摘　　要：地效翼船是一种新型高性能船舶。由于地面效应的存在,其气动力随飞高呈强烈非线性变化,同时姿态的变化往往会引起飞高的变化,因此很难通过试验手段获取气动力对爬升角(或迎角)的导数。本文通过构建地效翼船的升沉强迫振动,推导出数值求解地效翼船气动力对爬升角和爬升角速度导数的理论方法,并采用CFD典型算例验证了方法的可行性和合理性,可以作为工程设计和性能估算的重要手段。Wing-in-ground-effect crafts(WIGs) is one type of the latest type of high performance vehicles.As a result of the ground effect, the strong nonlinear aerodynamics are related to flight altitude, and the altitude changes with the change of the attitude angle, it is hard to obtain aerodynamic derivatives corresponding to climb angle by test. In this paper, a numerical method of partial dynamic derivative of the WIGs is derived by using the forced vibration of WIGs at a certain flying height. Aerodynamic analysis of examples by Fluent code proves that the method proposed is rational and feasible, and can be used as a tool in design and performance calculation.
