How does a plane stay in the air?

There are four main forces that keep the plane in the air. These are carrying, weight, push and drag forces. The most important of these forces are the thrust force provided by the engine and the bearing force created by the blades.

The carrying force is generated by the wings of the plane designed in accordance with the Bernoulli principle. According to this principle, the pressure is high in the part where the air moves faster while the pressure is low in the part where the air moves slowly. Therefore, the upper part of the wing of the aircraft is designed to be more curved, and the lower part to be more flat. This special blade design causes air to flow faster and create lower pressure at the top, slow motion at the bottom and create higher pressure. This air flow also helps to create an upward carrying force on the aircraft wings and thus the aeration of the aircraft.

When the four forces acting on the plane balance each other, the plane moves at a constant speed in the air. In other words, while the aircraft moves in the air, the bearing force generated on the wings balances the weight force caused by the effect of gravity, while the thrust force provided by the engine balances the air resistance, that is, the drag force. As we know from Newton's laws of motion, when all forces acting on an object equalize each other, the object stays in balance and moves in the air at a constant speed.
