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.
A bladed rotor including a hub and adjustable blades carried by the hub, said hub including, housed wholly therein in close proximity to each other and rotatable all as one therewith, (a) structure defining a liquid reservoir of annular form which, during rotation of the rotor, is independent of anY liquid supply source external of said rotor, (b) a single liquid-pressure-operable vane-type actuator which is disposed with its axis of rotation coincident with the axis of rotation of the rotor, which is connected to said blades for effecting adjustment the...
