Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level , this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h).

2 天之前 · Designs for supersonic airliners began in the mid-20th century, and by the 1970s we had supersonic passenger flight. There was the little-known Russian Tupolev-144 and Concorde, a Franco-British ...

2 天之前 · What is supersonic flight? The Mach number is defined as a plane’s speed divided by the speed that sound waves move through the air. To “break the sound barrier” means to fly faster than the ...

4 天之前 · Boom Supersonic’s XB-1 supersonic demonstrator aircraft during its 11th test flight where it became the first civilian aircraft to fly supersonically since the Concorde.

2025年1月28日 · Boom Supersonic, the American company building what promises to be the world’s fastest airliner, broke the sound barrier for its first time with a test flight in Mojave, California, on Tuesday.

2025年1月29日 · 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. ...

The term supersonic is used to describe a speed that is over the speed of sound (Mach 1). At a normal temperature like 70 degrees Fahrenheit (21.1 °C), the speed needed for something to be traveling at a faster than sound speed is about 344 m/s, 1,129 ft/s, 770 mph or 1,238 km/h.

A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach 1). Supersonic aircraft were developed in the second half of the twentieth century.

2009年5月19日 · Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5. In 1947, Air Force Capt. Charles E. “Chuck” Yeager became the first person to fly an aircraft faster than the speed of sound.

2014年6月25日 · Supersonic flight is one of the four speeds of flight. Objects moving at supersonic speeds are going faster than the speed of sound. The speed of sound is about 768 miles per hour at sea level.
