The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible.
Through the NACA program, he became the first human to officially break the sound barrier on October 14, 1947, when he flew the experimental Bell X-1 at Mach 1 at an altitude of 45,000 ft (13,700 m), for which he won both the Collier and Mackay trophies in 1948. He then went on to break several other speed and altitude records in the following ...
In the late 1950s, following the breaking of the sound barrier, first by experimental aircraft, then military aircraft, a supersonic passenger aircraft was thought feasible. By the early 1970s however, opposition led to bans on commercial supersonic flight in Sweden, Norway, the Netherlands, West Germany, Switzerland, Ireland, Canada and the ...
The pictures demonstrate the amazing visual effects that occur as military aircraft punch through the sound barrier and travel faster than sound itself. 11 photos of America's fighter jets ...
The World War II fighter pilot ace, who became the first person to fly faster than the speed of sound in 1947, has died. Chuck Yeager, 1st to break sound barrier, dies at 97 Skip to main content
She became a Soviet Air Forces pilot in 1963, and in 1964 was admitted as a military test-pilot. Later that year (June 10), [5] she broke the sound barrier in a MiG-21. She entered the military reserves in 1978 and then joined the Antonov Design Bureau as a test pilot. At Antonov, she set ten flight records on the Antonov An-22 turboprop.
The origin of the Hartman effect had been a mystery for decades. If the tunneling time becomes independent of barrier width, the implication is that the wave packet speeds up as the barrier is made longer. Not only does it speed up, but it speeds up by just the right amount to traverse the increased distance in the same amount of time.
On 26 August 1963 she flew an English Electric Lightning T4 to Mach 1.6 (1,262 mph) after convincing the Air Minister to let her fly it with Squadron Leader Ken Goodwin as her check pilot, and so became the first British woman to break the sound barrier. She also established by this flight a world air speed record for women. [5]
