FIELD: transport.
SUBSTANCE: invention relates to rotorcraft, namely, to VTOL aircraft. VTOL aircraft consists of wings actuator, cabin, engines and fan. Wings drive consists of four frames composed by guides of the wing pipe bearings, angle pieces and strips. Wings can generate air flow. Wings and pulleys are secured to toothed belts. Pulleys and levers for control over wing angle of attack are fitted on two shafts. Guide bearings allow levers welded to the left and right frames to run therein. There are two driven sprockets and guard sheet. Angle of attack of the wings does not vary at flight at straight section atop and at bottom. Wings can vary said angle of attack at flight in semicircle.
EFFECT: efficient vertical takeoff and landing, higher efficiency of power plant.
