The invention provides a lift force generator. According to the invention, a small-sized device capable of generating air flow, e.g., a radial air intake fan, is arranged in a hollow rotor wing; a stripe-like air inlet is arranged in the leading edge of the rotor wing; the upper surface of the trailing edge of the aerofoil profile of the rotor wing is step-like; and air flow generated by the radial air intake fan blows the upper surface of the trailing edge so as to achieve the purpose of lift enhancement. The lift force generator has the characteristics great lift force and small turning radius of the rotor wing, can be extensively used as a lifting part of a small aircraft and enables the small aircraft to have short take-off and landing capability or vertical lifting and descending capability. The lift force generator is purely power-driven or driven by hybrid power of oil and power, has simple structure, is energy-saving, environment-friendly and safe and is a strong lifting part.
