The invention provides a light flexible wing with a variable-camber
trailing edge. The light flexible wing comprises a
leading edge ribbed plate (1), a front spar (2), a middle ribbed plate (3), a rear spar (4), the flexible
trailing edge (5), a motor support base (6), a
linear motor (7), a motor and flexible
trailing edge connecting rod (8), a flexible trailing edge and guide rail connecting plate (9), a slider (10), a guide rail (11), a slider and flexible trailing end connecting plate (12), a pull ring (13) and a
skin. The
linear motor (7) is electrified, the pull ring (13) on the flexibletrailing edge (5) is pulled or pushed, under the action of the push-
pull force, and the pull ring (13) does
linear motion and drags the upper and lower sides of the flexible trailing edge (5) to be bent and deformed. Aiming at the limitations of a traditional wing flap and an existing adaptive wing flap, the whole structure can have high stability when a
large deformation is generated, and the light flexible wing has the advantages that the
mass is low, and the light flexible wing does not occupy extra wing space.
