文中对两种非常规布局的飞艇进行了低速风洞测力实验,给出了实验结果的修正方法,并对升力、阻力和力矩等空气动力特性进行了比较与分析。结果表明:动升力翼布局的飞艇在动升力提供方面优于升浮一体化布局,而后者阻力系数较小,并且是一种纵向静稳定结构,可以有效的减少结构重量,提高飞艇抵抗阵风的能力。因此,采用非常规的气动布局是减小飞艇体积并提高飞艇抵抗阵风能力的有效解决方法之一。

In this paper, a comparative experimental study of two irregular airships in low speed wind tunnel was presented. The correction methods of experimental results were introduced briefly. The aerodynamic characteristics such as lift drag and force moments were compared and analyzed tin detail. The results show that the winged-airship can provide larger lift coefficient, while the lifting body has smaller drag coefficient and has advantage on stability. The structural mass can be reduced and wind resistant ability can be improved by adoption of the irregular airship. Meanwhile, the precious experiment data was provided for airship rarely seen in literature so far, which will be helpful for the future airship design.
