飞翼无人机进舰下滑纵向固有模态特性研究
Intrinsic Mode Characteristic Research on the Flying-Wing UAV During Carrier Landing
摘要
Abstract
A grid model of flow field around UAV flying was established for the flying-wing configuration different from the conventional configuration aerodynamic shape, and the UAV aerodynamic parameters could be calculated. The lift coeffi⁃cient, drag coefficient and pitching moment coefficients for angles of attack curve of the UAV by was got the interpolation function. The equation of longitudinal direction small-disturbance motion could be simulated, and the natural mode fea⁃ture of the flying-wing UAV was solved when the UAV was during in carrier landing. The results of the calculation showed that the model could be used in a simulation research of a carrier landing pneumatic suitability of carrier flying-wing UAV under trimmed condition.关键词
