人类很早就有飞行的心愿,最先想制造的飞行器之一是直升机,我国明代发明的玩具竹蜻蜓可以说是现代直升机的雏形。可是直升机第一次试飞成功却是1930年,具有实用价值的升空是1939年,到1945年才真正作为飞行器提供使用,比普通飞机晚一些。直升机跟有固定机翼的飞机不一样,由于它能够垂直起降,能够向任意方向飞行,还能像吊灯一样悬停在空中,起飞和降落又不需要很大的场地,所以在现代农业、军事、救助、运输等领域得到了极为广泛的应用。
Humans have had a long-cherished wish to fly. One of the first aircrafts to be manufactured was a helicopter. Toy bamboo rafts invented in China in the Ming Dynasty can be said to be the prototype of modern helicopters. However, the success of the first test flight of the helicopter was in 1930. The launch of practical value was in 1939. It was not until 1945 that it was actually used as an aircraft. It was later than the ordinary aircraft. Helicopters are not the same as fixed-wing aircraft. Because they can take off and land vertically, they can fly in any direction, they can hover in the air like a chandelier, they do not need a lot of space for takeoffs and landings, so in modern agriculture, Military, rescue, transportation and other fields have been widely used.
