1305747 Aircraft control system TEXTRON Inc 20 July 1970 [8 Aug 1969] 35085/70 Heading B7G An aircraft control system comprises a plurality of control surfaces 12, 14 and 16 controlled by pilot-controlled means, and a plurality of stabilizing surfaces 18, 20 and 22 controlled by actuators 60, 62 and 64 respectively which are responsive to signals from stabilizers 72, 74 and 76 which sense instability of the aircraft, and comparator means 92 which detects non-comformity of any of the actuators and causes the or each non-conforming actuator to be disabled. The comparator 92 may also detect and disable a non-conforming stabilizer. Disabling of any member is indicated to the pilot on the control panel. By non-conforming is meant that a member produces signals which differ from those from the other members, or which lie outside predetermined signal limits stored in the comparator. The actuators may be hydraulic or pneumatic servo mechanisms and the signals from the stabilizers, via lines 84, may be hydraulic or pneumatic, or may be electrical. A single stabilizing surface may be able to effect stability control; in the event of all the stabilizing surfaces being disabled flight control is effected by means of control surfaces 12, 14 and 16 which are under direct duplicated manual control. The control and stabilizing surfaces may be on an aircraft wing, or may for example be on the rotor of a helicopter. (For Figure see next page.) |
