F01D11/18 - CPC Classification

Classification description:

Preventing or minimising internal leakage of working-fluid, e.g. between stages for sealing space between rotor blade tips and stator; Adjusting or regulating tip-clearance, i.e. distance between rotor-blade tips and stator casing by self-adjusting means using stator or rotor components with predetermined thermal response, e.g. selective insulation, thermal inertia, differential expansion
