mechanism allowing the desired roll and pitch freedom of the frame 4, and itself carried by an arm 2 of a supporting structure. The stable elements 6, on which gyroscopes and other sensing units are mounted, are arranged partly within the channel of frame 4 which is of C, U, V or horseshoe shape so that supporting arm 2 may protrude through the gap in the frame 4. The shaft 10 forming the outer roll axis is journalled in arm 2 and carries, Fig. 2, a short pitch axle 13 to which a forked head 12 is pivotally secured, the inner roll axis being formed by shaft 11 connected between head 12 and frame 4. In a modification, Fig. 5, the shaft 10 is pivotally connected to a gimbal ring 16 through a short cross axle 17 which comes into use as a supplementary roll axis if the vehicle carrying the platform is pointed approximately vertically upward or downward. The gimbal ring 16 has extensions 18 journalled in frame 4 to form a pitch axis. In a modification in which there are only three axes instead of four, shaft 10 is connected directly to the middle of a single cross shaft corresponding to extensions 18. The spindles 9, supporting the stable elements 6 on frame 4, are connected by equal-length arms 8 to a C-shaped link 7 so that the arms 8 are always identically directed.
