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 ...
The first aircraft to break the sound barrier with a female pilot was an F-86 Canadair Sabre with Jacqueline Cochran at the controls. [1] According to David Masters, [ 2 ] the DFS 346 prototype captured in Germany by the Soviets, after being released from a B-29 at 32800 ft (10000 m), reached 683 mph (1100 km/h) late in 1951, which would have ...
At a speed of about 767 miles per hour, depending on temperature and humidity, a moving object will break the sound barrier. ... This is what it looks like when the Air Force tests its jet engines.
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 set numerous records and was the first woman to break the sound barrier on 18 May 1953. Cochran (along with Nancy Love ) was the wartime head of the Women Airforce Service Pilots (WASP) (1943–1944), which employed about 1000 civilian American women in a non-combat role to ferry planes from factories to port cities.
On August 21, 1961, a DC-8 broke the sound barrier at Mach 1.012 (660 mph/1,062 km/h) while in a controlled dive through 41,000 feet (12,497 m) and maintained that speed for 16 seconds. The flight was to collect data on a new leading edge design for the wing, and, while doing so, the DC-8 became the first civilian jet – and the first jet ...
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."
