Abstract:
A cut-back of a blade or vane in a gas turbine may comprise a first sidewall; a plurality of trailing ribs extended from the first sidewall and arranged along an end of the first sidewall; a second sidewall separated from the first sidewall, having a longer tail than the first sidewall and in contact with the plurality of trailing ribs; and one or more cut-back blocks extended between two trailing ribs along the inner surface of the second sidewall. The cut-back of the blade or vane may reduce the weight through the trailing ribs and the cut-back blocks formed at the trailing edge, and improve a heat transfer effect while retarding crack growth.

Claim (Index 1):
A blade of a gas turbine, comprising:\n a first sidewall constituting a pressure side of an airfoil; a second sidewall constituting a suction side of the airfoil, the second sidewall having a longer tail than the first sidewall, and the first sidewall and the second sidewall are separated from each other; a leading edge at which the first and second sidewalls meet each other; a trailing edge formed at the opposite side of the leading edge; a pillar-shaped fin extended between an inner surface of the first sidewall and an inner surface of the second sidewall in a region of the trailing edge; and a plurality of trailing ribs formed at a tail of the blade, wherein the plurality of trailing ribs are extended from an end of the first sidewall to the inner surface of the first sidewall and an end of the second sidewall, and the plurality of trailing ribs are separated from each other in a lengthwise direction of the trailing edge.
