摘要

为研究侧向喷流对导弹大攻角气动特性的影响,采用CFD计算方法对在侧向喷流干扰下的导弹流场进行了模拟。通过研究喷口附近流场结构与物面极限流线分布,分析力和力矩放大因子随攻角变化曲线,并采用“单位长度法向力系数增量”和“单位长度俯仰力矩系数增量”对放大因子曲线变化特点进行了研究,结果表明喷流位于迎风侧时干扰流场结构复杂,喷流干扰对导弹压力分布形成四个主要影响区。

Abstract

The interaction between a lateral jet and external flow over a missile was simulated numerically through computational fluid dynamics (CFD) for investigating the aerodynamics of missile at high angles of attack (AOA). Through studying the characteristics of the flow structure and the limited streamlines near the lateral jet, analyzing the force/moment amplification factor diversification curves, and using double new study parameters for investigating the features of the force/moment amplification factor diversification curves, the results indicate that the effect of the jet interaction at windward side is complicated than that at leeward side, and lateral jet interaction on tactical missile forms four influence zones

Key words： missile; lateral jet; high angle of attack; computational fluid dynamics
