The sound barrier is the increase in drag and other problems that aircraft encounter when they approach the speed of sound. Learn how the term was coined, what challenges it posed for propeller and jet engines, and who broke the barrier in 1947.
May 4, 2023 · A noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution.
Sep 30, 2017 · Learn about the historic flight of the Bell X-1, the plane and the pilot who achieved supersonic speed for the first time. Find out the challenges, the methods and the legacy of this aviation milestone.
Jun 18, 2024 · Learn what the sound barrier is, how it affects aircraft performance, and who were the first to break it. Find out the speed, temperature, and factors that influence the sound barrier and the sonic boom.
Feb 16, 2017 · Langley was essential in helping the military to muscle through the sound barrier. The dial would be turned even higher as Langley’s “hypersonics” research ignited, ultimately leading to experimental craft capable of flight at several speed-of-sound multiples.
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 · The X-1 was an experimental aircraft designed to explore the aerodynamics of flight near the speed of sound. On October 14, 1947, Chuck Yeager became the first pilot to fly supersonic and break the sound barrier in this bullet-shaped rocket plane.
