航空工业是高技术、知识高度密集的工业,1980年统计,美国在这一部门从事研究和设计的科学家和工程师占全体人员的7.4%;1965～1975年,美国投入航空航天研究发展的费用,平均每年约50亿美元,占全国研究发展费用的30%左右。航空工业水平实际上代表一个国家的科技和工业发展水平。为了在世界范围内军事上和商业上的激烈竞争中占据优势,各发达国家都投入大量人力物力,强化航空科学的研究和新技术的开发,争先吸收科学技术各方面的新成就,促使航空产品以前所未有的速度更新换代。
Aviation industry is a high-tech and highly knowledge-intensive industry. Statistics from 1980 showed that 7.4% of scientists and engineers in the United States engaged in research and design in this sector accounted for the entire staff; from 1965 to 1975, the United States invested in the development of aerospace research and development, The average annual amount is about 5 billion U.S. dollars, accounting for about 30% of the national research and development costs. Aviation industry actually represents a country’s level of technological and industrial development. In order to gain an upper hand in fierce military and commercial competition in the world, all developed countries have invested a great deal of manpower and resources to strengthen their research in aeronautic science and the development of new technologies, first to absorb new achievements in various fields of science and technology and to promote the development of aviation products Replace with an unprecedented speed.
