【摘 要】This clearly indicates that the overall loss can be most easily reduced by reducing the profile loss throughout the entire turbine. The secondary flow loss is of significance for those stages that are characterized by a low aspect ratio ( ratio of blade height to blade chord), i. e. the front stages of the HP and IP turbine component. Leakage los- ses are relatively high in the admission sections to the HP and IP turbines
