HELICOPTER Russian patent published in 2019 - IPC B64C27/32 F04D29/36 

FIELD: aviation.

SUBSTANCE: invention relates to aviation, in particular to the design of the supporting systems of helicopters. Helicopter includes fuselage (1) with longitudinal axis (L) and rotor head (2), which is driven by means of rotor drive axis (A) which rotor head has at least two blades (6.1), secured by means of one rotor blade shaft (6) each. Rotor bearing axis (B) of the rotor blade shafts (6) is configured for displacement perpendicular to the direction of its length relative to rotor drive axis (A). Rotor axis (3) comprises a plurality of parts, said parts of rotor axis (3) include at least one bearing axis (3.1) and additional bearing axis (3.2). Rotor head (2) in at least one blade part (2.2) supports at least two blade shafts (6). Moving parts of axis (3), bearing axis (3.1) and additional rotor bearing axis (3.2) are designed to deflect oppositely, due to which blade shaft (6) and additional blade shaft (10) move in opposite directions relative to each other.

EFFECT: achieving higher flight speed.
