AIRCRAFT FOR TRANSPORTATION OF LARGE-SIZED CARGOES Russian patent published in 2020 - IPC B64C29/00 B64C27/22 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, particularly to the rotorcrafts designs. Aircraft for transportation of large-size cargo consists of fuselage, cabin, power plant of two turbojet engines GTE-25 V, two turbojet traction engines CF34-8E, two coaxial rotors with blades (6), having the possibility of changing angle of attack. Blades are reinforced with frames (7). Farms (7) together with blades (6) are fixed to the lower and upper drums (21, 24). Rotation torque is transmitted to drums (21, 24) via reduction gear from engines (3). Drums (21, 24) rotate in different directions. All massive rotating parts are located on one axis, which is bearing pipe (17). For control is fan 5 with varying position of blades. Two coaxial rotors with blades (6) create only lifting force of aircraft. Two turbojet traction motors (4) serve to create a horizontal thrust of the aircraft.

EFFECT: higher lifting force, reduced bending moment acting on rotor blades.
