The invention discloses a double-propeller combined wing and belongs to the technical field of aircrafts. The double-propeller combined wing comprises a wing panel, a first propeller, a first electric motor, a second propeller and a second electric motor, wherein the wing panel is located above the first propeller and the second propeller; the leading edge of the wing panel is higher than the tailing edge of the wing panel; the downward projection of the wing panel can completely cover the first propeller and the second propeller; the rotary planes of the first propeller and the second propeller are located in the horizontal direction or slightly inclined forwards and downwards; the first electric motor drives the first propeller to rotate, and the second electric motor drives the second propeller to rotate; the double-propeller combined wing moves forwards, coming airflow flows to the rear and lower part of the double-propeller combined wing at an increasing speed under the joint action of the wing panel, the first propeller and the second propeller, and upward lift force and forward push force are generated. During forward movement, the wing bears smaller resistance, the efficiency is higher, the lift drag is higher, and the double-propeller combined wing is suitable for a heavy-load aircraft flying at a low speed.
