   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.

   May 4, 2023 · May 4, 2023. Sharing is Caring. 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 ahead of it.

   sound barrier. The sound barrier refers to the sudden increase in aerodynamic drag and other undesirable effects experienced by an object moving through the air at speeds close to the speed of sound, approximately 343 meters per second or 1,235 kilometers per hour at sea level.

   What is a sound barrier?

   • Today, we know that the sound barrier is the sudden increase in aerodynamic drag that happens when an object approaches the speed of sound — also known as Mach 1. It’s not a physical or solid barrier. The moment an aircraft’s speed exceeds the speed of sound, it is said to have broken the sound barrier.

   When did sound barrier come into use?

   • The term came into use during World War II when pilots of high-speed fighter aircraft experienced the effects of compressibility, a number of adverse aerodynamic effects that deterred further acceleration, seemingly impeding flight at speeds close to the speed of sound.

   How does a sound barrier work in physics?

   • As the speed of the object increases to the sonic velocity (the local velocity of sound waves), these sound waves begin to pile up in front of the object. If the object has sufficient acceleration, it can burst through this barrier of sound waves and move ahead of the radiated sound. What is a sound barrier in physics?

   • October 14, 1947: Chuck Yeager Breaks the Sound Barrier. Today, fighter jets routinely achieve speeds faster than the speed of sound, but there was a time when scientists questioned whether the increase in aerodynamic drag as an aircraft approached that threshold would prohibit such a feat.
