飞机六自由度模型及仿真研究

以国产某型号飞机为背景提高出六自由度飞机对象建模的一般方法和原则。此建模方法直接根据牛顿第二定律推导出全量非线性方程，没有对刚体运动模型和气动数据做线化处理，考虑了飞机纵横向之间的耦合作用和决定飞机性能的绝大多数因素，因此该模型更精确、更全面地反映了飞机的实际运行特性，并具有具较强的通用性。

Modeling and Simulation Research of Six-Degree-of-Freedom Fighter

With background of a certain model of homemade fighter, this paper puts forward a general method and principle of establishing simulation model of six degree of freedom fighter. By this modeling method the whole non linear equation is derived directly from the Second Newton Law without linearization of movement model of rigid body and aerodynamic data. It studies coupling influence between longitudinal and lateral, and takes main factor of fighter performance into account, so the model represents flight characteristics of fighter more accurately and effectively, and it is more universal. The simulation software MATRIXX is used as developing platform which improves simulation means greatly, and makes researcher break away from the old work mode.
