Question: Can Commercial Planes Break The Sound Barrier?

What is the fastest jet in the world?

Lockheed SR-71 BlackbirdThe Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner.

Key elements of the SR-71’s design made this possible..

Has a car broken the sound barrier?

Thrust SSC holds the world land speed record, set on 15 October 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier.

Can a 747 break 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.

What can break the sound barrier?

The compressed air in front of the plane exerts a much larger than usual force on the plane. There is a noticeable increase in the aerodynamic drag on the plane at this point, hence the notion of breaking through the “sound barrier.” When a plane exceeds the speed of sound it is said to be supersonic.

Why is it illegal to break the sound barrier?

Within the United States, it is illegal to break the sound barrier. … When you pass Mach 1, the plane travels faster than the waves itself and that move across the so-called sound barrier produces a large sound, which is the sonic boom.

Can a sonic boom kill you?

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

Can pilots hear the sonic boom?

No. It is not heard in the aircraft. Originally Answered: Does a pilot hear the sonic boom of his or her own plane when it breaks the sound barrier? Well no, the plane is faster than sound, so the sonic boom sound can’t catch up.

What aircraft can break the sound barrier?

Only two, Tupolev Tu-144 (first flight – December 31, 1968) and the Concorde (first flight – March 2, 1969), ever entered service for civil use as airliners. Fighter jets are the most common example of supersonic aircraft.

At what speed do you break the sound barrier?

about 770 mphU.S. Navy For an airplane to break the sound barrier, it must hit speeds of about 770 mph — when it does that a couple of things happen.
