In addition to books and papers, part of the data cited a brick, YF23 two academic tyrants speak. A genius named Badittrich Cusiman, the pioneer and founder of modern aerodynamics, served in Nazi Germany in the early days and was carved up to Britain after the war. The EST, who wrote aerodynamics in 1953, is now a designated textbook for aviation professionals in higher education around the world. In the first ten years, he led the sweptwing for high-speed aircraft, the flexor flexor seaman tips, seaman fairing design concept, calculation method of wing load ratio after any aspect, this method is still now subsonic based wing design algorithm is one of the second ten years of research; a history of aviation second using flow - detached vortices, which is the basis for the development of advanced fighters until today; the last ten years, studied third hypersonic flow regimes, seaman flexion, created the concept of waverider, todays Galet and DSI is only two by inlet of the primary wave derivatives in theory. At the beginning of the 60s, the two generation fighter aerodynamic characteristics of layout design are still attached to avoid flow and restrain air separation; but for mobility requirements can be used to pursue the angle of attack increases, separation is inevitable. With close coupled canard fixed Swedish SAAB-37 fighter will vortex lift applications, to achieve control of flow separation and utilization of detached vortices has been used widely until today. The application of vortex lift fighter, mainly rely on the air flow from the vortex generator (canard strake) front separating stable vortex, high-speed rotating airflow increases the negative pressure of the wing surface, the vortex intensity increases with the increase of the angle of attack, generate vortex lift large, showed a strong obvious in the slop
