How planes break the sound barrier?

In order to move faster than sound, an aircraft must produce more lift than drag. One of the most straightforward ways to do this is to fly at a very steep angle, known as a high-elevation angle of attack. A perfectly flat or slightly downward-sloping aircraft will have no lift at all. To increase lift, a pilot will fly at an angle that is steeper than a perfectly flat line. The closer an aircraft is to the horizon, the higher the angle of attack

How planes break the sound barrier in real life?

The sound barrier is a point in air where the speed of sound is equal to the speed of the air flowing over an aircraft. It’s not the plane itself that breaks the sound barrier, rather the sudden increase in air pressure and temperature caused by the high-velocity airflow over the aircraft. At the sound barrier, air over the nose of the plane has enough energy to create a shock wave. The air pressure increases at the nose of the plane, and then quickly drops at the tail

How does a plane break the sound barrier?

A typical commercial aircraft traveling at around Mach 0.75 — around 875 miles per hour — generates a sound pressure level of approximately 150 dB, or a “whooshing noise” heard from as far away as two miles away. To put that in perspective, a jet engine at takeoff produces a sound pressure level of 140 dB, while a chainsaw produces about 110 dB. A Boeing 737 will travel at around 330 km/hour which is about half the speed of sound, about 550

How do planes break the sonic barrier?

The sound barrier is the speed at which sound travels. In other words, sound needs to exceed a certain speed in order to create a noticeable disturbance in the air. And, since sound is a wave, the faster the object that is generating the sound, the faster the sound wave needs to travel in order to reach your ears. In order to break the sound barrier, an aircraft needs to travel at a speed greater than the speed of sound.

How does a plane break a sound barrier?

A plane that breaks the sound barrier generates extra pressure waves that are much larger than sound waves created by objects traveling at a lower speed. The greater pressure compresses the air (increasing its density), which generates more lift. The more lift a plane can generate, the faster it can fly.
