Abstract
A blade grid of a turbo-machine has at its inner surfaces of the inner and the outer bands not less than two rows of depressions, those are arranged in a horseshoe shape in chess order, ratio of the depth H of the depressions to the diameters D of those is within 0,5 > H/D > 0,1, and distance between the centers of the depressions in the row h1 is (2,0...2,5)D, and between the centers of the depressions in the rows h2-(2,5...3,0)D, at that the back ends of the depressions of the last row in flow direction are arranged at distance 0,025...0,050 of the blade chord in arc near the angular length 50...60 DEGREE DEGREE , with connection to the straight line going through the point of the minimal compression at the back side of the blade, at separation from the inlet edge of the blades by 0,3...0,4 of the blade chord.
