The secret is Bernouilli's principle. This says that the faster air flows, the lower its pressure. So we build an aeroplane with wings that are curved on the top and flat on the bottom, ie with a d-shaped cross section. When the plane is pushed through the air by jets or propellers the air will flow across the top and bottom of the wings. BUT the air on top has further to go, because the top of the wing is convex , than the air at the bottom. So it will flow faster to keep up with the air at the bottom. That means, according to Bernouilli, that the air pressure will drop in the faster flowing air at the top of the wing. So the wing will be pushed up by the air at the bottom. Hopefully when the wings are pushed up, the body will go up as well. Or the wings will be ripped off.
What else can I help you with?
Why cannot aircraft fly in space?
An aircraft is designed to fly in 'air' there is no 'air' in space.
Why can't an aircraft fly into the air?
A properly designed aircraft most certainly can fly into the air.
What is the difference between an aircraft and a spacecraft?
Aircraft fly through air and spacecraft fly in space.
Will robots be able to fly?
In a sense, modern commercial aircraft and many military fighter aircraft are already flying robotic devices. Built in computer controls fly many of the airplanes that are in the air at this moment, it's called "fly by wire". Some of the fighter aircraft are so difficult to keep in the air, the only way to actually perform that task without tiring out the pilot is to have the computer manage the control surfaces while the pilot only appears to fly the airplane. As for commercial aircraft, auto-pilot is certainly a robotic function.
Where did the Japanese fly from 1941?
Air fields, and aircraft carriers.
How long does it take to get to mars in an aircraft?
Can't be done. An AIRcraft needs AIR to fly in. There isn't any air between earth and Mars.
What is an air corridor?
An air corridor is a predefined route which a commercial or military aircraft must fly.
What is the definition glider plane?
A glider is an aircraft that does not have an engine. To fly it must be towed into the air by a vehicle or another aircraft.
How jets fly?
The jet is an awesome aircraft that can propel in to the air by aerodynamics and thrust.
Why airplane fly in the sky?
Because AIR is the natural medium for aircraft to travel in.
How do airplanes fly across the world?
The same way they would fly from New York to Los Angeles. If they were attempting to fly around the world this would require in-flight refueling or they will have to stop and refuel.
Do helicopters flyhigher than air planes?
No, fixed wing aircraft fly higher.
