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.
Boom Supersonic’s XB-1 aircraft climbed over 35,000ft on Tuesday before accelerating to Mach 1.1 speed and then breaking the sound barrier in three high-speed runs spanning 35 minutes over the ...
The sound barrier was first broken on Oct. 14, 1947, according to the U.S. Air Force. That's when Capt. Chuck Yeager and the Bell X-1 rocket-propelled aircraft broke the sound barrier.
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 news of a straight-wing supersonic aircraft surprised many American experts, who like their German counterparts during the war believed that a swept-wing design was necessary to break the sound barrier. [4] On 10 June 1948, Air Force Secretary Stuart Symington announced that the sound barrier had been repeatedly broken by two experimental ...
At a speed of about 767 miles per hour, depending on temperature and humidity, a moving object will break the sound barrier. It was not until World War II, when aircraft started to reach the ...
In 1983 Richard Noble had broken the world land speed record with his earlier car Thrust2, which reached a speed of 1,019 km/h (633 mph). The date of Andy Green's record came exactly a half century and one day after Chuck Yeager broke the sound barrier in Earth's atmosphere, with the Bell X-1 research rocket plane on 14 October 1947.
Herbert Henry Hoover (May 18, 1912 – August 14, 1952) [1] was an American NACA experimental test pilot who, on March 10, 1948, became the first civilian and second person to break the sound barrier, [2] a feat for which he was awarded the Air Medal "for meritorious achievement while participating in aerial flight."
