Every aircraft will have one or two engines, and most of the time, the engines of the aircraft will be mounted under the wings.
There are drawbacks and advantages to such a design, but what is more worth exploring is whether the wing can really withstand the weight of the engines.
Why are the engines of the aircraft installed under the wings.
The engines of the aircraft are mounted in two positions, which are mounted on the wing and under the wing, while the engines mounted on the wing are both helicopters.
Engines and wings are interrelated, and there are many benefits to having an aircraft engine mounted on a wing, which is why the designers of the aircraft have laid it out in this way.
Airplanes generate a lot of drag during takeoff, landing, and flight, and the nose of the aircraft is where the flight resistance is the greatest.
In order to reduce the air resistance of the nose of the aircraft, the installation position of the engine is crucial.
Most of the structure of the aircraft is curved downward, and the position of the wings is the largest area of the aircraft, and in order to reduce the drag of the aircraft, the position of the engine is also moved downward, and finally it is installed under the wing.
At the beginning, the design of the aircraft was just a few wooden components, and they had a very simple structure, so that the engine was mounted directly on the wing, and the wing was used as a simple support, which was simple and easy to install, which was convenient for the production of the aircraft.
Moreover, such a structural form can also effectively reduce the weight of the entire aircraft, and also make the center of gravity of the aircraft sink and improve the stability of the aircraft.
The structure and design of the aircraft fuselage are simplified, the production cost is reduced, and the maintenance of the aircraft engine is more convenient.
The airplane creates an airflow during flight, and installing it under the wings can effectively separate the airflow and reduce the drag of the aircraft.
On the contrary, if the engine is mounted on the wing of the aircraft, the air will be unstable during the flight, and the aircraft will also shake, which is prone to the problem of aircraft stalling.
Will the wing be able to withstand the weight of the engine.
The engine is the power plant of the aircraft, and since it is installed on the wing, it must ensure that the wing can withstand the weight and tension of the engine.
With the continuous development of technology, the material of the aircraft is also constantly updated, in order to ensure that the wing can bear greater weight, so the designer of the aircraft has also adjusted the material of the wing, so that the force of the wing is more uniform, and the wing can withstand greater force.
For decades, the wing structure of the aircraft has been constantly updated, and the update of materials and the improvement of design have made the wing of the aircraft bear more force, and at the same time, it also makes the aircraft fly faster and faster in the air.
The wings of airplanes are generally made of metal materials such as aluminum alloy, and the material of the wings will also be adjusted according to the type of aircraft.
The wing of the aircraft has also undergone many years of development, and it was first installed on the wooden wing, because the wooden material is relatively primitive, its toughness and strength are relatively poor, and the durability of the aircraft is not high.
Later, it was mounted on steel wings, which were used in older aircraft.
However, with the development of the times, people's requirements for aircraft are getting higher and higher, in order to make the aircraft able to fly better, so people have begun to develop a variety of new materials, people have introduced composite materials into the wing of the aircraft, and the toughness and strength of the wing of the aircraft have also been significantly improved.
In addition, composite materials also have the characteristics of high temperature resistance and corrosion resistance, which can ensure the safety of aircraft in the air for a long period of time.
At the same time, the specific gravity of the composite material is also light, which can reduce the weight of the aircraft to a minimum, which provides great convenience for the flight of the aircraft.
The wing of the aircraft is composed of the upper wing and the lower wing respectively, and the force between the two wings is too large, which may cause a stall at any time, and the wing will be designed and modified in order to make the force between the two wings more even.
Over the years, the wing structure of an aircraft has been complex and constantly changing, and as technology continues to evolve, the wing of an aircraft will evolve into the future.
Each aircraft will have one or two engines, and the engines are evenly installed on the wings on both sides, which can make the force between the two wings more even, and can also make the aircraft more stable.
Although the weight of the engine is relatively large, the weight of the wings of the aircraft is much greater than the weight of the engine.
The wing of the aircraft must not only bear the weight of the aircraft, but also the lift, pull and drag generated by the aircraft during flight, so the weight of the engine is nothing to the wing of the aircraft.
In order to make the engine better connected to the wing, the aircraft designers will wear some bolts and nuts on the scaffolding of the engine to tightly attach it to the top of the wing, and some aircraft designers will install some beams inside the wing to bear the weight of the engine.
In addition, the crosshead can also install the engine more evenly without affecting the force on the wing.
The wing is generally composed of the upper wing and the lower wing, but for large passenger aircraft, the force between the two wings is very complex, and the designer of the aircraft will also install some rods and beams inside the wing to connect the upper wing and the lower wing, so that the force is distributed more evenly, and the safety of the aircraft in the flight process is ensured to the greatest extent.
The advantages of the engine under the wing.
During the flight of the aircraft, air currents will be generated under the wings, and these air currents are like a fan under the wings, which can accelerate the air, and finally the lift of the wings can also generate more lift, which is very helpful for the flight speed of the aircraft.
In addition to being the power plant of the aircraft, the engine of the aircraft also plays a considerable weight, which can also make the engine more stable and reduce the probability of the aircraft shaking during flight.
The engine is installed under the wing, which will not affect the lift generated by the wing during flight, nor will it put too much burden on the aircraft, making the aircraft lighter.
The engine is installed under the wing, not only can make the lift of the wing larger, but also can ensure that the force of the wing is uniform, some medium and long-range aircraft have a larger wingspan, if installed on the wing, the force of the wing will be concentrated in one place, so that the wing will be bent and deformed, and eventually affect the air flight of the aircraft.
Epilogue:
The engine of the aircraft is mounted on the wing, which has its own disadvantages and advantages, and the engine installed under the wing can reduce the air resistance of the nose, and can also reduce the center of gravity of the aircraft, which is more stable.
The weight of the engine is not large, the wing can withstand it, and the engine is mounted on the wing has many advantages, and reducing the drag of the aircraft will not have a negative impact on the aircraft's flight in the air.
