Abstract
The blades of a turbomachine comprise airfoils, which are bent such that the lean angle (φ), defined as the angle which the stacking line of the airfoil includes with the radial direction, and measured in the direction of rotation (ω), is variable along the width of the flow channel and decreases from the hub towards the housing.
