摘要
本文根据双组尾翼弹的外形特点,选用了代数网格生成方法,通过求解N S方程,对其气动特性进行了数值计算,并对其计算结果进行了分析。由计算结果可知,此种弹的双尾翼可以为其提供一定的转速和升力,提高其静稳定性。并且此种弹已经用于型号设计。
Based on the character of the shape of two sets of empennages bullet, this paper has given its calculation and analysis. It has chosen the algebraic grid generation and calculated the N-S equation to get the aerodynamic coefficients. 32 kinds of states, whose Mach number is 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, and attack angle is 0°, 2°, 4°, 6° have been calculated. According to the results and its graphs, it can be seen that the double empennages, especially its character of oblique, can offer rotation voltage and lift force, and this can increase its stability. In addition, this kind of bullet has been applied to model design.
