United plans supersonic passenger flights by 2029

[kafa88]

United States Airlines has announced plans to buy 15 new supersonic aircraft and "return supersonic speeds to aviation" by 2029.Supersonic passenger flights ended in 2003 when Air France and British Airways broke up Concorde.The new Overture is manufactured by Boom in Denver, which has not yet flown a test flight of the supersonic jet.United's deal provides conditions for new aircraft that meet safety standards.


What is a supersonic flight?

Supersonic flight is when slotxo an airplane travels faster than the speed of sound.At an altitude of 60,000 feet (18,300 m), that means flying faster than 660 mph (1,060 km/h).A typical passenger plane might cruise at around 560 mph (900 km/h), but Overture is expected to reach speeds of 1,122 mph (1,805 km/h), also known as Mach 1.7.with that speed When traveling on a transatlantic route such as London to New York will be reduced by half Boom says Overture will be able to travel in 3.5 hours without a plane ride for 3 hours.The Concorde, which entered passenger service in 1976, is faster with a top speed of 2.04 Mach - about 1,350mph (2180km/h).


What challenges are there?

There are two main concerns about supersonic passenger travel: noise and pollution.
Traveling faster than the speed of sound produces a sonic boom that can be heard on the ground like thunder or explosion. It's where Boom got its name.The boom limits where the plane can fly. Usually they had to slow down until they got out to sea. Keep away from people who may be disturbed by loud noises.Boom said it was confident its plane wouldn't make more noise than other modern passenger planes during takeoff, landing and landing. It is also hoped that there will be improvements in the design of the aircraft as the Concorde will reduce and mitigate noise.

The other big problem is fuel consumption.In order to fly above the sound You will need more strength. You will need more fuel,” Boom's chief commercial officer, Kathy Savitt, But she expects Overture to act as "zero carbon plane"Can supersonic travel really be 'sustainable'?Central to Boom's plan is for Overture to use all sustainable aviation fuels (Safs).Dr Guy Gratton, an associate professor of aviation and the environment at Cranfield University, explains, which may take the form of "Luxury biodiesel" is made from everything from industrial waste animal fats. to specially grown high-energy crops

But one big problem is "The world is far from having everything like the capacity needed" to produce enough biofuels to power the entire aviation industry, he said. Boom predicts that the process "Liquid energy", which uses renewable energy such as wind power to produce liquid fuel. will cause scarcity We expect to be able to trade well before it is necessary for our purposes,” explained Boom's Raymond Russell.There are billions of dollars of airline commitment and investment across sectors.”But it is still an industry that needs to be scaled up.Can you suddenly find a huge amount of additional sustainable electricity at a reasonable price?” Dr. Gratton asked.I'm not saying it can't be done. It might be good, but it hasn't done it yet.


Is there a need for a supersonic journey?

Despite the enormous cost of developing the Concorde more than 50 years ago, it was thought to be profitable for British Airways during its final year of operation. Concord is seen as a luxurious way to travel with tickets that cost more than a first class seat on a regular jet.Today, the wealthiest travelers may prefer private jets, Instead of traveling on a first-class commercial plane with the public. The rich can rent compact private jets that fly on demand. straight to and from the airport of their choice Avoiding check-in counters and baggage claim can also save you travel time.

Ms Sawit said Boom's findings suggest that passengers need speed. and faster planes can “Connecting deeper human relationships and building better business relationships”Unlike Concorde, the company expects Overture to make a profit for the airline, even if it sells tickets for the same price. "Regular Business Class Fare" Ultimately, it is up to United to set the price. But would like to see a return on investment of $200 million per plane (£140 million).
