摘要:
为研究非圆截面巡飞弹的气动特性,采用部件组合法设计了风洞实验模型,对单独弹身及巡飞弹进行了六分量测力实验,实验马赫数范围为Ma=0.4~0.6。实验结果表明:弹身对全弹正升力有一定贡献,最大能提供全弹升力的10%;小侧滑角范围内,在没有舵偏的情况下,侧向力、偏航力矩随着侧滑角基本线性变化;巡飞弹具有较好的纵向和横航向稳定性,升阻比高,气动特性在可用迎角内具有良好的线性度。
Abstract:
In order to investigate the aerodynamics of a loitering munition with a non-circular cross section,a suit of wind tunnel experiment models is designed with a modularized method,and 6-component measuring experiments are conducted under the conditions of Ma=0.4~0.6.The experimental results indicate that the non-circular cross section body can provide a finite lift up to 10 percent at a high attack angle(α≥ 6°).The side force and yaw moment of the loitering munition change linearly with the sideslip angle within little sideslip angles.The loitering munition has good longitudinal,yawing and rolling static stability,and high lift-to-drag ratio.Its aerodynamic parameters have excellent linearization within usable angles of attack.
