Abstract: A coolant feed arrangement for delivering coolant to an axially facing surface of a rotor disc configured for carrying a row of turbine blades on its radially outer surface, the coolant delivered through a conduit upstream of the rotor disc, which has an outlet arranged radially inwardly of the blades and directed at the axially facing surface, the arrangement including two or more impediments; at least one impediment including a work extractor device arranged in the conduit to extract work from the coolant on route to a last impediment arranged at or adjacent the outlet, the last impediment including a row of static nozzles configured for accelerating the flow of coolant circumferentially in the direction of rotation of the axially facing surface of the disc whereby to match the speed and direction of rotation of the axially facing surface as the coolant is delivered to the axially facing surface.
