Hi Guys 😎
In this post, I will explain how to fly an airplane and how pilots can control an airplane with a simple introduction.
If we look at airplanes, we can realize that they are not made as a single solid piece. Because, it has many movable parts. The most interesting thing about its various parts is that they take on a unique shape in fluid mechanics. As, I'm an Aeronautical Engineer, I usually refer to it as "Aerofoil shape". By understanding the physics behind this simple shape we can fully understand Aeronautical Physics.
When the airfoil shape moves relative to the air it produces a lift force. Simply, lift force is the power to go up. This lift force helps to fly an aircraft. Larger air speeds also significantly increase the lift.
You can understand that, this airfoil shape seems to like simple curved shape. Interestingly, to make a successful flight, we should use this airfoil principle by controlling along the wing span. Although this airfoil shape is a simple curved shape, it is sufficient to produce a good downwash. Actually, there are two such airfoils. However, there are many more factors that go deeper than this. But I hope to explain this in a very simple way.
There are three ways to increase the lift of an aircraft. If we want to increase the downwash and increase the lift, we should use flaps and slats. If I explain about flaps and slats, the front part of the wing is slat and the back part of the wing is flap. Here I have attached an image to get an idea.
If we want to decrease and increase the lift force respectively, we can move this wing to up and down. Actually, we call it “Ailerons up and down”. Near the tail of the plane, there are two attachments. Those are the rudders and the elevators. To control the vertical force on the tail, we use elevators. And also, to control the horizontal force, we use the rudder.
Now this is the most interesting part of this post, it is the flying part of the flight. We usually known it as " takeoff ". To get the plane off the ground, all you have to do is increase the lift force using various tactics. But, the important part is that we make sure this force is greater than the gravitational pull. For a successful takeoff, we must apply all the three lift increase modes together. It is a mandatory role of a pilot. However, during takeoff, the aircraft operates at full power.
When the speed of the aircraft is high enough and the lift is increased according to flaps and slats, then the airplane is ready for takeoff by activating the elevators upwards.
As long as the pilot controls the power required by the aircraft engine, He can fly the plane to the destination. Although there are many more significant considerations here, I just wanted to give an idea of this process. I hope you were able to get an idea about this. So, I really appreciate your ideas in the comment section.
Thank you for your valuable time.
