| 摘 要： | 叙述了雷诺数对战术导弹零升阻力的影响，并给出了适合战术导弹的零升阻力系数雷诺数效应修正方法，即变雷诺数试验外推修正方法及工程计算方法。修正结果表明，修正方法是可行的，变雷诺数试验外推法得到的修正量比工程计算得到的修正量更为合理，对于外形简单的战术导弹工程计算仍有较好的精确度。

| Abstract: | This paper presents that Reynolds number have an effect on zero lift drag of tactical missiles.The correction methods are given for Reynolds number effect on zero lift drag.They involve extrapolation method by changing Reynolds number test and engineering calculation.On the basis of the correction results,it appears that this method is available.The results obtained from extrapolation method are more reasonable than those from calculation.For the tactical missiles involving simple configuration,the latter is accurate enough. |
