The blading (10) has rotating vanes exhibiting split ratio of blade pitch and chord length (t/l) in a pointed-near section, where the split ratio amounts to 0.95. The rotating vanes exhibit an exit angle that amounts to 160 degree and an acceleration ratio that amounts to 1.5. The rotating vanes are formed as solid vanes and hollow vanes. The rotating vanes exhibit maximum profile thickness (d max) of 2 mm in the pointed-near section. Guide vanes exhibit maximum profile thickness of 9 mm in the pointed-near section. The acceleration ratio amounts to 1.5 in a foot-near section.
