  • Turbomachine blade
    Patent number: 8147205
    Abstract: The turbomachine blade has ribs formed in the vicinity of the trailing edge. Over the major fraction of the trailing edge (42), in zones where the temperature in operation is particularly high, the ends (53) of the ribs are closer to the trailing edge and/or the sections of the ribs (F) are greater. Thereby, the design of the blade is optimized and the lifetime thereof is increased.
