“同翔”号无人机的升阻特性与纵向静稳定性

Lift/draft Properties and Longitudinal-stability of Unmanned Plane “Tongxiang”

介绍了"同翔"号无人机设计的基本情况;采用涡格法气动软件AVL,对"同翔"号飞机的气动特性进行了理论分析,并根据计算结果讨论了该飞机的升阻特性和纵向静稳定性等。研究表明,"同翔"号无人机的气动性能良好,升阻特性及纵向静稳定性满足既定要求。

with one unmanned civil plane as investigated object, the lift, drag and pitching-moment coefficients are calculated by AVL, an eddy-lattice-method based aero-dynamics software. In order to ensure the rationality of the unmanned plane on aero-dynamics properties, the calculated results are further discussed on theory. It is shown by flight-test that the present unmanned Diane is successful on design, and is excellent in lift/draft properties and Iongitudinal-stabilitv as well.
