Aerodynamics


       Everybody thinking and unbelieving about an aeroplane how does it flying in the sky. Even some of the people whom already traveled by aeroplane how does it flying in sky.There are four forces listed


 1.Lift- In this the object(plane) is to be pulled over
the ground.

2. Thrust - In this the Object will pulled in forward direction 

3.Weight- In this the object will be pulled through downwards 

4. Drag- In this the the object will be pulled in backward direction.


The weight is equal to lift and drag is equal to thrust this is the mathematical expression for a plane which is going in a straight and same altitude.If the thrust is greater than drag the speed of the plane is increased.If the drag is greater than thrust the speed of the plane is decreased. Similarly the weight of the plane is greater than lift force the plane will be moving downwards.

If the plane’s lift force is grater than the plane’s weight the aeroplane will be moving upwards. From the above content, the plane moving forward due to the force is given to the engine.i.e,The thrust force is to be given to an engine. Similarly the drag force is given to the plane due to the friction with air. 

If there is no air in earth the plane does not reduce it speed even engine is in off. Many people don’t know about,why the plane pulled that wheels while flying upwards. Due to resisting the friction with air of wheels.If the plane is flying with the friction the expenses of fuel is doubled. The speed of the plane also increases at later. 

The plane is flying upwards due to the source of wings, Plane speed and air. In above three if anyone is missing the flight does not fly at anywhere anytime. First of all watch carefully while the plane is fly over the sky. The top side of the wing is slightly inclined through upwards.This is not visible when we are seeing that wings but known at the time of touching that wings. Why the wings are slightly inclined means, when the air is at high speed the friction is more with the wings of the flight.

        The plane will fly always only the environmental conditions of earth such as humidity, Pressure and temperature of atmosphere. The plane which is moving or pulling in upwards only depends on the relative speed between the plane and air, and the area of wings of the plane. For that only the size and area of the wings are much
high for high load plane. The plane is take off, due to there is no flying power when that is running at slow speed. 

     Thus the plane should always running at particular speed minimum. Because the pulling force toward upwards of the wings of the plane equates the weight of the plane. If the plane reaches low speed from relative speed the plane will moving downwards. The wings are considered only air is to be placed.
