In the middle of the room, there was a large metal plate on the test bench, the color of the metal plate was black, as if it had been smoked, and it didn't look good.

Of course, we don't care about the appearance of the experiment, the key is to look good or not, the black metal plate is like the root system of a plant, growing a long cluster of black fibers.

Wires were attached to the root and top of the fibers, and the weights used on the balance were hung on the top of the fibers, and as the white coat monk with glasses opened and closed, the fibers began to shrink, and the weights were lifted up at once.

"Great", the two white coats let out a burst of cheers, and Wang Yinan grabbed a scientific research dog casually, "How much weight does it weigh now?" How many of these electrically deformable fibers are used? ”，

This scientific research dog is still very confidential, he hesitated, did not immediately answer the stranger's question, He Zhenbo walked over, "Jiang Yu",

"This is our big boss, Professor Wang of Imperial Capital University, you can say it quickly",

Jiang Yu was taken aback, "Yes, we used five fibers, and now the weight is five kilograms."

Looking carefully at the very fine fibers on the metal plate, Wang Yinan has a spectrum in his heart, such a little fiber can drive a load of five kilograms, even if the existing materials are used, it is no problem, more driving force is needed, and it is a big deal to continue to increase the number of fibers.

"What about the consistency of the material?" The so-called consistency is whether the shrinkage characteristics of the material are consistent when the same voltage or current is applied, for example, if tested 10,000 times or more, is it the same length of shrinkage.

Only if the consistency is very good, can you write control code for this material, which is used to drive the operation of the machine, if the length of the contraction is different every time you turn on the power, even the gods can't use this material to drive the machine, unless it is an exhaust machine.

"At present, the number of tests is not enough, but from the results of our thousands of tests, the consistency is very good, and no signs of attenuation have been observed so far," He Zhenbo replied on the side.

"It's great, go back and prepare as many materials as possible and send them to the imperial capital," Wang Yinan said.

"Also, it's better not to publish the paper yet", Wang Yinan said to Chief Master Yang, "This thing may still be a big killer."

Chief Master Yang nodded and agreed, after visiting the laboratory, with such a big windfall, Wang Yinan was in a good mood,

"How's our new turbofan engine?" , Wang Yinan asked,

"The thrust-to-weight ratio has exceeded 12, the level of the whole Blue Star is unique, and it is currently undergoing large-scale finalization tests", said Chief Yang is full of pride, "Assembled on our new model of UAV, the speed and endurance have been doubled."

"That's great, when we're done with this while, our new headquarters will be built, and it is estimated that we will have to get a few engines from you to play", Wang Yinan said half-truthfully,

"It's the aerospace plane you talked about last time, and then I went back and found a few senior experts to talk about your plan, and everyone thought it was very feasible", Chief Engineer Yang nodded,

"How about it, when your project starts, we will also take some shares?" ，

"That's not what I said, the engine originally depended on your achievements, and it was impossible to leave you alone for such a popular project", Wang Yinan agreed.

"Let's go, take a look at our auspicious dragon, if it weren't for the endurance problem has not been completely solved, this is the perfect civilian drone", Chief Yang took Wang Yinan to the airport, and sighed regretfully while walking.

In the hangar next to the airport, there are two Xianglong drones that have just left the factory and are ready to take a test flight, with a sky blue base and a white striped paintwork, which is about to be delivered to the Navy at a glance.

However, what Chief Master Yang said was not wrong at all, the slender figure, after spraying stealth paint, looked smooth and abnormal, it was simply a good look, Wang Yinan couldn't help but walked over and touched the smooth skin,

"Now your level of craftsmanship is amazing", Wang Yinan said,

"I don't think even the latest fat man lightning in the rice country doesn't necessarily have our craftsmanship."

"That's, this is nothing, it's just a part of the automated production equipment, there is a chance to take you to see the pulsating production line of the new model of stealth fighters, fully automatic robot installation, if it weren't for the number of pilots in the army can't keep up, one production line, we can burst out four planes a month",

"Anyway, you are also your own person, take you to see if it is not a violation of discipline".

If it were usual, Wang Yinan would definitely shout to take a look, but when he saw the ready-made artificial muscles, his hands itched, so he couldn't take care of this for the time being.

Climbing up a simple escalator, Wang Yinan carefully observed the solar panels on the upper part of the fuselage. Densely laid piece by piece on the wing of the drone, it looks shiny.

"I see a lot of solar power stations on the ground, the panels are controllable, and they will adjust the angle with the sun's rise and west setting to ensure that they are always facing the sun, but ours seems to be fixed", Wang Yinan asked,

"Yes, this is also the fundamental reason why the power generation efficiency of solar panels is not enough, when it was estimated before, it was based on the efficiency of the panels of the ground solar power station, and it was originally thought that the high-altitude sunshine was stronger, and the power generation efficiency should be higher," said Chief Engineer Yang.

"Yes, I think it should be the same way", Wang Yinan echoed,

"But we all ignore an important issue, which is the angle of sunlight, in fact, because the panel cannot face the angle of direct sunlight, the efficiency of the panel decreases very much".

"The problem of angles, the loss of power far exceeds the benefits of strong sunlight at high altitudes, so it is impossible to cruise for a long time," said Yang.

"I'll just say, it seems that we have estimated it before, but I didn't expect such a problem", Wang Yinan finally understood where the problem was,

"Is there a way to make the angle of the solar panel adjustable?" , Wang Yinan asked,

"That will greatly change the aerodynamic shape of the aircraft, and whether it can fly is still a question," said Chief Engineer Yang.

imagined the appearance of the panels on the wings staggering to the sun, Wang Yinan had to agree, this thing may not be able to fly.

"How about covering the battery board with a cover", Wang Yinan began to open his mind again,

"Then how do you fly", Chief Master Yang retorted casually,

"I remember that you also have a flying wing design, and it seems that the thickness of the flying wing itself is not small," Wang Yinan said.

"It should be fine to make a thick wing and make it transparent."

"In that case, the strength of the wing is not enough," said Chief Engineer Yang.

"What kind of strength do you want, there's nothing else in it except the panel, how much can it weigh?" , Wang Yinan scoffed,

"Our planes don't burn oil, so we don't need to put so much fuel in the wings."

Chief Master Yang slapped his thigh, "I'm X, maybe your bad idea is really good, I have always ignored it before, our wings don't need to be fueled, and the requirements for strength are very low."

"And a lot of composites are inherently transparent, so they couldn't be better for wings."

"It seems that Boeing and Airbus have envisioned a fully transparent cabin, and they should use transparent composite materials, which are not necessary for the fuselage, we can just use them for the wings," Wang Yinan said.

"It makes sense, there is nothing in our current wing, just a landing gear cabin, but this can be modified and placed on the fuselage", Chief Yang has begun to design a specific plan,

"Choosing the thickest airfoil, this problem is not big, our aerodynamics laboratory has long stocked hundreds of airfoil designs with different performance, you can find a more balanced one",

"The upper part is made of transparent materials, the panels are divided into small pieces, each of which has its own independent steering device",

"This can be made self-consistent, each panel tracks the trajectory of the sun by itself, and automatically adjusts its own angle, so that it is not affected by system failures, even if some of them are broken, it will be fine," Wang Yinan added on the side.

"The steering device that comes with the panels, as well as the thickened airfoil, will increase the weight, and the aerodynamic efficiency should also be slightly reduced, which will increase the power consumption," said Mr. Yang.

"But adjusting the angle of the solar panel should at least double the efficiency of solar power generation, so that it is very likely to achieve the effect of filling the battery during the day," said Mr. Yang, the more excited he became.

"In that case, it will be the first fully self-sufficient solar-powered aircraft in the entire Blue Star",

"Yes, the Stratoplanar Prowler program will be officially launched," Wang Yinan said.

I believe that with the excellent performance in the South Pacific and the Navy's orders, there should not be much resistance to the implementation of this plan now.

"After such a big change, it is not appropriate to call it Xianglong, this should be a new aircraft, for the sake of you having such a good idea, the naming will be left to you", Chief Engineer Yang reciprocated the favor and said to Wang Yinan, "Hurry up and give the new plane a name",

Wang Yinan pondered for a while, "This should be the first aircraft in the entire Blue Star that can have unlimited endurance, and it is also a drone that relies on the sun to fly."

"Let's call it Apollo, take a foreign name, maybe you will have better luck in the future",

Don't say it, to the extent that Chief Master Yang or Wang Yinan and them will more or less believe in something indescribable, at least ask for a good mouthpiece, Chief Master Yang nodded, "Yes, take a foreign name, let's call it the Sun God."

Solved the matter of the Xianglong, no, it should be called the sun god now, Wang Yinan was not in a hurry to return to the imperial capital.

Shudu is located at the junction of the Hengduan Mountains and the Bashu Basin, less than 60 kilometers away from the city center, to the Longmenshan fault zone, which is the easternmost part of the Hengduan Mountains, that is, the easternmost part of the roof of the world.

From the basin at an altitude of tens of meters, it suddenly rises to the roof of the world at an altitude of thousands of meters in a short period of time, and the unique geological conditions have caused many mountains around Shudu, and most of them are high mountains covered with snow all year round, such as Gongga Mountain, the king of Shu Mountain.

Although the altitude of Gongga Mountain is only 7,556 meters, the foot of the mountain is only 1,000 meters above sea level of the Dadu River, and the height difference from the river surface to the top of the mountain is more than 6,500 meters, and its majesty can be seen.

Wang Yinan came to Hailuogou in the south of Gongga Mountain, where there are hundreds of thousands of years of glaciers and hot springs, which is a good place to cool off.

Wang Yinan was not in the mood to cool off, he soaked in the hot spring beautifully, and the smart head on the blue star began to overclock again. Then the artificial muscles of the anti-heaven are already in place, coupled with the compilable neural network of the more anti-heaven Gödel system, if there is no more anti-heaven bipedal robot, Wang Yinan can find a piece of white and tender tofu.

I knocked myself to death.
