SUPER-HEAVY THREE-SCREW MULTIPURPOSE HELICOPTER Russian patent published in 2019 - IPC B64C27/08 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly, to helicopters. Super-heavy three-screw multipurpose helicopter comprises three eight-bladed rotors operating from four high-power gas turbine engines. Rear rotors rotate from right to left and have diameters smaller than diameter of front rotor rotating from left to right. Helicopter has four freewheel clutches, main reduction gearbox, distribution box, three-barrel turret hydraulic monitor, two hydraulic capacities, four-column twelve wheel landing gear. Front landing gear wheels are self-orienting. Fuselage is made with process cavity for fuel tanks, right and left winches with worm reduction gearboxes. For heavy equipment transportation of hydraulic capacity is removed, and cargo floor is installed between central, fore and tail frames.

EFFECT: higher load-carrying capacity and increased safety of flight operation due to increased range of longitudinal alignment.
