How does a supersonic jet work?
When a jet airplane is flying faster than Mach 1—beyond the speed of sound—the air entering the engines is moving supersonically as well. The job of an engine inlet is to slow incoming air to subsonic speeds before it passes through the engine.
What is a supersonic flight?
supersonic flight, passage through the air at speed greater than the local velocity of sound. The speed of sound (Mach 1) varies with atmospheric pressure and temperature: in air at a temperature of 15 °C (59 °F) and sea-level pressure, sound travels at about 1,225 km (760 miles) per hour.
Why is it important to learn about supersonic flight?
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.
What was the name of the plane that flew at supersonic speeds?
The space shuttle orbiter flies at supersonic speeds during portions of its mission. An airplane called the Concorde was the most notable passenger airplane to travel at supersonic speeds. The Concorde’s maximum speed was more than twice the speed of sound.
What makes a bullet travel at supersonic speed?
A bullet fired from a gun travels at supersonic speeds. This picture shows a bullet and the air flowing around it. The bullet is traveling at 1.5 times the speed of sound. NASA learns about supersonic flight by using small models of aircraft in wind tunnels. Wind tunnels move air over the models as if they were flying.
What happens to the center of pressure in a supersonic plane?
In the reverse direction, an aircraft trimmed for supersonic flight will experience a pitch-up moment from the forward shift in the center of pressure once it slows down, which can stall it or overload the structure. ¹ I could also talk of the center of pressure here, but that would be less precise.
