摘要

FIELD: engines and pumps. ^ SUBSTANCE: adjustable vane has central part divided by geometrical lines into four adjacent inner zones arranged along vane inner side and into four adjoining outer zones located along vane outer side. Sinner and outer zones are located on both sides of vane profile concave line. Vane central part has independent inner and outer cooling circuits. Inner cooling circuit comprises three radial cavities occupying the adjoining inner zones. Outer cooling circuit has three radial cavities occupying four outer zones and one inner zone. ^ EFFECT: higher efficiency of cooling and vane production. ^ 12 cl, 7 dwg
