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.
