A bladed rotor assembly comprises a bladed rotor and a rotor housing. The bladed rotor has a plurality of blades arranged in a circumferential array around an axis of rotation, and the rotor housing encircles the bladed rotor and has a radially inwardly facing surface.;Each of the blades comprises a first, radially extending, edge, a second opposite, radially extending, edge, and a radially distal edge. The radially distal edge has a first end, a second end, and a centre portion, with the first end adjoining the first, radially extending, edge, and the second end adjoining the second, radially extending, edge.;A clearance between the radially distal edge and the radially inwardly facing surface is a first clearance at the first end, and decreases to a second clearance across the centre portion. |
