How Fast to Break Sound Barrier?
The answer is 761 mph.
The sonic boom is the sound associated with the shock waves created whenever an object travelling through the air goes faster than the speed of sound. The propagate at the speed of sound itself, so if you’re standing still on the ground and an aircraft flies overhead at supersonic speeds, you’ll hear a very loud bang as the waves reach you. How fast does an object need to be going to create a sonic boom?
In theory, it only takes to be travelling at around Mach 1 – which is about 767mph (1,225km/h) at sea level. In practice though, it’s actually quite difficult for an object to travel that fast in level flight without exceeding its structural limits first!
Why is It Illegal to Break the Sound Barrier
It is illegal to break the sound barrier because it creates a sonic boom. A sonic boom is a loud noise that can be heard for miles around and can damage buildings and injure people. Sonic booms are created when an object travels through the air faster than the speed of sound.
The speed of sound is about 1,225 kilometers per hour (km/h). When an object goes faster than this, it creates a shock wave that makes a sonic boom. The problem with breaking the sound barrier is that the sonic boom is so loud, it can damage buildings and injure people.
In some cases, the sonic boom has been known to cause windows to shatter. That’s why it’s illegal to break the sound barrier in most parts of the world.
How Fast Do You Go to Break the Sound Barrier?
On October 14, 1947, U.S. Air Force pilot Chuck Yeager became the first person to fly faster than the speed of sound. He was flying the experimental rocket-powered Bell X-1 aircraft when he reached a top speed of about 700 miles per hour (1,127 kilometers per hour). Since then, many other pilots have flown faster than the speed of sound in various types of aircraft.
The Concorde supersonic airliner could fly at speeds up to 1,350 mph (2,170 km/h). Today’s military fighter jets can exceed Mach 2—or twice the speed of sound. So how fast does a plane have to be going to break the sound barrier?
It depends on a few factors, including the temperature and humidity of the air. But in general, an object must be moving at a minimum velocity of about 767 mph (1,233 km/h) to break the sound barrier.
Can Military Jets Break the Sound Barrier?
Yes, military jets can break the sound barrier. The term “sound barrier” is actually a bit of a misnomer, as there is no definitive line or “barrier” that separates supersonic from subsonic speeds. Instead, the sound barrier is more like a speed limit that aircraft cannot exceed without special modifications.
Breaking the sound barrier is a major accomplishment for any aircraft, and it requires a lot of power and energy. Military jets are some of the most powerful machines ever built, so it’s not surprising that they are able to reach these high speeds. In fact, many modern fighter jets are designed specifically to fly at supersonic speeds and perform aerial maneuvers that would be impossible at lower speeds.
The exact speed at which an aircraft breaks the sound barrier depends on many factors, including its weight, shape, and altitude. Generally speaking, however, most military jets can reach Mach 1 (the speed of sound) or higher. Some of the fastest jet fighters in the world can even exceed Mach 2 or 3 in short bursts!
Is It Legal to Break the Sound Barrier?
Yes, it is legal to break the sound barrier. There are no laws prohibiting it. In fact, there have been many people who have broken the sound barrier, both in aircraft and on foot.
The sound barrier is simply a point where the speed of sound waves traveling through the air becomes faster than the speed of the object generating them. So when an object moves faster than the speed of sound, it breaks the sound barrier and creates a sonic boom. A sonic boom is a loud noise that results from the shock waves created by an object travelling through the air at supersonic speeds.
Sonic booms can be extremely loud, up to 140 decibels, and they can cause damage to nearby buildings and other structures. So while there are no laws against breaking the sound barrier, doing so can be dangerous and destructive.
Has a 747 Ever Broken the Sound Barrier?
Yes, a 747 has broken the sound barrier. On August 29th, 1973, a Boeing 747-100SR operated by Japan Airlines broke the sound barrier while descending from 41,000 feet. The aircraft was carrying no passengers and only had a crew of four on board.
The event occurred over the Pacific Ocean near Hawaii.
What Happens When You Break the Sound Barrier
Conclusion
On October 14, 1947, U.S. Air Force pilot Chuck Yeager became the first person to fly faster than the speed of sound. The achievement came just a few years after the Wright brothers’ first powered flight and marked a major milestone in aviation history. But how fast does it take to break the sound barrier?
It turns out that there is no single answer to this question. The speed of sound varies depending on the medium through which it is traveling. For example, it travels faster through solids than liquids or gases.
In air at sea level, the speed of sound is about 768 miles per hour (1,126 kilometers per hour). To reach Mach 1—the point at which an object is moving at the speed of sound—an aircraft must travel at about 767 miles per hour (1,125 kilometers per hour). However, due to factors such as air temperature and humidity, the actual speed of sound can be slightly higher or lower than this figure.
As a result, an aircraft may reach Mach 1 without even realizing it! Breaking the sound barrier is an impressive feat, but it doesn’t mean that an aircraft can suddenly fly twice as fast. Instead, once an aircraft reaches Mach 1, it can continue to accelerate until it reaches its maximum velocity.
For most commercial jets, this top speed is around Mach 0.85—around 630 miles per hour (1,014 kilometers per hour).
