[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] See also Figures 1 to 4 A scalable wing module includes a module frame 1 and a skin 2, the skin 2 covers the module frame 1, and the skin 2 leaves a lift duct 3 vacant in the middle of the module frame 1. The module frame 1 includes a leading edge keel 11, a side wall panel 12 and a trailing edge panel 13. The two sides of the leading edge keel 11 are respectively connected to a side wall panel 12, and several trailing edge panels 13 are erected between the two side wall panels 12. The leading edge keel 11, the side wall panel 12 and the trailing edge panel 13 form a U-shaped module frame 1 along the lift duct 3; the outer side of the side wall panel 12 is also provided with a quick-release pin buckle 10 connected to other module frames 1.
