Abstract

1476402 Aircraft tactile warning devices J M MARIS 23 May 1975 [4 June 1974] 24738/74 Headings B7G and B7W A control stick 1 has a handle 2 within which is incorporated an out-of-balance motor 3 and a control switch button 9, the motor being energized by a stall-detecting device to vibrate the handle. The stall detecting device, e.g. an aerodynamic vane, not shown, closes a normallyopen switch 6 which is in circuit from a battery 7, with a normally closed switch 4, a motor 3, a time delay 7A provided to eliminate spurious signals caused by wind gusts disturbing the aerodynamic vane, and a warning horn 5. A switch 8, in parallel with switch 6, may be closed manually to test the circuit. The button 9 may be operated to open switch 4 to disarm the circuit. The motor 3 may be rendered unbalanced by attaching an out-of-balance weight to its rotor, and the mounting of the motor within the handle comprises a rigid mounting 10 in a tube 11 formed with a flange 13 clamped between a hard rubber support 14 and a screwed plug 15. The outer end of tube 11 is closed by a plug 16 which houses button 9, and a removable plate 18 provides access to wiring 17.
