CONVERTIPLANE AND CONTROL METHOD OF CONVERTIPLANE Russian patent published in 2020 - IPC B64C29/00 B64C27/28 B64C27/52 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly, to vertical take-off and landing of an aircraft. Convertiplane (1) comprises fuselage (2) with first axis (A), pair of semi-wings (3) and pair of screws (5) located at opposite ends of semi-wings (3). Screw (5) comprises shaft (6) hinged on second axis (B), and multiple blades (8), pivotally fixed on shaft (6). Shaft (6) of screw (5) can incline with second axis (B) relative to third axis (C) transverse to second axis (B), and relative to fuselage (2) for conversion of convertiplane (1) between helicopter mode and aircraft mode. Screw disc (10) can be inclined relative to fourth axis (G). Screw (5) comprises means (30) for control of cyclic pitch and general pitch of blades (8), comprising first actuator (21) controlled to vary common pitch, second actuator (51, 20) controlled to change the inclination of rotor disk (10) relative to the fourth axis (G) and rod (22) movable to change the inclination of the corresponding rotor disk (10) relative to the fifth axis (H) in accordance with mode convertiplane (1).

EFFECT: higher static crosswise stability, reduced blade angle of propeller blades.
