摘　　要：介绍了在0 .3m ×0 .3m 高速风洞中进行的某研究型大口径机枪双头弹空气动力特性试验研究。文中给出了试验模型、试验方法、数据处理方法以及试验结果,最后对该结果进行了详细分析。试验结果表明该双头弹模型符合小攻角下弹丸空气动力特性的一般规律。The experimental study of aerodynamic characteristics of large caliber duplex ammunition in HG 4 0.3m×0.3m high speed wind tunnel is introduced in this paper. The diagrams of models are given, the test methods and data processing methods are presented briefly, and the test results are obtained. Finally the analysis of the results is presented in detail. The test results have proved that the models of duplex ammunition accord with the laws of aerodynamic characteristics of bullet under small angle of yaw, and the shape of the duplex ammunition still needs to improve.
