【摘要】 <正> 飞艇艇体需充以密度比空气小的浮升气体。通常采用氢气,氦气和热空气、水蒸气也是一种可应用的浮升气体。我国地势可大致划分为3个地势台级,各地势台级下使用各种轻于空气的气体浮力计算结果如图1所示。 1.氦气 是惰性气体,不会燃烧、爆炸,是仅次于更多还原

【Abstract】 First of all, the foreground of developing airship in ourcountry is illustrated. Then, the main difficulty--lack of helium, for theairship development is discussed. Consequently, a new scheme of structural design about hydrogen-airship is given, taking advantage of over helium-airship and avoiding accurence of burn-exploding.更多还原
