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 1.05 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 ...
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 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 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.
After getting to altitude, Brandenburg opened up the test plane's throttles, accelerating to Mach 1.1, or about 845 mph (1,360 kph) -- faster than the speed at which sound travels.
During this descent Baumgartner set the record for fastest speed of free fall at 1,357.64 km/h (843.6 mph), [2] [12] [5] making him the first human to break the sound barrier outside a vehicle. [ 38 ] [ 39 ] Baumgartner was in free fall for 4 minutes and 19 seconds, a fall time 17 seconds shorter than the record set during mentor Joseph ...
Boom Supersonic’s XB-1 aircraft broke the sound barrier for the first time ever on Tuesday, ushering in a new era of supersonic flight. The jet exceeded Mach 1 after taking off from the Mojave ...
