CONVERTIBLE AIRCRAFT AND CORRESPONDING CONTROL METHOD Russian patent published in 2022 - IPC B64C27/28 B64C37/00 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to structures of rotary-wing aircrafts. Convertible aircraft (1) contains fuselage (2), a pair of wings (3, 3’), a pair of nacelles (4) fixed relatively to wings (3, 3’), and a pair of propellers (5) made with the possibility of rotation around axes (B) and with the possibility of inclination around the axis (C) between the first position in an airplane configuration and the second position in a helicopter configuration. Wing (3, 3’) contains wing caisson (20) and first element (22) made with the possibility of movement, when convertible aircraft (1) is in the airplane configuration, between the first neutral position, the second lifted working position, and the third lowered working position. Wing (3, 3’) contains second element (21, 21’) made with the possibility of movement between the first neutral position, when convertible aircraft (1) is in the airplane configuration, in which it forms extension of wing caisson (20), and the second position, when convertible aircraft (1) is in the helicopter configuration, in which it forms hole (50) with wing caisson (20), through which flow bevel created by propeller (5) passes.

EFFECT: minimum impact of movable control elements on flow bevel created in operation of propellers of a convertible aircraft in a “helicopter” configuration.
