Why does an aircraft fly ?
Firstly welcome to my blog.
In our first post I would like to explain how an aircraft flies .
I always wondered how is possible that an aircraft , which weights tones can fly .
It is based on 3 physical laws , Venturi effect , straw effect ( I call it like this , but its real name is fluid static law ) and the third Newton law.
The Venturi effect says that If the speed increase , the pressure of the fluid decrease.
The straw effect it is based on the Pressure difference , results on a force in the way of the highest to the lowest pressure . You might wonder why I call it straw effect , have you ever stop up one part of a filled straw with your fingers ? As you can see , the liquid doesn't move , that's because the pressure of each part of the straw are the same , when we remove the finger , the liquid spills .
The third Newton's law , it is the action - reaction law , which means that if you hit the table , the table hits you back .
The engineers invented a system which all three effects work together , and it is the shape of the wings . There are different kinds of wings , but the most common are those which the bottom part is straight and the upper part is curved , which makes that the fluid is faster in the upper side than in the under side , resulting in an increase of pressure in the under part, and decrease in pressure on the upper part ( due to the Venturi effect ) , that's why a lift force is created ( straw effect ) , furthermore the air is stuck on the wing ending downwards creating an upwards force ( 3 Newton law ).
I wanted to explain the most important reasons , although there are more .
I hope you enjoy reading that post , see you soon !
