FIELD: engines and pumps. ^ SUBSTANCE: invention relates to machine building, particularly to aircraft engine production and can be used in aircraft engines to increase thrust and facilitate evolution in flight. Proposed outlet device comprises shell, central body made up of stationary main part, flaps and flaps control mechanism. Outer duct is arranged between main part and shell. Flaps are arranged on central body to shut off outer duct. Flaps control mechanism comprises tie rods, each with its one end hinged inside central body to axially move therein and with its other end hinged to flap. One end of the flap is hinged to central body main part. Outlet device flaps comprises two tiers, outer and inner, with cross sections increasing along the flow. Flaps inner tier has angular cross and outer section has segment-like cross section. Sides of inner tire angular flaps have chamfers for flaps to come in contact with and along them. Flaps outer tier contacts inner tier along the sides of adjacent flaps. Tie rods are coupled with flaps inner tier. ^ EFFECT: higher efficiency of turbine outlet due to reduced gas leak between outlet flaps. ^ 2 dwg |
