翼片结构参数对单翼末敏弹气动特性的影响

摘要

为了研究单翼末敏弹气动布局对其气动特性的影响规律,基于Fluent软件,详细研究了翼片长度、翼片宽度、翼端重物质量和翼片转角等参数对单翼末敏弹阻力系数、导转力矩系数和俯仰力矩系数的影响规律.结果表明,气动参数随翼片长度和宽度增大呈现线性增大趋势;翼端重物质量对气动参数影响微弱;翼片转角对气动参数影响较大,气动参数呈现抛物线形变化.%In order to research the influence law of the single-blade terminal-sensitive projectile on its aerodynamic characteristics,based on commercial software Ansys Fluent,the influence law of wing's length,width,tip mass and rotating angle on drag coeffiecient,rotating moment coeffiecient and pitching moment coeffiecient was studied in detail.The results showed that the aerodynamic parameters increased linearly with the increase of wing length and width.Wing's tip mass slightly affected on aerodynamic parameters,while the wing's rotating angle strongly affected on aerodynamic parameters which presented parabolic variation.
