舰载机着舰轨迹上的流场特性对舰载机的安全准确着舰具有重要影响。本文以“尼米兹”级航空母舰为研究对象，建立简化三维数模，并对其舰载机进舰轨迹进行分析。基于Ansys软件，采用结构化网格对整个流场分析区域进行网格划分，并进行流场仿真。分析不同风速和风向角下舰载机进舰轨迹上的流场特性，分析表明：舰载机进舰轨迹上的垂向风影响随着甲板风和风向角的增加而增大；侧向风随着甲板风的增加而震荡加剧，且风向角越大，侧向风峰值也随之增加。

The flow field characteristics of the landing trajectory of carrier-based aircraft have great impact on the accurate and secure landing on the aircraft carrier. A simplified mathematical model is established for the Nimitz-class carriers considering its six-degree-of-freedom movement. Based on the model above, the landing trajectory of carrier-based aircraft is discussed. The entire flow field that needs analysis is meshed through the structured grid in Ansys with simulation analysis. The flow field characteristics of the landing trajectory of carrier-based aircraft are analyzed with different wind speed and direction, which indicate that the increase of the deck wind and its angle causes the increase of influence of the vertical wind;the stronger the deck wind and its angle is, the stronger shock and higher peak of the lateral wind is.
