For amphibians aircraft, ground and water handling characteristics should meet the requirements of airworthiness regulations, and an accurate computation analysis method should be established to carry out the evaluation during the optimization design process of the aircraft scheme, so as to ensure the airworthiness compliance of the aircraft scheme and reduce the risk of design change. Based on the sliding boats hydrodynamic analyzing methods, landing gear system multi-body dynamic modeling technology and Matlab/Simulink simulation environment, the mathematical flight simulation models of flying boat in water and on the ground are built respectively. The time history of various motion state variables, undercarriage parameters, and hydrodynamic forces of the aircraft are obtained after the simulation. Finally, a contrastive analysis of the taking-off process between the simulation results and experimental data is made. The results show that the ground and water flight simulation method is consistent with test data of the amphibious aircraft, can achieve the accuracy requirement of the aircraft design.
