Lockheed Martin showed a prototype of the X-59 QueSST supersonic aircraft’s construction. The American company is in the final stages of building a prototype supersonic aircraft.
The QueSST program (Quiet SuperSonic Technology) involves the creation of technologies that, in the long run, will reduce the volume of supersonic aircraft. As a result, it will perform supersonic flights over the inhabited part of the land, which is currently prohibited by international rules.
The shape of X-59 reduces the loudness of a sonic boom reaching the ground to that of a gentle thump if it is heard at all.
In February 2016, Lockheed Martin received a contract from NASA to pre-design a supersonic aircraft to fly until 2020. On April 2, 2018, NASA signed a contract with Lockheed Martin for $ 247.5 million for the development, construction and delivery of the aircraft at the end of 2021.
According to the project, the demonstrator of the “quiet” supersonic aircraft will be made with a single engine.
The length of the aircraft will be 28.7 meters, with a wingspan of 9.0 m.
Among other design solutions that will reduce the volume of the aircraft is an elongated sharp nose.
In 2020, GE Aviation supplied NASA with F414-GE-100 turbofan engines designed for installation on the X-59 QueSST.
F414-GE-100 is based on the engine with afterburner F414-GE-400.
The latter is serially installed on twin-engine deck fighters F / A-18E / F Super Hornet.
