Abstract

880,606. Aircraft. BOLLS-ROYCE Ltd. Nov. 12, 1959 [Nov. 21, 1958], No. 37556/58. Class 4. [Also in Group XXVI] An aircraft has a pair of turbine driven fan units disposed on opposite sides of the longitudinal axis of the aircraft and having their outputs substantially vertically directed, and fan unit control means such that when the output of one fan unit is increased, that of the other is decreased. Fig. 1, is an underneath plan of an aircraft having jet propulsion engines 1 and banks of vertical lift jet engines 2, 3. Turbine driven fans 4, 5, 6, 7, 8, 9 discharge vertically downwardly. The controls of fans 4 and 6 are connected so that the ratio of their outputs can be varied while their combined output remains constant, and the pairs of fans 5 and 8, 6 and 8, and 7 and 9, are similarly connected. The pair 4 and 6, or 5 and 8, are used for pitch control, and the pair 6 and 8, or 7 and 9, for roll control. Motive fluid for the fan-driving turbines may be taken from the compressor or exhaust of gas turbine power plant on the aircraft. A part section of a fan is shown in Fig. 2, the turbine motive fluid being ducted to a manifold 10 discharging through guide vanes 11 on to turbine blades 12 at the tips of fan blades 13. Fixed guide vanes 15, 16 are provided for the fan air. The output of the fan can be varied by butterfly valves 17 controlling the passages between consecutive guide vanes 11. Half the valves 17 are controlled by a cam ring 18, and half by a cam ring 19. The valves may control only alternate passages between the guide vanes 11. Alternatively, the fan output may be variable by varying the inclination of the vanes 11, half the vanes being controlled by each cam ring.
