Abstract

1,118,117. Controlling helicopters. DORNIER-WERKE G.m.b.H. 22 April, 1966 [22 April, 1965], No. 17706/66. Headings B7G and B7W. A helicopter has a tail mounted screw propeller rotatable about a longitudinal axis to produce forward thrust and provided with cyclic pitch control for yaw control. The propeller blades 12 are pivotally mounted, preferably by the hub which forms part of a constant velocity joint (Fig. 4, not shown) and is tilted by movement of a swashplate 13. The cyclic pitch variations thus change the plane of rotation of the blades, and the thrust direction (Figs. 3a, 3b, not shown). The pilot's rudder bar 16 operates the cyclic control and a rudder 22 immediately upstream of the propeller through a mixing unit 20 which varies the control movements applied to the rudder and swashplate in accordance with ram air pressure (i.e. forward speed), so that at cruising speed only the rudder is operated, but when hovering, both rudder and swashplate are operated. The mixing unit may additionally be controlled manually. The main rotor and tail propeller are driven by a gas turbine engine (2, Fig. 1, not shown), through a gear-box (3) with separate output shafts. Collective pitch control of the main rotor and the tail propeller are effected together by a pilot's control lever 23 and in the same sense. The collective pitch of the tail propeller may be increased automatically as the cyclic pitch increases to provide a sufficient range of yawing moment, and may also be varied independently by an electric motor 28 operated by a button 30 on the control column 29, to preserve an efficient balance between the forward thrusts produced by the main rotor and tail propeller. An instrument 31 indicates when a certain forward position of the column 29 has been reached. Control surfaces, wings.-A tailplane (8, Fig. 1, not shown) is located in the downwash of the main rotor; this is stated to prevent a sudden trim change as the helicopter accelerates from hovering flight. The helicopter is also supported during forward flight on wings (7), the lift of which can be varied by spoilers or flaps or by varying their incidence, e.g. so that sufficient body incidence can be attained to cause autorotation of the main rotor in the event of engine failure.
