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.
