Recently, from the environmental point of view, demand for a combined cycle plant is increasing, and superior gas turbine performance is being rapidly promoted at the same time. As one of the key technologies for superior performance, reduction of secondary air leakage, which is necessary for blade cooling and bearing sealing, is required. Especially, reduction of air leakage through rotating parts and stationary parts clearance is critical.
