Abstract
A dovetail type circumferential slot fixing for retaining blades of a bladed rotor assembly of a turbomachine which requires no additional loading slot. The shape and dimensions of the dovetail roots of the blades and the dovetail blade-retaining slot are such as to allow the blades to be loaded by introducing a flank of each root dovetail into the slot and rolling the blades in an axial direction. The blades are held outwards against radially inward facing faces of the blade-retaining slot by a support means which may be a detachable plate, flange member or nose bullet that engages the blade platforms.
