What are the wings of an airplane used for? Why was it designed like that?

The wings of an airplane are able to maintain balance and then provide the corresponding power. It is also a principle of bionics that it can make the aircraft fly, and at the same time, it can provide a very sufficient power with the help of external forces, and it can also keep the aircraft balanced.

The wings of the aircraft can control the speed of flight, as well as the direction of flight, because the air pressure above and below the wings is different during the flight of the aircraft, which can maintain the balance of the fuselage.

In order to maintain the balance of the aircraft, the air flow can be well divided, and the atmospheric pressure can be used to better allow the aircraft to take off.

The wings are designed to be suitable for flight and have a fixed "airfoil". From the leading edge of the wing to the trailing edge, the upper surface of the wing is convex and the lower surface is relatively flat. As the air flows through the wing, it is divided into updraft and downdraft by the wing and rejoins at the trailing edge of the wing and flows backwards.

Because the upper surface of the wing is designed with a protrusion, the airflow tube on the upper surface is relatively thin, so the speed is high and the pressure is low. On the other hand, the airflow ducts on the lower surface are thick and slow and the pressure is high, which creates a pressure difference between the upper and lower surfaces of the wing. (It can also be understood colloquially that the air flows over a long distance on the upper surface of the wing, but at the rear of the wing, it must meet the air flow on the lower surface, that is, the air flow on the upper and lower surfaces flows through the wing at the same time, so naturally the air flow on the upper surface has a high velocity and low pressure).

This pressure difference provides lift to the aircraft. Lift makes it possible for aircraft to fly through the air.

I think that the wings of an airplane are good for flying, it allows the airflow to move with each other, and the wings of the airplane and the other parts of the airplane work together to increase the speed of the airplane.

Aircraft'sThe main function of the wing is to increase lift or change the attitude of the aircraft.

The wing is the main component used in an airplane to generate lift. It is generally divided into two wings, left and right, and is arranged symmetrically on both sides of the fuselage. Some parts of the wing, mainly the leading and trailing edges, can be moved.

The pilot maneuvers these parts to change the shape of the wing and control the distribution of lift or drag in the wing to increase lift or change the attitude of the aircraft. The movable wing surfaces commonly used on the wing include various leading and trailing edge lifting devices, ailerons, spoilers, speed brakes, lifting ailerons, etc.

The inside of the wing is often used to place fuel. The main landing gear of the aircraft is also often fully or partially tucked within the wing, as the thickness of the wing allows. In addition, the engines of many aircraft are either fixed directly to the wings or suspended under the wings of the reserve aircraft.

The role of the wing is to generate lift to support the aircraft in the air. In addition to this, it also plays a certain stabilizing and manipulating role.

Partial composition of the wing

1. a spar. The spar consists of the web and lines of the beam. The spar is a simple force member, which mainly bears bending moments and shear forces, and it is the main longitudinal force part of the wing, which bears all or most of the bending moments of the wing. The spars are mostly fixed to the fuselage at the root.

2. Longitudinal wall. The edge of the longitudinal wall is much weaker than that of the spare. However, most of them are stronger than ordinary girders, and the connection between the longitudinal wall and the fuselage is regarded as hinged.

Longitudinal walls and webs are generally not able to withstand bending moments, but form a closed box with the skin to withstand the torques of the wings. The longitudinal wall also has the effect of enclosing the internal volume of the wing.

3. a stringer. The stringers are elements that are connected to the skin and the wing ribs. In modern wings, it generally participates in the overall force of the wing, bears part of the axial force caused by the bending moment of the wing, and is one of the important force elements in the longitudinal skeleton.

In addition to the above-mentioned load-bearing effects, the trusses and wing ribs together play a certain supporting role in the skin.

Because the distance traveled by the gas as it passes over the upper surface increases, and the gas on the upper and lower surfaces must flow through the gear wing at the same time, meeting behind the wing (otherwise there will be a vacuum), the gas velocity must increase.

An airplane is a heavier-than-air aircraft that flies through the atmosphere with a power plant with one or more engines that generates forward thrust or pull, and lift is generated by the fixed wings of the fuselage.

Composition:

Wings are typically made up of spars, stringers, stringers, ribs, and skins. The basic stressed members of a wing include a longitudinal (span) skeleton, a transverse (perpendicular to the spar direction along the direction of the airflow), and skin. The longitudinal skeleton has wing beams, longitudinal walls and stringers, and the transverse skeleton has ordinary wing ribs and reinforced wing ribs.

The spar consists of the web and lines of the beam. The spar is a simple force part, mainly bearing bending moment and shear force, it is the main longitudinal force part of the wing, bearing all or large part of the wing and part of the bending moment. Most of the spars are fixed to the body at the root.

<>WingsIt is one of the important parts of the aircraft and is installed on the fuselage. Its main function is to generate lift to support the aircraft in the air, but also play a certain role in stability and control, but also can be placed in the wing ammunition compartment and fuel tank, in flight can be stored landing gear. In addition, flaps to improve take-off and landing performance, ailerons for lateral maneuvering of aircraft are installed on the wings, and some are equipped with slats and other lifting devices on the leading edge of the wings.

WingsThe interior is often used to place fuel. The main landing gear of the aircraft is also often fully or partially tucked within the wing, as the thickness of the wing allows. In addition, the engines of many aircraft are either directly attached to the wings or suspended under the wings.

The tail of the aircraft is an important part that controls the pitch and deflection of the aircraft and is responsible for the smooth flight of the aircraft. The tail of the vertical direction mainly guarantees the flight direction of the aircraft; The horizontal tail is mainly used to ensure that the aircraft can safely rise and fall when flying. In addition to maneuvering the aircraft to deflect and lift correctly, the tail of the aircraft also plays a balancing role in the center of gravity of the aircraft and the lift of the wings.

The propellers mounted on the head of the aircraft rotate constantly, pulling the aircraft forward.
