NASA and Lockheed Martin have moved one step closer to creating the “quiet” X-59 passenger aircraft – a team of engineers has completed its wing. CNBC journalist Michael Shiitz drew attention to this.

The next milestone in developing the X-59 project will be the unification of the three main sections (fuselage, wing and airframe) into a single structure in the spring of 2021.

The American company Lockheed Martin is developing a demonstrator of the “quiet” passenger aircraft X-59 within the QueSST project framework. The QueSST program implies the development of technologies that in the future, will make it possible to make supersonic aircraft quiet enough so that they can perform supersonic flights overpopulated land. Today international regulations prohibit this.

The designers expect to reduce the noise level of the X-59 using a specially designed airframe designed to reduce the intensity and amount of shock waves generated during flights at supersonic speeds.

According to the project, the single-engine demonstrator’s length of the “quiet” supersonic aircraft will be 28.7 meters. He will receive the usual vertical keel and horizontal rudders for manoeuvring at low flight speeds. Among other design solutions to reduce noise, an elongated sharp nose can be distinguished, blocking the pilot’s entire view.

In August, the American company GE Aviation put NASA’s first two F414-GE-100 turbofan engines installed on the X-59 demonstrator. It is a modification of the F414-GE-400 afterburner turbofan engine, serially used in the F / A-18E / F Super Hornet twin-engine carrier-based fighters.

In October, NASA and Lockheed Martin postponed the flight tests of the aircraft from late 2021 to 2022. At the same time, the start date for ground tests was shifted to the summer of 2021. At the same time, NASA assured that the aircraft flight test data required to create a regulatory framework for supersonic aviation would be transferred to the International Civil Aviation Organization and the US Federal Aviation Administration in 2027, as originally planned.
