Does a silent aircraft have less difficulty breaking the sound barrier?

Question

If the aircraft engines are incredibly quiet, the build up of sound shock waves would be less intense, then breaking through it would be easier, isn't it?

Answer 1

the amount of sound the engines make is not important for breaking the sound barrier. What you want is the plane to be extremely aerodinamic and the amount of thrust that your engines can put out.

Answer 2

The term sound barrier was actually a result of the sudden decrease in thrust and increase in noise that a propeller engine experiences as it approaches mach 1. The propeller blades go rapidly and progressively supersonic from the tip and they just don't work at supersonic speeds.

Next problem is loss of control. In WWII pilots who dived to fast tended to become part of the scenery, they found that the controls stiffened up and they couldn't pull out of the dive. Some escaped by winding in pitch trim. Early on they called this compressability and they found that trans-sonic shock waves were building up on the control surfaces.

So there is an association with engine, or at least propeller noise.

But a fine understanding of aerodynamics is the most important secret to exceeding the speed of sound. Modern supersonic aircraft pass through the sound barrier without any adverse effects, it's just a number. Concorde actually reduced throttle above M1 because the supersonic shock wave in the engine inlet gave an effective increase in EPR and thus thrust.

Answer 3

Engine noise and the 'sound barrier' have nothing to do with each other..
The degree to which an aircraft will produce a 'boom' has do to with the shape and size of the aircraft than anything else.
Larger aircraft will produce a larger shock wave and hence a louder 'boom'

Answer 4

What you're listening to once you pay attention a sonic growth is the marvel wave that's vacationing with the airplane.The marvel wave is shifting accross the floor on the comparable speed because of the fact the airplane so which you pay attention it in user-friendly terms whilst it passes over you. If it passes over somebody some miles from you first, they'll pay attention the growth until now you will. particularly you will oftentimes pay attention 2 booms. One is the bow wave, or air compressing in front of the airplane and the different is the marvel wave created by potential of the wings. in case you will think of correct to the final time you heard one it exchange into 2 beats, greater like kaboom than basically growth. That growth growth is the two marvel waves inflicting the air to pass all a thank you to the floor. yet interior the airplane, that is amazingly quiet fantastically at very severe altitudes.

Answer 5

No, not at all. The "sound barrier" has nothing to do with the amount of sound the airplane makes.

"Sound barrier" is an archaic term for the sharp increase in adverse forces that occurs at the point at which the motion of an airplane through the air compresses the air in front of it to a critical degree. At one time it was believed that it would not be possible for an airplane to fly that fast or faster.

The speed of unitary compressibility under standard atmospheric conditions is about 740 MPH. Aerodynamic experiments with bullets, which naturally fly faster than sound, and with bullet-like objects after the Second World War, revealed the appropriate methods for exceeding the speed of sound.

Aeronautical engineers no longer use the term "sound barrier" and it has passed into the realm of popular jargon.

Answer 6

the sound of the plane has nothing to do wit the shockwaves that the plane must pass to break the sound berrier. the "waves" are caused by the aircraft moving thru the atmosphere.
