NASA wholly-owned mute supersonic aircraft for the future or for commercial flights

The aircraft will be the latest model for the X-Series and will be quieter than the supersonic aircraft previously designed. Known as the bass flight demonstrator, the aircraft will make its first flight by 2021 if the budget is approved and aircraft research and development can proceed as planned. According to the budget, the aircraft is a validation of noise reduction technology and is promising for commercial aircraft in the future. It enables supersonic travel while eliminating those who can shatter the roar of glass, which is the traditional supersonic aircraft can not be eliminated.

NASA said in a statement that people generally do not like airport noise and do not like the annoying series of shock waves caused by aircraft engine noise. The U.S. government made provisions in 1973 that prohibited civilians from carrying out supersonic flights over the United States. After the self-Concorde supersonic aircraft retired in 2003, no supersonic civil aircraft continued to fly.

Lockheed Martin has already won the project start-up capital to build such a new X aircraft. According to previous reports from Bloomberg, Lockheed Martin plans to design a bass aircraft to meet the 60-65 dB target set by NASA. This means it will be quieter than any current supersonic aircraft.

In a statement, NASA said the goal of the project is to make the supersonic flight unobtrusive to the public, like the thunder of a distant sky, or the sound of your neighbor's door closing outside. NASA is also demanding investments in the research of hypersonic aircraft, which will fly at multiple speeds of sound. According to Space.com, hypersonic aircraft are likely to be used in the military or in space.
