浮空器早在18世纪就已经问世,是飞行器家族中的老前辈。早期的浮空器主要用于侦察、巡逻、轰炸和运输。第一次世界大战期间,世界各国共制造了466艘有动力的浮空器——飞艇。德国使用飞艇袭击不列颠腹地,使2000余名英国人丧生,有效地牵制了协约国约110架作战飞机和近14000人的防空部队,德国“齐伯林”号飞艇因此名扬天下。第二次世界大战期间,仅美国就制造了168艘飞艇。战后,由于飞机技术的迅速发展和广 Aerostats have been around since the 18th century and are the older generation of aircraft families. Early aerostats were used primarily for reconnaissance, patrolling, bombing and transport. During World War I, a total of 466 powered aerostats - the airship - were manufactured in all countries of the world.

As a result, Germany’s Zeppelin was famous all over the world. During the Second World War, only 168 airships were manufactured by the United States. After the war, due to the rapid development of aircraft technology and wide
