摘　　要：针对飞机后体阻力问题,以双发机动飞机后体模型为研究对象,对多种后体流场控制措施进行了分析研究,利用数值模拟和风洞试验的方法进行验证和对比,给出了不同措施下后体阻力随M数的变化规律,可为工程化应用提供参考。Analysis and research have been conducted on the aflerbody model of twin-engine maneuvering aircraft by the methods of numerical simulation and wind tunnel tests. Effects of different control measures on afterbody drag are obtained, as well as the flow field distributions. Based on the research results, afterbody models adapted to different flying Mach numbers are presented, which can be taken as reference for engineering application.
