钱学森（1911～）,中国现代杰出的科学家,世界著名的火箭专家。因其对中国航天事业所作的杰出贡献,被誉为“中国航天之父”。 1934年,风华正茂的钱学森在上海交大机械工程系毕业。当年就考取了清华大学公费留学生,并选择了飞机设计专业,到大洋彼岸去实现自己科学救国的理想。从1935年赴美至1955年回国,钱学森在美20年,以卓著的研究成果,被他的导师、世界气体力学大师冯·卡门赞为“美国火箭技术领域最伟大的天才、最出色的火箭专家”。钱学森与F·J·马林纳合作的《远程火箭的评论与初步分析》,奠定了地地导弹和探空火箭的理论基础;他与导师冯·卡门提出的高超音速流动理论,为空气动力学的发展奠定了基础;以他和冯·卡门命名的卡门一钱学森公式被用于高亚音速飞机的气 Qian Xuesen (1911 ~), a distinguished modern Chinese scientist and a world famous rocket expert. Because of its outstanding contribution to China’s aerospace industry, known as “the father of China’s space.” In 1934, the flourishing Qian Xuesen graduated from Mechanical Engineering Department of Shanghai Jiaotong University. In that year, Tsinghua University passed the examination of overseas students, and chose the aircraft design profession, to the other side of the ocean to achieve their ideal of saving the country by science. From 1935 to the United States to 1955 to return home, Qian Xuesen in the United States for 20 years, with outstanding research results, by his mentor, von Karman of the world master of gas mechanics as “the greatest genius in the rocket technology in the United States, the most outstanding rocket expert”. Qian Xuesen and FJ Mariner cooperation “long-range rocket reviews and preliminary analysis,” laid the ground-based missiles and sounding rockets theoretical basis; he and mentor von Carmen proposed hypersonic flow theory, aerodynamic The development of science has laid the foundation; the Carmen-Tsien-Sen formula, named after him and von Karman, is used for the gas of high subsonic aircraft
