从1873年人类乘气球首次升空到飞机的发明,直至到现在乘宇宙飞船到其它天体上进行科学考察,人类在征服宇宙的道路上经历了几次飞跃。在这方面有几个名词是经常提到的,即航空、航天和宇航。 航空 航空是人类在大气圈范围内,在地球引力作用下,凭借各种航行工具,在空中从地球的一地到另一地。1902年,莱特兄弟首次驾机试飞成功,打开了人类航空历史崭新的一页。航空运输是速度最快、路径最短、适应性强、效率高的一种运输方式。各种飞机、飞艇
From the first human launch of a balloon on a plane in 1873 until the present scientific exploration by spacecraft to other celestial bodies, human beings have undergone several leaps in the conquest of the universe. Several terms are often mentioned in this regard, that is, aviation, aerospace and aerospace. Aeronautics and Aviation are human beings in the atmosphere within the sphere of gravity under the influence of the Earth, by virtue of a variety of sailing tools in the air from one place on Earth to another.
