The back of the supersonic passenger planes was closer to reality with the announcement that NASA will fund the project demonstration aircraft of low noise.And when it comes to low noise of supersonic aircraft the main reference is the sonic boom, the almost explosive noise associated with shock waves created when a plane breaks the sound barrier.
The Concorde could only get through the sound barrier when it was flying over the sea, due to the risk of breaking Windows and causing other serious accidents. But this is a important limiter and can make a difference in the economic viability of the aircraft.
X-Planes Series are build to advance space travel.
The design of supersonic aircraft will be the first in a program called new horizons aviation, in which NASA intends to build several “X-planes”, or planes of the future.

For this first project was selected a team led by Lockheed Martin Aeronautics, which should prepare the preliminary design of the QueSST technology (Quiet Supersonic Technology, or silent supersonic technology).
The project will describe a supersonic test piloted plane that is capable of creating what the Agency calls “supersonic pulse” reference to the sound of a heartbeat, replacing the Sonic burst of high destructive potential.

“The development, construction and test flight of an X-plane supersonic quiet will be the next logical step on our way to let the industry decide to open the supersonic travel for the public,” said Jaiwon Shin, project administrator.
Lockheed Martin will take 17 months to complete the design of the aircraft with QueSST technology, including the design itself of the plane, the flight requirements and all specifications, including validations in the wind tunnel, so that the program can walk to a prototype stage.
Expected test model will fly around 2020.
