Abstract
601,566. Helicopters. UNITED AIRCRAFT CORPORATION. Dec. 7, 1945, No. 33125. Convention date, Feb. 2. [Class 4] A single-bladed sustaining rotor, shown in plan, Fig. 2, comprises a blade portion 18, a central portion 32 pivotally connected to a rotor head 38 to allow turning about longitudinal and transverse axes, and a counterbalance portion 34 carrying a weight 68 movable on a curved rod 66, as the blade cones upwardly or downwardly, to maintain itself in vertical alignment with the blade longitudinal axis; the blade also carries a weight 72, movable upon a transverse rod 74 to offset the effect of differences in drag upon the blade. Pilot-controlled means are used to vary the pitch of the blade cyclically, the angular movement of the blade, as the pitch is changed, acting through a linkage to move weight 72 outwardly from the rotor head during increase of pitch and allowing spring 75 to return it during decrease of pitch. The blade-driving shaft may be flexible and mounted in vibration dampers.
