Aerodynamic and overall parameters analysis of buoyancy-lifting hybrid airship

  • 摘要: 为了兼顾飞艇的气动性能和浮升特性,充分发挥二者的优势,并增强可控性,提出了一种基于NACA高升力翼型的组合嚢体式混合飞艇气动布局.采用计算流体力学(CFD)方法建立混合飞艇FLUENT计算模型,数值模拟了它在不同速度和迎角下的升阻特性、纵向静稳定性及浮升特性,并进行了总体性能评估,最后将其与常规飞艇进行了对比.结果表明:该组合嚢体飞艇布局具有较好的气动性能和效率,相同条件下提供的动升力为常规飞艇的3倍;当飞行速度大于26 m/s时,混合飞艇总升力效率开始大于常规飞艇,能够提供更好的浮升特性.此外,相同设计载荷下混合飞艇的外形尺寸更小,有利于增加有效载荷,可为低空大型混合飞艇的研发提供参考.
