BLADE FOR A TURBINE ENGINE AND METHOD FOR PRODUCTION OF SAID BLADE |
摘要 |
The blade has a two-part main body of titanium alloy, the two parts bonded together by a high temperature and high pressure connection. In the connection area (31), a groove (23) in the first part (11) has a wall (27) immediately next to the second part (13), to define a connection angle of more than 70 degrees . The alloy is titanium aluminide. The two parts form a common wall thickness within the connection area, which varies along the area. The first blade part forms the suction side, and the second part forms the pressure side. <??>The blade is formed as a gas turbine rotor blade, especially for the last turbine stage. |
