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.

Dec 24, 2024 · 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.

4 days ago · A sleek white aircraft became the first independently developed jet to break the sound barrier Tuesday, tearing through the air tens of thousands of feet above the Mojave Desert and a crowd of delighted onlookers. The XB-1 aircraft accelerated to Mach 1.05 within about 11 minutes of taking off, ...

5 days ago · Before today's sound barrier-breaking flight, the XB-1 underwent 11 test flights. The aircraft includes features like an augmented reality system to make takeoff and landing easier and has a long ...

4 days ago · 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. ...

Jan 7, 2025 · The meaning of SOUND BARRIER is a sudden large increase in aerodynamic drag that occurs as the speed of an aircraft approaches the speed of sound.

May 21, 2024 · The sound barrier is a concept developed in the early 20th century, when many scientists believed that the drag on aircraft caused by approaching the speed of sound made it impossible for any aircraft to reach or exceed the speed of sound without being destroyed.

Sound barrier is a phenomenon where sound waves in the air get packed densely ahead of a moving thing (such an aircraft) and form a highly pressurized area there. Sound is vibration in the air, and it goes as sound waves.

We began this chapter by transporting ourselves back to October 14, 1947, and riding with Chuck Yeager as he flew the Bell X-1 through the sound barrier, becoming the first human to fly faster than sound.

NASA is currently researching how to make a quieter sonic boom. They are doing this by shaping thesupersonicaircraft so the wake created by the plane is less pronounced, meaning theboom is more muffled, making a ‘whoomph’ rather than a ‘bang’. …
