ABSTRACT:
A gas turbine vane generally comprises an outer hollow vane member provided with a plurality of ribs aligned on the inner wall of the outer vane member and an insertion member of vane shape inserted into the outer hollow vane member so as to rigidly engage with the ribs. A turbulence chamber is defined between the leading edge portions of the outer and inner vane members, and the inner hollow insertion member is provided with numerous orifices at its leading edge portion for injecting cooling fluid into this turbulence chamber. A plurality of cooling passages operatively connected to the turbulence chamber are formed between the flank walls of the outer and inner vane members, and a plurality of orifices are further provided through the flank walls of the inner insertion member so as to communicate the interior thereof with the cooling passages.
