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.
The sound of a sonic boom depends largely on the distance between the observer and the aircraft shape producing the sonic boom. A sonic boom is usually heard as a deep double "boom" as the aircraft is usually some distance away. The sound is much like that of mortar bombs, commonly used in firework displays. It is a common misconception that ...
The programme was highly ambitious for its time, aiming to produce an aircraft capable of a speed of at least 1,000 miles per hour (1,600 km/h) during level flight, and involved a very high proportion of cutting-edge aerodynamic research and innovative design work. Until 1945 all work on the project was undertaken with a high level of secrecy.
XB-1 became the first American-made private supersonic jet to fly faster than the speed of sound as Boom Supersonic works toward building a fleet of supersonic jets for commercial air travel.
This is the first time in history that a land vehicle has exceeded the speed of sound. The new records are as follows: Flying mile 1,227.985 km/h (763.035 mph) Flying kilometre 1,223.657 km/h (760.345 mph) In setting the record, the sound barrier was broken in both the north and south runs. Paris, 11 November 1997.
