Abstract
1487684 Fluid-pressure servomotor systems UNITED AIRCRAFT CORP 22 Jan 1975 [11 March 1974] 2815/75 Heading G3P An aircraft control system has input and output levers 18, 20 for a servo-control 10, and a link 24 which directly connects the input with the output if the servo control jams. The lever 18 provides follow-up control between the pilot valve 12 and power device 14 of the servo and both levers contain pins 38, 52 which shear when the servo-control jams so that the link 24 directly connects the input 16 with the output 22.
