Supersonic Dream: Problems of Supersonic Transport and the Concord

What is the difference between supersonic flight and subsonic flight? The terms "supersonic" and "subsonic" are used to denote the speed of movement at Mach, where "supersonic" is used for velocities between 1 and 5 Mach, "subsonic" is used for Mach 1 (Smith, 2009, 2) When the airplane fly at supersonic speed, it fly faster than sound. The main difference between supersonic aircraft is the design principle. The most important consideration in manufacturing a supersonic aircraft is the air current. Management of the air current is particularly troublesome as the aircraft approaches sound speed. The faster the airplane moves, the harder it is to move the aircraft into the air.

In order to understand the importance of the onshore market for supersonic transport, we have to step back and learn the lesson of history. Since the reunification of the Association in 2003, the traditional view is that supersonic transport is not commercially feasible. Ultimately, Concorde suffered great losses during its 27 years of work and demanded that the subsidies be injected to even equal the French and British governments. However, the special deficiencies of Concord are well understood - and more generally independent of the viability of supersonic aircraft. At maximum takeoff weight of over 400,000 pounds, Concorde is a fuel requirement that requires the use of afterburner to achieve 2 Mach cruise speed. Only 14 companies are used and its design has never been iterated to adopt new technology.

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.
