What will be the normal shaft centreline movement for Overhung Rotor supported by tilting pad bearings? Particularly with reference to a light overhung rotor, like Power Turbine Shaft in twin-shaft gas turbine driving heavier centrifugal compressor rotor.
I have attached shaft centreline movements for 2 different set of machines. In one case, power turbine is driving LP and HP rotors.
In another case, Power turbine is driving only 1 HP Rotor.
