巡飞器巡飞段动力学建模与仿真研究

动力学建模对于巡飞器的设计和仿真是至关重要的。与传统的飞行器相比,由于其飞行的速度比较慢和高度低、受外界的影响大,巡飞器的飞行动力学特性相当复杂。为了研究巡飞器的一些本质的动力学特性,选择巡飞器巡飞段分析,建立了巡飞段的巡飞段动力学模型。利用DATCOM与气动仿真对比得出数据,建立了空气动力学数据库。最后,在MATLAB/SIMULNK动力学仿真,仿真结果验证了该原理的可行性,为下一步的研究工作奠定了基础。

Flight Dynamics Modeling and Simulation of Loitering Monition in Loitering phase

Dynamic modeling was very important for design and simulation of Loitering Monition. Compared with traditional aircrafts the flight dynamics feature of loitering monitions was unique and complex because its flight speed was slower with lower altitude. The purpose of this research was to bulid the model of loitering monition in the loitering phase and to provide an insight into the inherent dynamics. Based on data acquired from aerodynamic simulation, the aerodynamic database was built. Finally, nonlinear si...
