Abstract (en)
[origin: EP2110559A2] The machine has a main flow path confined by a wall, and a row of blades e.g. rotor blades or stator vanes, fixedly mounted on the wall. A fluid intake opening (9) and fluid supply opening (10) are located in the wall in an area of the blades, where the openings are connected by a fluid return path (11). A circumferential extension of the supply opening is less than distance between two adjacent blades. One blade has a blade section with a profile camber comprising an angular difference of 35 degrees of tangents drawn on a profile skeleton line at leading and trailing edges of the blade.
