HOW AIRPLANES FLY ...

   

            
 The purpose of this page is to provide an overview of how Airplanes fly. 

            

There is no big deal to understand how Airplanes fly.

Here is simplest way i will tell .

It is so easy understand how airplanes fly.

So Basically For Flying of Airplanes  Some Basic Fundamental Laws Applied.

1.    Bernoulli's Principle.
2.    Newtons Laws of Motion.
3.    Aerodynamic Forces .

 Aerodynamic Forces  : Four Forces Act on an Airplane when it is flying.

      

•   Lift       :  Lift force  (L) generated by the airplane wings & acting upward                                            direction.
• Weight   :  Airplane weight (W )  & acting downward direction.  
• Thrust    : Thrust force (T) generated by the airplane engines & acting forward                                    direction. 
• Drag       : Drag force (D) caused by air resistance.  

          
 Bernoulli's Principle : Bernoulli's principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. Fast moving air equals low air pressure while slow moving air equals high air pressure.

So That's why Lift force causing Airplane to fly.

 Newtons Laws of Motion : Sir Isaac Newton proposed three laws of motion in 1665. These Laws of Motion help to explain how a planes flies.

• If an object is not moving, it will not start moving by itself. If an object is moving, it will not stop or change direction unless something pushes it.
• Objects will move farther and faster when they are pushed harder.
• When an object is pushed in one direction, there is always a resistance of the same size in the opposite direction.

In Nutshell I  can Say ,

Airplanes are constructed such that the airflow pattern around wing generates lift, thereby enabling them to fly. By help of Bernoulli's principle.

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. 

So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

The airflow in turn is produced by the forward motion of the plane relative to the air. 

This forward motion is produced by engine thrust, delivered by way of propeller engines or air-breathing engines (turbines). 

Airplane engines produce thrust by accelerating the airflow in the rearward direction.

This backwards acceleration of the airflow exerts a "push" force on the airplane in the opposite direction, by Newton's third law, causing the airplane to move forward.
