FIELD: mechanical engineering.
SUBSTANCE: blade fastening unit of blade machine contains blades which are secured in rows on rotor or stator by roots. Proposed blades have root plate, band or support wing over root and feather. Band or support wing takes up twisting torque. After mounting of all blades of one row said blades abut with each other by root plates without clearance and thus relatively support each other against action of twisting torques. Twisting torques acting onto root plates are opposite to twisting torques acting onto band or support wing.
EFFECT: possibility of taking up twisting torques by blade root plate, relieving blade root and also rotor or stator from action of said torque.
