Lockheed Martin X-59
Low-boom flight demonstrator
The Lockheed Martin X-59 QueSST (for "Quiet Supersonic Transport") is a technology test vehicle commissioned by NASA and currently under construction for the development of a quiet , supersonic passenger aircraft.
In February 2016, NASA signed a preliminary contract with Lockheed Martin to develop a supersonic test aircraft . A critical design review took place in autumn 2019 , which confirmed the validity of the assumptions of the draft, which was followed by approval for final assembly in December 2019. In January 2020, NASA released a photo showing the aircraft's wing structure in its mounting frame.
Because of the design of the long front fuselage, the cockpit of the X-59 is relatively low and offers no view of the front for the pilot. Instead, an external vision system (“eXternal Vision System”) displays an image of the airspace in the direction of flight on a screen.
