FIELD: aviation technology.
SUBSTANCE: invention relates to aviation technology. Medium-haul aircraft contains a fuselage with a pressurized cockpit with a cockpit canopy and a passenger compartment or a cargo compartment, wings and tail unit with aerodynamic controls, turbofan engines, a tricycle retractable landing gear, fuel tanks, communication and control systems. At the same time, the aircraft fuselage creates 75% of the total aerodynamic lift force, is made in the form of a disk, has the shape of a disk flattened in the transverse direction and pointed in the nose with a flat bottom that is beveled towards the tail. In the forward part of the fuselage there is an on-board equipment compartment and a cockpit with a cockpit canopy, in the central part there is a passenger compartment or a compartment for cargo, then a fuel tank, and in the tail part there are two turbofan engines with outside air supply from air intakes located on top of the fuselage on the sides keel, to the engines through S-shaped channels. Low-lying delta wings of small span are installed on the sides of the fuselage in its tail section, aerodynamic controls include elevons and spoilers on the wings and a rudder on the keel, a three-post retractable landing gear is installed below the bottom, and winglets are installed at the ends of the wings.
EFFECT: significant increase in flight efficiency.
