Abstract
Official abstract text for this publication.
A concave (a relief portion) is formed along a circumferential direction of a rotor in a trailing-edge end surface of a platform. In the trailing-edge end surface disposed outside of the relief portion in the radial direction of the rotor an opening of a cooling channel is provided. The end surface is formed thicker in the radial direction of the rotor at the opening of the cooling channel than at a position corresponding to a trailing-edge end of a hub of an airfoil portion connected to the platform.
First claim
Opening claim text (preview).
The invention claimed is: 1. A turbine blade comprising: a base portion which is fixed to a rotor; an aerofoil portion which extends in a radial direction of the rotor and which includes a blade surface on a pressure side and a suction side, the blade surface on the pressure side and the suction side forming an aerofoil profile between a leading edge and a trailing edge; and a platform which is provided between the base portion and the aerofoil portion, and which has a concave…
