The invention discloses a compound type rotor wing lift device, which belongs to the technical field of aircrafts. The compound type rotor wing lift device comprises a spindle, a rotor wing head, a power device as well as two, three or four identical composite wings which are uniformly distributed around the rotor wing head, wherein each composite wing comprises a foil and two, three or four propellers with identical parameters; the leading edge of each foil is horizontally arranged; the root of each foil is connected with the rotor wing head; the leading edge of each foil is higher than the trailing edge of the foil; all the propellers are arranged below the foils in a linearly horizontal or forward inclined way; the propellers of all the composite wings are driven by one engine, or each propeller is separately equipped with one engine; since the propellers are arranged below the foils, and air current above the foils is led to the rear-lower part when the propellers rotate, air current separation of the upper surfaces of the foils can be put off, and the efficiency and the stability are favorably improved; in addition, attack angles of the foils can be greater, so that that a lifting force generated in unit area of the foils is improved; the device is arranged on an aircraft as the lift device.
