What is the sound barrier?

The sound travels like a wave through the media such as air, liquid and plasma. In the air, the speed that the waves travel is determined by atmospheric conditions, so the speed of the sound may vary depending on the temperature. The audio barrier is a concept developed at the beginning of the 20th century, when many scientists believed that the thrust on the aircraft caused by access to the speed of sound prevented any aircraft to achieve or exceed the speed of sound without being destroyed. Thanks to the brilliant and often daring pilot of the day, the concept of the enemy sound barrier was eventually refuted and the plane now routinely breaks the sound barrier when it reaches supersonic speed. If you want to give a general idea, many scientific publications indicate the speed of the sound at 742 miles per hour (1194 kilometers per hour) based on StTePlot Andard 32 degrees Fahrenheit (0 degrees Celsius.) But as the temperature moves up, the speed of the sound barrier increases.

originalThe problem to the concept of the sound barrier is the result of propeller technology. As the aircraft approaches the speed of the sound, the movement of the propeller becomes disturbing sound waves, causing turbulence and reducing the aircraft performance. Many innovators in the early aviation seemed clear that the engine was sufficiently powerful to act against the propeller problems and continue to allow the aircraft profit to be too large and hard to work first.

Adventure penets have not yet liked the concept that there has been a sound barrier that prevents even greater speed, and many have tried to prove that the barrier could be safely interrupted by achieving sound speeds through extremely risk dives to increase speeds to increase speeds that increase speed. Many early attempts ended in fatal accidents because aircraft technology could not handle speed dives and pilots could sufferTo disappear with steep diving and lose control of the plane.

Advances in aircraft design have led to a significant improvement in aircraft control and performance at high speed. Until the 1940s, engineers developed an improved tail, which included a wide horizontal fin to allow more lift and control. The first officially renowned sound barrier turning was made on October 14, 1947, Captain Air Force Capt. Chuck Yeager. Yeager, a well-known test pilot, used a highly advanced aircraft called Bell X-1 to reach 807.2 mph (1299 km / h) and finally broke the sound barrier. Other sources are attributed to another George Welch test pilot, with the interruption of the barrier days before, but because no US officials were present, his flight is officially discounted.

In modern times, the supersonic speed is a common ability in many varieties of aircraft. Breakrál sound barrier ceased to be an important event, although interest was mixed again at the end of the 90s.Arrier 50 years after Yeager flight. The concept of breaking the barrier for some time was one of the main focal points of aviation, which led to modern inventions such as a jet engine. The success of innovation and boldness over what looked like scientific security has proven to be inspiring for many and restored the idea that any barrier can be interrupted by courageous.
