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.
Sep 30, 2017 · A booming thunder roared across the clear skies of the Mojave Desert on Oct. 14, 1947, as U.S. Air Force Capt. Chuck Yeager nudged an experimental rocket-powered plane faster than the speed...
Mar 11, 2002 · Any discussion of what happens when an object breaks the sound barrier must begin with the physical description of sound as a wave with a finite propagation speed.
Oct 13, 2021 · On October 14, 1947, Chuck Yeager and the Bell X-1 proved the sound barrier was surmountable and ushered in an era of experimentation that continues today.
Oct 13, 2022 · Seventy-five years ago, U.S. Air Force Captain Charles E. “Chuck” Yeager piloted the Bell X-1 Glamorous Glennis to become the first airplane to fly faster than the speed of sound (Mach 1).
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.
Oct 23, 2023 · Partly based on research by a British project to create an aircraft that could break the sound barrier, Bell Aircraft and various U.S. government organizations collaborated to produce the Bell...
Feb 16, 2017 · Breaking the Sound Barrier. NASA. Humans delight in speed. History reveals ever more engineered acceleration: a transition from competitive running on two legs to auto racing on roads, from horse-drawn locomotion to high-speed train travel, from transcontinental aerial treks to space-station shuttle launches.
Nov 24, 2009 · U.S. Air Force Captain Chuck Yeager becomes the first person to fly faster than the speed of sound.
An object traveling through the air causes sound wave energy (air) to pile up along a conical line (like the bow wave of a boat) called a wave-front. As these waves pile up, a very large pressure difference exists across the wave-front, which is called a shock wave.
