Greeting the readers of the channel!
After the Second World War, the reactive aviation began to develop rapidly. It happened in the military and civilian sectors. Military aviation is understandable. Who possessed a powerful and fast fighter, he provided himself with an advantage over the enemy in the likely war. In civil aviation was different. Post-war years, especially 1950-1960s. Considered as the time of hopes for the world and the creative development of humanity as a whole.
At about this time, plans for the creation of commercial liners appeared in the leading countries of the world, which could fly with supersonic speed. This has answered the requirements of the time on the rapid and convenient movement of people between countries and entire continents. So, countries that could then afford the survey data were somewhat: the United Kingdom, France, the USA and the USSR. They all approximately at one time and began steps to create a supersonic commercial aircraft.
If we talk about the UK and France, these countries decided to unite their projects and in 1962. As a result of the merger, it turned out modern at the time and the longest (until 2003) the supersonic aircraft «CONCORDE». The Soviet Union created its supersonic aircraft «Tu-144», which first made his long-awaited flight in 1968. Unfortunately, in 1978, the commercial use of Tu-144 was discontinued for a number of reasons.
And now, go to the unfulfilled American dream. The fact is that this country also created its supersonic passenger liner. But his fate, compared with other such planes of other countries, turned out to be the most unenviable. American
And in the fact that in this aircraft designers decided to apply an innovation: a variable wing geometry. But this significantly increased the weight of the structure. Therefore, this idea had to refuse and apply the usual delta wing to the aircraft, like «Concorde» and «Tu-144». Because of this, the timing of the timing of the aircraft was again delayed. According to the final, the US Senate in 1971 refused to finance the project, as it was considered that he was already unprofitable, and the backlog from the USSR and a joint project of Great Britain and France — completed the implementation of this project. Here, the ecologists were added and concerned about the emissions of nitrogen oxides engines of this aircraft. They were afraid that it hurts the stratosphere and the ozone layer.
However, you need to say about the characteristics of the aircraft. This American airliner would simply be the best in his class. In addition, he would definitely not even two other other competitors: he would be headed above them. It should have been 97 meters, wing span — 43.3 meters, the diameter of the fuselage — 5 meters. Maximum take-off weight
On its flight the plane could take 296 people, which is much more than competitors. But that’s not all. Four Engines General Electric Airplane could develop the maximum speed of 2900 km / h, and there would be a range of 6,800 kilometers. The height of the aircraft is not less impressive — from 18 to 21 kilometers.
And yet, justice for the sake of saying that the closure of this was faithful, both from the financial side and with practical. As shown by the further operation of «Concorde» and «Tu-144» — a supersonic aircraft — the cost luxury. Tickets for it are awesome, and he is not economical. Although it was planned to build from the 1970s to the 1990s. 500 aircraft, but realities showed that such a number of aircraft, in principle, do not need.
Time has shown that with the tasks of transporting a large number of people, and subsonic wide-body aircraft can solve. Behind them and the future. What to hide, by airplanes that overcome the sound barrier, the aerodynamic properties are changed and the flow of flow of the air flow itself. In general, everything is complicated, including after-fleeing service. The project closing strongly hit the company
And today everything. Thank you for reading to the end. We are waiting for your reading of our new articles.
