超高空动升力翼飞艇的气动研究

对在超高空环境下的动升力翼 "X"形尾翼布局飞艇和常规飞艇进行了数值模拟,比较了两种外形在相同任务载荷下体积、质量以及气动力的大小,并分析了动升力翼绕流对尾翼的影响.研究发现,动升力翼 "X"形尾翼布局可以显著地减小飞艇的体积和质量,增加抗风能力并避免了动升力翼绕流对尾翼的直接干扰以及大的干扰阻力的形成.

Aerodynamic Analysis on a Superaltitude Winged-airship

This paper proceeded numerical simulations on a winged-airship and a conventional one at superaltitude.The two airship volumes,mass and aerodynamic forces were compared with a same assignment load.The flow was disturbed by the lifting wings and the downstream influence on the tails was studied.The research discovered that,the winged and X-tails layout could obviously reduce the airship volume and mass,increase wind resistant ability,and avoid the direct disturbance to the tails by the lifting wings,as well ...
