| 摘 要： | 文章提出了一种翼艇式飞行器方案,较好地解决了以低速在临近空间飞行的两个关键问题:①如何利用临近空间稀薄空气产生升力克服飞行器重量;②如何有效利用有限太阳能产生飞行器长时间飞行的动力。该飞行器采用了升浮一体飞行原理和昼夜节能运行模式,将夜间储能锂电池的重量大幅度减小,比临近空间飞艇的体积缩小一半左右,飞行速度有较大提高,对于有速度要求的任务载荷(如SAR)来说更适合。文中还建立了翼艇式飞行器的总体参数优化模型,并采用NSGAII得到了多种满足设计要求翼艇式方案,选择了非劣前沿解集中柺折处方案。将该优化模型和方法得到临近空间飞艇方案总体参数与洛马公司公布的高空飞艇总体参数进行了比较,结果较为接近,表明该优化模型和方法的准确性,对低速临近空间飞行器设计有一定的参考价值。

| Abstract: | Aim.The introduction of the full paper discusses existing problems and then proposes our exploration,which is explained in sections 1,2 and 3.To solve two critical problems for the flight of a winged airship in near space at low speed,section 1 uses rarefied air to produce the lift of a winged airship and balance its weight and the limited solar energy to produce the power needed by the winged airship for long-time flight.Section 2 designs the configuration of the winged airship;its core consists of:(1) the... |
