    摘要:

    随着全球贸易的发展,浮升一体化混合飞艇是全球远距离、大载重运输平台的重要选择,逐渐成为国内外研究热点。为了提高浮升一体化飞艇的运输效率,对其布局及参数敏感性进行了研究。针对艇身布局和尾翼布局进行了探讨,提出了几种高升阻比布局的艇身和尾翼型式。同时,进行了设计参数对气动特性影响的敏感性分析,结果表明,艇身宽度对飞艇升力系数、阻力系数和最大升阻比的影响最为明显,其相对敏感性系数为尾翼纵向位置和倾斜角的近十倍;尾翼倾斜角对飞艇力矩系数的影响最强,其相对敏感性系数为艇身宽度的两倍多。

    Abstract:

    With the development of global trade, buoyancy-lifting hybrid airship is an important choice for global long-distance and large-load transportation, it has gradually become a research hotspot at home and abroad. In order to improve the transportation efficiency of buoyancy-lifting hybrid air-ship, its layout and parameter sensitivity are studied. Discussions are conducted on the hull layout and tail wing layout, and several types of hull and tail wing layouts with high lift to drag ratios are proposed. At the same time, a sensitivity analysis is conducted on the impact of design parameters on aerodynamic characteristics. The results indicate that, the width of the hull has the most signifi-cant impact on the lift coefficient, drag coefficient, and maximum lift to drag ratio of airships. Its relative sensitivity coefficient is nearly ten times that of the longitudinal position and inclination angle of the tail wing. The inclination angle of the tail wing has the strongest impact on the torque coefficient of the airship , and its relative sensitivity coefficient is more than twice the width of the hull.
