ABSTRACT:
A rotor blade for a gas turbine engine is provided with an internal tip damper comprising a damper weight which rotates under centrifugal load to cam itself into engagement between two components of the aerofoil, in particular the interior surface of the hollow aerofoil and the tip of a cooling air entry tube. By altering the degree of offset between the center of gravity of the weight and its support the frictional engagement may be varied.
