| 摘 要： | 以数值模拟为手段,对临近空间飞行器典型的气动布局进行了大量的计算和评估分析,对不同的气动外形进行了多方面的对比研究.结果表明,在不同的速度范围内,各气动布局外形具有不同的气动和浮升特性,不同飞行速度的飞行器在选择气动布局形式方面存在很大差别,为浮升一体飞行器的选型设计提供了一种指导.

| Abstract: | Through the numerical method,the typical aerodynamic configurations for a vehicle in the near-space are investigated.Different aerodynamic configurations are studied contrastively.Based on the calculation work,new buoyancy-lifting configurations are presented for future study.The study results indicate that different configurations take on different aerodynamic and buoyancy-lifting characteristics.There is great difference in selecting the aerodynamic configurations for vehicles in the different cruise spee... |
