TURBINE VANE ARRANGEMENT

摘要

The present invention relates to a guide vane arrangement (100) for a gas turbine and to a method of manufacturing a guide vane arrangement of a gas turbine. The guide vane arrangement (100) comprises a first guide vane device (110) comprising a first number of first airfoils (111) and a second guide vane device (120) comprising a second number of second airfoils (121). The first guide vane device (110) and the second guide vane device (120) are arranged along a circumferential direction (102) of the turbine, wherein the first number of the first airfoils (111) differs to the second number of the second airfoils (121). The first guide vane device (110) is designed with a higher heat resistance than the second guide vane device (120).
