Because it is a drone, there is no need to consider the feelings of passengers, under the traction of a strong superconducting motor, the black Apollo drone climbs at an angle of more than 70 degrees, straight into the blue sky, which makes Wang Yinan's blood run high.

"When can I take such a passenger plane, although the comfort is almost good, but the speed of take-off and climbing, it is too exciting", Wang Yinan thought to himself, completely forgetting his fear of flying.

Apollo's cruising altitude is more than 20,000 meters, obviously it is not visible on the ground to see its test flight status, after watching the black dot in the sky slowly disappear, Chief Yang and the director of the 116 Institute and Wang Yinan came to the control center located in the tower together, there is already an early version of the Apollo UAV at high altitude, after replacing the microwave relay equipment with a camera, it will monitor the sky and broadcast the test flight process of the new model Apollo.

The scenery soaring above the clouds is still very beautiful, in fact, Wang Yinan likes the blue and pure sky very much, and blue is also his favorite, the only problem is, don't bump.

On a calm and sunny day, flying freely over the clouds is a great experience, well, as long as you don't have a strong convective weather or anything like that.

On the big screen of the tower, Wang Yinan saw such a beautiful picture, the flight altitude of the drone equipped with the camera was higher than the test flight altitude expected by Apollo.

Then a black dot appeared in the lens, the black dot approached rapidly, becoming larger and larger, and it could be seen from a distance, it was the shape of an airplane, and after the distant black object was no longer approaching, the camera lens began to zoom in, and sure enough, it was the Apollo drone with fat wings that had just taken off from the airport.

After reaching a predetermined altitude, the Apollo prototype no longer climbs and begins to hover around a virtual anchor point, with the fuselage slightly tilted to match the angle of the solar panels inside the wings to ensure maximum solar energy utilization at all times.

From a distance, a huge blackbird, circling around a virtual point in the sky, I don't know if it's an illusion, the huge wings seem to have a slight fan, such a scene is full of the texture of heavy metal technology, which makes people intoxicated.

Imagine that in the entire land of China, every few hundred kilometers square, there will be such a drone hovering in the sky, providing high-bandwidth network access for the base station on the ground and even every mobile phone, Wang Yinan couldn't help but get excited,

"Let's take a look at the pulsating production line you are building, the demand for this kind of drone is very large, when we can have enough drones to form a nationwide network, it's up to you," Wang Yinan said to Chief Master Yang.

Leaving the tower, Wang Yinan and Zhou Hui got on the battery car inside the 116 institute, and walked around the huge factory, "Aren't we taking a detour", Zhou Hui was a little dizzy, as if he would go south and north, why not go in a straight line.

Wang Yinan patted Zhou Hui and secretly said in her ear, "That's not because of you."

"What does going around in circles have to do with me?" , Zhou Hui was very puzzled, "Professor Wang, you can't bully me because I don't read much."

"Of course it has a relationship, Apollo is our company's project, and it is also a half-civilian project, so it doesn't matter if you take a look, you see that the huge yellow factory building over there is not", Wang Yinan pointed to a tall factory building in the distance that looked quite new and said, "If I guess correctly, it should be the production workshop of stealth fighters, if I am alone, it will definitely not matter, my brother's secret level is enough, there is no way to take you, we have to go around."

It seems to make sense, but Zhou Hui quit, "You mean to say that I'm just a drag oil bottle, a burden, right, I wouldn't have come with you if I knew it",

"How can you be a burden, I've seen enough of those things and don't want to read them", Wang Yinan said busily,

"Even if they invite me to see it, it's not unusual."

After going around the factory for a while, Wang Yinan easily calmed Zhou Hui, the electric car was parked at the door of a workshop that was a little old, Chief Teacher Yang and the director had been waiting there for a long time, they didn't have to make a detour, of course they ran fast.

Watching Wang Yinan and Zhou Hui walk down, Chief Master Yang introduced to them, "This was originally the pulsating workshop of the Thunder Dragon, and later the production line of the Thunder Dragon was handed over to Pakistan Railway, and this plant was empty, just the size of our Apollo is about the same as the Thunder Dragon, and it can be used as the pulsating production line of Apollo with a little modification, which is also the most labor-saving and economical way."

"It's good for you to weigh this yourself, anyway, as a partner, we hope that the production speed is as fast as possible, and the lower the cost, of course, the better," Wang Yinan said.

"You profiteer, the profits of this drone are already very high, and you want us to keep costs down as much as possible, you look at your capitalist face, where do you look like a Nobel Prize-winning scientist",

"Scientists also have to eat, only scientists with free wealth can use their wisdom to make greater contributions to mankind, right?" said Wang Yinan modestly at all.

"You are the first one to say that making money is so fresh and refined", Chief Master Yang gave Wang Yinan a thumbs up,

"I have to say that the thickness of your skin is still beyond my imagination."

The group walked into this huge workshop, where a large number of workers were busy, the workshop was about two stories high, the size of a standard football field, and when they entered through the gate, they could vaguely see the rails on the ground and the hangers on the roof of the room circled inside, and then went out through another door.

"This is the production line of the future, and the frames of the fuselage and wings will be assembled from the starting point of this door, after being formed here at one time," said Chief Engineer Yang on the side.

"Install a superconducting motor here",

"The next place to install the battery, landing gear and tail",

"And inside the wings, install solar panels and, of course, additional battery modules",

"And finally, the landing gear, and microwave transpondering equipment",

"When all completed, it is expected to produce more than fifteen Apollo drones per month."

Wang Yinan still believes in Chief Yang's ability, this is the chief designer of the stealth fighter, and the entire Blue Star can at least rank in the top five ruthless roles.

After visiting the test flight and the future pulsating production line, Wang Yinan is also full of confidence in the development of next year, and it is estimated that the stratospheric wanderer will be able to complete the initial networking in the first half of the year, and the competitiveness of this pair will definitely be a killer level.

Seeing the meal, at the strong invitation of the director, Chief Yang and the director of the 116 Institute hosted a banquet for Wang Yinan and Zhou Hui in the small canteen in the institute, and then, the deputy mayor in charge of science and technology in Shudu didn't know where to get the news, and he also came over to eat.

It's hard to be warm, Wang Yinan had to drink some beer, he never dared to touch the liquor, anyway, every time he drank liquor, Wang Yinan's final fate must be unconscious.

In the middle of the staggering, Wang Yinan secretly sat next to Chief Yang, "There were too many people to ask just now, although it was probably said on the phone, but it was more practical to ask in person."

"How is the progress of our engine and new material research, I may have to borrow two people from you recently, I have some material research needs here, and I will arrange two capable people to help me get it when the time comes."

"The old design of the engine is still in the finalization test, and it is estimated that it will be on the machine in about half a year", said Chief Engineer Yang, "but now all the interest is focused on the new full-state engine, which is a new design that can supply oil and oxygen at three or three points in the combustion chamber."

"We named it an all-round high-efficiency engine, which means that it can operate efficiently no matter what altitude, what speed, and what atmospheric content."

"Compared with the previous thrust-to-weight ratio, the increase is not a star and a half, compared with this new model of engine, the F135 of the rice country is a scum",

"It's amazing just to think about it, at a low altitude with abundant oxygen, it can exceed the thrust-to-weight ratio of the F135, at a high altitude with thin air, it is more efficient than a ramjet engine, and in a suborbital with almost no oxygen, it surpasses the RD180 rocket engine of the woolly bear, what kind of demonic existence is this", Chief Master Yang said excitedly, almost dancing with his hands.

And Wang Yinan's thoughts have drifted into the distance, such a demonic engine is simply customized for my space program, coupled with high-temperature resistant artificial muscles, that is, deformable materials, it is possible to achieve maximum fuel utilization and aerodynamic efficiency under any conditions.

And by making full use of the aerodynamic shape itself to recycle the vehicle, the reusable engine and the aerospace vehicle itself are not a problem at all.

Thinking about it, Wang Yinan showed a mysterious smile on his face, I don't know if it's in space, hehehe, you know, what does that feel like?

Chief Master Yang was talking about the rise, and suddenly found that Wang Yinan had no voice, he patted Wang Yinan on the shoulder, "By the way, I asked you about the airport design institute you were looking for last time."

Wang Yinan wiped the saliva from the corner of his mouth and came back to his senses from outside the sky, "Ah, what do you say, is the charge expensive?"

"I heard that you are going to design the airport, people are generous, both units said that you can look at the design fee on the line, to ensure that Professor Wang is satisfied, if not satisfied, modify until you are satisfied", Chief Teacher Yang shook his head, "This is the original words of others",

"Your face is simply bigger than the sky".

"Okay, let them find Zhang Qi directly, I'm going to Europa soon, and it is estimated that it will take a while to come back", Wang Yinan said,

Chief Yang's eyes showed fascination, "Europa, Stockholm, that's a good place."

"By the way, why do you want someone from the materials lab?" ，

"Preparing to develop a new material that is thinner and more durable than the thinnest TT material available, do you think the TT made by doing so will be profitable?" , Wang Yinan said with a smile, seeing that Chief Master Yang's face was almost green, Wang Yinan hurriedly raised his hands, "Just kidding, just kidding",

"Didn't I design my new headquarters with Mr. Pei, I used a lot of new materials, which can be regarded as photovoltaic building integration, which can not only generate electricity, but also control light transmittance, I am worried that the existing materials may not meet our requirements, or the price is too high."

"We have such a good X laboratory, and there is no need to be a pity for theoretical guidance, rest assured, there are new materials developed out, and your benefits are indispensable, after all, it is our joint venture laboratory."

"You profiteer", to Wang Yinan, Chief Master Yang is no longer able to complain.
