Abstract (en)
The present invention relates to an aerofoil (10) and a method for construction of the aerofoil (10). The aerofoil (10) comprises an outer wall (20) and an inner wall (30), wherein the walls (20,30) are separated by a cooling channel (40), and a coolant fluid (60) is guidable through the cooling channel (40) during the operation of the aerofoil (10). The inner wall (30) is provided with a protrusion (70), which is profiled and arranged such that it extends from the inner wall (30) into the cooling channel (40). The protrusion (70) directs at least a part of the coolant fluid (60) to impinge the coolant fluid (60) on a first region (64) of the outer wall (20).
