How the lift force occurs on airplanes?

Flying is basically a heavy cistern from the air, able to be held at a certain altitude in the air and able to move in the air. Movement in air is called flight. An object in the air is pushed upwards with a force equal to the weight of the air as the volume it covers. If this force is less than the cismin weight, the object will not move. If the force is equal to the weight, the object remains in the state it is in. If the force is greater than the weight, the object rises. This is called the levitation force which gives rise. 

So, how is the lift force provided?

Many aircraft provide the lift force required for them in different shapes. For example, the balloon obtains the required lifting force by heating the air filled in it or by filling it with light gas from the air. The zeppelins are almost identical to the flying balloons. The filling force is obtained by filling with hydrogen which is a lighter gas than air. Because the hydrogen gas used is a flammable gas, the zeppelin was abandoned years ago. The Hindenburg Disaster, which was a big influence at the beginning of modern aviation, has shown to human beings how dangerous the zeppelins actually are.The Hinderbug Catastrophe in Brief, LZ 129 Hindenburg, the largest zeppeline in the world, was built on the May 6, 1937, at the Lakehurst Naval Air Station in New Jersey, with the influence of hydrogen tanks, 61 crew) is a disaster resulting in the loss of life.

When we return to the main topic, we will classify the main bodies moving in the air as fixed wings (planes, gliders, etc.) and rotating wings (helicopters). Fixed-wing aircrafts provide lifting force, not surprisingly, with engines, but wings, with a more scientific expression, the profile of the wings. The mission of the engine on the aircraft is to provide the thrust needed to accelerate the aircraft. With the acceleration that the engine creates, the plane starts to accelerate. The accelerating aircraft starts to take off due to the special aerodynamic structure (profile) of the wings and the lifting force generated by the wing. 

The lifting force of the wings depends on the foundation of the formation of the Bernoulli Principle.What is the Bernoulli Principle?Air is a fluid. According to Bernoulli, fluids reach the end of each part of cismin in the same time as they pass an object. Here, the fluid fixed object may be in motion. And again according to the Bernoulli Principle, as the velocity of the fluids increases, the pressure drops. 

According to Bernoulli, the half-drop of the aircraft wing rapidly passes through the air, while the air molecules that go a long way from the top of the wing, and the air molecules that come from the bottom, reach the back of the wing. As they have reached the same point, those who come from the long way are fast. Because they came fastDue to the pressure drop above. The high pressure underneath the aircraft’s wing pushes the aircraft up, creating the lifting force that the plane needs to lift off the ground. We can explain the airing of the aircraft as basic and simple in this way.

There are 4 main forces on the plane. These forces are;

Thrust

It is the force that moves the aircraft forward in the air. If the pushing force of the aircraft is higher than the friction force, it will accelerate. If the push and friction forces are equal, the aircraft continues to fly at constant speed.

Friction (Drag)

It is the opposing force that takes place during the movement. The coefficient of friction increases in proportion to the squared angle.

Lifting (Lift)

    Gravitational forces. (Gravity)

Gravity pulling down the plane is strength. The aircraft acts as if the whole weight is at one point. This point is called the “Center of Gravity” Center of Gravity or simply CG.

Rotating Wings

Another main aircraft is a helicopter that is widely used in today’s arena and is a technology that develops day by day. Basically, the flying principles of helicopters and planes are essentially the same. The airplane is moved in the air so that it can obtain lift force on airplanes. The wing is a fixed structure connected to the aircraft body. But in helicopters the wings are not fixed, they are motion. In helicopters, rotary wings or propellers are used to obtain the carrying force. The propeller may come in two or more palpated lanes. The profile of the propeller palyne is the same as the profile of the aircraft wing. The helicopter motor provides the power needed to rotate the pallet. As pallets move in air, low pressure on their upper surfaces, high pressure on their lower surfaces. This difference in pressure brings the carrying capacity to the stage. The size of this transport force increases with the increase of pallet’s number of revolutions and attack angle. Otherwise, it decreases. When the carrying force is equal to the weight of the helicopter, the helicopter remains constant in the air. It rises when it is big. In the case of less, it will descend.
