Abstract: In this article,a study is made of the collision dynamics of the arresting hook bounce after initial touchdown when the aircraft is arrested, and a collision bounce model is built. The impact of flight path angle and deck angle on bounce angle velocity and the impulse of collision by aircraft and deck are explored. The dynamic performances of bounce angle velocity affected by the pitch movement of the aircraft carrier and deck barrier are analyzed. The results show that when the flight path angle is about 4°, the bounce angle velocity and impulse of collision increase linearly with the flight path angle; the bounce angle velocity is inversely proportional with the cosine of the deck angle; the impulse of collision by aircraft and deck is inversely proportional with the squared cosine of the deck angle; the velocity of collision in the impact direction is increased by the pitch of the aircraft carrier and deck barrier, and the impulse of collision by fuselage changes direction when the deck barrier angle reaches a certain degree. The results of this model provide an important foundation for fuselage and arresting hook device design.
