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).
ThrustSSC, Thrust SSC or Thrust SuperSonic Car is a British jet car developed by Richard Noble, Glynne Bowsher, Ron Ayers, and Jeremy Bliss. [1] Thrust SSC holds the world land speed record , set on 15 October 1997, and driven by Andy Green , when it achieved a speed of 1,228 km/h (763 mph) and it became the first and only land vehicle to ...
A supersonic wind tunnel is a wind tunnel that produces supersonic speeds (1.2<M<5) The Mach number and flow are determined by the nozzle geometry. The Reynolds number is varied by changing the density level (pressure in the settling chamber). Therefore, a high pressure ratio is required (for a supersonic regime at M=4, this ratio is of the ...
Supersonic speed doesn’t begin at a fixed point, as temperature, humidity and air pressure all affect how fast an aircraft must go to qualify. According to Boom, a jet must reach around 770 mph ...

The Lockheed Martin X-59 Quesst ("Quiet SuperSonic Technology"), sometimes styled QueSST, is an American experimental supersonic aircraft under development by Skunk Works for NASA's Low-Boom Flight Demonstrator project. [2] Preliminary design started in February 2016, with the X-59 planned to begin flight testing in 2021.
The U.S. Navy test-launched a powerful SM-6 supersonic missile from a container mounted on ... You can see the launch of one the missiles—which accelerates up to 3.5 times the speed of sound ...
Many claims of supersonic speeds were found to be far below this speed when measured in this fashion. In 1942, Republic Aviation issued a press release stating that Lts. Harold E. Comstock and Roger Dyar had exceeded the speed of sound during test dives in a Republic P-47 Thunderbolt. It is widely agreed that this was due to inaccurate ASI ...
