Abstract: In this paper, the front fuselage structure of a carrier-based aircraft and some components of the nose landing gears are studied. The dynamic responses of the structure under the impact force during the ejection process are analyzed. A comparison is made between the ground ejection test and rigid-flexible coupling simulation. The test results are found to be consistent with the simulation results, verifying the feasibility and reliability of the ground ejection impact test and the method of rigid-flexible coupling simulation. Based on the test and simulation results, the maximum overload transferring paths are obtained, as well as the strain and stress distribution of the aircraft fuselage structure during the ejection process. The results of the ground ejection test and simulation can provide reference to structure design, strength check and the whole aircraft ejection test for the carrier-based aircraft.

Key words: carrier-based aircraft, ground ejection, impact loading, dynamic response, rigid flexible coupling simulation
