Chapter 601: There is no end to digging holes

The navy is money-burning. It is impossible to build a huge navy without a sufficient economic foundation as a backing! The people of the East still have a long way to go.

With this thought, Neymar felt relaxed.

“Does your navy have any ideas to start building a new aircraft carrier?” Neymar continued to ask.

"Of course, they even wanted to start construction now, but we refused. According to our construction schedule, it is now our turn to build aircraft carriers for football countries. We have to produce them according to orders, so our navy's aircraft carriers have to be released To the back.”

This answer made Sagastres very satisfied: "Yes, we have waited so long for the aircraft carrier to start construction, and we absolutely cannot tolerate others jumping in the queue."

“You said that this aircraft carrier will be launched in a year. Then, will you build an aircraft carrier for your navy?” Neymar continued to ask.

"Then we have to see if there are orders from other navies in the past year." Qin Tao replied: "We produce according to orders. Whoever places the order first will be in line first."

“Then if your navy places an order, what kind of aircraft carrier will it be?”

“Sir, your question is somewhat confidential.” Qin Tao reminded politely.

 Neymar quickly apologized: "I'm sorry, we shouldn't talk about these things."

However, within a few minutes, his topic returned: "I don't know when we can see the catapult. Since you have developed an electromagnetic catapult, it means that the next aircraft carrier will use electromagnetic catapults." Ejection?"

“We are applying for it and may go to see it tomorrow. As for whether our next aircraft carrier will be equipped with an electromagnetic catapult, we don’t know because it is too expensive.”

Qin Tao can’t say that the technology is immature. Are there any products developed by us Orientals that are immature? We have to talk about the price. We just don’t have the money right now. As long as the funds are in place, we can start construction at any time.

“It’s unbelievable that there is an advanced electromagnetic catapult in the East. We can’t wait to see it.” Sagastrese said it sincerely.

Although the St. Paul will use a jump deck to take off, if a catapult is installed on the angled deck, the combat effectiveness of the warship can be taken to a higher level! If they could purchase E-2 early warning aircraft from the United States, their combat effectiveness would be even stronger than the Charles de Gaulle aircraft carrier! After all, the Charles de Gaulle aircraft carrier does not have a stealth aircraft. They plan to purchase Dongfang's stealth aircraft, which will have incredible combat effectiveness.

“So, where do you want to go next? How about going to our Mingzhou Group’s nuclear power plant?”

 “Okay.” Sagastrese nodded.

This day was spent during the inspection. Neymar was also very excited. He was completely convinced that the device of this nuclear power plant was developed for nuclear submarines! Orientals are really thrifty enough. They use this nuclear power plant to experiment with nuclear reactors without wasting energy!

 This also shows that Dongfang’s new nuclear submarine is already in the research and development stage!

This time he came to the East, and he really gained a lot. Once he saw the electromagnetic catapult and brought back the technical information, his trip this time was perfect!

 Full of expectations, Neymar waited for his trip to Huating Golden Sun Motor Company. Before that, he never dared to imagine that the tall electromagnetic catapult was actually developed by such a private sector!

It’s incredible.

“Welcome everyone, I am the person in charge of the entire project. You can call me Dong Gong and I will show you our prototype.” Dong Gong had a cheerful face.

The person in charge of the project is Ma Ming. He is still busy at the Wasteland Village base. It is impossible to come back to introduce him. Moreover, even if Ma Ming comes back, he cannot introduce it to these people. Ma Ming is a national treasure-level expert and cannot introduce it to these people. exposed to public view.

As for this manager, he is just a security guard who stays in the company. He looks very polite and looks like a technician.

 After receiving the news, he quickly got ready and memorized the information given to him thoroughly. Now he is full of confidence.

“Mr. Dong, what technical solution do you use for electromagnetic ejection?” Neymar asked impatiently.

“Of course it’s medium-voltage communication. Do I need to mention this? This is the only feasible solution.” Dong Gong looked very understanding.

 In fact, even if there are no other preparations, only this plan can deceive the opponent to death.

In later generations, the Ford-class aircraft carrier used a medium-voltage communication solution. Facts have proved that this is a big pitfall. Even if a one-to-one model is made on land, it will still be a problem after it is actually installed on the Ford. Constantly, specific data can illustrate the problem. During the design, the design requirement for the electromagnetic catapult was that a failure would occur every 4166 ejections. In fact, a failure would occur every 272 ejections. In terms of the frequency of use of U.S. aircraft carriers, this This means that a malfunction will occur after one day of high-intensity combat and three to five days of normal operation. Of course, this is not the biggest headache. They also use a high-end electromagnetic blocking system. According to the design requirements, a failure occurs every 16,500 blocking times. In fact, a failure occurs every 41 blocking times. This means that the recovery of carrier-based aircraft will become a nightmare.

 Due to frequent malfunctions, the Ford was unable to form combat effectiveness within a few years of being launched.

 The biggest problem is route selection. The Americans went around in a big circle and decided to switch to medium-voltage DC on the next aircraft carrier. However, many years have passed since then.

 Now, since the other party wants to come to inspect, of course, we must tell the other party this wrong line.

 “Why medium-voltage communication?” Neymar asked knowingly.

“The power transmission equipment is simple, the transmission capacity is large, and the energy density is high, which just meets the needs of electromagnetic ejection. If we don’t use medium-voltage AC, then what should we use? High-voltage electricity is too dangerous. Does anyone want to use high-voltage AC?”

Neymar shook his head: "I don't know either. I just heard that there are many technical problems in medium-voltage communication. I wonder if you have encountered any technical problems during research and development?"

The Orientals have begun to make one-to-one prototypes of their electromagnetic catapults. This is something they discovered recently. They have built a long work shed at the base of Wasteland Village, and the catapult must be installed in it!

As for why it is not a steam catapult, of course it can be seen from the accessories. There is no boiler installed nearby, and there is no spherical gas storage tank. Instead, there is an extra transformer. It is obviously driven by electricity.

“There are too many technical problems.” Dong Gong said: “The problem of the energy storage device, the accuracy of the linear motor, and of course the most critical and technically difficult component is the high-power cyclic frequency converter.”

Neymar's eyes suddenly lit up. Yes, you are right. This thing is indeed the most difficult. It seems that the other party is seriously developing this equipment before they encounter the same problem.

 “Then how did you solve it?”

This time it was Qin Tao's turn to speak: "Sir, although the superiors have agreed to our visit, they have repeatedly emphasized not to cause leaks. The questions you have raised are difficult for us to answer."

"Yes, yes, I'm sorry, it's my fault." Neymar apologized immediately.

 At this time, everyone was already standing in front of the scale model.

This model is not a complete aircraft carrier deck, but only the ejection part. There is a thin slit on the flat surface, and there is a model of a fighter jet on it. An expert can recognize it as the J-31A at a glance.

  Nothing can be seen from the model, because all ejection modules are installed under the model, and various equipment are also in closed boxes.

 “Can you demonstrate this model to us?” Sagastrese was very interested.

“Of course you can.” Dong Gong opened the operating table on the side and began to operate.

A sizzling sound sounded. After a few seconds, the energy storage was completed. With a whooshing sound, the model began to accelerate. The numbers on the multi-segment digital tubes on the side also skyrocketed, reaching hundreds of kilometers per hour in a short period of time. speed!

"Including carrier-based aircraft, they are all manufactured according to proportions. As long as they are scaled up simultaneously, they can be used in practical applications." Qin Tao introduced at the side: "Everyone, we have reached the forefront in this technical field. However, high-tech What it brings is a high price, and the price of this electromagnetic catapult is quite high..."

“How much more would it cost to install this kind of electromagnetic catapult on the Sao Paulo?” This time it was Sagastrez’s turn to be tempted.

“Let’s forget it, the price is too high and it’s not cost-effective.” Qin Tao shook his head.

“Money is not a problem. In order to make the aircraft carrier have stronger combat capabilities, we have to give it a try. How much money will it cost?”

 “At least a billion dollars.”

What?

This number of exports made these people instantly dumbfounded. They thought it was expensive, and thought the price would be higher, but they didn't expect it to be so expensive!

 A Nimitz-class aircraft carrier only costs a few billion dollars, but a catapult costs one billion?

"One billion dollars. Fortunately, one is enough for the St. Paul. If a big guy like the Nimitz is equipped with four catapults, it will cost four billion." Qin Tao's words were very indifferent: "There is no way, Xin Technology is just so expensive.”

If the Chinese football people really demand the installation with the support of big financiers, then Mingzhou Group can really satisfy them. It sells a catapult for one billion US dollars. This money is enough for the Navy to make up its mind to start building an aircraft carrier!

 As for technical leaks?

For use by the Sao Paulo, technical confidentiality must be maintained. As long as the other party dares to dismantle any equipment, it will trigger the internal chip and control the equipment to stop. Only Easterners can dismantle and maintain it.

 Besides, I have no experience, so it would be good to equip the St. Paul with one just to practice.

The price frightened Neymar. Even if it was tens of millions, he would dare to accept it. One billion is really unaffordable.

 Actually, the price is really not expensive, you can compare it.

Later generations of the French considered replacing the Charles de Gaulle aircraft carrier and decided to develop a new aircraft carrier with a displacement of 70,000 tons. However, like the Charles de Gaulle, their aircraft carrier catapults had to be purchased from the Americans.

In this era, steam catapults have become outdated, and electromagnetic catapults must be purchased. The Americans quickly quoted a price, and together with various auxiliary equipment, technical support and other services, the entire set price was US$1.3 billion!

Too expensive? You can make it yourself! Can new technology be cheap?

"Compared with steam catapults, the advantages of electromagnetic catapults are huge. It is small in size and does not need to waste precious water vapor." Dong Gong continued: "Moreover, after overcoming the technical difficulties of electromagnetic catapults, , we will also develop electromagnetic blocking cables, electromagnetic lifts, etc. in the future."

Looking at the problem of the Ford, the electromagnetic arresting cable is more serious than the electromagnetic catapult. Now that we are introducing technology to these foreigners, we might as well dig the hole bigger.

 “Electromagnetic blocking cable?” Neymar was indeed interested.

Dongfang is the third country to successfully develop heavy-duty fighter arresting cable technology. Just such a small arresting cable has blocked the navies of many countries. It needs to be strong enough to pull the carrier-based aircraft instead of being pulled. break.

 The country has been solved by one Juli company, which shows how important the progress of basic industries is to the country.

However, the landing of the carrier-based aircraft is not only due to the blocking cable, but also to the hydraulic cylinders at the end of the blocking cable. The function of these hydraulic cylinders is to provide hydraulic damping to pull the carrier-based aircraft to a stop.

From this point of view, there seems to be no difference between hydraulic arresting system and electromagnetic arresting system, and there is no need to specialize in electromagnetic arresting system.

 But when it comes to actual effects, there is still a big difference.

"The current hydraulic arresting system has the same strength for any carrier-based aircraft. Problems will arise. If the damping is not enough, the heavy aircraft will not be able to stop. If the damping is too high, the overload of the light aircraft will be too large. If you want to be able to more To properly meet the landing needs of carrier-based aircraft of different sizes, a more advanced arresting system must be used." Dong Gong continued.

“You make a lot of sense.” Neymar nodded in agreement. This is indeed a difficult problem in current aircraft carrier operations.

In fact, catapults also face this problem. Although steam catapults can adjust the pressure, the adjustment range is too small. It can be sufficient for the ejection of light aircraft and heavy aircraft, but if it is used on a drone in the future, it will simply not be able to withstand it. The powerful impact of the steam catapult caused it to fall apart.

The adjustment range of the electromagnetic catapult is much wider, which can meet the ejection needs of various aircraft.

"The electromagnetic interception system will be more accurate. For example, the landing of any carrier-based aircraft can be input into the computer. In this way, the computer can determine the aircraft type, fuel and ammunition according to the status of the carrier-based aircraft at that time. The remaining situation, landing speed, etc. are calculated to calculate the blocking strength required by the carrier-based aircraft and carry out the most accurate assisted landing." Dong Gong said: "This kind of efficiency is much higher than the original hydraulic blocking system."

Neymar's eyes lit up: "Yes, you are right!"

 At present, the United States is only developing electromagnetic catapults, and has not thought about the benefits of electromagnetic interception!

“After a successful interception, the electromagnetic arresting cable is very simple to reset, and it will soon be ready for the landing of the next aircraft.” Dong Gong became more and more enthusiastic as he spoke: “In addition to these, there is another important role.”

 “What does it do?”

"When the electromagnetic arresting cable stops the carrier-based aircraft, it will convert the landing energy into electrical energy. This electrical energy can be stored in the energy storage device and used to eject the carrier-based aircraft. Therefore, aircraft carriers equipped with electromagnetic catapults , the electromagnetic blocking system must also be used so that it can be matched better!"

Just like a subway station, when it is built, if possible, it will be higher than the rails, so that when the train enters the station, it can slow down when going uphill, saving brake pads. After leaving the station, it will automatically accelerate when going downhill. , this clever use of gravitational potential energy.

 The current electromagnetic interception and electromagnetic ejection make clever use of electric energy!

Hydraulic arresting converts the kinetic energy of the aircraft's landing into heat energy in the hydraulic cylinder and then dissipates it. Electromagnetic arresting converts it into electrical energy. The heat energy can only be dissipated, but the electrical energy can be stored!

These stored energy can be used during electromagnetic ejection. You must know that electromagnetic ejection is quite power-consuming! Even if the aircraft carrier generates a large amount of power, it cannot meet the electrical power required during ejection, so the electrical energy must be stored in advance.

With electromagnetic blocking, the catapult can not only use the electricity generated by the aircraft carrier, but also the electricity generated by the blocking cable. In this way, the power supply load of the aircraft carrier can be greatly reduced!

This is similar to electric cars. Many electric cars have a single-pedal mode. Some even force users to use a single pedal, with no options to modify it. When you step on it, it accelerates, and when you release it, it decelerates.

 What are you doing by braking and decelerating?

Of course it’s for generating electricity!

 When decelerating, the electric motor turns into a generator and generates electricity directly. The generated electricity is stored in the supercapacitor and then charged back to the battery. Therefore, the endurance of this kind of car is greatly improved.

 However, the user experience is not good. If you want to maintain a constant speed, you have to step on the switch, and when you release your foot, it will brake! There is no smooth feeling like releasing your foot on a petrol car.

What’s even more frightening is that over time, the driver will forget the existence of the brake pedal. Usually a single pedal is enough. When sudden braking is needed, the possibility of stepping on the wrong brake pedal greatly increases.

The ideas are all similar, but when used on aircraft carriers, they are almost all advantages. The only disadvantage is whether this thing can be matured. If it is not mature, the consequences will be serious.

But at this time, a window opened in front of Neymar. Even if he could not get more information, just these introductions were enough to make him feel that he had gained a lot.

  Neymar is extremely excited.

For these naval leaders of the football country, it is just a matter of gaining experience. They know very well that they do not have enough financial resources to purchase so much equipment. It is too expensive. The electromagnetic ejection can reach one billion, and the electromagnetic interception is estimated to be three to five Billion, let’s stick to the original design, ski jump to take off, blocked landing or vertical landing, that’s enough!

"Mr. Qin, after reading this, can we go see the fighter jets again?" Sagastres made a request.

"Okay, of course there is no problem." Qin Tao said: "The test flight of the fighter jet is going smoothly, and the first supersonic test flight was conducted not long ago. It's a pity that there is no two-seat aircraft, otherwise I can take you up to have a look."

The sale of aircraft carriers is not isolated. If you buy an aircraft carrier, you have to buy carrier-based aircraft, destroyers and frigates, and finally it becomes a package of arms sales. The Chinese navy had already taken a fancy to the J-31A when it came here last time. , plan to purchase it to provide supporting equipment for their aircraft carrier, so they are also eligible to request to see this aircraft.

Even though they have people like Neymar in their team, Qin Tao can't refuse. At worst, he will continue to fool them.

“There is no two-seat aircraft? What about the pilot training in the future?” Irges was a little anxious.

"None of the advanced fourth-generation stealth aircraft will have a two-seater version." Qin Tao said with a smile: "But don't worry about pilot training. We have advanced cockpit simulators that can fully simulate flight driving. As long as you simulate it from the cockpit After completing a full set of training on the aircraft, you can get on the plane directly.”

With the development of electronic technology, flying is like playing games, and cockpit simulators will become more and more realistic.

Whether it is the F-22, F-35, or the domestic J-20, there has never been a two-seat trainer aircraft. This kind of advanced fighter is quite expensive, and it is too luxurious to train pilots.

“This time, everyone can go to the flight simulator to experience the thrill of a stealth aircraft.” Qin Tao said.

The visit to Golden Sun Motor Company was over, and Neymar was still a little reluctant to leave. Although he got a lot of valuable information, it was all general and lacked specific technical details, which still made him a little dissatisfied.

 It would be great if we could get more technology!

In the car, he glanced at the people seeing him off below.

 Mr. Dong, I remember you and will look for opportunities to bribe you in the future!

 This evening, Xu Zhengyang also reported to Qin Tao.

"Mr. Qin, if we push Dong Gong out like this, they may be concerned about him in the future. What if they want to bribe Dong Gong?" Xu Zhengyang said.

"Buy? Sure, anyway, Dong Gong is just a security guard. If they bribe Dong Gong, they won't get any valuable information." Qin Tao said.

Qin Tao has personally caught several people who betrayed the motherland, and he takes this aspect very seriously. Of course, the advanced technology of the aircraft carrier cannot be leaked, and the people who develop electromagnetic ejection and electromagnetic interception will not be made public at all.

Just after saying this, Qin Tao suddenly thought of something: "However, if they want to bribe, they will have to spend money. If the Americans are willing to pay us some money, it would be a pity not to accept it."

Xu Zhengyang's eyes shone, and he knew that Mr. Qin was thinking of bad things again.

"Let's see, it's okay if they bribe Dong Gong, but the benefits they ask for must be at least hundreds of millions of dollars. After getting the money, they will give them some false information, and then arrange for Dong Gong to work as a security guard elsewhere to avoid danger. Head, for example, Parthia.”

“Mr. Qin, what will the Navy do in this case? Will someone be holding on to this matter?”

Even if it is selling false information, that is not allowed. This is a matter of principle.

“So, let’s report it to the Navy. If the Navy agrees, we will make a 50-50 decision.”

PS: The previous chapter is out, so I’ll add another chapter for you.
