Current passenger aircraft fly at altitudes of 30,000 to 40,000 feet. Virgin Galactic has begun work on the project with Rolls-Royce and Boeing Corporation, but it is not clear when the project will be completed. How much does a plane cost? All the passenger planes in the world at the moment are slower than all the noise, ie "sub sonic". The only supersonic (supersonic) passenger aircraft in human history was the Concorde, which retired in 2003. Virgin Galactic's supersonic passenger aircraft will actually be a "business jet". The buyer will be able to customize the design.
At present, there are jet engines and airframes that can be used to make business jets three times faster than sound. However, the goal of the Virgin Galactic is to build passenger planes that are able to fly and land at existing airports like a normal jet, and reach their fastest speed after reaching the highest altitude. The reason is that although the problem of the sonic boom with this aircraft will be very small, but still due to the friction of the air, its outer structure will become very hot, while the shock waves created as a result of high-speed flight. It will create severe tremors in the aircraft, which it is imperative to reduce and even eliminate completely. It is hoped that despite all these challenges, the aircraft will be flying in the skies of the world by 2040.
