    Now, these two moments must be in equilibrium with an aerodynamic moment produced by a cyclic pitch variation in the tip path plane, and the rotor achieves this by appropriate tilts a1 and b1 relative to the shaft. This cyclic pitch variation, by the arguments of section . The central idea is based on modifying the normal passive suspension system into a computer controller hydraulic actuated active suspension system simply by adding a new component such as a hydraulic cylinder on a normal passive system. The new suspension system is economical to be wildly used in consumer's cars with low prices.

    The design of the pitch-change horn, coupled with placement of the servo and tilt of the swashplate, provides the total offset.
