Wings

Now we're gonna learn about the airplanes parts:

Today we'll learn about the wings.

Here we have the basics airfoils, in the up side there is more area and ind the low part there is less area it makes sustenance. Thats why and aircraft take off. 

                     The wings also can have diferent shapes, here we have the basics ones:

ogival 

The wings also have some mobil parts as the flaps(7,8), the ailerons(2,3),  the air brakes(10) and attack border(5,6),winglets(1) and spoilers(9).

The flaps help to reduce speed and turn the airplane,the aileron gives sustentation and reduce speed the air brakes stop the aircraft when landing on,attack border gives sustentation and pilots use when they are taking off and landing, winglets reduce the combustible used and spoilers crash the sustentation and stop the airplane

In conclusion the wings are the most important part of an airplane, if the aren't wings the airplane couldn't fly, also they are so simple but they have a lot of complements that make them to be sophisticated.
