Due to the strong nonlinear change of aerodynamics with flight altitude and wind direction always being parallel in wind tunnel, the important aerodynamic derivative to climb angle is hardly to be tested. In this paper, a theoretical method of acquiring partial dynamic derivative of the wing in ground effect vehicle is derived by using the forced vibration of WIG vehicle above a certain flying height. At the same time, the aerodynamic characteristics of WIGS of XTW series are analyzed by means of fluent code using the theoretical method developed. It is shown that the numerical simulation method is reasonable compared with the experimental value, and the theoretical method of acquiring partial dynamic derivative of the wing in ground effect vehicle is feasible.enhttp://rightsstatements.org/vocab/InC/1.0/Aerodynamic derivativesGround effectWingComputational Fluid Dynamics (CFD)TechnikIngenieurwissenschaftenConference Paper10.15480/882.333910.15480/882.3339Fluiddynamik und Schiffstheorie M-8Conference Paper
