Abstract:

The vertical motion of an ideal touchdown point is a main factor affecting the accuracy and safety of carrier landing. Therefore a carrier aircraft’s ability to synchronously track the vertical motion of the ideal touchdown point is of critical importance. For this, a method of predicting and compensating for the vertical position and speed of the ideal touchdown point is proposed in this paper. The vertical position and speed signals of the ideal touchdown point are first processed by the predictors and compensators and then connected to the longitudinal automatic carrier landing system and vertical speed channel of the flight control system as inputs, which helps the carrier aircraft track the vertical motion of the ideal touchdown point and decreases the influences of deck motion on carrier landing. The designed compensators and predictors are examined and compared with other methods through simulations in different sea states. Simulation results show that the deck motion predictors and compensators designed in this paper can effectively compensate for the landing error caused by deck motion and significantly improve the safety and accuracy of carrier landing.

Key words: carrier landing, ideal touchdown point, motion prediction, motion compensation, automatic carrier landing system
