If it weren't for Zhou Hui still driving the car, it is estimated that she would immediately turn around and give Wang Yinan a big hug, or send warm lips or something.

Wang Yinan thought about it, the "Stratosphere Prowler" plan is still missing a very important part, he picked up the phone and dialed Li Gong of a certain institute in Jinling, the development of the UAV transponder has been going on there for a long time, some time ago Wang Yinan set a new goal for them, and now there must be new progress.

Li Gong, due to his outstanding performance some time ago, is now Chief Engineer Li, and happily answered the phone, "Professor Wang, congratulations first, double Nobel Prize, why did you think of calling me today",

"There is good news, you can report the good news to Director Ma when you go back, our Stratoplanar plan has been approved above, and the contract for thousands of transponders is enough for you to be busy for a while."

"Really, such good news should be floating three whites, when do you come to Jinling, I will call Director Shangma to accompany you to have a good drink",

"You can put the drinking thing first, by the way, how was the experiment you asked you to do last time, is it possible to connect directly to the mobile phone?" , Wang Yinan asked,

"Not long after the experiment was completed, it was feasible for the ground mobile phone to be directly connected to the UAV network without blocking, and there was no major problem with the signal strength, but the requirements for the throughput of the transponder were much higher than those of the ground station."

"This is also normal, after all, although the total traffic is about the same, the number of connected terminals has increased by more than two orders of magnitude."

"But after all, we are not a professional mobile communication R & D provider, the test is no problem, but to achieve the actual 4G or even 5G networking, our R & D capabilities are insufficient, even if the R & D capabilities are no problem, there are still a bunch of patent traps in that field, and we will accidentally fall into it", Chief Engineer Li said,

"So it's best to find another partner in this regard, Zhongwei or Huaxing can do it, I suggest finding Zhongwei, after all, they are leading in scale and technology."

"Okay, I know, it's okay if it's feasible in principle, I'll consider who to work with", Wang Yinan thanked him and hung up the phone.

Zhongwei, I should have made a lot of money selling our somersault clouds, this drink and a peck are all determined by God, it seems that it's time to find them to repay me this favor.

Zhongwei's affairs are not in a hurry, Wang Yinan closed his eyes, and was ready to take a good rest, there have been too many miscellaneous things recently, and they have delayed scientific research a little, this is not good, as a well-known scientist whose goal is the sea of stars, it is the king to constantly throw mortals farther and farther away in the field of science, Wang Yinan thought.

Of course, he just thought about it, if he knew that in distant Europa, a person whose IQ had surpassed all the people in the Blue Star, and even had some abilities of the Gödel system, or who could no longer be called a human being, had been born, Wang Yinan's urgency would definitely increase by several orders of magnitude, but unfortunately no one is omnipotent, let alone an omniscient God.

When I came to the lake, it was already dusk, the silver-white dome with a golden light in the sunset, standing quietly on the lakeside, driving along the lakeside path, Wang Yinan opened the car window, a cool wind blew, with a little lake water is very light and light fishy, but it looks fresh and vivid, full of life.

Wang Yinan asked Zhou Hui to park the car by the lake first, "Let's go to the hotel later, take a walk by the lake first."

Zhou Hui put her hand into Wang Yinan's arm, her head rested on his chest, and the two of them walked slowly along the lake, walking, and Wang Yinan's bragging voice came from the lake, "It's not me who blows, now Musk's recyclable rocket, that's a lump of X",

"Why, I look very powerful, such a high place can fall vertically, and stand firmly on the ground, I have watched the video, very shocking", Zhou Huitong shoes asked very interestingly,

"It looks very lively, but in fact, what a waste of fuel, if you want to slow down such a heavy rocket engine, at least 20% of the fuel must be reserved, and with that fuel, how many more things could have been carried," Wang Yinan said.

"And the fault tolerance is too poor, a little surprise will bang bang", gestured, Wang Yinan said with a smile.

"There are two best ways to get back to the ground from high altitude, one is a parachute, and the other is a glider," Wang Yinan explained.

"The parachute should be the lowest-cost way, but the problem is that the landing site cannot be controlled, and the landing attitude cannot be controlled, so it is more suitable for one-time use of the spacecraft return capsule, etc."

"The way of gliding, if you add a certain power engine, it is the best way to control the return, for example, the space shuttle of the rice country used this way," Wang Yinan said.

The sun had slowly set behind the hill by the lake, and the sky was a little dark, and the waterfowl were flying high and low on the shore, and from time to time they swept over the water, stirring up ripples in circles.

"But the space shuttle in the rice country seems to have been grounded a long time ago because of the cost problem, does it mean that this kind of aircraft has congenital defects, so the rice country has also stopped developing", as a scientist in the star, Zhou Hui is not so easy to fool.

"That's because under the technical conditions at that time, the cost and reliability of the space shuttle could not meet the requirements of long-term repeated use," Wang Yinan said.

"Several accidents are material problems, and under the technical conditions at the time, the defense against external forces, such as foreign objects or fuel tank defects, is too poor, and an accident is devastating.

"The combustion chamber, the compressor, these are the two basic components of the aero engine, the rocket engine does not depend on the oxygen in the atmosphere, so there is no compressor", Wang Yinan said,

"In our new engines, the oxygen intake and fuel intake can be adjusted at any time, so through the simulation of supercomputers and the training of neural networks, we can get the best way to work at any altitude (air density) and thrust range".

"That is, the full-state aerospace engine, flying from the ground to the interstellar is not a dream," Wang Yinan said with a smile.

Although she didn't understand very well, Zhou Hui still looked at Wang Yinan with wide eyes, with a look of "You are so powerful", which greatly satisfied Professor Wang's vanity.

The two chatted while walking slowly around the lake, of course, the main thing was that Wang Yinan was boasting, but he had this qualification, seeing that the sky was about to get dark, and in late autumn, the lakeside gradually became a little cooler, "Go back", Wang Yinan said, "I'll call BigMouth again."

BigMouth is an old acquaintance of Wang Yinan, and it is also one of the giants of Zhongwei, "BigMouth, I'm Wang Yinan, I heard that your latest P20P has been released", the call was quickly connected,

"How about it, is there a limited edition with any special color, send two to me to play, you actually got three cameras, so simple and rude, but I like it", Wang Yinan joked,

"No problem, whatever color you want, I'll ask someone to customize it for you", BigMouth is also very refreshing,

"Why don't we just ask you to endorse the next product, and the endorsement fee will be cheaper?" , BigMouth also made a joke,

Wang Yinan was still very tempted in an instant, although it was said that the endorsement fee was cheaper, but after all, he was a global spokesperson, no matter how cheap it was, it would be a lot of money, but thinking of his image as a scientist, Wang Yinan still gave up with tears, and it was already very exaggerated to make a somersault cloud and "Come Hi", and then earn this endorsement fee, the mercenary is the character of a scientist, and it can't run away.

After chatting with BigMouth for a while, Wang Yinan returned to the topic, "When will you talk to your big boss?" ”，

"There are important things," Wang Yinan said.

"Is it important, can you tell me first", BigMouth said,

Wang Yinan thought about it, this is still a bit big, if the equipment that supports 4G and even 5G is put on the drone, plus the existing microwave link between the drones, that is to say, this new company that implements the stratospheric prowler plan can establish a 4G, or even 5G mobile communication network covering the entire country of China in the shortest possible time, at least without the obstruction of buildings, without relying on any existing base station.

In this way, if you let giants such as China Telecom Unicom know, then you can play, and it is better to keep a low profile before the dust settles.

"There's really no way to say, it's a bit big, you can make an appointment for me", Wang Yinan still couldn't satisfy BigMouth's curiosity,

"Okay, I'll help you ask the boss about the time", BigMouth pressed his curiosity and agreed to Wang Yinan's request.

When I returned to the parking place, it was already completely dark, Zhou Hui sent Wang Yinan to the hotel lobby and went to park the car by herself, after all, the two of them are not married yet, according to the laws of China, this hotel has to register the identity of the two people, which is still a little embarrassing.

Wang Yinan booked the hotel with his own name, the quality of the five-star foreign-related hotel is not covered, from the doorman to the front desk, for Professor Wang did not show a little abnormality, of course, there was a little bit of a small situation when checking in, the front desk said very politely,

"Professor Wang, our boss has upgraded the lake-view suite you booked to the presidential suite for free, I hope you have a pleasant stay."

Wang Yinan was stunned, well, it is impossible to refuse such kindness, "Then thank you boss",

Fortunately, this boss is more knowledgeable, and he didn't ask for anything to eat together, which would be too Lo.

After settling in the room, Wang Yinan and Zhou Hui came to the swimming pool of the hotel, swimming in the imperial capital, it is better to choose the swimming pool of a five-star hotel, and the water quality is guaranteed with fewer people (by the way, a hard indicator of the difference between a four-star or a five-star hotel is the swimming pool, a five-star hotel must have a swimming pool, and a four-star hotel is not necessarily), of course, you must have enough money in your pocket.

Although Zhou Hui is a native of Jiangnan, she grew up in a rice country and really can't swim, Wang Yinan is different, she grew up by the river since she was a child, the river water was still very clear when she was a child, and a group of friends all played in the small river ditch.

At that time, there was no swimming training class, and Wang Yinan's father taught him a very simple way to swim, throw Wang Yinan into the river, and find a way to flutter back.

After fluttering like this a few times, Wang Yinan learned to plane, and then looked at other people's useful postures, learned breaststroke, and freestyle.

Wang Yinan is ready to use his family heirloom to teach Zhou Hui to swim.

Apparently, he was overthinking. 8)
