FIELD: aeronautical engineering. SUBSTANCE: intake unit includes propeller, propeller hub, engine nacelle outer fairing and engine air supply passage located behind propeller which includes several branch pipes located over periphery of fairing and projecting beyond its boundaries; branch pipes are provided with holes for discharge of foreign matter which are located above surface of fairing whose front diameter corresponds to diameter of propeller hub. EFFECT: improved aerodynamic characteristics of aircraft; increased power of engine due to increased pressure of air in air supply passage and reduced drag. 4 dwg
