摘要： A sealing member that seals a core printout hole in a turbine blade of a combustion gas turbine engine includes a plug member and first and second leg members. The plug member is formed generally in a top hat configuration and is disposed in a cavity formed in the blade, the plug member being retained in the desired sealing position by the leg members. The plug member broadly serves the purpose of sealing the hole that is in communication with the cavity. The plug member includes a substantially planar plate that is disposed adjacent the internal first surface of a wall of the turbine blade and a retention member that is received in the hole. The first and second leg members are fixedly mounted, such as by welding, on the plug member and are at least partially disposed adjacent and overlap a second opposite and external surface of the wall.
