The US air force just successfully tested a new plane that uses a new type of engine called a pulse detonation engine, that is supposed to fly at mach 6. Although the speed of sound varies by conditions, it is about 700 mph so mach 6 would be about 4200 mph. Speeds above mach 5 are called hypersonic. A pulse detonation engine is a pulse jet that creates about 1000 explosions per minute in a high preasure chamber as opposed to a steady normal burn of fuel. It creates a huge amount of power and is very fuel efficient but also creates extreme noise and vibration.
What else can I help you with?
How fast do air planes go?
depends on the plane.
Why do we have planes?
because planes are fast and they can go to place that boats, cars, ect. can not. and for quicker transportation

Planes would only be in my employment future if I had to use them to travel for my job.
How fast did planes go during world war 1?
1 metre per hour
How fast can airpanes go?
Some rocket planes can go as fast as six times the speed of sound. Most military fighter planes do not go faster than twice the speed of sound, and the typical civilian passenger/transport plane goes slower than the sound barrier.
How fast can a future car go?
88mph with timing only
How are planes useful?
planes are used for cargo shipping, passenger shipping, or just sight seeing.
How fast does a rocket car go?
About 300mph. They are not the fastest cars though - unlike with planes, jet cars are faster.
Why streamlining important?
streamlining is important because with out it cars,planes and some boats would go to fast and out of control
Are paper planes fast?
