单项技术指标对临近空间浮空器总体尺度的影响

Size of High Altitude Long Endurance Airship Affected by Various Technology Guidelines

为了控制浮空器的尺度、降低其技术难度和成本,需要明确其瓶颈性技术领域及参数指标。在一定假设下,给出了一套给定参数估算常规飞艇形式浮空器总体几何尺度的计算流程。基于这一流程,以一组普通产品技术指标为基础,分别提升其中每一项后估算得到不同技术指标配置方案下浮空器的总体尺度。通过分析这些计算结果,得到了单项技术指标对飞艇形式临近空间浮空器总体尺度的影响规律。

In order to cut the cost, high altitude-long endurance airship size and technology difficulties should be reduced. So the bottleneck technology fields and their parameters must be identified. A computation process which used to get high altitudeqong endurance airship size with a set of initial parameters and assumptions was brought forward, whose shape like the common airships, such as HAA and ＂Zeppelin＂ airship. The sizes of various high altitude-long endurance airship schemes were computed using the computation process. All technology guidelines of basic airship schemes were general. And other schemes had a technology guideline upgraded. They were compared with the basic high altitude-long endurance airship schemes. Then the affection rules for each technology guideline were presented by analyzing the computation results. The reason was analyzed, which caused the huge size of high altitude-long endurance airship. Finally, a creative way to reduce the size of high altitude-long endurance airship was brought forward.
