Can a passenger jet break the speed of sound?
To break the speed of sound, the aircraft would have to fly at about 574 knots of true airspeed, at an altitude of 35,000 feet. What you can do, while you wait for supersonic commercial flight to become a thing again, is look at the flight data on the entertainment display in front of you.
Can a passenger jet go supersonic?
A supersonic transport (SST) or a supersonic airliner is a civilian supersonic aircraft designed to transport passengers at speeds greater than the speed of sound….High costs.
| Aircraft | Concorde | Boeing 747-400 |
|---|---|---|
| Passenger miles/US gallon | 14 | 91 |
| Litres/passenger 100 km | 16.6 | 3.1 |
Is there a jet that can go the speed of sound?
Most modern fighter aircraft are supersonic aircraft, but there have been supersonic passenger aircraft, namely Concorde and the Tupolev Tu-144.
Can passenger planes break the sound barrier?
The sound barrier understood By the 1950s, many combat aircraft could routinely break the sound barrier in level flight, although they often suffered from control problems when doing so, such as Mach tuck. Modern aircraft can transit the “barrier” without control problems.
Has a 747 ever broken the sound barrier?
As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which it is traveling.
Why is it illegal to break the sound barrier?
It’s against the law. Within the United States, it is illegal to break the sound barrier. When you pass Mach 1, the plane travels faster than the waves itself and that move across the so-called sound barrier produces a large sound, which is the sonic boom.
Do passenger planes fly faster than the speed of sound?
A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85\% of the speed of sound. Generally speaking, the higher the aircraft flies, the faster it can travel.
How fast is Hyper Sonic?
Hypersonic missiles travel at Mach 5, five times the speed of sound while maneuvering in the atmosphere. That’s faster than 3,800 mph.
Why are supersonic commercials illegal?
But at speeds greater than Mach 1, air pressure disturbances around airplanes merge to form shock waves that create sonic booms, heard and felt 30 miles away. Then in 1973, the FAA banned overland supersonic commercial flights because of sonic booms—a prohibition that remains in effect today.
Why is a sonic boom two bangs?
The “boom” is experienced when there is a sudden change in pressure; therefore, an N-wave causes two booms – one when the initial pressure-rise reaches an observer, and another when the pressure returns to normal. This leads to a distinctive “double boom” from a supersonic aircraft.
Why did the plane fail to exceed the speed of sound?
Since airspeed is the difference between ground speed and wind speed, the plane failed to exceed the speed of sound. Guys…. ground speed =/= air speed. The flight going 801mph was ground speed, not air speed.
Are SuperSonics the latest dreams of jet travel?
Alas, the latest dreams are no more real than previous ones. The obstacles to fast jet travel remain very high, and if anything they’re getting higher. First, supersonics—planes that fly at least Mach 1, typically Mach 2 or faster.
How fast do airplanes fly?
In an era when everything else is accelerating, airplanes are actually flying at slower speeds than they used to… Specified cruising speeds for commercial airliners today range between about 480 and 510 knots, compared to 525 knots for the Boeing 707, a mainstay of 1960s jet travel. Why?
Is ground speed the same as air speed?
As multiple Twitter pundits and articles pointed out, ground speed is not the same as air speed. Since airspeed is the difference between ground speed and wind speed, the plane failed to exceed the speed of sound. Guys…. ground speed =/= air speed.
