TAILSITTER Russian patent published in 2022 - IPC B64C29/02 B64C39/08 B64D27/02 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to structures of vertical take-off and landing aircrafts. Tailsitter aircraft (1’) contains fuselage (2) located vertically in a take-off/landing position and transversely to a vertical position in a cruising position of the aircraft, wing (4), two first engines (15a, 15b) made with the possibility of application of the corresponding first thrusts directed along corresponding first axes (A) to the tailsitter, and two second engines (15c, 15d) rotating around corresponding second axes (A) located above specified first axes (A) of first engines (15a, 15b) in the cruising position. The first and the second engines rest on one wing. The wing contains first section (5) and second section (6), mutually spaced from each other. The second section is located above specified first section (5) in the cruising position. First section (5) contains two half-wings extending from opposite sides of the fuselage. The wing additionally contains third section (30) located below specified first section (5) in the cruising position of the aircraft.

EFFECT: aerodynamic efficiency of a structure is ensured, as well as increase in performance in cruising modes.
