In the design of amphibious aircraft

dynamic response characteristics of the elastic aircraft should be considered. According to the working modes and using characteristics

dynamic response characteristics of the large amphibious aircraft when taking off and landing on water

encountering symmetrical / asymmetric gust and landing are analyzed by numerical calculation method

and dynamic loads response of the structures in various using environments are solved. Results show that limited dynamic loads of the local positions are notable larger than the static loads due to dynamic response for the large amphibious aircraft

so dynamic loads must be used to additional design and check for the structural strength. Analysis results provide important reference for structural design of the large amphibious aircraft.
