Chapter 576 Technical Discussion on Naval Early Warning Aircraft

Mr. Lin was fooled. He smiled bitterly and shook his head. He looked at Qin Tao with a very helpless look. He originally planned to ask the Navy to provide some funds to help with research and development. This would also reduce some of the burden on the Air Force. Even with liquidated damages, the Air Force needs money. There are many places.

 But now, Qin Tao has proposed a plan that seems fair and reasonable. In fact, it is still helping the navy speak. After all, the research and development of Air Police 2000 has been started from scratch! This technology is the most difficult. Once this technology is figured out, future research and development will just be simple modifications.

However, this plan seems so suitable, so the Air Force can no longer ask the Navy to invest!

Then what’s the point of coming to the Navy for a meeting this time? This is a lonely time!

Wu Shengli was very happy. He knew that Mr. Lin came here with a purpose, but the soldiers came to block the water and the earth covered him. Now that his son-in-law is out, he is even more powerful!

"Our navy does need to develop advanced carrier-based early warning aircraft." Wu Shengli continued: "Now, the radar aspect is left to the 14th Institute for research and development, and we are relieved. The only issue is the frequency of this carrier-based early warning aircraft. Should we go to the United States? The way of man?”

 Now we are discussing specific technical issues.

Choosing different frequencies for different radars requires careful consideration. The Navy's Aegis battleships have been arguing about S-band and C-band for a long time. The final solution is to use S-band for long-range search and scanning, and C-band for target illumination. , that large shield has a large number of S-band T/R components and a small amount of C-band T/R components. This combination solves the problem.

 As for the Air Force’s early warning aircraft, the L-band was chosen.

So, what about the Navy’s early warning aircraft?

The U.S. Navy uses a unique UHF band. If you look at the tuning **** of an old TV set, you will know that this band is the meter wave band allocated for television broadcasting.

This band has many shortcomings. For example, it will be interfered by TV signals. Therefore, when the radar antenna of the E-2 early warning aircraft rotates once, the frequency must be adjusted once to reduce interference. For another example, the measurement accuracy of meter-wave radar is so poor that it must use a large enough antenna to make up for this shortcoming.

But at the same time, this band also has many benefits. For example, the backscattering coefficient of sea clutter in the UHF band is the smallest among all radar bands, which means that it has a strong ability to resist clutter. The clutter reflected from the islands on the water , will be easily filtered out by it. Moreover, it requires a small number of channels. Compared with the transmitting and receiving channels of hundreds and thousands of phased array radars, the radar of this early warning aircraft only has 20 channels, which means that its power consumption is very small!

(As mentioned earlier, the problem of the excessive power of the engine used by the Yak-44 was greatly explained by some readers. The excess power is not used for flight, but to power the radar. Considering that Lao Maozi’s electronic equipment always consumes power It is large, so it is understandable to use an engine with more than 10,000 horsepower.)

It can be said that no one wave band can be used all over the world. It is best to choose different wave bands for different needs. So, should our own ship-based early warning aircraft also use this wave band?

Mr. Wang shook his head in embarrassment: "Leader Wu, if phased array radar technology is used, our meter-wave radar antenna will be extremely huge."

Each T/R component is a separate transmitting and receiving unit. As the wavelength changes, this unit will also change. In later generations, meter-wave radar also achieved phased array capabilities, but this antenna is very Huge, each independent unit is like a large steamer attached to it!

If this thing were to be mounted on an early warning aircraft, the large plate would hold at most dozens of components, which would not be enough at all.

"Furthermore, this also means starting from scratch and re-developing." Mr. Wang continued.

The current technologies are all L-band. If you want to develop S-band, C-band, etc., you can directly transplant the technology. But if you expand it to the meter wave band, you have to develop it again, because this band filters out clutter, etc. All other technologies must be developed from scratch.

Wu Shengli could only acquiesce. The navy does not have huge funds to develop new technologies! It’s better to use ready-made technology.

"Okay, let's stop talking about the radar issue here. Now, let's hear how the 603 Institute's project is going." Wu Shengli said: "With the leadership of the Air Force here, you will report on the transport aircraft project first, and then report on the shipboard Early warning aircraft platform.”

 It's Mr. Chen's turn to speak.

"First of all, we have to thank Mr. Qin. Listening to the comrades who went with us talk about this incident, it makes people very emotional. Mr. Qin's method of turning his hands into clouds and rain is really amazing and made us relaxed. We have obtained a complete set of technical data on the IL-76 transport aircraft, IL-78 tanker and A-50 early warning aircraft platform, which will be of great help to us in developing advanced transport aircraft." Mr. Chen first expressed his gratitude.

In order to obtain this information, Mr. Qin actually collapsed the factory. This method is absolutely unprecedented and unprecedented!

 Old Chen was very excited.

Qin Tao shook his head there: "Mr. Chen, there are so many people sitting here, not listening to you waste your time! Let me focus on the key points, how is the progress of our Yun-20 project?"

  Yun-20?

Hearing Qin Tao's words, Mr. Lin was a little curious: "Mr. Qin, we just named our early warning aircraft Kongjing-2000. Now this transport aircraft, why is it called Yun-20? Wouldn't it be better to call it Yun-2000?"

Qin Tao was also a little helpless. His mouth was too fast and he said it all at once!

However, the remedy is also very simple. Qin Tao only said one sentence and everyone fell into deep thought.

“The reason why we named it this way is of course to commemorate the luck of ten. Our luck of twenty is equivalent to two luck of ten.”



 At some point, the domestic model naming was also confusing. The word "Yun" at the beginning was originally supposed to be a transport aircraft, but "Yun Shi" is an authentic passenger aircraft.

Yunshi is the first large-scale aircraft project in China. It is the same as Lao Maozi’s original idea, which was to allow national leaders to fly aircraft produced in their own country when they go abroad, as a gift to the leaders.

However, if this aircraft is successfully developed, it will be of great significance. The booming domestic civil aviation industry will not need to purchase foreign passenger aircraft and will be completely self-sufficient. Moreover, on this airframe platform, early warning aircraft, aerial tankers, etc. can also be modified, and the constraints faced by the Air Force will be completely solved.

 It is a pity that the Yunshi project ended without any problem, and Mr. Ma also died depressed because of the end of the project.

Everyone is feeling emotional. If this project had been successful, the early warning aircraft and aerial tanker platforms would have been ready. Now they can only be modified on the transport aircraft platform, and the transport aircraft platform has just begun to be developed.

"Yes, it's called Yun-20!" Mr. Lin said: "Old Chen, please continue, how is the progress of this project?"

“After obtaining such first-hand technical information, our project to develop a transport aircraft will be greatly advanced. We are also confident that we will complete the first flight of this aircraft in the new millennium!”

Modifications to the wings will definitely require blowing the wind tunnel, and the stress on the entire body will need to be recalculated. However, developing based on a complete set of Il-76 technical data is faster than slowly starting from scratch. That's a lot.

 Mr. Chen has this confidence.

Mr. Chen introduced the Y-20 project for more than half an hour, from the airframe to the avionics, from the processing of titanium alloy beams to the planning of the engine, etc. Mr. Chen introduced everything about the project. Although the specific person in charge of this project is Tang Gong, a meeting of this level still needs an experienced person like Mr. Chen to introduce it.

“It sounds like the progress is going well. I hope our project can make its first flight as scheduled,” said Mr. Lin.

“Yes, as long as the research and development funds are in place, we can issue a military order.” Chen Lao said.

Hearing the word R&D funds, Mr. Lin frowned: "How much R&D funds do you need?"

 “At least a billion.”

Mr. Lin looked at Wu Shengli again. Qin Tao saw the signs and spoke quickly.

"These R&D funds are not large. If we don't do our own research, we can only purchase them, which is even more expensive. Instead of spending more than a billion dollars to purchase Lao Maozi's second-hand transport aircraft, the Air Force might as well fully support our self-research plan." Qin Tao Said: "Besides, now that the country's strength is constantly developing and military expenditures will continue to increase, our defense lottery sales business will definitely increase this year."

"Hmph, I don't believe that the Navy will not need this level of large transport aircraft in the future." Mr. Lin said: "If the Navy wants to purchase this kind of transport aircraft in the future, then we have to talk about the sharing of research and development funds. .”

 After speaking, Mr. Lin glanced at the naval leader. The meaning behind his words couldn't be more obvious.

“Mr. Lin, have you ever seen that the US Navy has large transport aircraft?” Qin Tao asked.

Mr. Lin hesitated for a moment, then shook his head: "It seems there really isn't one."

"The U.S. Navy has medium-sized transport aircraft such as the C-130, but strategic transport aircraft, whether C-17 or C-5, all belong to the Air Force, and the U.S. Navy has always wanted a variety of aircraft to be on board. They are Carrier aviation." Another leader said.

"Yes, the U.S. Navy operates carrier-based aviation, and our navy will also develop in this direction in the future." Qin Tao said: "In the future, our navy will develop better and better, and we will have more and more aircraft carriers. , by that time, our naval aviation will also develop into a carrier-based aviation, and we will no longer need land-based aviation. All the land-based aircraft currently operated by the navy will be transferred to the air force. So, Mr. Lin, you There is no need to worry. Even if the Navy has a need for Y-20 in the future, it will spend money to purchase it and it will have to be transferred to the Air Force in the future."

Wu Shengli smiled happily. He could give all the reasons for such bullshit. Not to mention the air force, the naval officers present also didn't believe Qin Tao's painting. Will the Navy become an exclusively carrier-based aviation force? How many aircraft carriers does the navy have? Like the United States?

 Stop dreaming, everyone has never had such a sweet dream even when they were sleeping most soundly!

 This is simply impossible!

However, it is okay to use this reason to fool the Air Force. Looking at Mr. Lin's unhappy expression at this time, you can tell how unhappy he is.

Wu Shengli was very happy, his son-in-law is really good! The Air Force was speechless after being criticized twice. Hum, it is not that easy to defeat the Navy. If the Navy had money, it would still want to build two more anti-aircraft destroyers!

The Air Force thinks that the research and development cost of one billion is high. Do you know that for the Navy, this money is simply not enough to spend, and at most two destroyers will be spent.

"Speaking of our navy's transport aircraft, I think that after the carrier-based early warning aircraft matures, this platform can be used to develop the navy's dedicated carrier-based transport aircraft. Now, should we listen to the 603 Research Institute's carrier-based early warning aircraft platform? Project progress?" Qin Tao said: "This aircraft is still very unique. If the Air Force wants to order it, it can. Navy leaders, let's not ask the Air Force for research and development funding. What do you think?"

“That’s right, our navy is very powerful, but we can’t hold back the ropes.” Leader Wu’s words did not make Mr. Lin vomit blood.

There is also precedent for the land-based use of naval carrier-based aircraft.

The U.S. Navy's Tomcat fighter jets and Hornet fighter jets are exported to the air forces of other countries. As for the U.S. Navy's E-2 early warning aircraft, it is purchased by the air forces of some countries. After all, the E-3 is too expensive.

Now, if the Navy wants to develop a carrier-based fixed-wing early warning aircraft, it will definitely have to invest a lot of money. Once it is developed, if the Air Force wants it, it can order it directly. We don’t need any R&D funds.

This sentence was so lethal that Mr. Lin immediately blushed.

Qin Tao is not afraid of offending Mr. Lin. After all, these are work matters. In private, we are still good friends. At worst, tonight, he will serve a drink to treat Mr. Lin to a meal. After drinking a bottle of Maotai, Mr. Lin will be angry. Disappeared.

“Then Mr. Chen, please introduce the body of the early warning aircraft.” Leader Wu continued.

Mr. Chen nodded: "Okay, then I will introduce the airframe. In this regard, we still have to thank Mr. Qin for allowing us to obtain the Yak-44 airframe platform. We decided to start from this airframe platform and integrate our Yunqi, Develop a dedicated carrier-based airframe..."

When talking about this, Mr. Chen suddenly thought of something: "We originally called this aircraft JZY-01 verification aircraft, but Mr. Qin is quite good at naming it. Do you want to give our early warning aircraft a new name?" ?”

Qin Tao smiled and shook his head: "Forget it, I don't know everything! You can choose the name later, but let's introduce the content first."

Mr. Chen nodded: "Okay, let's introduce the progress of this aircraft. Since the size is similar to our Yun-7, our original surveying and mapping team to imitate the Yun-7 will take over. This aircraft must adapt to the needs of carriers. Therefore, all aspects need to be strengthened. Fortunately, we have already developed carrier-based fighter jets in our country. We can use them as doctrine and directly use those from our brother units. Especially the nose landing gear. According to the original plan, this aircraft will eject and take off. Therefore, the nose landing gear also needs to be strengthened.”

"In order to adapt to our catapult, the total weight of this aircraft will be limited to 30 tons. If possible, 26 or 7 tons would be better. Of course, this depends on the weight of the early warning radar, but , we will try our best to ensure that this aircraft has a maximum weight of more than 35 tons, so that if the radar is overweight, it can still complete takeoff and landing."

The U.S. E-2 early warning aircraft has a maximum take-off weight of only about 24 tons. It was later enlarged to 26 tons. However, the Yak-44 became a 40-ton monster. This is of course because of Lao Maozi’s backward electronic technology.

 What about our own side?

We have just started, and no one knows what results we can develop. Therefore, the development unit of the airframe must be flexible.

If the radar is powerful, it is best to have a total weight of less than 30 tons. The lighter the radar, the more payload the aircraft has to carry fuel. If the radar is not powerful, then they have to allow the aircraft to complete the carrier-based takeoff and landing. .

This flexible strategy won unanimous approval from everyone present. Especially Mr. Wang, the development of the carrier-based early warning aircraft radar has not yet begun. They have to put all their efforts on the Air Police-2000 project, and the development of the airframe must also be advanced. Now, 603 has given them such a large redundancy. It really moved them.

Regarding the research and development of this early warning aircraft, Mr. Chen introduced it for more than half an hour. Anyway, this project is only in the startup stage for the time being. There is no detailed information yet, it is just analysis.

 At the end of the day, Mr. Chen still mentioned R&D funding.

"Since the development of this carrier-based early warning aircraft is very difficult, we also hope that the Navy can provide us with enough funds." Chen said: "If the Navy can first provide us with 200 million, then this project can be officially unfolded.”

The Navy cannot turn down this money. Wu Shengli nodded: "Of course, no problem. We will apply for special funds from our superiors. If our superiors do not approve it, our Navy will have to tighten our belts and complete the research and development of this project. After all, Our aircraft carrier project has already started, and these technologies are about to achieve breakthroughs."

The events of last year have greatly stimulated the superiors, and the power of the aircraft carrier has also been demonstrated. Therefore, those who doubted the aircraft carrier no longer objected, and the aircraft carrier project must be launched.

Relevant subsystems also need to be launched, including catapults and early warning aircraft. The early warning aircraft project for helicopter platforms has been launched, but those are only for emergency use. Fixed-wing early warning aircraft are the most important.

You have to tighten your belt!

"As for the ejection weight of this aircraft, we still have to ask the catapult R&D unit. If the power of the catapult is strong enough, it should be able to eject a heavy enough early warning aircraft." After Wu Shengli finished speaking, he looked at his watch: " We’ll end the morning meeting here, let’s go have dinner first, and we’ll discuss the topic of catapults in the afternoon!”

 It’s already noon, everyone is hungry, and the catapult has nothing to do with the air force, so Mr. Lin and the others can leave first after eating! So, it’s time to eat this meal.

 Huanglou has a special canteen. Today, we specially prepared lunch for guests. You can smell the fragrant aroma from a distance.

Mr. Lin's face looked a little ugly: "Everyone, listen up, open your stomach and let me eat!"

"Eat, we've taken care of it! If you can't walk anymore after eating, we'll find someone to carry you back!" Wu Shengli was also very generous. Of course he knew that Mr. Lin was still annoyed about the sharing of R&D funds. But the navy has taken advantage, and now it doesn't care so much. Can the navy be starved for food? Open to eat!

 “Why is there no wine? Give us Maotai!” Sitting at the table, Mr. Lin continued to find fault.

Wu Shengli smiled and waved with satisfaction: "Okay, let's go to Moutai! If you don't need to attend a meeting in the afternoon, you can drink freely!"

“Lao Wu, this is what you said!” Mr. Lin said with a smile: “Give us twenty bottles first!”

These days, an ordinary Maotai bottle costs 200 yuan, and if you buy 20 bottles, that’s 4,000 yuan!

 Mr. Lin decided to have a serious meal.

Wu Shengli nodded: "Okay, sure! As long as you can drink it, it's fine. I have to say something ugly first. When the time comes, you will have to drink it even if you can't finish it!"

 After saying this, Wu Shengli checked the air force personnel again, and found that there was no thin telephone pole among them, and then he breathed a sigh of relief.

“Hmph, if we can’t finish the drink, let’s pack it up and take it away! We just have to eat and take it!” Mr. Lin also started to cheat.

Since the two gods were fighting, it was inconvenient for others to get involved. Qin Tao had already sat down and picked up the chopsticks.

This table full of food is so delicious, it’s almost like a New Year’s Eve dinner!

“Hey, Taozi, you’ve already eaten. Why don’t I have a son-in-law like you?” Mr. Lin sat next to Qin Tao: “Come on, you have to have a drink with me.”

“Mr. Lin, I have a meeting in the afternoon, so I won’t drink at noon.” Qin Tao said, “Would you like to wait until the evening and I’ll have a drink with you?”

“It’s not like I don’t know your kid’s drinking capacity. Even if you drink a bottle of wine, you can go to a meeting without being affected. Today at noon, you must drink with me!”

Qin Tao was a little helpless: "Mr. Lin, if you weren't so willful, we could talk about something while eating, such as the next development route of the Air Force."

Mr. Lin thought for a moment, then nodded: "Okay, then I will listen. What suggestions do you have for our Air Force?"

Qin Tao is the best at this: "First of all, from a guiding ideology, our air force must develop from a defensive air force such as homeland air defense to a combined offensive and defensive air force. After all, offense is the best defense!"

Mr. Lin nodded: "Yes, you are right! This thinking has begun to develop in our Air Force. Everyone is thinking about the future development direction of the Air Force. It is indeed both offensive and defensive."

"Since it is both offensive and defensive, a large number of long-range fighter bombers are needed." Qin Tao continued: "Now, Lao Maozi has developed a two-seat fighter bomber based on the Su-27 trainer aircraft. Our Air Force also needs This kind of aircraft."

Wu Shengli smiled secretly in his heart, this is also an aircraft that the navy urgently needs! The Navy has already evaluated that if it also equips the Su-27 series aircraft, it will definitely not need a single-seat, but a two-seat fighter-bomber!

Now, the Navy can once again take advantage of the Air Force’s research and development funds!

PS: There is no technical information on what band the Air Police 600 radar uses. There is only a radar called the "Silk Road Eye" KLC-7, which uses the same system as the E-2 and has to rotate the radome, but This product is for foreign trade, I don’t know if it is the same for personal use. If the reader knows, you can send it to the Hero of East China, and we will correct it later. Just think of it as the twists and turns in the development of carrier-based early warning aircraft. There is also information that it is because the weight of the active phased array plate is too large, and the engine power of our early warning aircraft insufficient. However, in the book, we have already used Lao Maozi’s turboprop engine, and its power output is much stronger than our turboprop-6C. Therefore, if it is powerful enough to fly bricks, the early warning aircraft in our book may be able to carry out phase control. As for the array radar, let’s assume for the moment that it has the same band as the Air Police 2000. I also checked the Yak-44 early warning aircraft, and it was said to be B-band. The East China Hero did not graduate from elementary school and did not know which band B-band was.
