Supersonic Flight

In 1943, according to the requirements of the US Air Force headquarters, Theodore von Kaman claimed that the implementation of supersonic aircraft could be achieved using the appropriate skills and tools. The fear of breaking the "tone barrier" is that in 1947 Captain Jaeger skipped bell X - 1 for a few seconds at a speed slightly above Mach 1, a well - known and long - awaited sonic boom (caused by impulses When it created, it was finally canceled. The pressure change due to departure from the aircraft provides music to scientists participating in this historical moment, but the present nightmare of supersonic aircraft designers in the 21st century [8].

Over 10 years since the last flight of SuperSonic Concorde, NASA invested $ 2.3 million in eight projects trying to overcome commercial supersonic flight obstacles. The goal of the new job is to make the supersonic flight more green by reducing altitude launches and reducing roaring sounds. This is a very big report generated by shock waves of aircraft flying faster than sonic speed. More than a decade ago, the Human Genome Project provided the first blueprint of our genetic code, opens the doors to the future, allowing individual medical interventions for each patient's genetic makeup. Today, programs like human protein maps not only define DNA that defines our bodies but are further expanded to find building blocks, especially proteins, that paralyze us (or sick) It is.

Although there are many interrelated reasons, TL / DR expressed dissatisfaction with the introduction of ultrasound in the 1970s - built a big SST before making technology more efficient, and destroyed business of supersonic development As the case speed increases, major aerospace companies are focusing on improving efficiency. Fortunately, the technology and business incidents merge, and the resurgence of supersonic is finally coming. Within 10 years since the Jet era began, a supersonic transport (SST) project began in Europe, the Soviet Union, and the United States. Unlike most jet aircraft projects, the SST project is government driven and its requirements are set by the Cold War and not practical economics. Technical miracles, economic interests of airlines are not realistic.

After the withdrawal of Concord Supersonic Transport (SST) more than 10 years ago, faster aviation flight may become reality again as aerospace engineers proceed to supersonic flight without sound boom. Supersonic airliners that do not need prosperity can fly on land, but Concorde is limited to sea flight. NASA sponsors quiet "low boom" demonstration aircraft - quiet supersonic technology (QueSST) designed by Lockheed Martin. After implementing feasibility studies and making efforts to better understand the nation's maximum permissible noise level, the QueSST project aims to produce aircraft that produce relatively soft ham, not a big boom.
