Research On The New Aerodynamic Layout Design Of Supersonic Cruise Transport

Airliner has been the pursuit of speed and economy，hope that both high-speed aircraft flight, andlow fuel consumption, however, this is a contradiction.Since when aircraft flying at high subsonic,theshock will produce a local,and shock resistance increases rapidly as the flight Mach numberincreases,thereby reducing greatly the aircraft’s lift-drag ratio K,for the supersonic flight of aircrafteven greater impact,therefore,to enable the aircraft to have good aerodynamic characteristics ofsupersonic cruise,one of key design feature is to reduce aircraft flying supersonic shockresistance.Supersonic cruise capability,refers to the aircraft with the engine afterburner withoutopening the case, it can do supersonic flight continuously.The current non-supersonic cruise fighters,afterburner to do when the only supersonic flight, and fuel consumption will jump severaltimes,supersonic flight time of only a few minutes, and also the poor mobility,but with supersoniccruise capability of the aircraft, it can overcome the above shortcomings.For civil transport aircraft,supersonic cruise flight time can be shortened,increased comfort,it can also makes the world more andmore closer,promote the development of world trade.After this theoretical study of aircraft design,andwith reference to foreign supersonic cruise aircraft,on this basis to explore new supersonic cruisetransport aircraft aerodynamic layout programs, First design an initial shape of the aircraft,then thenumerical simulation software to analyze the aerodynamic characteristics, according to the results ofthe analysis, the initial appearance there is a problem for this problem, we propose a new andimproved design and re-modeling, meshing with the improved design requirements,pneumaticcalculation of the final comparative analysis of the aerodynamic characteristics ofsupersonic cruise transports the two design shape, control and the proposed design specifications, theconclusions obtained improved aircraft aerodynamic performance is better.
