Originally, although the refining hall was heavy, there was still some research on runes, so the general rune array could still be dealt with.

But really playing the rune array can't compare to the spirit rune hall, after all, it is a specialization in the art industry. Similarly, the Spirit Rune Hall's tools are definitely far inferior to the Refining Hall, and some of them are not even the same.

In the refining hall, Zhang Songxi looked at the "Flying Board No. 2" produced by Tiangongtang and shook his head, many elders of the Zhang family were discussing fiercely.

Now they are divided into two factions, one group advocates asking a master to crack it, and then fight with Tiangong Academy to the end, and the other group advocates not following the trend and researching new products to compare Tiangong Academy......

For those discussions, Zhang Songxi, who was humble on his face and shrewd in his heart, was too lazy to participate.

When neither of the two factions was convinced, and it seemed that neither approach was good, someone finally remembered to ask Zhang Songxi's opinion.

Zhang Songxi took a sip, and he is not in a hurry to express any opinions now, the big family is a big force and a big backer, but there are also advantages and disadvantages, and the family is big.

Although Zhang Songxi has a lot of weight in the family, he doesn't like to say things that are not nutritious.

When others quarrel fiercely, he has always been too lazy to speak, which is a habit that Zhang Songxi has developed for a long time in the family struggle.

He thinks it's a good habit.

When others asked a second time, he finally opened his mouth to express his opinion: "It's too expensive to invite people, and you don't know those people in Tianjimen." The Tiangong Academy can make Flyboard No. 2, but if we make it, they will upgrade again? Wouldn't that be a waste of effort?"

Zhang Songxi expressed his opinion, and the think tanks of the Zhang family began to discuss again......

Many of them knew that what Zhang Songxi said was right, but they were unwilling to let the Tiangong Academy be arrogant and do nothing.

Just when the Zhang family was discussing countermeasures, Han Xiao launched another magic weapon-wing.

Originally, Han Xiao was going to research a pair of double magic weapon wings for his war beasts.

But the magic weapon wings were not studied, first the flying board was made, and then, now the sword went sideways, and then the wings were made!

Airplanes are the wings, but they are not the wings of birds, but the wings of airplanes.

Han Xiao found that making a pair of wings was much better than making wings.

The structure of the wing is simple, however, it also has the ability to fly, and the applicability is still very strong - after testing, Han Xiao found that the magic weapon wing can be used by both humans and war beasts.

So, following the Flyboard No. 2, Tiangongyuan launched the magic wing.

Magic wings, of course, are not rigid.

The magic wing designed by Han Xiao is a foldable wing, which is very delicate.

As soon as it was mass-produced, there was immediately a small spirit gathering rune array, as well as the function of adding spirit stones, and after it was launched, it was widely acclaimed.

Moreover, many people have discovered that after the Tiangong Academy launched the combination of flyboard and wings, a new combat mode became popular in the Spirit Sword Sect - that is, the flyboard and wing flight, and then, the mode of Edgeworth fighting.

The flyboard and wings can completely replace the flying sword, and the double flight insurance liberates the flying sword.

Moreover, the wings are really convenient, and you can feel the feeling of flying like a bird.

On Earth, the wing is one of the important components of the aircraft, which is installed on the fuselage.

Its main function is to generate lift, but it can also be used to place ammunition compartments and fuel tanks inside the wings, and to store the landing gear in flight.

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.

The role of the wing is to generate lift to support the aircraft in the air.

It also plays a certain stabilizing and manipulative role. There are various plane shapes of wings, and the commonly used ones are rectangular wings, trapezoidal wings, swept wings, delta wings, double delta wings, arrow-shaped wings, edge strip wings, etc. Modern aircraft are generally monoplanes, but there have also been historical bands of biplanes (two sets of wings overlapping top and bottom), triplanes, and multiplanes.

According to the connection between the wing and the fuselage of the monoplane, it can be divided into lower wing, middle wing, upper wing and umbrella upper wing (that is, the wing is above the fuselage, and the wing and fuselage are connected together by a set of struts).

The principle of the force generated by the wing can be explained by Newton's third law and Bernoulli's law. When the airflow parallel to the chord direction (here it is considered non-compressible) flows through the wing, the flow tube section becomes smaller due to the obstruction of the wing, resulting in an increase in the velocity of the air on both the upper and lower surfaces of the wing.

However, since the curvature of the upper surface of the wing is greater than the curvature of the lower surface, according to Bernoulli's law, it can be seen that the flow velocity of the upper surface air flow is generally higher than that of the lower surface, that is, the static pressure of the air flow acting on the upper surface of the wing is less than the static pressure acting on the lower surface as a whole.

Due to the difference in pressure between the upper and lower surfaces, the wing is finally subjected to an upward resultant force, that is, lift.

Of course, as the angle of attack of the wing relative to the airflow changes, the air flow field around the airfoil will also change significantly. When the angle of attack of the wing increases, the airflow is washed down due to the obstruction of the airfoil on the airflow, which makes the airflow station near the leading edge move down relative to the position of the leading edge, resulting in a more obvious lift effect.

When the angle of attack of the wing decreases or even becomes negative, the effect of the airfoil curvature will be weakened, that is, the lift will decrease until a negative lift force is generated.

Aircraft are not only bionics, but also aerodynamics derived from the study of bird flight.

The bird uses its wings to fan to generate vortex air pressure, and the air pressure is lifted downward, and the air pressure is backward and downward, and it gains forward momentum......

The flight mode of birds is to have lift by flapping the wings, and at the same time adjust the flapping wing and tail attitude to adjust the flight direction (note that the general flapping frequency of birds is about 1000 per minute)

Modern airplanes fly in such a way that upward lift is obtained at forward speed through the aerodynamic construction of the wings.

The reason why modern technology has not been able to build a machine that can support a bird-like flight system (flapping wing) is that the required flapping frequency is too high, and the output of modern engines (even jets) is required to be a few thousandth, so the flapping wing flight method is abandoned.

As an ordinary aircraft, because its own power system is sufficient, and the addition of the flapping wing system will also cause the stability of the aircraft to be greatly reduced, the aircraft generally does not use the flapping wing system......

Han Xiao had studied it before......

Now, even if you want to make magic wings, it's a very difficult thing to do, because if the wings are not done well, it will really affect the stability of flight.

If you make a wing, it will be even better
