Chapter 14

"If the drone flies in a circle of several hundred meters in the same place, the position is basically fixed for the drone in another cellular center hundreds of kilometers away."

"In this way, the transponder can be customized into a regular hexagon, and it will communicate with the drones of the six nearby cell centers in exactly six directions."

"Anyway, there's no need to think about it so carefully now, you've thought about it, what should your big group of subordinates do", Wang Yinan interrupted Chief Yang's train of thought,

"I think you're just lazy", Chief Master Yang immediately pierced Wang Yinan's true thoughts,

"I call this full decentralization", Wang Yinan said vigorously, "only in this way can subordinates grow faster."

"That's right", Mr. Yang rubbed his hands and said a little embarrassed,

"Your stratoplanar, do you want to invest a little bit and take a little stake in 116?"

"Damn, are you greedy or not, the order of hundreds of planes is not enough to feed you, and you still expect to occupy a position in the upstream industry?"

"Of course, you know, the 116 Institute has been short of time and talent recently, but there is no shortage of money", Chief Yang said that he was a local tyrant.

"I don't care about this matter, it's up to me, I'm sure I'll have no opinion on taking you a little stake, so that at least you will do your best to build an airplane."

Wang Yinan pointed to the sky, "I guess, in the end, the major shareholder can't be me, it must be the top, take you or not, you have to listen to them."

"That's that, the airspace is the biggest resource, take the airspace to buy shares, in addition to the top of the top, I will ask who else", Chief Master Yang nodded in agreement, this matter is indeed in the end, it is impossible for Wang Yinan to have the final say.

"There is also a key problem, that is, the choice of routing", as a senior technical master, it is impossible to give up without clarifying all the technical links that may be in doubt.

"Hundreds of drones, or to put it mildly, hundreds of nodes are connected to six nearby nodes, and then any device that logs in to any one of the nodes needs to transmit data to another device that logs in to any one of the other nodes," said Mr. Yang.

"Come to think of it, the path choice here must be an NP complete problem (a question that cannot determine whether the answer can be obtained in polynomial time)",

"It's not that complicated", Wang Yinan has obviously been fully considered,

"Just choose the nearest road, for the situation where there is different traffic and congestion, we can introduce abstract distance, abstract distance = physical distance + congestion degree * congestion coefficient",

"You can get a good path by directly searching with a local-based greedy algorithm," Wang Yinan said.

"Of course, if the complexity increases, or if necessary, the optimal solution should be obtained using the Gödel system's neural network to find the optimal solution."

"It's still your cow", Chief Yang admired it very much,

"When it comes to software, I don't have a say."

Seeing that there was basically no doubt about Chief Master Yang's side, Wang Yinan also specially advised,

"This matter must be kept strictly confidential, even if the development task of the drone is really issued in the future, the relevant information of the payload cannot be disclosed, for you inside, this is just a drone",

"Of course, we are much stricter than you in terms of confidentiality discipline, so we don't need you to worry about it here," replied Chief Master Yang.

After talking about the matter, Wang Yinan remembered that there was another very important thing, and he asked Chief Master Yang,

"I heard that you participated in the research on an advanced turbofan engine with a small bypass ratio?" ,

"No, you even know this", Chief Master Yang had an unbelievable expression on his face,

Wang Yinan smiled embarrassedly, "I still have a few friends at the Institute of Engineering Thermophysics of the Academy of Sciences."

"That's right, it is indeed a one-ton thrust turbofan engine jointly developed with them, you know, we have not been bitter by the engine pit from the No. 9 project, to the No. 10 project, all the way to the latest No. 20 project", Chief Engineer Yang said about the engine, it was a handful of snot and tears,

"So we have no choice but to be a little more involved in the development process of the engine, so that at least, we have to die to understand whether it is not",

"The new high-temperature resistant materials developed by our joint materials laboratory are also used in this engine first," added Chief Engineer Yang.

"What are the technical indicators of this engine, mainly depending on the temperature before the turbine and the thrust-to-weight ratio", Wang Yinan asked.

"Yes, the question is very professional, I have a little doubt that you are a spy sent by the rice country", Chief Master Yang joked,

"With the new high-temperature resistant coating, the pre-turbine temperature can reach 2000 K, and the thrust-to-weight ratio is close to 10 bar."

"It's amazing, this performance index is close to the F135 of the rice country", Wang Yinan said,

"If you don't consider the thrust, it's close, but people don't have 13 tons of thrust without afterburner, and we are still far behind", said Chief Engineer Yang.

"Of course, the new materials developed by our joint materials laboratory can effectively increase the operating temperature and reduce the weight of the engine, so the future is still very bright."

"The thrust of the next model will be extended to two tons, and with twin engines, our Kazekage will be able to use its self-developed engine, and its performance will definitely be greatly improved."

"To further improve the thrust and thrust-to-weight ratio, the simulation of the combustion chamber is a big problem", Wang Yinan asked, I have never eaten pork, I have never seen a pig run, the atomization and combustion of fuel under such extreme conditions must be the nightmare of any large-scale simulation software, otherwise, why is the research and development of the engine so expensive, because a lot of data, computer simulation can not be simulated, it must be manufactured one by one, different temperatures, different shapes of the combustion chamber, continuous weeks or even months of testing.

This burns money every second, so on the entire Blue Star, there are only two players with super-large thrust and large bypass turbofan engines, Luo Luo and Pratt & Whitney, for no other reason, it is too expensive to burn.

"Yes, this is a bottomless pit, no amount of money is enough, and at least half of our profits last year were burned in", Chief Yang had a painful expression on his face.

"You guys are really pigs, let me ask you, what is the difference between the combustion of fuel in the combustion chamber and the wind tunnel of the aircraft, except that it is more complicated?" , Wang Yinan said,

Before he could finish speaking, Chief Master Yang interrupted him, "It's not a little complicated, it's a lot more complicated, it's completely different from the wind tunnel, after all, there is a combustion reaction, and the composition of the substances in the combustion chamber is changing anytime and anywhere."

"For the Gödel system, complexity is not a problem at all, uncertainty is," Wang Yinan said complacently.

"Although the combustion chamber is complex, it is still a closed environment after all, and the physical laws in this closed environment are known, whether it is combustion or air flow".

"So, the Gödel system will definitely come into play",

Chief Master Yang almost didn't spurt out a mouthful of old blood, "You, you, you, why didn't you say it earlier",

"Cut, you didn't tell me when you studied the engine, if I hadn't asked my friend more, who knows what kind of fame you are doing", Wang Yinan is very disdainful, you are stupid, you can blame me,

"Professor Wang, Brother Wang, look at this trouble, my little gadget, if I can pull you to join, it must be a brilliant flower", Chief Teacher Yang immediately accompanied the smiling face,

"Why don't you count this little engine research project into you?" ,

"You have the final say in this matter", Wang Yinan asked,

"Of course, at present, 70% of the funds are provided by us, and now our 116 Institute is the major shareholder and the only user, and it must be me who has the final say", Chief Yang began to take care of the package.

"But then again, why don't you mix with aero engines, the superconducting piece is not enough for you to toss?" ,

Wang Yinan smiled mysteriously, "I will definitely mix the aero engine",

There was still half a sentence, Wang Yinan held it in his mouth, and he didn't say, "As the first step to fly into space, you have to fly to the sky first."

"Okay, then I'll be reluctant, participate in your small turbofan engine project, let's not talk about the specific conditions, hurt feelings, I'll let Zhang Qi come over, go back and bargain directly with your business leader."

"That's the best, if you want to talk, I will definitely be taken into the pit by you", Chief Master Yang was happy, "I didn't expect you to be a kind person."

"That's it, cooperation, it's a win-win situation", (it doesn't make much sense to bully an honest person), Wang Yinan said happily.

After completing the implementation of the Stratoproper plan with Chief Engineer Yang, the details are generally similar to what Wang Yinan had envisioned before he came.

Of course, the most important thing is the cost, although Mr. Yang has always claimed to be an honest man, and he is indeed an honest man, but as the chief engineer of a large research institute, and in the research and development system, the chief engineer is basically on an equal footing with the director.

Before the time came, Wang Yinan thought to himself, when it was really time to negotiate the contract, "If you don't cut half of it, I'm so sorry for you."

After chatting about business, Chief Master Yang had to invite Wang Yinan to an authentic Shudu hot pot, "I've come so many times, I haven't invited you to eat yet, let's not go to those high-end places with empty heads, just nine-spice hot pot",

Wang Yinan was happy, "Okay, let's just Jiuxiang hot pot, but then again, I am an authentic Shu Province, it stands to reason that I should be the landlord."

"But I won't rush to pay the bill with you, I have to give you a chance to get married to the God of Wealth."

Inside the hot pot restaurant, there is a foreigner singing "hot pot" vigorously, and the magical melody makes Wang Yinan can't help but hum "I love hot pot, hum haha",

Everything is ready, Wang Yinan is ready to go back and prepare materials to apply to the above, it seems that there should be no big problem, but Wang Yinan has a good habit, every time before a major event, he will always go through it comprehensively to see which link will be possible omissions.

Let's put aside the approval or not to approve from above, this is a force majeure, there is no way to do it, specific to the implementation of the plan, there are probably so many links,

Aircraft, the reputation of the 116 Institute in this regard is good, and the relationship between the two sides is iron enough, and there is no possibility of problems.

Superconducting motor, this problem is not big, with the existing technology of N University, with the help of new superconducting materials and Gödel system, if only double the performance, Wang Yinan feels embarrassed to go out to meet people.

Battery panels and lithium batteries, not to mention the 116 commitment to get it, with the existing degree of industrial development, you can find a bunch of suppliers at any time,

There is also a "signal transponder", Wang Yinan put down his chopsticks, and there were words in his mouth, and finally found out where the faint uneasiness in his heart came from.

This Dongfanghong Co., Ltd. has never dealt with before, and I don't know what kind of style it is.

And the price of the transponder, Wang Yinan hasn't had time to ask, this is not a simple purchase, but a simplified design in accordance with the way of reducing weight and reducing indicators, and it is not an exaggeration to say that it is not an exaggeration to re-develop, aerospace mouth, that is a rich man who takes money seriously, just hit a rocket into the sky, you have to get hundreds of millions of soft sister coins, not to mention satellites, the cost is one billion, you have to thank others, the knife is not so ruthless.

Although Wang Yinan confidently estimated the two million soft girl coins for electronic devices just now, but after thinking about it carefully, with the habit of these guys having a big business and catching one count, Wang Yinan had to label the price of the final transponder as extremely unoptimistic in his heart.

It should not be surprising that the transponder of a drone is estimated to cost 100 million, in that case, the cost of the entire plan is estimated to exceed the military's budget, and Wang Yinan himself can't afford to pay for it.

Looking at the steaming hairy belly and luncheon meat in the hot pot, Wang Yinan suddenly lost his appetite at all. 8)
