Can 747 break Mach 1?

"Original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 0.99. In addition, Boeing knows one case in which a 747 operated by Evergreen International made an emergency descent at speeds that exceeded Mach 1."

What planes broke Mach 1?

Seventy-five years ago, on October 14, 1947, the Bell X-1 Glamorous Glennis, piloted by U.S. Air Force Captain Charles E. “Chuck” Yeager, became the first airplane to fly faster than the speed of sound (Mach 1). The experimental purpose-built aircraft reached 1,127 kilometers (700 miles) per hour (Mach 1.06).

Can any planes go Mach 1?

No aircraft company would build a jet designed to cruise right at Mach 1. In the transonic speed range (from roughly the high Mach 0.8s to around 1.1), there are many areas of mixed subsonic and supersonic air flow over the airframe, and following the localized supersonic flow there are shock waves.

Do commercial planes break Mach 1?

No they do not break the sound barrier in normal flight. The speed of sound at 30,000 ft (approximately the altitude most airliners fly at) is approximately 678 mph. Most airplanes typically travel at about 400–500 mph.

How fast is 747 to Mach?

The 747 is one of the largest commercial aircraft ever built, and the 747-8 Intercontinental (747-8i) variant wins the race as the fastest commercial plane in service today. This plane is as tall as a six-story building with a top speed of Mach 0.86. That's equivalent to 659.85 mph.

Can The 747 Really Fly Supersonic? - Modern Supersonic Plane

Could a 747 go supersonic?

No. The Boeing 747 was not designed for supersonic flight, though during testing, it was pushed quite close to the sonic speed: Tom Cole, a spokesman at Boeing Commercial Airplane Co., said original flight tests of 747s conducted in 1969 and 1970 took 747-100 models to speeds of Mach 0.99.

Can a 747 go Mach?

The Boeing 747 is a large, wide-body (two-aisle) airliner with four wing-mounted engines. Its wings have a high sweep angle of 37.5° for a fast, efficient cruise speed of Mach 0.84 to 0.88, depending on the variant.

What Mach is the fastest plane ever?

The NASA/USAF X-15 is the fastest fighter jet ever produced. It reached record top speed of Mach 6.72 or 4,520 mph, which is more than five times the speed of sound.

What is the fastest Mach a human has gone on a plane?

The winner of our top 10 – the X-15! Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.

What plane can go Mach 15?

Mach 15 is about 5104.35 meters per second. The only plane that was slated to move that fast was the (unmanned) NASA X-43, which recorded speeds over Mach 10. The X-43A used a rocket booster to get to speed after being dropped out of a B-52. A scramjet engine powered the aircraft.

Can you go Mach 1 underwater?

Water-tunnel tests have already proven that speed can be achieved: In 1997, the Navy tested a supercavitating projectile (illustration above) that reached 5,082 feet per second, becoming the first underwater projectile to exceed Mach 1.

What happens when Mach 1 is exceeded?

When an aircraft exceeds Mach 1 (i.e. the sound barrier), a large pressure difference is created just in front of the aircraft. This abrupt pressure difference, called a shock wave, spreads backward and outward from the aircraft in a cone shape (a so-called Mach cone).

What happens if you fly faster than Mach 1?

Breaking the sound barrier

Once an object exceeds Mach 1, it manages to outrun the sound waves it produces, which creates a sonic boom. The loud crack of a sonic boom is a complication when it comes to supersonic flight.

Is Mach 10 possible for jets?

The most likely answer is a resounding no. Mach 10 speed has never been achieved by a manned aircraft, though, so it has never been tested.

Has a jet gone Mach 9?

Maverick is cautioned not to make the flight—Mach 9 is 6,905.42 mph. The closest a piloted aircraft has come to that speed in reality is the SR-71 Blackbird, which reached Mach 3.3 or 2,193 mph.

Why is supersonic flight illegal?

In the 1950s and '60s, Americans filed some 40,000 claims against the Air Force, whose supersonic jets were making a ruckus over land. Then in 1973, the FAA banned overland supersonic commercial flights because of sonic booms—a prohibition that remains in effect today.

Can Boeing 777 go supersonic?

But can the average commercial airliner reach supersonic or even near-supersonic speeds? According to a retired Boeing 777 and Airbus captain and current airline flight instructor Lim Khoy Hing, the answer is no.

Can a human survive Mach 1?

If human manoeuvre that speed Mach 1(1225 Kph), the air friction will increase the body temperature enormously. It will almost boil the body. The strange symptoms including temporary vision loss, loss of consciousness and weightlessness.

Can a helicopter reach Mach 1?

The average cruising speed of a helicopter is generally less than 160 knots (184 MPH). A fixed-wing aircraft may be as high as 450 knots (517 MPH). There is simply no helicopter that can cross continents at speeds approaching Mach 1 (the speed of sound), but several fixed-wing aircraft have done this.

What plane broke Mach 10 in Top Gun?

“Top Gun: Maverick” features one of the best edge-of-your-seat action sequences of the year as Tom Cruise's Maverick takes the supersonic Darkstar aircraft on an unauthorized test flight, pushing it to reach a speed of Mach 10.

Do bullets break Mach 1?

Bullets break the sound barrier with boring regularity. The speed of sound is roughly 1125 feet per second at standard temperature and pressure (sea level). That speed will vary a bit depending on your elevation, climate and weather conditions, but not much.

What does Mach 3 feel like?

What does it feel like to travel at Mach 3, 15 miles above the earth? Pilots report that, with no view out the window, there's an eerie sensation of motionlessness when cruising in the Blackbird. To fly safely in this harsh, low-pressure environment pilots must wear a full-pressure suit for protection.

Why are 747 being phased out?

But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes. When Boeing confirmed in July 2020 that it would end 747 production, it was already only producing at a rate of half an aircraft a month.
