Magic of wings and flaps

 Have you ever sat near the wings on a plane. Apart from feeling you miss city views, have you wondered why the wings are shaped the way they are, why there are flaps, why they pop or change angles in the middle of flight, is the tip of the wing in up direction for decorative purposes etc.

Neil deGrasse Tyson is good educator.  Airplanes have wings. They hvae mini wings on wings. They also have vertical wings. The top parrt is curved. The bottom part is flat. Air wants to travel as one parcel. The top part of air moves faster to keep up with the bottom part of the air. The faster air going on top of it has lower preassure and air on bottom pushes it out. The faster it moves, the bigger preassure distance between them and it causes lift. 

Well,  that is for easy explanation. The parts of the air has no emotion to stay together as one parcel. It is just that air going on top of the wing has more space to occupy on its way down so the air preassure becomes low on the top. The wings are curved to make air flow around. Engines are causing to move forward with high speed. Wings are causing to move upward or maintain lift with preassure difference. The more bigger the wings are, the more lift they create. Speed is another way. Lift varies with square ofc the spoeed. If speed is doubled, lift is increased by four times.

Flaps play important role in taking off and landing. When the flaps are up, they change surface area and cause lift. As part of take off, flaps on the tail wing moves up and that creates extra preassure to puhs the tail down and moves the nose goes up. The wing is pitched upwards towards the moving air. The plane is going to suddenly pop up and fly from the ground.  As part of landing, the flaps are extended from the body. The broken wing shape causes preassure difference less. 

Pitching up or down or limbing up or down is done with the flaps in the tail. The flaps on wings are used to turn the plane left or right.
