How Airplane Flies?

In this article we try to simplify the science answer the question: how airplane fly?

What are the forces affect airplane during flight?

There are 4 main forces on object during flight they are:

• Thrust: is the force that propels a flying machine in the direction of motion. Engines produce thrust.
• Drag: is the force that acts opposite to the direction of motion. Drag is caused by friction and differences in air pressure.
• Weight: is the force of gravity. It acts in a downward direction—toward the center of the Earth.
• Lift: is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.

Simply, what is the secret makes the airplane fly?

If we try to put the answer in simple form, we can say: as a result of engine thrust the air flows across the wing and because of special shape of the wing (the airfoil shape) it generates enough lift force to carry the airplane
