Has a 747 ever broken the sound barrier?

As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.

Can a 747 break sound barrier?

Key. While aircraft are put through extreme testing during their certification, these are never intended to be actually faced. The 747-100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.

Do commercial planes break sound barrier?

Although Concorde and the Tu-144 were the first aircraft to carry commercial passengers at supersonic speeds, they were not the first or only commercial airliners to break the sound barrier.

What jet broke the sound barrier?

All that changed on October 14, 1947, when Yeager flew the X-1 over Rogers Dry Lake in Southern California. The X-1 was lifted to an altitude of 25,000 feet by a B-29 aircraft and then released through the bomb bay, rocketing to 40,000 feet and exceeding 662 miles per hour (the sound barrier at that altitude).

Does the 747 fly over the speed of sound?

Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach . 92. It is very rarely flown at this speed due to the increased fuel burn required. Most modern jets fly around 80% of the speed of sound, Mach .

Has a 747 ever broken the sound barrier?

Can an a380 break the sound barrier?

Not only did the aircraft break the sound barrier, but it also maintained stable supersonic speed for over two minutes, before the engines started overheating.

Does a bullet break the sound barrier?

In fact, bullets can move fast enough to break the sound barrier. Contrary to what the name might suggest, the sound barrier is not an actual wall or barrier. Rather, it is the hypothetical limit to the speed an object can travel before it exceeds the speed of sound.

Has a car broken the sound barrier?

ThrustSSC is a British-designed and built World Land Speed Record car. ThrustSSC holds the current World Land Speed Record which was set on October 15, 1997, by accomplishing a speed of 763 mph. By doing so, the supersonic car became the first land vehicle to officially break the sound barrier.

How long would it take to fly around the world at Mach 3?

Mach 3. If a plane flew at Mach 3 without stopping to refuel, it would take 11 hours to circumnavigate the earth.

Can airplanes go 700 mph?

Flyers have been wowed by quick 5-hour and 15 minutes long flights from New York to London and impressive 700 mph-plus speed readings. On a Boeing 777! Not since the Aerospatiale-BAC Concorde — capable of cruising at twice the speed of sound — has any commercial airliner been able to sustain supersonic performance.

Can commercial planes fly 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.

Can a Boeing 777 break the sound barrier?

The Boeing 777-200 reportedly reached ground speeds of 745mph, almost breaking the sound barrier, 761mph, during its transatlantic journey.

Can you fly a 747 upside down?

The scene, a Hollywood masterpiece of special effects, has people asking can an airliner fly upside down. The answer is yes for a “little” bit! Unlike military fighters, commercial planes do not have the engine power for sustained inverted flight and rely on lift from the wings.

Can a Boeing 787 break the sound barrier?

"Fair winds and following seas" ‒ a Virgin Atlantic's Boeing 787-9 Dreamliner reached a thrilling speed of 801 mph while flying over the United States. While this ground speed seemingly leaves behind the speed of sound (767 mph), the jetliner did not, in fact, magically turn supersonic.

Why do we no longer hear sonic booms?

Why don't we ever hear sonic booms any more? Noise abatement regulations halted supersonic flight (by civil aircraft) over U.S. land. The Concorde could still take off and land here because it broke the sound barrier over the ocean, but it's no longer in service.

Is it illegal for a plane to break the sound barrier?

Within the United States, it is illegal to break the sound barrier. The Federal Aviation Administration regulations are quite clear: "No person may operate a civil aircraft in the United States at a true flight Mach number greater than 1" except in certain, very limited conditions.

Did the Budweiser rocket car break the sound barrier?

While it has been claimed that the Budweiser Rocket did briefly break the sound barrier, it could not gain any official titles because standard ground speed record regulations measure an average speed over a measured distance (either one kilometer or one mile (1.6 km), depending on the particular sanctioning body's ...

What's the fastest street legal car?

Do guns shoot at the speed of sound?

To put that in perspective, it's amazing to realize that bullets travel over twice the speed of sound! If you shoot a gun at a target several yards away, it's easy to think of bullets traveling in a straight line. In fact, over very short distances, bullets do more or less follow a straight path.

Do guns make a sonic boom?

Most bullets make small sonic booms when flying through the air, which to our ears sound like a loud, distinct “crack!” For the Pentagon's special forces, that makes it hard to be sneaky about what they're shooting.

How quick is the speed of sound?

If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second.

Which plane is bigger 747 or A380?

Airbus A380 vs Boeing 747

The biggest difference between the two is size as the A380 is certainly much bigger than the 747. The Airbus A380 has a wingspan that is 15m longer to that of the 747. It is also about 50% heavier than the 747 even when empty.

Do commercial planes fly faster than the speed of sound?

A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85% of the speed of sound. Generally speaking, the higher the aircraft flies, the faster it can travel.

Do airplanes have a speed limit?

Yes, there are lots! Below 10,000 feet above sea level (ASL), all aircraft are restricted to 250 knots (nautical miles per hour). A limit of 200 knots is required when aircraft are within 10 nautical miles of the airport and when they are less than 3,000 feet above the ground.
