多片弹翼反坦克导弹气动特性实验研究

An Experiment Investigation of the Aerodynamic Characteristic for a Multi-wing Light Antitank Missile

以美国的'新标枪'轻型反坦克导弹外形为基础,采用部件组合法设计一组风洞实验模型,进行六分量测力实验,实验马赫数范围为0.3～0.5,攻角范围为-1°～15°.实验结果表明:弹翼片数从4片增加至8片可使模型在所实验的马赫数范围内静稳定,法向力、法向过载可提高40%以上,而零升阻力增加量不到5%.对于正常式布局亚声速飞行的轻型反坦克导弹,8片弹翼可能是最佳的选择.

Based on the aerodynamic configuration of New Javelin light antitank missile, a series of wind tunnel experimental model was designed with the component build-up method. Six-component force experiments were conducted for Mach numbers ranging 0.3 - 0.5 and angles of attack -1° - 15°. The experimental results show that, while the wing number increases from four to eight, the experimental configurations are static stabilization and the normal force and normal overload increase more than 40 %, but the increase of zero-lift drag is under 5 %. The experimental results also indicate that eight wing configuration maybe is the best configuration.
