The invention discloses a foldable flapping wings and fixed wings coupling-structured aircraft design. Foldable flapping rods are arranged on the leading edges of the flapping wings, wherein the foldable flapping rods comprise inner, middle and outer three-section rod-shaped structures connected through hinges. When the aircraft flies, the flapping rods are unfolded into a rectilinear figure to drive the flapping wings to flap up and down to generate lift force and thrust; when the aircraft lands, the flapping rods are folded into U shape, so as to remarkably decrease the feature size of the aircraft; the fixed wings adopt light shell structures; when the aircraft flies, the shell structures on the two sides are unfolded above the flapping wings and function as a lifting surface for the fixed wings, so that the aerodynamic efficiency of the aircraft is effectively improved; after the flapping wings are folded into U shape, the shell structures on the two sides are folded into a firm and tight half-surrounded shell structure and the folded flapping rods and other components of the aircraft are covered inside the half-surrounded shell structure, so that the occupied space of the aircraft is reduced and meanwhile the integral safety of the aircraft is significantly improved; the aircraft is convenient to store and transport.
