摘　　要：针对气象探测火箭载荷轻、速度高的特点,对气象探测火箭进行气动力3维数值模拟。以某型小口径大长径比气象探测火箭弹为基础,进行全弹建模与计算,分析其在跨音速情况下的气动力特性,验证了该种大展弦比刀形尾翼在小口径大长径比跨音速气象探测火箭弹上的可行性。结果表明,该分析可为小口径大长径比火箭弹的尾翼设计提供参考。According to the characteristics of light load and high speed of the meteorological sounding rocket,the aerodynamic 3D numerical simulation of the meteorological sounding rocket was carried out.Based on a certain type of small bore large length-diameter ratio weather detection rocket,the modeling and calculation of the whole rocket were carried out,and the aerodynamic characteristics of the rocket at transonic speed were analyzed.It was verified that the high aspect ratio knife-shaped tail was feasible in the small bore of large length-diameter ratio transonic weather detection rocket.The results show that the analysis can provide a reference for the fin design of small bore rocket with large aspect ratio.
