ABSTRACT:
The pre-load device for a turbomachine rotor according to the invention has a shank formed of a superplastic material which is axially insertable in a shank bore formed between confronting notches formed on a rotor disk and a blade root portion. In one embodiment, the notches extend generally parallel to the longitudinal axis of rotation of the rotor disk. The shank defines an interior chamber in which is located a low-melting point material. An electrical resistance heating element is located in the low-melting point material and has means to be connected to an electrical source. The device also includes headed portions attached to each end of the shank, each of the headed portions bearing against axially facing surfaces of the rotor disk and the blade root so that, when the head means are attached, relative axial movement between the elements is prevented. In another embodiment, the notches extend generally transverse to the longitudinal axis of rotation in a projection on the rotor disk and a mounting groove in the blade root portion.
