How fast is a jet going when it breaks the sound barrier?

770 mph
At sea level and standard atmospheric conditions, the speed of sound is 345 meters per second (equivalent to 770 mph or 1239 kph). At 35,000 feet, this could be reduced to around 295 meters per second (660 mph or 1062 kph). It is, of course, not just aircraft that can break the sound barrier and create a sonic boom.

Do jets break the sound barrier?

The sound barrier understood By the 1950s, many combat aircraft could routinely break the sound barrier in level flight, although they often suffered from control problems when doing so, such as Mach tuck. Modern aircraft can transit the “barrier” without control problems.

What happens when a jet breaks the sound barrier?

As this wave-front passes an individual, the sudden pressure differential or change in pressure creates the “sonic boom” that we hear. Anything exceeding the speed of sound creates a “sonic boom”, not just airplanes. An airplane, a bullet, or the tip of a bullwhip can create this effect; they all produce a crack.

Can you break the speed barrier?

The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It’s approximately 770 mph or 1,239 kmh at sea level.

Can jet pilots hear sonic boom?

If you’re WONDERing about how pilots handle sonic booms, they actually don’t hear them. They can see the pressure waves around the plane, but people on board the airplane can’t hear the sonic boom. Like the wake of a ship, the boom carpet unrolls behind the airplane.

Can the pilot hear sonic boom?

Has a 747 ever broke the 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.

Why are there no sonic booms anymore?

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.
