A New Carrier Deck Pitch Motion Compensation Strategy

A new carrier deck pitch motion compensation strategy was designed to compensate the adverse effects that pitch motion of carrier acts on aircraft landing. The desired approach velocity of aircraft was calculated by velocity controller when aircraft was approaching, and the aircraft approached with desired approach velocity to guarantee the purpose that carrier pitch reached to 0° when aircraft landing, which means the carrier pitch motion compensation is accomplished. The excess adjust of velocity was avoided by restricting the range of desired approach velocity, which reduce the influence that compensation strategy acted on the flight path adjustment ability of aircraft. The new compensator with proposed strategy was build and added into automatic carrier landing system, and a full approach simulation results verified the effectiveness of the new design.
