With this description, it becomes clear that no association between ar 15 ultrasound planes breakin

Sound is a form of energy which is due to solids, liquids, and gases are transferred from one place to another. However, the more we hear the sounds we hear are arriving by air. Whatever the source of the sound, the vibration, impacts to the surrounding air enters, and then set the pressure waves are scattered in all directions. Small portions of these waves hit the eardrum, such as sounds recorded in the human brain.
The importance of this is that the speed of sound in air is the natural reaction against the nuisance factor (vibration source), respectively. Imagine if a car passes slowly through the crowd, people ar 15 who are on the way to your next opportunity will be drawn the way for the car. But if the same car as quickly as the people move, they will no longer limit itself to make its way out in this case, the natural rate of reaction is much less than the speed of the car. Aircraft collisions with air molecules problem with something like that.
Since air molecules Consciousness creatures are not competent to hear and decide the vehicle to go out of its way along, so they are cut, not through the vehicle or a nose Rather through slipstream ahead it moves, however, opening the way to operate a vehicle when the vehicle speed is greater than the normal speed of air waves and the waves are always so ahead of the move.
When the airplane, or any other object balls to move faster than normal air waves, molecules and can not be surprised when your next kill. In these conditions, the density of the air pressure is increased so that the new pressure wave ((shock wave)) in front of the object is formed. The compressed air pressure in the shock wave intensity and its temperature rises proportionally.
Airlines ar 15 that fly faster than the shock wave of sound waves, which is more or less like a boat at sea level is played. However, in comparison with the boat waves that are scattered in a horizontal plane, plane shock waves in all directions (up, down, left and right) are published. However, these waves are much further away from the aircraft, the weaker the Grdnd.ba However, even when they reach the ground relatively high pressure, and if you are into listening to the sound of bombs exploding are heard as a long boom.
The following figure shows how the shock waves of the head and tail of the airplane starts like a broom on the ground forced, ar 15 like the boat Amvaaje sea or the password river. To say that shock waves around the outer surface of the aircraft would come, but, as noted previously, only two of them are the main course. For this reason, the sound breaking the sound barrier usually a pair of Serial hear the explosion.
With this description, it becomes clear that no association between ar 15 ultrasound planes breaking the sound barrier thunder there any other words, not only did not no wall, but the length of time that the plane will fly faster than sound waves continuous acoustic trauma caused to the broadcasting industry. But we only hear their voices from across our area or are close to it, just like the waves caused the ship moved again, just as we are sensible the ship from the beach, which we pass near them .
The cumulative effects of ultrasound on flights and increasing air temperature. Part of this increase in temperature caused by friction and the other part is caused by air density, wind-beating as a bicycle pump would be hot.
Therefore, when, for example, an airplane to fly twice the speed of sound, the air temperature rises to become a serious figure. The problem is that aircraft gradually becomes hot and must be cooled to keep the passengers and crew of thought. At higher speeds from 2.5 to 3 times the speed of sound, the air becomes hot enough to lose his strength aluminum alloys. The stainless steel is that it can be used instead of the alloys because the melting point of aluminum is much higher. The addition of new metals, such as titanium, composite materials in aircraft construction use. In developed countries, which are aircraft manufacturers, the possible use of titanium and its alloys and composite ar 15 materials have been done years of research and testing, as these materials are not only lighter than steel, ar 15 but they show more resistant to high temperatures.
