1881 11, the anniversary of the birth of the famous American engineering mechanics Carmen (1881 - 1963). Carmen was born in Budapest, Hungary. His greatest contribution to mankind pioneered the application of mathematics, mechanics in the aviation, aerospace and other engineering and technical fields, and laid the foundation for the development of modern mechanics, aeronautics and aerospace science, some of the most brilliant theoretical concept to his name to name. The 1911 Carmen left on the flow of fluid in the cylinder after two rows of the periodic vortex-depth research, made a penetrating analysis of this vortex in theory. This is the famous Carmen vortex. Carmen created National Aeronautics and Sciences, and put the college building became fluid dynamics research centers and training bases. Von Karman cultivate a large number of outstanding talents. His students in all five continents, known as "Carmen Cobain. Among them include shoulder scientists and engineers worldwide technology leadership work in outer space. Carmen support his students on rocket propulsion technology research and proved to be able to design a stable and lasting burning solid rocket motor for the first time and Malina. Carmen human life than any contemporary a scientist or engineer. Precisely those aspects of his carefully created, the scientific achievements of the human conquest of the sky is coupled in a long chain, due to his efforts, jets 3000 kilometers per hour, a range of 1,200 km missiles and interstellar rocket became reality today .
