Zusammenfassung: | FIELD: axial-flow microturbines. SUBSTANCE: blade has widening-narrowing profile with trailing and leading edges defined by arc of circle, convex and concave sides defined by parabolic arc. Chord of blade profile is equal to 1.7-2.4 of its width. Ratio of maximum thickness of profile to chord ranges from 0.13 to 0.17. Distance between leading edge of profile and center of maximum thickness ranges from 0.05 to 0.1. EFFECT: increased torque at turbine output shaft in all modes of operation at subsonic, transonic and supersonic speeds. 2 dwgg |
