Compressor Rotor Clause Samples

Compressor Rotor. The compressor rotor consists of a forward stub shaft with the 1st stage rotor blades, a fifteen blade and wheel assembly for stages 2 to 16, and an aft stub shaft with the stage 17 rotor blades. Rotor blades are inserted into broached slots located around the periphery of each wheel and wheel portion of the stub shaft. The rotor assembly is held together by fifteen axial bolts around the bolting circle. The wheels are positioned radially by a rabbeted fit near the center of the discs. Transmission of torque is accomplished by face friction at the bolting flange. Selective positioning of the wheels is made during assembly to reduce the rotor balance correction. The compressor rotor is dynamically balanced after assembly and again after the compressor and turbine rotors are mated. They are precision balanced prior to assembly into the stator.
