摘要
舰船在海面上航行会在其尾部产生强烈的大气扰动,其中最主要的就是舰尾流,它的存在对飞机的着舰有着重要的影响。在美军标相关说明的基础上得出了舰船舰尾流模型,并分析了舰尾流对飞机下滑过程的影响,从而建立了含有尾流影响的飞机下滑过程的六自由度运动方程,求解了在这过程中的飞行姿态。仿真结果表明,舰尾流对飞机在下滑过程中的姿态影响较明显。该方程的建立,对控制着舰飞机的飞行,维持平衡的飞行状态有很重要的作用。
On the voyage, strong atmospheric turbulence will be produced at the stern, the primary one of which is the air wake, which is very important for the plane＇s landing. Based on the ship＇s air wake model which was drawn from the correlative instructions of the united states military standard and the analysis of air wake＇s effects on the plane＇s gliding process, we came out with a six-degree-of freedom e- quation and found out its flying attitude during this process. The finding shows us that air wake plays a significant role in the plane＇s landing posture and the establishment of the equation is crucial for the con- trol of the plane and the balance of the flight.
