发明名称 In-situ turbine blade tip repair
摘要 The tip portion of a blade of a gas turbine is repaired in-situ in the gas turbine without removing the blade from the turbine rotor disk. To facilitate the in-situ repair of the tip portion of the turbine blades, one or more access holes may be provided in the turbine shroud or blade outer air seal circumscribing the plurality of turbine blades extending radially outward from the turbine rotor dick.

主权项 1. A method for repairing a tip portion of a turbine blade of a gas turbine having a turbine rotor disk having a plurality of turbine blades and a turbine shroud circumscribing the turbine rotor disk, the method comprising the step of: providing at least one access opening in the turbine shroud, the at least one access opening having an airfoil shape; rebuilding the tip portion of the rotor blade in-situ without removing the blade form the turbine rotor disk; and providing a removable seal plug, having the airfoil shape, in the at least one access opening in the turbine shroud.
