just the price of a barrel of oil dropped back that supersonic civil aircraft projects reappear. In addition to some private builders projects, NASA worked longtime on the mastery of the shock wave caused by the supersonic flight. Better, the Agency launched the initial phase of a supersonic jet design, the Quiet Supersonic Technology (QueSST), a device that should validate the tests in the wind tunnel and flight tests. Is a supersonic device without supersonic bang noticeable possible? This is what the researchers want to demonstrate.
According to the researchers, without the “Bang” supersonic flight is possible
the United States finally take their revenge on those Europeans who have managed to design an airliner there where their industrial had wrecked? Exactly 47 years (!) after the first flight of the Concorde, NASA announced its desire to build a supersonic jet. Launched as part of a research over 10 years, the “New Aviation Horizons initiative” program, his QueSST is not the size of a Concorde, but closer to a plane of matter. NASA has released 20 million to Lockheed Martin to carry out the preliminary study of the jet. The American giant will work with GE Aviation for the motor component, but also with the Californian sorting Models Inc., a specialist in the construction of models of blowers. The project team has 17 months to complete this phase of study. The next phase will probably be the construction of a prototype that will verify that the theory is well verified by the facts and that this device does actually not noise cause. For Joe Shin, the administrator of the mission of research, no doubt, “develop, build and test flying a prototype is the next logical step to enable the airline industry to supersonic flight.”
The business jet is the first outlet of this research on the flight “BOOMLESS”
for the time being, the aircraft manufacturers argue counted steps in this direction. The best placed in the supersonic race seems to be Aerion Corporation, the startup of billionaire Robert Bass. It recorded its first orders and has the support of Airbus and its AS2 jet should fly within 5 years. According to its designers, it can fly up to Mach 1.2 “BOOMLESS” cruising so without sonic boom over land and up to Mach 1.5 in high-speed cruise. The cabin can accommodate about 8 luxury seats and departing at slightly less than 55 tons, the aircraft can fly over 8 000 to 9 000 km, depending on the chosen speed. Among other current projects, Russian Sukhoi now leads only the SSBJ project, a project that inherits from the project joint between Sukhoi and Gulfstream in the 1990s. An Englishman, HyperMach was also in the race with SonicStar, an aircraft capable of flying up to Mach 4 case… Thanks to a propulsion hybrid. A hyper-ambitieux project there is pretty much no no news since its launch in 2011.
NASA account first to fly a 1/2 scale model by 2020… If budgets are voted by the next president of the United States.
