FIELD: energy.
SUBSTANCE: invention relates to power engineering. Blade of a turbomachine containing a blade airfoil elongating in the axial direction between the front edge and the rear edge, and in the radial direction - between the root and the apex. Front edge of the blade airfoil has a sweep angle, which is positive and continuously increasing from the root to the first radial height of the blade airfoil located between 20 % and 40 % of total radial height of the blade airfoil measured from the root to the apex and continuously decreasing from the said first radial height of the blade airfoil to the apex. Invention also discloses a turbomachine and a turbomachine monowheel made as a whole.
EFFECT: invention enables optimum control over secondary air flows and also enables to consider penetration into the jet, which is called directed downward.
