Because they are both use for flying.
Airplane wings are shaped like a bird's wing. They are thick at the front and thin at the back. This form of shape is more aerodynamic.
A bird creates lift by flapping its wings Aircraft move by the air moving over the wings (where as birds move by moving their wings around the air)
Some bird wings are like airplanes wings because the air goes over and under it like a airplane soaring through the sky!
well........ if you look at a shapes of a bird wings it is a bit the same and tht will give you the answer
Because the whole point is for the wings to provide lift. Many designers spent hours watching how bird wings were shaped and how they moved to provide lift or propulsion.
Airplane? What airplane? My paper airplane wings weigh less than 8 grams.
The importance of wings is critical to an airplane, they produce lift that can sustain the airplane in the air.
An airplane with two wings on either side is called a biplane.
Some energy source is required to overcome the unavoidable drag of pushing through the air, to lift the bird or airplane up to flying height, and to give the bird or airplane kinetic energy. Airplanes use propellers or jet engines. Birds use strong muscles in their breasts to flap their wings. In addition, bird wings are hinged, while airplane wings are riged and fixed. The bird uses its strong muscles to push its wings downwards, pushing air downwards, generating lift, and, if the wings are angled properly, also thrust. The big problem then becomes not pushing air back upwards when the bird moves its wings up for the return stroke. They have no teeth and hollow bones
To "plane" means to soar or glide, based on a French word that refers to the position of a bird's wings in flight. Therefore, an airplane is a vehicle that soars through the air like a bird.
They are on the wings
airplane, birds. that's all i came up with so far. ~Karen~
