摘要
FIELD: mechanical engineering.;SUBSTANCE: invention relates to control levers for angular setting of stator blades, compressor of turboshaft engine containing great number of stator blades with different angles of setting equipped with control levers, and turboshaft engine including said compressor. Stator blade angular setting control level consists of first end, second and flat middle part connected with first and second ends. First end is stationary installed on radial support of blade and it has thickness and width greater than that of middle part and second end of lever. Second end of lever has cylindrical pin for mounting on drive device. Shapes and sizes of middle part and second end are aimed at increasing own frequency of lever at bending and twisting over vibration frequency of section of turboshaft engine arranged higher than lever and preserving rigidity of lever.;EFFECT: prevention of development of breaks and cracks on lever without materially changing its rigidity.;10 cl, 3 dwg
