ABSTRACT:
An aerofoil assembly includes a plurality of rotatable blades. A damping member is disposed between at least two of the blades, each of the at least two blades having an aerofoil portion, a stem portion and a root portion. A recess is provided on two cooperating stem portions with a first shelf extending from a first end of each recess, and a second shelf extending from a second end of each recess to define a compartment. When the blades are aligned the damping member is held on one side of the shelves within the compartment. The damping member is provided with a projection at one corner and a projection on a diagonally opposite corner, the longitudinal distance between ends of the projections being greater than the distance between edges of the first and second shelf.
