             The Evaluation of Aeroplanes

Introduction :

        Hey friends! SO, in today's post let us saw in the air with planes and try to figure out how do planes fly. 

       Aeroplanes, don't you feel fascinated to see huge machines made of metal and gears, soaring up above the world so high. I'm sure you do but , what seems like a reality today was no less than a distant dream a few centuries ago .

History :

     Before 1000s of years people have looked up at the sky and imagined, "what it would be like to fly". They tried various measures to beat gravity but, unfortunately failed again and again but..

        Two brothers named Orville and Wilbur Wright took this challenge of making humans fly and on December 17,1903. They created history by successfully executing the first control flight for a heavier than a flying machine. 

  

 Orville and Wilbur Wright

     This famous flight lasted just 12 seconds but since then many changes have been made to these flying objects and today with its help we can travel for hours across the world

How does aeroplane fly :

      but the vital question is, 

      "How can these machines with tons of weight fly so smoothly in the sky ?"

      Well, the answer to this mind-boggling question lies in the air,

       "Yes",the Air is a physical substance that has weight it consists of molecules.That are constantly moving around and create air pressure which plays a crucial role in making something fly. 

     Let's try to understand it ,with the help of a kite. You see when a kite is lying on a surface like a table. 

      The air pressure above  is very high as compared to the air pressure below it, where it's pretty low because of this high pressure from above the object continues to stay on the ground but ...

      When air blows below the kite, the air pressure underneath becomes higher than the pressure above it as a result the air generates a force called "lift" .  

     The object rises high in the air and this same force of lift is used while designing the airplane wings. Aeroplane wings are shaped to make air move faster on top of the wing . 

      When air moves faster the pressure of the air decreases.So, the pressure on 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 but ,this level of force isn't enough to elevate the aeroplane high above the surface. 

      So, to generate an extra lift the angle of the wings is tilted in a way that the air under it is deflected downwards to the surface and with the help of the coanda effect the air above the wings is guided downwards as well.

   

Forces of aeroplane

    So, now since the air is slowed and deflected down it generates enough force to lift the wings up and backward. 

     Wait a minute , on planes supposed to travel forward and that's where the role of an engine comes. In these powerful engines generate a force of thrust stronger than the force of drag created by the air pressure hitting the plane as a result the airplane moves forward. 

       When the air pressure increases below the wings ,the plane lifts in the air and we can enjoy our flight save your time.

 

Antonov An-225 Mriya

Fact :

    Did you know "Antonov An-225 Mriya" is the biggest aircraft in the world . Its length is 84 meters long while its wingspan is 88.4 meters long. Hope you learnt something new today. See you in a new post. 

                      Thank you!
