Flight Control System - Scenario Part 2

When the Controller Computer demands sustained vertical velocity, the Perturbation Computer demands more lift from the blades than that required by the Level Flight Computer. In response, the Blade Computers increase blade camber, and demand more power from the engines as necessary to avoid stall. The vehicle rises at the best rate it can to achieve the velocity demanded.

If the Controller Computer direction demand declines to zero, the hub Level Flight Computer maintains level flight by demanding from the blades sufficient symmetric lift to sustain the vehicle at that altitude in addition to different amounts of lift from each blade as it rotates about the hub for the pitch and roll control necessary to maintain level hover at the position where Controller Computer input ceased.

When the Controller Computer demands a direction that requires both a vertical and horizontal velocity, the hub Perturbation Computer demands from the blades more lift and an attitude change relative to level flight. In response, the blades increase camber in different amounts as they rotate, and demand more power from the engines as necessary to avoid stall. The vehicle moves in the direction and at the velocity demanded.

Given its relative wind information, each blade adjusts its camber for its relative velocity to achieve the lift demands of the hub Level Flight and Perturbation Computers. As the blade sweeps backward, it automatically adjusts to the lower relative velocity with more camber.
