Rebirth 2008: I Can Make Money Reading

a week later,

Han Li reported the XH-AN05-01J engine test situation to Mu Yang.

With 50% afterburner, it can continue to fly, as long as there is enough fuel;

Therefore, fighter jets equipped with this engine already have supersonic cruise capability, and can continue to fly at supersonic speed for a long time.

When the afterburner is 65% and the automatic control is turned on, the temperature alarm will be triggered after a maximum of 22 seconds. After inspection, no damage is found to the equipment;

Without automatic control, it can last up to 52 seconds. The combustion chamber is damaged and the bobbin is softened. This engine has been scrapped and cannot be used, but some parts can be recycled, and the recycling rate is only about 35%.

The company assembled two more prototypes and continued to conduct destructive tests.

Before conducting a destructive test, a non-destructive test must be performed first. To complete all the tests, at least ten engines must be scrapped.

Mu Yang has some knowledge about the domestic J-20. It does not use a vectoring nozzle. Its engine has been upgraded from the original AL31F engine to a domestic turbofan 10C engine. It is said that it plans to use a domestic turbofan 15 engine in the future.

However, even in 2022, Mu Yang has not heard whether the J-20 is equipped with a turbofan 15 engine. He heard that a binary vector nozzle will be added, which may already be installed. After all, this is a military secret. It is impossible for people to know those inside information.

The maximum afterburner thrust of domestic turbofan 15 engine: 161.865kN—181.373kN, intermediate transition thrust: 105.22kN;

The performance parameters of this engine are indeed not as good as the F135-P-100, which is a big difference.

Of course, the J-20 has made breakthroughs in many aspects such as situational awareness, information confrontation, and coordinated operations, and it is considered very advanced today, but its cost exceeds 110 million U.S. dollars.

This cost is estimated by foreign media, maybe not so much, or more, but at least it will cost 60 to 70 million dollars.

More than half of the cost is on the engine. If it is a single engine, the engine cost accounts for 35%-50% of the whole machine. If it is equipped with dual engines, the engine cost exceeds 50% of the whole machine.

Xinghai Group has invested more than 2 billion yuan in the XH-AN05-01J engine, including 100 million yuan in labor costs, about 1 billion yuan in site construction, and several hundred million yuan in equipment and instruments. The manufacturing cost of a prototype machine has not yet been exceeded. According to statistics, it is estimated to cost two to three million yuan.

It is estimated that billions of dollars are needed to complete this project.

Of course, the site, equipment and instruments will all become fixed assets, but Muyang's research and development expenses are not included. After a miscellaneous estimate, it will take nearly 20 engines to pay back the cost.

This kind of high-risk investment project, if there is no investment return of more than five times, it will lose money, and no one can guarantee that all projects invested will make money.

That is to say, if the total development cost of the XH-AN05-01J engine is 5 billion yuan, then you have to earn 25 billion yuan to pay back the cost, not 5 billion yuan. After all, other similar investment projects may basically fail. The money earned by the project fills in the money-losing pits of other projects.

Therefore, the commercial life cycle of an engine is very long, and it is still being sold after being sold for more than ten years, and the price will not drop much. During this period, the update and optimization are not great.

Of course, there is basically no risk of failure in the projects invested by Muyang, so if you earn billions, you will get back your capital.

During this time, Mu Yang was thinking about what would happen if the domestically produced fighter jets were equipped with XH-AN05-01J engines. Short-term supersonic flight can be turned into long-term supersonic flight, and the speed is faster;

The J-20 can fly with small turns and high angles of attack, which depends on the pilot's superb technology. After it is equipped with the XH-AN05-01J engine, because it is equipped with a three-dimensional vector nozzle, it can be transferred from multiple angles, making it easier to avoid missiles. On an aircraft carrier, even if you don’t rely on boosters, or even run on the ski-jump deck, you can take off tens of meters and land more easily.

if fighter front

The end is equipped with a lift fan, which is sufficient for vertical takeoff. More fuel-efficient engine, longer battery life.

All of the above are qualitative changes! It directly changes the battle situation!

Therefore, advanced engines are the core of fighter jets.

Mu Yang is also thinking, and when the time is right, he plans to dedicate it to the country.

However, it is estimated that the country will not be able to manufacture it for a few years, so the Xinghai Group reluctantly helps manufacture it, and recovers some costs by the way.

On September 15th, Mu Yang summoned eight of his students in his office, and had something to explain to them.

"Using drones as a carrier to learn aerospace knowledge, although you have developed to the third generation, there are still many problems, such as flying fast enough, not high enough, tracking, positioning, remote control, telemetry and digital transmission, etc. There are many problems in all aspects, and it is very difficult to complete it with just a few of you.

How about this, Xiaohan and Xiaowei, it’s time for you two to independently lead the project. With the unmanned fighter jet as the project, you can go to the personnel department to find the personnel you need, but you can’t dig the core personnel of the company’s core projects. "

Mu Yang's words surprised Leng Han and other students.

Especially new students like Chu Yun, Zhan Shengcai and Xiao Dejie. They didn't understand Mu Yang's temperament, and they sat on the sofa straight up, feeling like they were on pins and needles.

The three of them never imagined that the teacher gave the students such great power.

"Thank you teacher, how many people can you pull at most?" Leng Han smiled all over his face, it would be much easier if he could pull people. Mu Yang asked, "How many people do you think will be needed to complete this project?"

"It depends on the project requirements. If it is the previous project requirements, if there is no teacher to guide, I am not sure; if there is a teacher to guide occasionally, uh, I will need another twenty or thirty people." Leng Han felt like a lion.

The teacher set a development goal for their project before, requiring a maximum take-off weight of 2 tons, a load of no less than 500 kilograms, a ceiling of more than 10,000 meters, a cruising speed of more than 800 kilometers per hour, and a minimum range of 4,000 kilometers. It is mainly used for reconnaissance.

It is not clearly stated that it is used for military affairs, but as long as it is loaded with missiles and explosives, it will be transformed into a military fighter.

Leng Han and Jin Wei know that the Xinghai Group has more or less a cooperative relationship with Junfang, so they don't have to worry about being locked up in a small black room if they develop it, and it's not developing weapons such as missiles.

"Let's finish the previous project first and then talk about other things. I will add requirements on the basis of the original project.

For the project of 30 people, make a small fuss. You can handle it yourself. If you don’t have enough people, you can apply again. Drones are also a core project in the company. Since you have done a good job in the early stage, you will be in charge. You can apply for one billion The funds are used as research and development expenses, and if the results are produced within five years, the application amount can be increased;

But if there is no result within five years, it will stop here. "

Xinghai Group will enter the field of drones in the future, Mu Yang has no time to do this now, let the students lay the foundation first. If it is at the level of technology like Dazhuan, one billion R&D funds are enough.

But Muyang has higher requirements, it is not a propeller drone, it has many limitations, but one advantage is low cost.

Instead, it requires long-range combat capabilities, and the minimum requirement is the ability to lure enemy missiles and launch missiles. This kind of unmanned fighter jet costs less than 10 million yuan.

The cost of fighter jets is extremely high, one is nearly 100 million U.S. dollars, and the pilot is more difficult to train. Although the performance of unmanned fighter jets is far inferior to that of a human-piloted aircraft, it is low-cost, and several drones kill a real person by suicide. Pilot a fighter jet that's worth it.

"A billion?"

Leng Han and other students were shocked, the teacher is really generous.

Leng Han asked in embarrassment: "Teacher, are you really giving one billion research and development funds?"

"You have to bear the salaries and welfare expenses of those scientific researchers. Xinghai Group's labor costs are not low. On average, each mid-level engineer costs two to three hundred thousand yuan, senior engineer about half a million yuan, and experts millions. After five years, This fee is not low."

Mu Yang smiled, the salary is not so much, but if you count the year-end bonus, he is considered less.

Leng Han's eyes widened after hearing this, and after careful calculation, Gulu

Whispering: "Based on this calculation, if there are no results for a few years, the funds don't seem to be much."

When Mu Yang heard her words, he reminded: "It's hard to do anything without a billion-dollar investment in this project, and this is the case when you can borrow the company's resources.

You have to change your thinking. One of the problems that cannot be ignored by drones is cost. If the cost of a drone is more than 10 million yuan, it will not be worthwhile.

You should pay more attention to this project. Now we are at the historical node of information war and intelligent war. In the future, machine main battle and intelligent unmanned equipment will be the main combat force;

Group advantages and large-scale group operations are the main combat styles;

Extreme combat, breaking through the limits of human physiology and thinking, and realizing all-time, all-weather, full-spectrum, and all-field operations. UAVs will surely have their own world in the intelligent age.

If you master the drone, you also master the world. "

He intends to let a few of them take over the projects independently. If the one billion projects can't be done well, there will be tens of billions or even hundreds of billions of projects in the future, how can Mu Yang rest assured.

Leng Han and other students were very excited when they heard the boss's words, especially the phrase "control your own world", which made people excited. It turned out that the teacher also valued this drone very much.

Mu Yang went on to say: "Besides the matter of this project, we must not leave behind the study of nuclear technology. This is your future, and it is more important than drones.

Mastering nuclear technology, especially controllable nuclear fusion, surpasses aviation and enables interstellar travel. This is the general direction of your studies. If you are confused, you can come to talk to me. "

Now he can only use the nuclear technology of System 7 to teach students, which is more advanced than the nuclear technology on Earth.

If you really want to study nuclear technology, you have to find another place to build a nuclear research institute. It must not be built in City H. Mu Yang is really afraid that one day the laboratory building will be accidentally blown up.

To study nuclear experiments, it is best to have an intelligent robot, otherwise Mu Yang is not at ease.

Mu Yang told the students about the project, and then explained to the students: "Chu Yun, Zhan Shengcai, and Xiao Dejie, you three should learn from Leng Han and Jin Wei first. In the next year, you should first lay down the basic knowledge, and then get in touch with professional knowledge. , I will give you a tutorial when I have time." "Okay, teacher."

Chu Yun, Zhan Shengcai and Xiao Dejie said respectfully.

Mu Yang nodded with satisfaction. When he taught students knowledge, he could do one-to-n.

"Well, if there's nothing else to do, let's go get busy." Mu Yang drank his tea and began to chase people away. He still had other things to be busy with. Leng Han waited for the students to be interesting, and left the chairman's office with a smile.

the next day,

Mu Yang resumed his daily work rhythm.

Review the work documents compiled by the secretary in the office, and go to the implementation room to inspect when you have time to help solve some tricky technical problems.

When you are free, just read the news reports pushed by the public relations department. There was a report that caught his attention.

"CFM International announced that it will cut off the supply of engines. Is the domestic large aircraft going to be "cool"? "Seeing this report, Mu Yang was a little surprised, is it true or not?

He has been busy with the laboratory work recently, and has no time to pay attention to the outside news. Why did this big news break out in just a few days.

Perhaps to others, cheating by a certain star is considered big news, but to researchers like Mu Yang, they are more concerned about matters at the national technical level.

Mu Yang continued to read patiently. The content of this article reads as follows:

"On September 15, 2015, under the influence of Ugly China, CFM International announced that it would stop supplying LEAP-X1C turbofan engines to Huaguo SAIC.

Previously, Shanghai Aircraft Corporation has successfully tested many times. When it is about to obtain the airworthiness certificate from the Civil Aviation Administration, the C919 has completed the first six links, which are the most difficult and time-consuming. Moreover, the first customer of the C919, DONG Airlines, last year The aircraft purchase contract has been signed with Shanghai Aircraft Corporation, and many media outlets have reported this happy event overwhelmingly, and the senior executives of Shanghai Aircraft Corporation are full of joy.

but can't think

Come on, extreme joy begets sorrow....."

After reading the report, Mu Yang probably understood the situation.

In this life, with the help of Mu Yang, Shanghai Aircraft Co., Ltd. made the first flight process much faster. It was a few years faster than the first flight in 2017 in the previous life. Just like this, Shanghai Aircraft Co., Ltd. planned to obtain the airworthiness certificate from the Civil Aviation Administration. year time.

If the airworthiness certificate is obtained, it means that the order can be officially delivered to the customer.

The stand-alone price of the C919 is US$99 million. It is a strong competitor and will have a great impact on Airbus and Boyin.

When Shangfei Company was about to obtain the airworthiness certificate, Ugly Country came to a bankrupt plan, restricting CFM International Company from selling LEAP-X1C turbofan engines to Shangfei Company.

It's not that the senior management of Shangfei Company is ignorant of this risk, but they have no choice and are very helpless. They thought that Ugly Country would not spoof them so quickly, but they didn't expect the blow to come so quickly.

"Hey, the more you worry about something, the more you come."

Mu Yang also sighed, it is estimated that the senior executives of Shangfei Company are not in a good mood at this time.

Picking up the teacup, he took a sip of the tea, pondered for a while, and then picked up the mobile phone to ask Academician Wu, the chief designer and deputy general manager of SAIC.

At this time, after receiving the notice from CFM International yesterday, the top management of Shanghai Aircraft Company was immediately disheartened, feeling that all previous efforts were in vain, and how much time would be wasted.

Especially Academician Wu, his hair turned gray overnight.

Not only Academician Wu, but all the employees of SAIC felt that the sky was falling, which hit them too hard.

Of course, it doesn't mean that the efforts over the years are useless. After all, many technological breakthroughs have been made in these years, and many parts have been made in China.

However, if the engine cannot be obtained, the plane will lose its heart, and the signed order will be invalidated. Where can they go to buy a new engine.

Once bitten by a snake and afraid of well ropes for ten years, it is impossible for SAIC to import engines from Europe and the United States. Apart from this, it can only find a way from Xiongguo in the north, or wait for domestic engines.

The development of domestically produced engines has not been smooth, and it will not be available within seven or eight years.

Even if you buy a new engine, the dimensions and performance parameters of the engine are different, and it may not match the original model. If the problem is serious, you will have to redesign the aircraft. If you are lucky, you may only need to correct the engine installation position.

In this way, no matter whether you are lucky or not, you have to go through the procedures for obtaining the airworthiness certificate again. The first flight and the approval review representative will verify the prototype of the aircraft and get the type inspection and approval certificate TIA. Re-approval test flight, and finally obtain the type certificate TC, that is, the airworthiness certificate.

Academician Wu came to work in the company today, but he sat in the office without sitting, just sat quietly, his slightly red eyes stared at the announcement of CFM International, and his face was expressionless.

what to do? !

He has been thinking about this question in his mind since yesterday. A sleepless night.

Employees throughout the company were listless, and he went to the offices to reassure researchers that they should not be discouraged. But who will comfort him.

Suddenly, his phone rang.

This morning, there were many incoming calls, but he didn't answer them, so he just hung up.

Academician Wu turned his head slowly, and was about to hang up the phone, but after seeing the note "Xinghai Group Mr. Mu", he didn't dare to hang up the phone. He answered the phone anyway, and said politely: "Hello, Mr. Mu."

"Hello, Academician Wu, I just saw a media report that CFM International announced that it would cut off the supply of C919 engines. Is this true or false?"

"Mr. Mu, you know it too. It's really bad news that spreads thousands of miles. It's true." Academician Wu sighed again. He didn't know how many times he sighed. If sighing can solve the problem, he would rather sigh. All year.

"Hey, I didn't expect to come so soon."

"Mr. Mu, you have warned me before, and we also know that there is such a risk, but we didn't expect that the storm would come so quickly."

"You now

Is there any solution? "

"No, the fighting spirit of the whole company is gone. As the chief designer of the company, my head is completely swollen now. It's all my fault."

"Academician Wu, it's not easy to develop domestically produced large aircraft. You have made great progress in the past few years, and you are restricted by Western countries. The responsibility for this does not lie with you, and you don't have to blame yourself too much." At this time, Mu Yang didn't want to put He revealed to reporters that the Xinghai Group has developed a civil aviation engine.

Helping Shangfei Company is not so helpful. UU Reading www.uukanshu.com is a disaster. He wants to let the whole country see it, and let all the employees of Shangfei Company understand that the ugly country is not reliable, and let these people After going through a mental and will training, I was not hurt, and my memory is not deep enough.

Next, maybe SAIC will go through the national business process to see if it can save the situation and change the ugly country's thinking.

Yes, they must still be thinking that way.

The higher authorities attach great importance to the domestic large aircraft project, and several super bosses have visited Shanghai Aircraft Company many times.

If Mu Yang offered to help at this time, revealing that he had developed a civil aviation engine, it would really not be a good thing. This lesson is meaningful only when the top management of Shanghai Aircraft Company experienced being rejected by the Ugly Country and despaired.

Instead of helping others, let them cheer themselves up first.

In addition, the incident happened just now, and he didn't know if there were any other tricks from the ugly country. He was waiting for the opportunity. "Mr. Mu, thank you for coming to comfort me."

"You're welcome. I also hope that the domestically produced large aircraft will soar in the international sky as soon as possible. Since we have already expected the day when the Ugly Congress will do this, I hope that Academician Wu will cheer up as soon as possible. As long as everyone is in the same team and the fighting spirit is still there, nothing is wrong. It can be defeated." Mu Yang persuaded, from the tone of Academician Wu on the phone, he could guess that he was really not in a good mood, and after a few polite words, he hung up the phone.

Next, whether they can achieve self-help spiritually and regain their confidence is very important.
