Simulation of the Longitudinal Carrier Landing in Different Sea-states for Carrier-based Aircraft

The motion of aircraft carrier has much influence on the safety of the carrier-based aircraft landing process. The model of the carrier motion was established using harmonic equations. The pitch and heave of the carrier were calculated, as well as the movement of the desired touch-down point. The longitudinal landing motion model of aircraft was established with the small-disturbance equations. The automatic carrier landing of the F-18 aircraft at different sea-states was simulated. Considering the randomicity of the carrier motion, the random phase was introduced into the carrier motion equations. The model was simulated 200 times separately at sea-state 3, 4 and 5. The results show that the higher sea-states induces the severer carrier motion, thus the horizontal deviation of touch-down points gets larger and the success rate becomes lower.
