Abstract: A gas turbine engine exhaust nozzle comprises a nozzle body defining a nozzle exit. An array of movable slats is disposed round the nozzle exit. Flow control walls are fixed to the nozzle body and provide flow control surfaces over which the movable slats move. The flow control walls prevent leakage of gas at the edges of the movable slats, so improving performance of the exhaust nozzle.

Abstract: A rotor blade comprising a core blade section; and a trailing edge section, the trailing edge section being attached to the core blade section along a join interface. The trailing edge section comprises a shape memory material which is actuable so as to cause selective deformation of the trailing edge section between a first condition in which a trailing edge of the trailing edge section follows a substantially smooth profile and a second condition in which the trailing edge is perturbed. The direction of the perturbation may be oblique or perpendicular to the direction of flow over the blade in use. The rotor blade may be a fan or propeller for a gas turbine engine.
