Size of high altitude long endurance airship affected by various technology guidelines

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 altitude-long 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 affeclion 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.
