摘要

针对某带卷弧翼的弹箭气动外形,文中利用CFD软件对其卷弧翼滚转特性进行了研究,分析了不同正斜置角及后缘凸面斜切凹槽对卷弧翼滚转特性的影响,结果表明:在卷弧翼上增加正斜置角及后缘凸面斜切凹槽对卷弧翼的滚转特性的影响显著,通过卷弧翼+正斜置角+后缘凸面斜切凹槽的组合设计,能够最终获得满足总体指标要求的滚转特性。

Abstract

A missile with wrap-around fins (WAF) of this paper was computed using software CFD in order to study on effect of different positive cant angle and different convex bevel of trailing edge on rolling characteristics of WAF. The results indicate that positive cant angle and convex bevel of trailing edge of WAF have significant impact on rolling characteristics of WAF. Rolling characteristics meet general requirements by design of WAF with positive cant angle and convex bevel of trailing edge.

Key words： wrap-around fin; numerical simulation; rolling missile; rolling characteristics; wind tunnel experiment
