MULTI-PURPOSE DECK HELICOPTER AIRCRAFT Russian patent published in 2018 - IPC B64C27/24 B64C27/28 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, in particular to the construction of hybrid helicopters. Multipurpose deck aircraft-helicopter contains tilt rotors in the front ends of the beams, tail assembly, power units, which via drive shafts transmit power to the tilt rotors, which create horizontal and vertical thrust, corresponding to their deflection and a three-wheeled chassis with a bow auxiliary support. Multipurpose deck aircraft-helicopter is designed with a two-beam fixture of the U-shaped tail assembly, which has deflected keels inward to the plane of symmetry, and high-lying heterogeneous wings of the hollow circuit. Multipurpose deck aircraft-helicopter contains a transversely-bearing screw system, in which the left and right single-blade large rotor screws are mounted on the tips of the outer consoles of variable sweep, and vane-reversing rotary propellers propulsion system.

EFFECT: provides an increase in aerodynamic quality and maneuverability in transient maneuvers and at low flight speeds.
