A rotorcraft includes a frame and an engine coupled to the frame. The rotorcraft also includes a rotor hub coupled to the engine and a plurality of rotor blades coupled to the rotor hub. Each rotor blade is configured to be adjusted to a negative pitch angle such that each rotor blade is oriented at a negative angle of attack. The rotation of the plurality of rotor blades at the negative pitch angle generates an updraft that, during a vertical take-off operation, applies an upward force to the rotorcraft to supplement lift generated by the plurality of rotor blades.
