摘　　要：为研究濒海战斗舰(littoral combat ship,LCS)的飞行甲板空气尾流场特性,本文采用仿真软件对“独立级”濒海战斗舰(Independence-class littoral combat ship,LCS-2)进行分析计算,将LCS-2的流场仿真数据与孤立护卫舰简化模型(SFS2)的仿真分析和风洞试验数据进行对比分析,得到LCS-2尾流场对其舰船甲板气动环境的影响。由对比结果可知:相较于SFS2,LCS-2在舰船起降甲板的大范围内均具备更适合舰载机起降的气动环境,起降甲板面积占船体总面积的比率以及机库门的倾斜程度同样对舰船尾流场存在明显的影响,研究结果能够对LCS的相关研究提供数据支撑。In order to study the air wake field on the flight deck of the littoral combat ship(LCS),some characteristics of the“independence class”littoral combat ship(LCS-2)is analyzed and calculated by FLUENT The flow field simulation data of LCS-2 are compared with the simulation analysis and wind tunnel test data of an isolated simplified frigate shape(SFS2)model,and the influence of LCS-2 wake flow field on the aerodynamic environment of its ship deck is obtained.Compared with SFS2,LCS-2 has a more suitable aerodynamic environment for a carrier-based aircraft to take off and land in a wide range of the ship′s takeoff and landing deck.The ratio of the takeoff and landing deck area to the total hull area and inclination of the hangar door also have an obvious influence on the ship wake field.The research results can provide data support for relevant research of the littoral combat ship.
