A British company is developing a supersonic passenger plane

According to the company, the plane will be twice as fast as the Concorde - a flight from Brussels to Sydney will take only 5 hours - and it will be much more economical and environmentally friendly

Recently, the company Reaction Engines Ltd from Oxford, UK, which deals with the development of propulsion systems in space, announced that it intends to develop a supersonic passenger plane. The supersonic plane which will be able to reach Mach 5, a maximum speed of 4,000 kilometers per hour, will be twice as fast as the European Concorde that has gone out of service.

According to the plan, the new plane will have a longer structure and narrower wings, and will resemble a missile more than the passenger plane we know today. With a planned length of 143 meters, the plane will be twice the size of an Airbus A2 and will have room for 380 passengers who will each part with $300 (£6,900) for an economy class flight.

The aircraft, named A2, will be able to enter service in 25 years. If the estimates come true, it will be the first man-made object that cruises at such speeds in the Earth's atmosphere for extended periods. Although there were man-made vehicles that flew through the atmosphere at such speeds, they were usually rocket-powered aircraft, and their flight range was relatively short.

According to Alan Bond, "The A2 was designed so that it would leave Brussels National Airport and fly at a subsonic speed of 0.9 over the Atlantic Ocean, and at a speed of Mach 5 over the South Pole and along the Pacific Ocean towards Australia."

Because of the great heat generated at such speeds, the plane would have no windows. Instead, passengers will see on the seat in front of them images of the landscape captured by cameras outside the plane.

The plane is designed to be much more environmentally friendly than any other plane and this is because for the purpose of producing its energy it will use liquid hydrogen and not fossil fuel as is customary today.

Bond adds and says, "Our work proves that this is possible, now the world must decide if it wants it."

  1. to the stag,
    My friend, it seems to me that you confused me with the person who wrote "Looks like a mistake to me"!

  2. to N. in search of wealth,
    1) "Mach" is a term for the speed of sound. The speed of sound in air is around 300 meters per second, which is about 1100 km per hour. At sea level, if I'm not mistaken, the speed is about 330 meters per second, while as you go higher in the sky, the speed of sound decreases. Now if you think about it (and consider ), you will find that Mach 5 (five times the speed of sound) will actually be less than 5000 km/h necessarily and even in the region of 4000 km/h considering the exceptional height that will be required to fly at such speeds.
    2) Regarding space - you don't really think that you can easily throw a heavy and big monster, do you? It is likely that achieving such a flight speed involves more complex propulsion systems and of course more fuel. In addition, a more aerodynamic design of the plane probably creates more spaces that cannot be used.
    3) A supersonic boom is created when an airplane (or any other body) moves at the speed of sound and this happens when it increases speed and crosses Mach or when it decreases speed and drops to subsonic speed, i.e. 1000 km/h or simply less than Mach 0.9, let's say at altitude Not much, so it is recommended that the plane maintain a speed of Mach XNUMX over the Atlantic Ocean when leaving the airport.

  3. Because there are so many problems with these planes, they will make drainage points on every continent with huge airports. So this plane will simply make a connection between continents and within the continents they will use normal planes (which will depart from those huge airports to normal airports). So, etc. Today there is a connection As with almost any flight from continent to continent, it will save time.
    post Scriptum
    A flight to Australia is around 20-25 hours...

  4. "The supersonic plane that will be able to reach Mach 5, a maximum speed of 4,000 kilometers per hour"

    It seems to me that Mach 5 is around 5,000 km/h and not 4,000.... And how is it that the plane will be twice as big as an Airbus A2 but will only have room for 380 passengers?? What will all this space be wasted on? And how will the plane be able to fly over populated areas at any speed So high, have they forgotten the supersonic boom problem that caused so many flight restrictions on Concorde?

  5. From a technological point of view, all the best, but from an applied point of view... the Concorde stopped flying commercial flights.
    I assume that at some point it will be used for military aircraft, but not civilian.

  6. Dear Ami Bachar no less.
    Surely there will be places that would be worth flying to on this plane (if money doesn't play a role for us)
    But from Israel to Turkey or from Britain to Europe, most travelers would prefer to save money.
    I imagine that by then Europe will be networked with high-speed trains that are simple, fast and cheap to travel on.
    I am not going to invest my unnecessary billion dollars in this project.
    Good Day

  7. Dear Mr. Sabdarmish,
    It seems to me that no matter how we spin it - getting from Europe to Australia in five hours is something amazing. Today, as far as I understand, such a trip can take an average of almost 40 hours (for the regular passenger) including the necessary stops along the way.

  8. What has changed since the days of the failed Concorde? Are the changes so significant as to justify the production and marketing of such an aircraft? I think not.
    To remind you, the Concorde was not successful due to several reasons, including:
    The loud noise and the supersonic boom prevented consent to its landing in populated areas.
    The time to prepare the passenger for the flight, including the security check, which, if added to the flight time, reduces the efficiency achieved. For example, a flight that currently takes four hours will be an hour longer on the plane, but the saving is not one in four, because if we add another two hours before the flight and an hour after the flight, then it is four hours compared to seven hours, which does not seem like a significant saving, and if we add to that both the high price and the convenience The part of the aforementioned plane, it doesn't seem to me that it will be successful.

  9. First time I hear that liquid nitrogen can be used as fuel. Sounds strange to me, maybe it means some kind of nitrogen compound? Can anyone elaborate on this?
