On earth, there are two key technologies in the development of Aerospace Technology: one is supercomputer, the other is super wind tunnel.
In other countries, supercomputers are out of the question. With the tide leading the current level of science and technology, we can''t expect to produce supercomputers within 50 years.
To develop the aviation industry, Renault can only have a dozen ideas.
There are many kinds of wind tunnels, mainly divided into low-speed wind tunnel (0-0.4ma), subsonic wind tunnel (0.4-0.8ma), transonic wind tunnel (0.8-1.2ma), supersonic wind tunnel (1.2-5ma), and hypersonic wind tunnel (more than 5mA).
Supersonic wind tunnel is suitable for supersonic fighters, but Renault does not need it for the time being. Low speed wind tunnel is mainly used for vehicle test to optimize vehicle shape, reduce wind resistance and fuel consumption.
For example, many automobile manufacturers on earth have their own wind tunnel laboratories.
The subsonic wind tunnel is urgently needed by the sea tide.
But it''s not as easy to build as it''s supposed to be.
In fact, the principle of subsonic wind tunnel is very simple. To put it bluntly, a large fan is inserted into a large closed pipe, and the fan rotates to drive the air flow to circulate in the pipe at high speed.
So the question is, how fast should the fan speed be in order to blow out the air flow with the speed of 0.8ma (270ms)? How big is the blade diameter to ensure enough air volume?
How to design the blade shape and what kind of material should be selected to ensure that it will not be damaged in the process of high-speed rotation, or even fall off from the shaft and become a terrible murder weapon?
How to arrange the structure of the wind tunnel, that is, the large pipe, so that there will be no turbulence? In order to avoid too high air temperature, the wind tunnel has to install cooling device. Where is more reasonable to install this device?
No one can answer the above questions, including Renault.
For this reason, a group of Rune magicians said one after another: Lord, the wind tunnel you imagined is absolutely a wonderful and great idea. However, it''s too difficult to make this thing. We fools can''t make it for a while. Please give us more time to find out.
Then, a less wasteful magician, Peggy, offers a simple and crude idea.
That''s - al.
To be precise, put Al in the pipe, and the wind tunnel is done.
At the beginning of hearing this plan, Renault immediately had a strong impulse to "put this Mr. Peggy into the pipe".
But then he thought about it carefully, and suddenly realized that it was not nonsense. This plan was extremely feasible.
So Mr. Page became the director of the wind tunnel laboratory.
………………
Odin Island, wind tunnel laboratory.
"Mr. aer, please hurry up..."
Peggy stares at the magic anemometer and shouts.
……
Magic anemometer is a kind of precision instrument specially used to measure air flow velocity. Its core principle is similar to that of anemometers on earth. They all use "heat exchange theory", but the implementation method is different.
Of course, in the eyes of the magicians, it is also one of the innumerable wonderful inventions of the Lord.
The working principle of magic energy anemometer is as follows:
a metal probe is placed in the measured airflow, and a micro thermal magic heater is used to continuously transfer heat to the probe. When the airflow flows through the probe surface, part of the heat will be taken away.
That is to say, heat loss occurs.
The other end of the probe is connected with a thermal magic conversion device, which can convert the recovered heat into "thermal magic energy". Due to heat loss, the recovered thermal magic energy must be different from the input.
Finally, by using "Seth induction", this part of the difference is reflected in the crystal column reader. By comparing the scale, the specific value of wind speed can be obtained intuitively.
has always been ready to accept either course or phrase. It is only a quick word, a quick word or a quick word. It is a simple and full description of woodlouse.
The people of other countries have never thought about and even have no ability to establish a "quantitative standard" system.
It''s not surprising that people are obsessed with the power of nature.
Since Renault''s arrival, this situation began to be reversed. He led a group of magic mechanics to work quickly, and finally the first set of quantitative standards in history was born.
It''s a significant thing, though it''s destined to be unknown.
In terms of magic power technology, the reason why Haichao archipelago is far ahead of the rest of the world is not only the well-known powerful weapons such as "magic iron chariot", "Rose chariot" and "empty Knight", but also the unknown technology such as "magic power anemometer".
Renault insists that the latter is far more important than the former, because the latter is the foundation of the magic technology system and the cornerstone of the science and technology building. Without them, the rose chariot and the empty Knight are just castles in the air.……
After hearing Peggy''s urging sound, Al clenched his teeth and tried to activate the magic power in his body. More cyclones emerged out of thin air and set off a storm in the wide wind tunnel.
"Hoo Hoo Hoo Hoo... "
The extremely violent whistling made the transparent glass panel embedded in the pipe vibrate slightly, which made Peggy step back.
Al''s pet, black tiger "grut", is lying on the concrete floor, covering his furry ears with two claws tightly. It is obvious that the wind makes him feel uncomfortable.
Ten meters in front of the boy, a silver kite biplane was fixed on several metal pillars. High speed air swept around the silver kite and rushed to the distant air outlet.
Compared with Al''s previous test flight of the silver kite, the shape of the silver kite is smoother and the line curve is more beautiful.
One of the most eye-catching, but also the biggest change to the appearance, is a pair of wings.
The original wing was just two long strip-shaped metal plates on the fuselage, straight out to both sides, but now, the new wing has a bit of "swept wing" flavor, with both ends extending backward at an angle of about 150 degrees.
In this wind tunnel, Al plays the role of "humanoid fan".
With the extraordinary power of the wind system, we can easily create strong wind with speed within the speed of sound, and perfectly simulate the airflow of the real world, which can fully meet all the tests in the subsonic speed range.
After being abducted to Haichao archipelago by someone with delicious food, this silly young man lived a life of odd jobs and was "squeezed" by all kinds of people.
So far, teenagers have three jobs.
The first is a bird trainer. All the birds in the territory are al''s "little brothers".
The second is the test pilot. The development of silver kite, a metal biplane, is progressing so fast that the young people have made great contributions.
The third part is playing the humanoid fan in the wind tunnel, which is also the most difficult work that teenagers have ever done. To create such a fast strong wind, it costs a lot of magic power.
Peggy glanced at the crystal column reader of the magic anemometer, and saw that the red sensing smoke floated back and forth between the readings of 245-250m seconds. He quickly cried out:
"Mr. Aerge, that''s the speed. Please keep it for 30 seconds."
The young man closed his eyes and maintained a constant magic power output. At the same time, he focused on perceiving the fluid changes near the silver kite.
Peggy took out a pocket watch, followed the pointer for 30 seconds, and then called out again:
"you can stop, Mr. Aerge!"
Al took a breath, stopped the magic power output, and the wind in the wind tunnel began to weaken instantly.
Five minutes later, when the air flow in the wind tunnel completely subsided, the door was opened, and a group of magicians led by Seth swarmed in, surrounded the silver kite and al.
"Mr. Ayers, what are the defects of this silver kite''s aerodynamic shape?" Seth asked eagerly.
Al took out a marker pen, pushed his feet gently, floated over the silver kite, quickly drew a red circle at the end of the wing, and said:
"Mr. Seth, there is obvious swirling turbulence in this part, which will reduce the flight speed. I suggest adjusting the shape of the wing tip to make it slightly up..."
Then the boy floated to the fuselage, waved his right hand and drew four red circles.
"And the aerodynamic drag here is too large I suggest Here I think the shape needs to continue to be optimized... "
This is just another way to use the wind system, and it is also an extremely important way to use it.
When doing wind tunnel test on earth, it is a very troublesome thing to observe the flow field, either by oil flow display method, or by silk line display method, or by means of tracer particles, light and so on.
Either way, the observation results are not necessarily accurate, and there is a deviation between the actual situation.
Let the earth people headache, for Al, but easy.
The air flow is invisible and colorless, and no one can see or feel it. But in Al''s spiritual perception, every tiny disturbance is like a louse under a magnifying glass. It can''t hide his perception.
It must be admitted that in this respect, extraordinary power is much better than earth technology.
Finally, Al made a conclusion:
"if these 16 defects are eliminated, I estimate that the maximum flight speed of silver kite can be increased by 8%..."
"Really?" Seth''s face was instantly surprised.
Al nodded, rushed out of the wind tunnel and called to a pretty girl in maid''s clothes:
"sister Annabel!"
With a sweet smile, the maid quickly opened a metal box full of ice, took out a small bucket of ice cream from it and put it on the tablecloth.
"Young master, your dessert..."
According to convention, since al''s promotion, the boy has received a special "benefit" from the administrative department - a high-quality maid, that is, Miss Annabel.All the other elites in the territory regard the maids as "close maids". They serve them day and night.
Except for Reiter and al.
The former is brainless and takes the maid as a servant, while the latter is childish and treats the maid as a sister.
Al cheered at the ice cream on the table. He sat at the wooden table and waited for Annabel to tie her napkin. He immediately dug a large scoop of ice cream with a silver spoon and stuffed it into his mouth with a smile.
This is the most anticipated "afternoon tea" time for teenagers.
The price of ice cream is very low for most people who want to buy only 50 ice cream per month.
As a real eater, Al does not hesitate to spend most of his income on "eating". This guy has to eat 15 jinnals every month when he only eats ice cream, which is equivalent to a suite on Odin island. It can be called extravagance.
Gerut, the boy''s pet, was walking around him affectionately, rubbing his hairy head against the boy''s calf, making a "Wuwu" sound in his mouth, and looking up at the ice cream greedily from time to time.
"Gulu..."
Smelling the sweet smell of the air, Annabel couldn''t help swallowing.
Al''s ears moved, and suddenly he dug out a large scoop of ice cream and poked it into Annabel''s mouth with a "Shua". He cried enthusiastically:
"sister Annabel, have a taste, too..."
Annabel was stunned for a moment. She looked around carefully for a moment and found that the magician''s attention was on the silver kite. Then she straightened out her chest, opened her red and tender lips, stretched out her lilac tongue and licked the ice cream. A pair of beautiful peach blossom eyes narrowed slightly.
The maid, like a kitten, licked one mouthful after another. Her face was full of joy. Her small white nose was open and close, and with the action of licking, she looked very charming.
It''s a pity that Annabel''s performance is full of temptation. It''s just a shot in the dark.
Al saw that she licked endlessly. He was a little impatient. The boy simply put the silver spoon into her mouth.
Annabel was surprised, and the ice cream almost came out of her nose.
AI Er grinned at her, then quickly took out a silver spoon from her mouth, dug another spoon of ice cream and put it into her mouth, with a beautiful face.
Annabel looked at her young master in tears, and her eyes were full of resentment.
Young master, young master When will you be enlightened
………………
Chaka town.
In the heavily guarded air Knight base, 22 large paper airplanes are parked neatly on the runway.
More than ten magic delta wings that had been damaged before, Renault personally repaired them in just half an hour, even better than when they just left the factory.
In the process of repair, he used his magic skills [ideation power] and [reverse heat conduction] to correct the design and manufacturing defects of the large paper aircraft.
For example, some parts of the joint exist false welding, the weld strength is insufficient, and it may lead to fracture when subjected to severe impact.
However, after Renault''s skillful efforts, the steel tubes that make up the framework of the delta wing become a whole without any gap between them, which is no different from "integral forming".
Renault took a deep breath and waved to a wooden box. The box broke apart with a bang. Six or seven blue and black shadows shot at him.
"Keng, Keng Keng... "
After a few metal collisions, the Shura armor was finished.
Through the crystal panel of Shura helmets, Renault glanced at the 21 players, including Gollum and others. Looking at the firm eyes of the people, he nodded with satisfaction and said in a voice:
"ready to go!"
Then Renault marched to the front of a large paper plane, and the others immediately ran to their respective cars.
He just straddled on the very simple seat, and before he started the jet engine, the whole delta wing suddenly moved slightly, left the ground quietly, and quickly rose into the sky.
Ray, somebody drives, no, flies, no power!
Because he has his own motivation.
Even though the weight of Shura armor is far more than that of the delta wing, it is extremely flexible. It seems that the sky has turned into the ocean, and the delta wing has become a swimming fish.
The team members looked at the LORD with admiration, started the engine one after another, and drove the large paper airplane to slide slowly on the runway.
A minute later, under Renault''s leadership, 22 delta wings grew into a long line and quickly fell into the sky.
Target, Fort Dante!
