Flying
This summer I moved from Canada to Serbia. I flew here, and it was a lot of fun! I really like flying. The take off, the view in the air, the land of clouds, the landing. It's really very exiting, and interesting to learn about.
The Science of Flying
To get a plane into the air, you have to manage the science first. See, there's this thing called air pressure. Fast moving air has very low pressure, and slow or non-moving air has high pressure. To get the plane in the air you have to get the high pressure under the wing and the low pressure above. So the wing is shaped to make the air above it move faster than the air below it. How? They make the top of the wing curved and the bottom of the wing flat, forcing the air above to move faster in order to get to the edge of the wing at the same time as the air below, thus creating a difference in pressure and lifting the plane.
There are four principles in flying. What I just explained was lift. The other three are weight, thrust and drag. Weight is the opposite of lift, it's opponent. While the lift pushes you up, the weight pulls you down. if it weren't for weight, we'd all go shooting off into space the second we tried to fly!
Thrust is created by the motors of the plane. The turbines move as air rushes through them because the plane is moving, and they push the air to the back, all the while pushing the plane forward.
Drag, like weight vs. lift, is the opposite of thrust. Is drags the plane backward. The plane makers try to get the least drag as possible by making the plane aerodynamic. That means shaping the plane in a way similar to that the shape of a cone so that it cuts though the air, instead of pushing against it like it would if it were a box. But, in the midst of trying to prevent drag, its actually a good thing, because without it, like weight, we would go shooting off into who-knows-where!
So, that's the science of flying. I hope you learned something, if not, well, I tried!!!
