Nowadays, air travel has become so common, and certainly many of us have been on an airplane. However, not everyone knows the principle of operation for the plane to take off and lift themselves off the ground.
Each commercial aircraft today weighs hundreds of tons, becoming a popular means of transport in the world. But many people still wonder how the plane took off after running for a while on the runway and how to keep balance in the air.
Take off thanks to aerodynamic lift
The jets are equipped with engines mounted in two wings. The air mixed with the burned fuel, the gas product then released will push the aircraft forward. When in motion, the aircraft is affected by four forces in different directions, including: drag of the air, gravity, engine thrust and lift force.
Of these, the aerodynamic lift is not well known to people. It is explained as follows. As the plane runs on the tarmac, the air flows around the wings of the plane creating the difference in pressure between the ground and the top of the wing.
The result of this process is to create the force to lift the plane from the ground up to the sky. The faster the movement speed, the greater this thrust until gravity is overcome, helping to raise the aircraft into the air.
To create aerodynamic lift, the wing profile must be asymmetrical across the main shaft and the upper surface boundary must be larger than the lower surface. It is the special design of the two blades that makes the airflow rate on the wing much larger than the airflow rate under the wing, creating a difference in the pressure above and below, thereby generating lift. This force is proportional to the square of the plane’s velocity and wing area.
But once it takes off, how does a plane balance this force with gravity?
The up or down tip of the plane determines whether the plane will fly up or down.
Flight process in the air
In addition to the main lift wing, the jet also has a horizontal tail (to create lift for the tail of the aircraft), a rear flap and a pitcher (which is a movable part behind the horizontal wing), and a pitcher (changeable to make the lift on both sides of the wing differ), the flaps and brakes dynamically.
Adjusting these wings and engine thrust will help the aircraft keep its balance in the air, as well as perform wing tilt, change direction to the left, right, fly up and down, change altitude when flying by …
