FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering, particularly, to wing-unfolding system. Aircraft wing unfolding system comprises pneumatic cylinder (1) with piston (2), carriage (4) rigidly fixed on piston (2), right (7) and left (8) wing pins installed in brackets with possibility of their axial and longitudinal movement. In upper parts of wing pins there are levers (9) connected by links (10) with carriage (4). Outer wing panels are installed on lower ends of wing pins. In the lower part of the wing pins there are mechanisms for raising the outer wing panels along the axis of rotation of the pins, which are cylindrical screw gears consisting of lower cylindrical parts (13) and upper cylindrical parts (14). Each of lower (13) cylindrical parts is rigidly connected to its bracket of the wing pin, and each of upper (14) cylindrical parts is rigidly connected to its wing pin.
EFFECT: simplified design, reduced weight and higher reliability.
