What is the speed of sound at 30000 feet?
What is the speed of sound at 30000 feet? For example, the speed of sound at 30,000 feet is about 670 miles per hour, but an aircraft must travel at least 750 miles per hour (Mach 1.12, where Mach 1 equals the speed of sound) for a boom to be heard on the ground.
How much was a ticket on the Concorde?
Such speed didn't come cheap, though: A transatlantic flight required the high-maintenance aircraft to gulp jet fuel at the rate of one ton per seat, and the average round-trip price was $12,000.
Is the Concorde faster than a fighter jet?
So, to answer the question, yes, some fighter jets are faster than the Concorde. However, it is important to note that the Concorde was primarily designed for passenger travel, not for combat or aerial maneuvers.
Is Mach 1 supersonic?
These speeds are referred to by Mach numbers. The Mach number is the ratio of the speed of the aircraft to the speed of sound. Flight that is faster than Mach 1 is supersonic. Supersonic includes speeds up to five times faster than the speed of sound, or Mach 5.
Has Mach 10 been reached?
Mach 10 speed has never been achieved by a manned aircraft, though, so it has never been tested. Mach 10 has, however, been achieved by a spacecraft - on November 16, 2004, NASA launched the X-43A, an air-breathing hypersonic vehicle, and was able to reach real Mach 10 while being pushed into the atmosphere.
What is the fastest a jet has ever gone?
The fastest fighter jet ever created was the NASA/USAF X-15. It was an experimental aircraft that resembled more of a rocket with wings but managed to reach a record 4,520mph. The fastest fighter jet in the world today is the MiG-25 Foxbat, with a top speed of 2,190mph, half the speed of the X-15.
Has a 747 ever broken the sound barrier?
Aircraft are put through extreme testing during their certification, but such limits are never intended to be actually faced. The 747 -100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.
Why is supersonic flight banned?
Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.
