Abstract

780,381. Wind motors. DE HAVILLAND PROPELLERS, Ltd., and PERDUE, R. J. Feb. 28, 1955 [March 1, 1954], No. 5989/54. Class 110 (3). [Also in Group XXXIV] Relates to an anemo-electric power plant comprising a wind-driven propeller with hollow blades apertured at their tips and which suck air through a turbine driving a generator. According to the invention, a head structure 6, Fig. 1, carrying the propeller 7 is rigidly secured to the top of a column 1 mounted for rotational movement in a bearing 2 intermediate its ends and a bearing 3 at ground level, the outlet of the air turbine 5 making an air-tight communication with an air inlet to the column, and the head structure or column having an air-tight passageway leading to the blades. The upper portion of the column is of elliptical crosssection and is provided with a stream-lined fairing 16 on the leeward side. It is inclined slightly to leeward and carries wind vanes 13 for orienting the column. The bearing 2 is supported by a tripod of tubular struts 4 and rotation is prevented by wire ropes 32 secured to lugs on opposite sides of the bearing. The bearing comprises a sleeve 18, Figs. 4 and 5, carrying trunnions 19 in which the upper ends of the struts 4 are engaged. The sleeve is provided with upper and lower channel-section housings 17 in each of which is arranged an annular series of rollers 29 arranged in pairs between parallel plates 28 constituting parts of rocking arms 27 carried by spindles 21 eccentrically mounted in the housing 17. Roller tracks 30 are secured by flanges 31 to the column and the spindles 21 are adjusted to bring the rollers into engagement with the tracks and are then locked in position by means of nuts 26. The weight of the column is taken by a thrust bearing 33, Fig. 6. Yawing of the column is damped by a device comprising interleaved fixed and movable friction plates 40 loaded by an annular member 41. The load is constituted by the differential pressure on a disc 43 which is transmitted through a plunger 48 carried thereby and connected through links 49, 51 to the member 41. The disc is connected to the column by a diaphragm 42 and is subjected on opposite sides to the pressures at the inlet and outlet of the turbine respectively.
