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...
