TURBINE BLADE

PROBLEM TO BE SOLVED: To provide a turbine blade allowing cooling air to sufficiently flow onto an end wall surface in the rear area of the trailing edge of the blade without increasing cooling air volume. SOLUTION: An end wall 3 includes a guide 6 provided in a position on the belly side of the tra...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbine blade allowing cooling air to sufficiently flow onto an end wall surface in the rear area of the trailing edge of the blade without increasing cooling air volume. SOLUTION: An end wall 3 includes a guide 6 provided in a position on the belly side of the trailing edge of the blade 2 and guiding the cooling air 11w led to flow out of a cooling hole 3h to the rear area of the trailing edge of the blade 2. The guide 6 has a leading end positioned forward of the trailing edge of the blade 2 and a trailing end positioned rearward of the trailing edge of the blade 2. At least one cooling hole 3h is arranged in an axial position between the guide 6 and the blade 2 and from the leading end of the guide 6 to the trailing edge of the blade 2.
