Although engineers are currently working on creating hypersonic models of civil aircraft, there are problems preventing this from happening.
One of the main ones is material technology that can withstand high temperatures and pressures due to high speed. It is also important to create special engines: a hypersonic aircraft will need one universal or several at once. They should provide flights in subsonic, hypersonic, supersonic mode.
In addition, during the commissioning of such aircraft, problems may arise due to noise and environmental pollution.
The main challenge is to ensure the safety of the hypersonic aircraft. They are difficult to control and fly at high speeds.
The cost of creating a hypersonic passenger plane would also be very expensive. And this, among other things, will require public funds, as commercial companies cannot do this on their own.
Only one of the advantages of hypersonic aircraft can be distinguished. This is high speed. For example, such a plane from New York to London will fly in just an hour.
To date, the experimental development of such aircraft is carried out by several organizations at once. Among them are Boeing, Hypersonix Launch Systems. According to the first of these, the first hypersonic civil aircraft may appear 20-30 years later.
