Abstract
1,175,066. Boundary layer control. WESTLAND AIRCRAFT Ltd. 6 Dec., 1967 [12 Dec., 1966], No. 55651/66. Heading F2R. [Also in Division B7] A convertible rotorcraft having one or more lift rotors movable from a vertical thrust position to a horizontal thrust position and having a tiltable wing, has its rotor(s) powered by a gas turbine 13, 21, 22 from which gas may be bled (e.g. via a valve 12) for boundary layer control of at least part of the tiltable wing. The valve 12 may be controlled by a computer 11 so that boundary layer control gas is only supplied during a transition between horizontal and vertical flight, the computer also controlling the fuel supply to the turbine. The computer may receive signals corresponding to engine temperature (sensor 19), free turbine speed (sensor 20) desired rotor speed (lever 17), engine power (dependent on rotor collective pitch controlled at 18), and from a selection lever 10 which has two positions, one for transition and the other for cruise.
