bernellis principle == The principals of flight are no different from a jet than a propellor plane or a glider. The only differences is that the jet is usually designed to fly faster so it's design has to take into account compressible aerodynamics that result from flying close to or above the Speed of Sound. The jet engine operates differently than propellor engines but it's jot is to produce thrust to propell the aircraft forward. And jet engines are more powerful, more economic and/or able to operate above Mach 1 (or the speed of sound). [There is another question here somewhere that explains how a jet engine operates.] The science and engineering equations are all the same. That is why a Russian supersonic passenger jet looks just like an American or a British jet. Custermen
Most cruise at around 500 MPH.
Cruising speed: 528km\h for 1900D
Human beings. We have no wings, so we use airplanes to fly around.
Don't be so stupid..
mach 3 that means three times the speed of sound
Airplanes have motors because they need to fly somehow they can't just have pop-up wings and say, "Up Up and Away!!!!" so they could fly you retard so they could fly you retard so they could fly you retard
humming birds fly so fast because they are so fast
Air planes fly in the stratosphere. Sorry, i didnt give the info of why they fly..im so dumb
The fastest fighters in WW1 flew about 130 mph.
They are streamlined and have powerful engines.
Because cats do not have the capability to fly airplanes.
Airplanes need to generate lift in order to take off and fly. The way they do this is to go fast enough on the ground so that the air passing over the wings generates lift in accordance with Bernoulli's principle. When sufficient speed is attained to generate the necessary lift, the plane will fly.
