一、航空的历史(一)我国古代的航空理想我国的航空理想由来已久,人们随着生产力发展和社会的进步,在不断地探索着腾空原理,并为实现这一航空理想而不懈努力。早在公元前2205—2158年(大禹时代)已发明了船帆和船舵,懂得了利用空气动力。公元前722—481年(春秋时期)的公输般和墨翟,曾“削竹为鹊,成而飞之”。公元9—23年(王莽时期),有人用鸟羽试验过飞行。公元25—220年(东汉时期)的著名科学家张衡,也制造过木鸟。公元265—316年(晋朝时期)的葛洪发现了鸟的滑翔原理。公元618—907年
I. History of Aviation (I) The Aviation Ideal of Ancient China The aviation ideal of our country has a long history. With the development of productive forces and social progress, people are constantly exploring the principle of vacating and making unremitting efforts to realize this aviation ideal. As early as 2205-258 BC (Dayu) has invented the sail and rudder, know the use of aerodynamics. 722-481 BC (Spring and Autumn Period), the public transport and ink Zhai, had “cut bamboo as a magpie, into the fly.” In 9-23 AD (Wang Mang period), someone used Toba to test the flight. Zhang Heng, a famous scientist from AD 25-220 (Eastern Han Dynasty), also made wooden birds. GE Hong 265-216 (Jin Dynasty) Ge Hong discovered the principle of bird gliding. 618-907 AD
