ABSTRACT:
A turbine blade (20) has cooling air passageways (30) and (30a,30b,30c.) through the leading edge wall portion (24) which are positionally arranged so as to intersect each other within the wall thickness so as to transmit mechanical stresses into the thicker, non-perforated material of the blade aerofoil (22). Further passageways near the blade root portion (42) do not intersect, the reduced cooling in that area causes expansion and stress absorption.
