The development experience of the Concorde and why the Concorde was retired

<> Concorde.

There are two reasons for retirement, one is poor economics. The Concorde can be fully loaded with tons of fuel at one time, consume tons per hour, and have a high fuel consumption rate. With a maximum fuel range of more than 7,000 kilometers and a maximum load range of 5,000 kilometers, the Concorde could barely cross the Atlantic due to its short range.

Flying, and not being able to fly across the Pacific Ocean, limits the range of its use. The Concorde has a small passenger capacity and high operating costs. Thus reducing its economy.

The second is that the noise is too loud during take-off and landing, so that most countries in the world do not allow it to land; The second is due to the sonic boom generated by supersonic flight.

They are restricted from flying at supersonic speeds over land as large as Zheng.

There are two reasons for the retirement of <> Concorde, one is the poor economy. The Concorde can be fully loaded with tons of fuel at a time, and it consumes tons every time it is trapped, and the fuel consumption rate is relatively high. With a maximum fuel range of more than 7,000 kilometers and a maximum load range of 5,000 kilometers, the Concorde could barely fly across the Atlantic Ocean and not across the Pacific Ocean, limiting its range of use.

The Concorde has a small passenger capacity and high operating costs. This reduces the economy of the remainder. The second is that the noise is too loud during take-off and landing, so that most countries in the world do not allow it to land; Second, because supersonic flight produces a sonic boom, it is restricted from conducting supersonic flight over the continent.

The main cause was the crash of Concorde airliner AF4590 on July 25, 2000. But it wasn't that there was anything wrong with the Concorde itself, but that it was crushed by a debris dropped by the famous pit machine DC-10 (nicknamed DailyCrash-10) during takeoff, causing a puncture and a tire fragment hitting the fuel tank**.

For specific details, please pay attention to the famous air crash show "Air Crash Investigation" S14E7. At the same time, you can learn about a series of other famous cases of DailyCrash-10 through the program.

Accident: First of all, the main cause of the grounding was the Air France Flight 4590 crash on July 25, 2000. At that time, an Air France Concorde was taking off from Paris-Charles de Gaulle Airport when a thin piece of metal on the runway cut its tires, and the tire fragments pierced the fuel tank, eventually causing the plane to crash.

This incident caused all 109 people on board to die, making everyone doubt the safety of the Concorde. In fact, the tires of the Concorde have always been one of its Achilles' heels, and the Concorde has been operating for many years, and tire bursts occur almost every year.

In addition, the 911 incident in the following year made people around the world panic and did not dare to take planes, and the recession of the international civil aviation industry made the cost burden of the Concorde, which had high fuel volume, high investment and low revenue, even higher.

However, there is news from abroad that in 2019, the Concorde will have the opportunity to reappear! In addition, an American aircraft manufacturing company recently announced that they will build a supersonic passenger plane that is faster and cheaper than the Concorde, not only does it take only 3 hours and 24 minutes to fly from New York to London, but even the ticket price is only 1 4 of the Concorde!
