摘　　要：为进行线性与非线性飞行控制设计及实时仿真的研究,建立了全量非线性倾转旋翼机飞行动力学模型。在基本动力学方程中,考虑了短舱倾转动态的影响;对于动力学方程中的力与力矩,采用分体法对各个气动部件模型进行了分解分析。最后,针对倾转旋翼机模型特点,采用两种不同算法进行了配平计算,配平结果与GTRS(Generic Tilt-Rotor System)结果相符,证明了模型的准确性。For linear/nonlinear flight control design and real-time simulation, this paper presents the full nonlinear flight dynamic model of tihrotor aircraft. Primary dynamic equations of the model are developed with the consideration of nacelles tilting dynamics. The force and the moment in primary equations are decomposed and calculated by multi-body aerodynamic models. Because the number of unknown parame- ters is greater than that of equations, two different algorithms are applied to trim the mathematical model. The results by these trimming methods are in conformity with each other. The result of trimming is with the same as GTRS so that the model is valid.
