Patent ID: 7326035

Claim:
An attachment device for attaching a blade to a turbine rotor disk in a turbomachine, the blade root being engaged axially in a slot of the rotor disk, the blade root and the slot having a substantially longitudinal orientation and having complementary shapes for holding the blade onto the disk, the device comprising means for preventing the blade root from moving axially in the slot, wherein at rest and under uniform temperature conditions, the axis of the blade is inclined upstream or downstream relative to a plane perpendicular to the axis of rotation of the rotor, in a direction and at an angle that are configured to compensate at least in part for the displacement of the axis of the blade resulting from the deformation of the blade that is caused by the mechanical and thermal stresses applied to the rotor during operation of the turbomachine so that the axis of the blade is substantially perpendicular to the axis of rotation during operation of the turbomachine.
