Abstract: A six-degree-of-freedom dynamics model of landing and arresting of a carrier-based aircraft is established taking asymmetric situation into consideration.The aircraft dynamic response during arresting is calculated.The effect of carrier movement on the arresting performance is analyzed, and the kinetic cause of this phenomenon is also discussed in detail.From the landing and arresting calculation, three important conclusion are obtained:the pitch and heave, the roll and yaw movement of carrier are the primary source of the longitudinal and lateral landing error respectively;The effects of carrier movements on arrest-stop distance and acceleration in the heading direction differ in the degree, while they are pitch, roll, heave and yaw movement in descending order;Under the asymmetric arresting force, the lateral error is corrected.
