Abstract: 908,443. Helicopters. NAPIER & SON Ltd., D. March 10, 1960 [March 10, 1959], No. 8237/59. Class 4. Apparatus for controlling the power delivered to a rotor on a rotary wing aircraft from a power unit comprises a device arranged to operate synchronously with the rotor and controlling power control means to vary the power delivered to the rotor cyclically during each revolution thereof to reduce unwanted vibrations therein. In Fig. 1 the rotor head 1 is assumed to have four blades 2 driven by a shaft 3 through reduction gearing 4 from a gas turbine engine 5 having a fuel metering unit 6 of normal type, modified according to Fig. 2, wherein 9 represents the piston of a known type of fuel pump servo control device, which controls the output of the fuel pump in accordance with a fluid pressure signal from a speed governor unit 10. The modification comprises an extension 11 to piston 9, subject to the pressure in a chamber 11a. This is derived as a series of pulses from a pulse generator 7 which comprises an inlet passage 12 to which fuel is delivered by the fuel pump, a rotary interrupter disc 13 driven from rotor 1 through a shaft 14 so as to revolve at rotor speed and having holes 15 therein to correspond to the number of rotor blades so that each of the holes 15 in turn forms a communicating passage between passage 12 and a fluid return passage 16. Passage 12 communicates with chamber 11a through a conduit 8 formed with an adjustable restriction 18 which adjusts the amplitude of the pulses to the cyclic variation of load in the rotor head. In the alternative arrangement shown in the drawing accompanying the Complete Specification the adjustable restriction 18 in the pulse generator 7 is controlled through rod 28 of a servo device 23 having a piston 27 influenced by differential pressures in a fuel supply system. A linkage 20 from blade pitch control mechanism adjusts a variable control orifice 21 in a pipe line 22 leading from a fuel metering device 6 to one side of servo device 23. Fuel is supplied to the other side of the device from an engine torque meter 4 through line 24, the outlet from device 23 being through fixed orifices 25 and a return line 26 to fuel metering unit 6.
