Abstract

634,339. Helicopters. AUTOGIRO CO. OF AMERICA. Aug. 8, 1947, No. 21890. Convention date, March 24, 1942. [Class 4] In helicopter aircraft of the type on which an airscrew is mounted transversely offset from the rotor axis for effecting translational flight and for balancing the rotational effects of the rotor on the fuselage, the anti-rotational effect, which decreases with an increase in forward speed, is augmented by mounting on one extremity of the tailplane furthest from the airscrew an adjustable cambered fin. The incidence of fin 7, pivoted at 8, may be pre-set on the ground or pilot-controlled in flight and the surface is cambered to produce a moment about the rotor axis tending to augment theanti-rotational effect of airscrew 3, within the slipstream of which is located a fixed fin 5 and a controllable rudder 6. Specification 393,976 is referred to.
