ABSTRACT:
A bladed rotor including a hub which carries, so as to be rotatable therewith, a liquid reservoir, at least one pump operable upon rotation of the rotor, a single liquid-pressure-operable vane-type actuator for adjusting the blades of the rotor to vary flow of fluid over the blades, and control valve means for controlling operation of the actuator. The said pump, when operating, draws liquid from the reservoir and delivers it under pressure, by way of said control valve means, to said actuator.
