临近空间浮空器总体参数的优化设计研究

临近空间飞行器是目前新概念飞行器发展的一个热点,本文研究了临近空间浮空器设计过程中对其在总体参数进行几何尺度控制的相关问题。在一定的基本假设和约束条件下,给出了一套参数估算常规飞艇形式临近空间浮空器的总体几何尺度的计算流程。利用这一流程进行计算,得到了几项单项技术指标对于该种类型浮空器总体尺度的影响规律,讨论了控制缩减总体尺度可以优先发展的技术领域。最后分析了载重量对于浮空器尺度的影响情况。

Optimization on Sizing of High-Altitude/Long-Endurance Airship

High-altitude/long-endurance airship is one of new concept aircrafts.This paper addresses some issues which are related to reduce the size of high-altitude/long-endurance airship.A computation process is brought forward which is used to get the airship size with a set of tentations and restrictions.The influence rules of the high-altitude/long-endurance airship size with some technology guidelines are presented by analyzing the computation results.Then the technique fields are discussed which are helpful to reduce the airship size.Finally,the rules of airship size affected by payload are brought forward.
