Sound Barrier And What Is Sound Barrier
What Is Sound Barrier - the sound barrier, the term is actually a vote to block an inappropriate term to describe a condition for aircraft moving at a certain speed. we hear will be the occurrence of a kind of "hurdle" to the aircraft the aircraft if has reached the speed of sound, but it turns out that's not the case that kind of sound barrier.
to be able to understand this, let us start with the question of an aircraft flying at low speed. by the time the plane was moving forwards, the front part of the aircraft was issued a pressure wave.
pressure wave was caused by accumulation of particles of the air at the time the plane was moving forwards. this pressure wave precedes aircraft was moving forward with the speed of sound. therefore, the speed of sound moves faster than the plane itself.
which as we have said above, the aircraft was ahead with speed. at the time of this pressure wave slide fore preceded the plane, then he is led to the air it is moving smoothly through the surface of the wings plane approaching it.
we just say the plane was flying at the speed of sound now. then the air which different in front of the plane will not accept pressure waves in advance before him, because either the plane or the waves of pressure it piled in front of the wings of the plane.
as a result there was a sort of wave of Yanks, and waves it caused great pressure for the plane. before the plane was flying at the speed of sound or faster than the sound.
then it is expected that a wave of jerking and pressure will form a kind of "hurdle" for the plane, which is a "sound barrier". but it turns out that there are no obstacles to such a case. why? the engineers in the field of aviation has managed to create a pattern of building an aircraft that is capable of tacking this.
we heard a rumbling sound as piled on the when the plane passed through a "sound barrier" was caused by a surge of jerking as we describe above, when that same pressure wave velocity with velocity traveled by plane.
