What Mach causes a sonic boom?
What Mach causes a sonic boom? As long as an airplane travels at Mach 1 or faster, it will generate a continuous sonic boom. All those in a narrow path below the airplane's flight path will be able to hear the sonic boom as it passes overhead. This path is known as the “boom carpet.
Can 747 break Mach 1?
The Boeing 747–400 cannot top Mach 1, capped at 988 km/h, or Mach 0.8. The plane cannot exceed Mach 1, because its engines are not fast enough to propel the aircraft forward that fast. This also has to do with the plane's aerodynamics, because it is large and has dihedral wings.
Why is sonic boom illegal?
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.
What is the 1100 mph plane?
Spike Aerospace, founded in 2013 Max Kachoria of NASA, built an 18-passenger supersonic jet with low-sonic boom, fuel efficiency, speeds up to 1,100 mph, and flight times slashed in half. Their current model is the S-512 which can get passengers to cities in a moment's notice: NYC to London: 3 hours.
