This invention discloses a biomimetic dragonfly flapping-wing aircraft with adjustable sweep amplitude driven by an air source, belonging to the field of aircraft technology. It includes: a base plate support, a transmission mechanism, a sweeping flapping mechanism, a pair of front flapping wings, and a pair of rear flapping wings. The transmission mechanism includes a front air source driven transmission mechanism and a rear air source driven transmission mechanism with identical structures located on the front and rear sides of the base plate support, enabling differential sweeping movements of the two pairs of flapping wings. Each flapping wing root is equipped with an adjustable sweeping flapping mechanism and a micro-gear. The front air source driven transmission mechanism drives the sweeping support to rotate circumferentially via an air source rotating blade engine, which in turn drives the flapping wings to sweep through a sweeping swing frame. The amplitude and speed of each flapping wing's sweeping movement can be controlled independently. During flight, the sweep amplitude or speed of the front and rear flapping wings on the same side can be controlled to be greater than that of the front and rear flapping wings on the other side to achieve turning movements and tailless flight control.
