  • Tip structure for a cooled turbine rotor blade
    Patent number: 4606701
    Abstract: The invention comprises a cooled turbine rotor blade having an improved blade tip structure. A groove is provided in the trailing edge end of the blade tip on those turbine blades whose trailing edge is too thin to support an extension of the blade walls to form a blade tip cavity which extends to the tip of the trailing edge of the blade. The groove protects adjoining exhaust apertures from closure by a blade tip smear.
    Type: Grant

  • Tip structure for cooled turbine rotor blade
    Patent number: 4424001
    Abstract: The invention comprises a cooled turbine rotor blade having an improved blade tip structure. A recessed tip is provided at the leading edge end of the blade tip on downstream turbine blades which are too narrow to support a blade tip cavity over the entire exterior surface of the blade tip without interfering with cooling airflow from apertures in the exterior surface. The recessed tip structure protects apertures therein from blockage by a blade tip smear and does not substantially reduce the performance efficiency of the blade.
