Abstract

612,189. Rotary wing aircraft. CIERVA AUTOGIRO CO., Ltd., and PULLIN, C. G. May 17, 1946, No. 14943. [Class 4] A rotary wing system comprises lifting and driving components mounted on a common hub-member, the former comprising at least two aerofoil-shaped blades 17, and the latter two or more substantially non-lifting arms 18a, 18b, carrying aero-thermodynamic ducts 19a, 19b, at their tips. In the aircraft shown in Figs. 1 and 3 the arms 18a, 18b are connected to stub arms 21 on the hub 13 by drag pivots 20, and the lifting blades 17 are attached by drag pivots 16 to drag links 15 connected to the hub by flapping pivots 14. Fuel for the propulsive ducts is supplied by a pump 27 to a pipe 29 communicating with transfer pipes 39a, 39b inside the hub and flexible hoses 40a, 40b connected to ducts 41a, 41b inside the arms 18a, 18b. Cyclical and collective pitch control of the blades 17 is effected by a vertical member 44 passing through the hub 13, and mounted on a ball joint on a member 42 engaging the upper end of the hub. Cyclical pitch variation is obtained by rocking the member 44 by links 54, 60 and 55, 61, while collective pitch control results from vertical movement of the members 42, 44 initiated by links 62, 65. The movement of the member 42 relative to the hub is permitted by a pin-and-slot connection 51, 52. Fig. 6 shows a modification in which the rotor hub 31 is mounted on a ball joint 71 at the upper end of a central shaft 30, and the stub arms 21 carrying the driving arms 18a, 18b are attached to a ring 32 mounted on the hub by trunnions 66 whose axis is perpendicular to the driving arms. In this case the fuel pipe 29 is located on the axis of the hub and is connected to flexible hoses 69a, 69b in communication with ducts 70 in the driving arms 18a, 18b. The inclination of the rotor is adjusted by a non- rotating ring 33 which engages with the lower portion of the hub 31. Collective pitch control mechanism for the lifting blades 17 may be provided.
