Abstract: A rotor blade of a wind turbine, wherein the rotor blade includes a lift modifying device, is provided. The lift modifying device is a part of the trailing edge section of the rotor blade. The lift modifying device is configured such that, at a predetermined loading of the trailing edge section, an air channel opens up a flow path from the pressure side to the suction side and vice versa in the trailing edge section.

A method to modify the lift of a rotor blade of a wind turbine is also provided.

Abstract: A rotor stage (100) of a gas turbine engine (10) comprises a platform (120) from which rotor blades extend. The platform is provided with a circumferentially extending damper ring (200), the damper ring having an engagement surface (210) that engages with a platform engagement surface (110) of the platform (120).

This causes friction between the two surfaces, thereby dissipating energy and damping the excitation.
