Why airplane wings can withstand high weight

Mainly rely on the principle of aerodynamics: aerodynamics is a branch of mechanics that studies the force characteristics of aircraft or other objects in relative motion with air or other gases, the flow laws of gases and the accompanying physical and chemical changes. It is a discipline that has grown up on the basis of fluid mechanics with the development of the aviation industry and jet propulsion technology.

In low-velocity aerodynamics, the density of the medium varies so little that it can be regarded as constant, and for subsonic flow, the viscous potential flow obeys a nonlinear elliptical partial differential equation.

To put it simply, according to Bernoulli's theorem, the airflow passes through the upper surface, and the airflow is squeezed to accelerate and the pressure decreases, while when the airflow flows through the lower surface, the flow speed is slow and the pressure is high, so this pressure difference forms an upward lift, and when this lift is greater than the weight of the aircraft, the plane flies.

Why can a thin wing withstand the weight of hundreds of tons of aircraft? I can't help but sigh after reading it.

1. The wings are made of carbon fiber composite material, which is very strong, basically can withstand an overload of up to 3 g, and it is no problem to bend to a certain extent, so basically the wing is not dangerous when taking the plane.

2. Carbon fiber composite materials.

It has a high specific strength.

and specific stiffness, as well as mechanical properties.

It can be designed and other advantages, and is an ideal structural material for large civil aircraft.

3. At the same time, such a strong material is less dense than ordinary materials, which greatly reduces the weight of the aircraft. At the same time, there is also a wingtip at the very end of the wing, which is called a winglet.

4. During the flight. The high-pressure zone airflow on the underside of the wing bypasses the wingtip at the end of the wing to flow to the upfoil surface, creating a strong vortex current.

5. On the wingtips of the aircraft, add a small wing. The winglets block the airflow under the wing and flow to the top of the wing, destroying the formation of air vortices and solving this problem perfectly. In this way, the safety of the wing is well protected.

The maximum take-off mass of an aircraft is determined by the engines of the aircraft, and currently the maximum take-off mass of the largest aircraft in the world is 640 tons.

The maximum take-off mass of an aircraft is the maximum weight that an aircraft can tolerate during take-off due to design or operational limitations. The maximum take-off weight is one of the three design weight limits for the aircraft, the other two being the maximum zero fuel weight and the maximum landing weight. The total weight of the aircraft is calculated before the flight.

The pilot calculates the required take-off speed of the aircraft based on the gross weight and ensures that the total weight is below the maximum take-off weight.

The principle of the take-off of an airplane

The aircraft must be able to generate a lift force greater than the gravitational force of the aircraft itself during take-off in order to lift the aircraft off the ground. Since the aircraft can only produce a limited lift, the total weight of the aircraft itself must be limited to ensure that it can take off from the ground normally.

In practical applications, the maximum take-off weight is also limited by other factors, such as runway length, atmospheric temperature, take-off plane pressure altitude and obstacle crossing ability. When determining the maximum approved take-off weight of a civil aircraft, it is necessary to meet certain airworthiness standards, which are generally measured under the international standard atmospheric conditions stipulated by the International Civil Aviation Organization.

The internal structure is very powerful, because the most important thing is the wings on both sides, the quality of GE is directly related to whether the aircraft can take off, in order to achieve balance in the high altitude, first need to reach a certain weight.

This is because the wing of the aircraft is an inverted triangle shape to a certain extent, which can support a considerable amount of weight and is very strong, which shows how much care we put into making the aircraft.

Its internal structure is very complex, and the materials used are very hard, and the structure is also designed to be able to withstand compression, which is very powerful.

Aircraft engines weigh so much, why can the wings of an aircraft withstand it?
