What else can I help you with?
An aeroplane with two pairs of wings on top of each other?
Biplane. Strictly speaking it has ONE wing on top of the other. General usage is to refer to the bit on each side of an aircraft as a wing, but technically the wing is the entire structure from tip to tip.
Why do bi-planes have 4 wings?
Biplanes may appear to have four wings, but one wing is generally refered to the full stretch from left to right. If you look at the top wing of a biplane, it is generally one ininterrupted stretch of (often) wood and fabric, just like a rear wing on an F1 car. A biplane has two of these full-length wings and as such has the 'bi-' prefix. A monoplane is a plane that has only one wing, as 99% of planes today have.

Why do boomerangs fly?
When thrown the top wing of the spin moves in the same direction ,while the wing on the bottom of the spin moves in the opposite direction of the throw. The wing on top is spinning at the same speed as the bottom wing. More air passes under the top wing which lifts the boomerang. The boomerang travels in a circle returning back to the thrower.
What causes lift on an airplane wing?
The air on top of the wing is at a lower pressure than the air at the bottom of the wing so wing is pulled upwards
The energy of air on the top and bottom of a wing generates?
lift. This lift force is created by the pressure difference between the top and bottom surfaces of the wing. The air flowing over the curved top surface of the wing moves faster, creating low pressure, while the air beneath the wing moves slower, creating higher pressure and thus generating lift.
How do airplanes flya?
They way airplanes fly is actually very simple. The wing of an airplane is curved on the top and flat on the bottom. This means that the top side of the wing is longer than the bottom part. When air passes by the wing, some of the air goes on top and some on the bottom. Because the particles of air want to stay together by the law of attraction, the air that passes over the top of the wing moves faster than the air that flows under the wing. This causes a low pressure system to form above the wing and a high pressure system to form below the wing. The higher pressure beneath the wing forces the wing up allowing the air plane to fly. This is also called Bernoullis principle.
How does lift work?
If you are asking about the lift in terms of flying, then this is a simple explanation of it: a wing is curved on top, and straight on the bottom. This means that if the wing starts moving forwards, the air has to move faster over the top of the wing, than underneath the bottom of it, creating an area of lower pressure at the top. This means that the high pressure from the bottom is greater than the pressure from the top, forcing the wing upwards. if this is somewhat awkwardly explained, this site might help better: http://www.allstar.fiu.edu/aero/fltmidfly.htm
How does and aircraft becomes airborne?
There is a lot of explanation: but these are the basics: An airplanes wing is in a special shape it is flat on bottom and Curved on top. When a plane picks up speed the air must get from in front of the wing to the back of the wing. ( there cannot be a vacume!) Because the wing is curved air on top of the wing has to travel faster than the air on the bottom. The laws of physics state that as velocity (speed) increases, pressure decreases. therefore the atmospheric pressure on the top of the wing decreases and the plane rises.
Why is the surface on the top of an airplane wing curved?
The top surface of an airplane wing is curved to create lift. Because of the curve, air has to travel farther across the top of the wing than across the bottom; this creates a low-pressure condition that pulls the airplane into it.
Is the air that travels over the wing of the plane is more dense?
A wing when looked upon from the wing tip is curved at the top and straight along the bottom. So, now there is more surface area on the top in comparison to the bottom. As air rushes along on both sides the air on the bottom is less dense and has a higher pressure compared to the air along the top. Think of the air on top as "stretched out" and therefore thinner than the air on the bottom. This creates a low pressure allowing the high pressure air on the bottom to push up. Ergo, flight.
Can the shape of a wing help obtain lift?
Yes. Wing shape and speed are the two main factors in obtaining lift. The typical wing design has a mostly flat bottom side and a more curved top side. The leading edge of the wing bulges upward on top so that air crossing the wing is pushed upward. The bulge then thins out, sloping downward toward the wing's rear. The result of this difference in shape between the top and bottom of the wing is that there is less air pressure above the wing than below. The greater pessure under the wing pushes upward, creating lift.
