Abstract
A flight control system for a rotorcraft to prevent the adverse effects of the vortex ring state is disclosed. In the flight control system of the present invention, selected control inputs are sent the rotorcraft prior to the onset of the vortex ring state. In the preferred embodiment, the control inputs are transient, do not require input from the pilot, and do not affect the flight path of the rotorcraft.
