为了分析柔性弹翼的气动特性,采用气动仿真软件分析了不同弹翼翼型的升阻比特性,获得了弹翼表面鼓包和弯曲变形对巡飞弹飞行气动特性的影响规律,采用模型飞行技术对柔性弹翼进行了试飞测试验证,结果表明柔性弹翼表面鼓包使得其阻力系数约增加5%,一定的挠度使得其升力系数相比于无弯曲变形时大幅提高。通过创新性地给弹翼增加光滑蒙皮进行整形,有助于负载能力和飞行质量的提升。
In order to analyze the aerodynamic characteristics of flexible wing, aerodynamic simulation software was used to analyze the characteristics of lift-drag ratio of different wing-wing airfoils, and the effect of bulge and bending deformation on the aerodynamic characteristics of the missile was obtained. The flight test of the wing was carried out. The results show that the bulge of the flexible wing surface increases its resistance coefficient by about 5%, and the certain deflection makes the lift coefficient significantly increase compared with that without bending deformation. By innovatively adding a smooth skin to the wing to shape, it contributes to load capacity and flight quality.
