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). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic.

Mar 20, 2023 · Supersonic speed is a term used to describe objects moving faster than the speed of sound, which is approximately 767 mph (1,235 km/h) at sea level. When an object travels at supersonic speed, it creates a shock wave that produces a loud boom known as a sonic boom.
May 19, 2009 · Learning more about supersonic flight helps NASA design aircraft to perform better at supersonic speeds. It can also help in the design of new vehicles used to explore space. Space vehicles fly at supersonic speeds too. Rockets like the space shuttle fly at supersonic speeds after liftoff.
Jul 10, 2013 · The final term we need to understand to talk about supersonic speed is something called the Mach number. The Mach number is the ratio of the velocity of an object relative to some medium and the...
Apr 13, 2023 · As the Cambridge Dictionary reports, supersonic can be defined in quite simple terms: "faster than the speed of sound." This, too, is a little difficult for those who aren't versed in the physics...
May 15, 2024 · Supersonic Flight. NASA is working with its partners to enable new choices for high-speed air travel, starting with commercial supersonic flight over land through the Quesst mission and the experimental X-59 airplane. Even faster flight some day through hypersonic technology is not impossible.
May 1, 2023 · If you wanted to fly a plane at supersonic speeds at lower altitudes, the speed of sound is faster in that warmer air. At 10,000 feet, supersonic flight begins at 735 mph, NASA says.
Jun 25, 2014 · 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.
Oct 23, 2023 · Subsonic refers to any aircraft that is moving slower than Mach 1, meaning it is below the speed of sound. Transonic describes aircraft that are traveling at the speed of sound, usually within a...
