Abstract:

In order to research the dynamic performance of the arresting hook after touchdown and impacting with the deck when the aircraft is arrested, a full-aircraft assembly model of a certain type of aircraft is developed to conduct dynamics simulation of the landing of the aircraft carrier. The model is updated with the data of arresting hook bounce test, and a more accurate model is obtained. The simulation results are compared with the test results, and the accuracy of the dynamics model is verified. The impact of the deck coating, pitch angle, engaging velocity, sinking velocity and parameters of the arresting hook damper on the dynamics performance of arresting hook bounce is studied. The results show that the engaging velocity has little effect on bounce height and impact force. The bounce height and impact force get larger with the increase of the sinking velocity and pitch angle. The parameters of hook damper almost have no effect on the impact force, but obvious effect on the bounce height.

Key words: carrier aircraft, arresting hook, impact, dynamics, damper
