REINFORCEMENT AND COOLING STRUCTURE OF A TURBINE BLADE

摘要

The invention relates to a blade (13, 14) for a turbine (10) which has at least one channel (22) that can be impinged with a coolant fluid. Several turbulators (23) which improve the heat exchange between the wall (19, 20) and the coolant fluid are provided on at least one wall (19, 20) of the channel (22). In addition, the turbulators (23) reinforce the wall (19; 20) and converge. As a result of said reinforcement, the thickness (d) of the wall (19, 20) in the area between the turbulators (23) can be reduced.
