Abstract
An adaptor assembly for coupling a blade root of a turbine blade to a root slot of a rotor disk is described. The adaptor assembly includes a turbine blade having a blade root and an adaptor body having an adaptor root. The adaptor body defines a slot having an open end configured to receive the blade root of the turbine blade such that the adaptor root of the adaptor body and the blade root of the turbine blade are adjacent to one another when the blade root of the turbine blade is positioned within the slot. Both the adaptor root of the adaptor body and the blade root of the turbine blade are configured to be received within the root slot of the rotor disk.

An adaptor assembly for coupling a blade root of a turbine blade to a root slot of a rotor disk, the adaptor assembly comprising:
- a turbine blade comprising a blade root;
- and
- an adaptor body comprising an adaptor root, the adaptor body defining a slot having an open end configured to receive the blade root of the turbine blade such that the adaptor root of the adaptor body and the blade root of the turbine blade are adjacent to one another when the blade root of the turbine blade is positioned within the slot and both the adaptor root of the adaptor body and the blade root of the turbine blade are configured to be received within the root slot of the rotor disk.
An gas turbine rotor system comprising:
- a rotor disk comprising a root slot;
- a turbine blade comprising a blade root;
- and
- an adaptor assembly comprising an adaptor root, the adaptor assembly defining a slot having an open end in which the blade root of the turbine blade is positioned such that the adaptor root of the adaptor body and the blade root of the turbine blade are adjacent to one another, wherein both the adaptor root of the adaptor body and the blade root of the turbine blade are positioned within the root slot of the rotor disk.
