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.

2025年1月29日 · A sleek white aircraft has become the first independently developed jet to break the sound barrier. The XB-1 aircraft accelerated to Mach 1.05 within about 11 minutes of taking off Tuesday. ... The Boom Supersonic’s XB-1 aircraft breaks the sound barrier, Mach 1, during a test flight Tuesday, Jan. 28, 2025, over the Mohave Desert, Calif ...

2025年1月28日 · Boom Supersonic, the American company building what promises to be the world’s fastest airliner, broke the sound barrier for its first time with a test flight in Mojave, California, on Tuesday.

2025年1月29日 · An aircraft developed by Boom Supersonic became the first independently funded jet to break the sound barrier this week. The XB-1 aircraft accelerated to Mach 1.05 at about 35,000 feet during a test flight Tuesday in the same Mojave Desert airspace in California where Charles “Chuck” Yeager was the first person to break the sound barrier in 1947. ...

2025年1月28日 · It marks the first time an independently developed jet has broken the sound barrier, Boom Supersonic said, and the plane is the "first supersonic jet made in America." The sound barrier was broken ...

2025年1月28日 · At one point, however, XB-1 briefly broke the sound barrier once again. XB-1 surpassed Mach 1 yet again a few minutes later before landing 11:54 PM EST after a total flight time of 33.49 minutes.

2025年1月28日 · Ten months after its long-delayed first subsonic flight took place last March, Boom Supersonic’s prototype test plane, the XB-1, broke the sound barrier today three times during its 12th...

2024年12月24日 · Sound barrier, sharp rise in aerodynamic drag that occurs as an aircraft approaches the speed of sound and that was formerly an obstacle to supersonic flight. If an aircraft flies at somewhat less than sonic speed, the pressure waves (sound waves) it creates outspeed their sources and spread out

70 research in supersonic flight and the breaking of the sound barrier models were used, each one with different locations of the pressure taps. A total of thirteen pressure tap locations, seven on the upper surface and six on the lower surface, were employed (for the reader who is counting, the seventh model had only one tap).

2023年10月23日 · Essentially, supersonic flight means any type of flight where an aircraft travels faster than the speed of sound. NASA's Edward Haering, a researcher studying sonic booms, describes it as...
