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.

4 天之前 · 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 …

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

4 天之前 · 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 ...

3 天之前 · 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. ...

音障 （英語： Sound barrier），是一種 物理 現象。 當物體（通常是航空器）的速度接近 音速 時，將會逐漸追上自己發出的 聲波。 此时，由于机身对 空气 的压缩无法迅速传播，将逐渐在飞机的迎风面及其附近区域积累，最终形成 空气 中 壓力 、 温度 、 速度 、 密度 等物理性质的一个突变面—— 激波 （Shock Wave，又译冲击波、骇波或震波）面。 激波的形成是 超音速 飞行的典型特征。 激波面将增加空气对 飛行器 的阻力，這種因為音速造成提升速度的障礙俗稱為 音障。 …

2017年2月16日 · 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.

音障（Sound barrier），是一種物理現象。 當物體（通常是航空器）的速度接近音速時，將會逐漸追上自己發出的聲波。 此时，由于机身对空气的压缩无法迅速传播，将逐渐在飞机的迎风面及其附近区域积累，最终形成空气中压强、温度、速度、密度等物理性质的 ...

2017年9月30日 · 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 of...

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.
