<p>The blade has a gap (10) formed between an end of the blade and a main flow path confinement that is formed by a hub (2) or a casing (1). A skeleton line camber distribution unit having an excessive value of a relative skeleton line camber of 0.35 for a related running length of 0.1, is provided in a blade profile flow line section in an area between the gap and a blade section at a distance of 30 percentages of main flow path width (W) from the gap. The skeleton line camber distribution unit commences at a leading edge point and terminates at a trailing edge point.</p> |
