Turbine blade for gas turbine engine, has set of cooling channels extending between foot section and tip section of blade leaf, where channels are positioned in curve line pattern and each channel passes to tip section

摘要

The blade has a blade leaf (40) with a foot section (84), a tip section (86), a blade leaf shape and a profile corresponding to Cartesian coordinate values, where one of the values (Z) is a distance from a platform (42) and the other values define the profile in the distance (Z) to the platform. The blade leaf extends outwards from the platform. A set of cooling channels (54) extends between the foot section and the tip section of the blade leaf, where each cooling channel passes to the tip section. The channels are positioned in a curve line pattern.
