一种飞翼式布局飞机波浪形压力舱的结构探讨

Structural Discussion of Pressure Cabin Characterized with Wave-section Surfaces of Fling-wing Aircraft

提出了一种"波浪形"压力舱的飞翼式布局飞机外形,建立了波浪形壁板的力学模型并对壁板厚度和曲率进行了优化,基于波浪形压力舱的受力特性对其进行了结构布置,借助Nastran有限元方法,对波浪形压力舱和多泡压力舱进行了初步计算和分析,结果表明波浪形压力舱在结构上是可行的,但重量稍重。

A lfying wing aircraft with a wave-section pressure cabin is proposed, and the mechanical model of the wave-section panel of the cabin is established. The optimization of the thickness and curvature of the panel is then carried out. A structural layout of the pressure cabin is proposed based on the optimization results. The preliminary analysis with respect to the structural layout is done by comparing with the multi-bubble conifguration by employing the Nastran solver. The results suggest that the structural layout for the wave-section pressure cabin is sensible, however it probably brings more weight.
