Abstract

809,947. Aircraft. COOKE, W. D. Nov. 30, 1956 [March 27, 1956], No. 9519/56. Class 4. A helicopter rotor assembly includes a series of aerofoil blades mounted to rotate about an axis in a flow of gas delivered by a centrifugal fan coaxial with the blades and arranged to rotate in the opposite direction to the blades. In Fig. 2, an aircraft fuselage 19 has a forwardly facing air intake 20 leading to the centrifugal fan 13 rotated through gears 15, 14, 8 and 9 by a motor 11. Blades 1 in the spiral air flow from the fan are rotated by the motor 11 through gears 4, 5, 6, 8 and 9, and the air is finally discharged through an aperture 21 in the fuselage. The blades are inclined to the radial direction to meet the air flow streamlines at right angles. Fig. 5 shows a flying crane comprising a dome 15 with a central aperture 26 leading to a gas turbine unit 20 pivotally mounted on the dome about two axes at right angles so as to be universally orientatble by electric motors 27, 28 controlled from the ground through a cable 29, or by radio control. A fuel tank 31 is mounted in the gas turbine unit. The turbine exhaust passes into a centrifugal fan 36 rotated by the turbine, and thence over aerofoil blades 39 mounted on a member 40 rotated in the opposite direction to the blades through stationary planet gears 41a. A hook 45 on the dome supports the load, and the apparatus is stabilized by jet reaction from two vertical nozzles 48 (one shown) mounted on forwardly and laterally extending arms 46 (one shown). The jets are controlled by pendulum operated switches, Fig. 8 (not shown), and supplied from the gasturbine compressor. Fig. 11 shows a cross section of part of the wing of an aircraft. The centrifugal fan 82 and blade assembly 83 are rotated in opposite directions by a motor in the fuselage which also drives a propeller. The intake aperture 94 can be closed for conventional fixed wing flight by a spanwise sliding panel 95, and the discharge apertures 98 can be closed by flexible panels 99, 100 guided by rollers 101, 102, 104, 105, the panels being operated by reversible electric motors. The direction of discharge of air can be controlled by vanes 106, 108 and 109. Outboard of the fan and blades, the wing is of reduced chord and thickness.
