TURBINE BLADE WITH PERFECTED AERODYNAMIC CHARACTERISTIC AND TURBINE WHEEL WITH SUCH BLADE

摘要

FIELD: engines and pumps.;SUBSTANCE: turbine wheel and rotor blade has pressure side surface (19) and rarefaction side surface (21). Rarefaction side is smooth at its larger portion except for some bulges (25). Bulges are distributed nearby and along rear edge (17). Pressure side surface is smooth.;EFFECT: smaller separation zone nearby blade surface charged with disturbances influencing the turbine efficiency.;12 cl, 4 dwg
