谈到飞艇,人们首先想到的是生活中极为常见的气球。气球是一种无推进装置的轻于空气的航空器,而飞艇是有推进装置的轻于空气的航空器。早在1852年,法国人H·吉法尔就制造了一架装有蒸汽机的飞艇。第一次世界大战期间飞艇主要用于军事,后来广泛用于航空运输。飞艇技术于20世纪30年代已达到鼎盛时期,然而到了二战期间,速度快得多的飞机广泛使用,使飞艇的速度慢、易受攻击、生存力低的缺陷越发突显。自那时起,天空中到处飞翔着大
When it comes to airships, the first thing people think of is the very common balloon in life. A balloon is a light-weight aircraft without a propulsion unit, whereas airships are lighter-than-air aircraft with propulsion. As early as 1852, the Frenchman H. Guifal created an airship with a steam engine. During the First World War, airships were used primarily in the military and were later widely used in air transport. The airship technology reached its heyday in the 1930s. However, by the time of World War II, much faster aircraft were used, making the airships slow, vulnerable and underpowered. Since then, the sky has been flying large
