Carrier-based aircraft is the main weapon in aircraft carrier. In order to meet the requirements of taking off, landing and parking, the design of the carrier aircraft must be centered around "characteristic structures" such as the landing gear system, arresting hook system, and wing folding system. The impact energy of the advanced carrier aircraft is more than 6 times that that of the land-based aircraft, and the horizontal load brought by interception is 15 times higher than that of the land-based aircraft. Therefore, high load on the "characteristic structures" presents higher requirements on the strength design. This paper details the design work around the "characteristic structures" and "characteristic loads" of the carrier aircraft, including calculation of "characteristic loads", i.e. landing gear load, barrage load and folding load; strength design and test verification of "characteristic structures" including dynamic simulation of the landing gear system, barrage system and wing folding system, static/fatigue strength analysis, flutter analysis of folding wing surface, and post-test analysis of the impact of drag force on the body structure strength; analysis of dynamic response of landing on ship and influence of the combined action of landing load and barrage load on the strength of the aircraft structure; discussion of the test verification methods reflecting the strength characteristics of the "characteristic structures" of the carrier aircraft. The above research results have been successfully applied to the design of advanced carrier aircraft.
