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.
The X-1 aircraft #46-062, nicknamed Glamorous Glennis and flown by Chuck Yeager, was the first piloted airplane to exceed the speed of sound in level flight and was the first of the X-planes, a series of American experimental rocket planes (and non-rocket planes) designed for testing new technologies.
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. It was not until World War II, when aircraft started to reach the ...
After Bell Aircraft test pilot Chalmers "Slick" Goodlin demanded US$150,000 (equivalent to $2,050,000 in 2023) to break the sound "barrier", the USAAF selected the 24-year-old Yeager to fly the rocket-powered Bell XS-1 in a NACA program to research high-speed flight.
The Cougar was the first jet to break the sound barrier in Argentina. [35] One aircraft (serial 3-A-151) is on display at the Naval Aviation Museum (MUAN) at Bahía Blanca, while the other was sold to a customer in the United States and subsequently lost in an accident on 31 October 1991. [36]
The aircraft has already achieved Mach 0.95—or 95% of the speed of sound; if it blows past that sonic barrier as planned the flight will go a long way toward justifying the faith that three ...
The first, the Bell X-1, became well known in 1947 after it became the first aircraft to break the sound barrier in level flight. [7] Later X-planes supported important research in a multitude of aerodynamic and technical fields, but only the North American X-15 rocket plane of the early 1960s achieved comparable fame to that of the X-1.
