Lin Hongfei continued, "According to my calculations, if the wingspan of the aircraft can reach about 25 meters, the flight altitude can be maintained at 7,500 meters to 8,000 meters; The diameter of the radar radome of the latest model of the U.S. military's E-2C carrier-based radar early warning aircraft is 7.3 meters, if we take the Eurocopter EH101 as a reference object to design this aircraft, the gap between the main track and the front and rear tracks of the EH101 can accommodate a radar radome with a diameter of 7.7 meters at most, through the adjustment of the main landing gear and the front and rear landing gear, or it can also accommodate a radar with a larger diameter; if the Mi-26 is taken as the reference object, A radome with a diameter of about 10 meters can be arranged. ”

"Compared with the British 'Sea King' carrier-based early warning helicopter and the former Soviet Union's KA-31 carrier-based early warning helicopter radar layout scheme, we can deploy a larger radar, to achieve a longer detection distance and more powerful data processing capabilities, just considering this special way of lower radar radome, such a large radar radome, even if our radar detection technology is backward, can make up for the lack of power, the radar accommodated is enough to meet the aircraft carrier as the center, Early warning of low-flying fighters within a minimum of 800 km is required. ”

"My personal little suggestion: the distance from the belly to the lowest point of the radome should not exceed 1 meter, and the highest should not exceed 1.2 meters, in order to ensure that the structure is strong enough, the radar is best to use an active phased array radar that does not have to rotate, of course, whether it is a reference to EH101 or a reference to Mi-26, the landing gear in addition to ensuring that the belly has enough ground clearance, but also through a special heightening and reinforcement design, well, this is what I said, experts must be able to imagine. It's the kid who is unreasonable. ”

Speaking of this, Lin Hongfei took a breath and looked at the experts who were frowning and thinking about his diagram, and he was really relieved.

He can be sure that there must be some problems with his two-knife design aircraft, at least in Lin Hongfei's own opinion, the distance between the radome and the belly is a little too close, and such a close distance will inevitably produce some aerodynamic interference for the stable flight of the aircraft, but in Lin Hongfei's view, this should be the only large radar radome that the rotorcraft can use, and the layout scheme of "standing high and seeing far".

As for the problem of aerodynamic interference, there is no fear of problems. Just find a way to solve it, what he is most afraid of is that these experts directly deny this idea.

As soon as Lin Hongfei thought of this, Mr. Zhou Zhenguo, the chief designer of Yunqi, frowned and spoke, "If it is not more than one meter." So the length of the radome mount cannot exceed 55 cm at most? Such a large radome, such a close distance between the two. ...... that can cause serious aerodynamic interference to the flight of the aircraft"

Really! Mr. Zhou's answer confirmed Lin Hongfei's guess. Such a small distance between the radome and the belly of the aircraft can indeed cause serious interference.

"Old Zhou, is there a way to solve it?" Lin Hongfei hurriedly asked, at this moment, it was false to say that Lin Hongfei was not nervous, "I won't tell you, this is the only way that I can think of to install a large radar for an early warning aircraft without catapulting and taking off." The detection range of the KA-31 early warning helicopter is 115 km...... Boy, I really think that this thing can be used by a medium-sized mixed fleet, but when it is used as an early warning aircraft for aircraft carrier formations, this distance is really not enough. ”

As soon as Lin Hongfei said this, not only Lin Hongfei was eagerly waiting for Zhou Zhenguo's answer. Even several bureau standing committee members and military generals were looking at Zhou Zhenguo anxiously, but Lin Hongfei's nervous expression fell in the eyes of the bigwigs, and he couldn't help laughing: This kid ...... Are there times when you're scared?

Just think about it carefully, how old is Lin Hongfei, 24 years old, this kid is just a demon in the field of motorcycles and cars, if he is also evil in the field of aircraft, it really makes people wonder if this kid is really a demon, fortunately, although this kid is very demonic this time, but the degree of this demon is still within the acceptable range of everyone.

"Mr. Lin, rest assured, your plan is absolutely right in terms of the general direction, it is the only one that can be used on a fixed-wing early warning aircraft on a skid take-off aircraft carrier, and it is definitely the best plan we can achieve at present." Zhou Zhenguo comforted Lin Hongfei with a smile, and first calmed Lin Hongfei's mind.

In the opinion of Lin Hongfei, in the opinion of Zhou Zhenguo and other experts, the detection distance of the 115 kilometers of the KA-31 early warning helicopter is really not enough, at best, it can only be used for small area early warning for the small fleet, if there is a choice, it is absolutely not necessary to make do with the KA-31, Lin Hongfei's plan can actually arrange a radar larger than the radar of the US military's E-2C carrier-based early warning aircraft, which gave the generals a huge surprise!

Anyone with a little military knowledge knows that the size of the radar is directly equated with the detection capability, and under the premise that the electronic technology and radar technology of the Republic are not comparable to the Americans or even the Russians, in order to ensure the detection distance, making the radar larger has become the only choice.

But the large-size radar is easy to make, but it is difficult to install it on the plane.

When he said that if the Mi-26 fuselage scheme was adopted, it would even be permissible to arrange a 9.8-meter-diameter radome, if it were not for the presence of so many leaders, the admirals present would almost immediately want to force Lin Hongfei to adopt this plan: The radar diameter of the E-3 "Watchtower" early warning aircraft used by the United States for territorial air defense is only 9.1 meters. Even if our country's radar technology is backward, we are not compared with the largest 7.3-meter-diameter radar used by the E-2 now, and compared with the 4.11-meter-diameter radar of the earlier model, our 9.8-meter-diameter radar will not be closer to the detection range of the 4.11-meter-diameter radar of the old United States, right?

"Leaders, please wait a moment, we need to discuss this issue." After pondering for a while, Mr. Zhou Zhenguo did not answer immediately, but glanced at the experts present, and then said to the military generals and bureau standing committee members present.

"Okay." Today, I used my own actions to show my attitude: I want to know as soon as possible whether this kid is feasible or not.

……………………

With such attention nowadays, who would dare to slack off? A group of aviation experts immediately gathered together and discussed in a whisper, and it took more than half an hour for the preliminary discussion to reach a result. Zhou Zhenguo and Ouyang Shaoxiu said to the leaders and generals of the military, "Leaders, generals, we have discussed it, it is very difficult, but it is not impossible to solve. ”

"Shh......h

Zhou Zhenguo and Ouyang Shaoxiu's answer made everyone breathe a sigh of relief, including Lin Hongfei, he was really worried that he would get a "no way" answer, now it's okay, as long as it can be solved. As for the difficulty...... How can it be that there is no difficulty to highlight that we have overcome many difficulties and countless difficulties to complete this arduous task? If it's not too difficult, it doesn't show our efforts!

But Mr. Zhou Zhenguo continued, "When we discussed just now, we also noticed that this aircraft is a very potential platform, in addition to being able to be changed into a carrier-based early warning aircraft. It can also be converted into carrier-based transport aircraft and carrier-based air tankers. ”

"Carrier-based transport aircraft and carrier-based air tankers?" Lin Hongfei exclaimed.

"Yes, that's right. That is, carrier-based transport aircraft and carrier-based air tankers. Especially this carrier-based air tanker, I think this thing must be on our aircraft carrier, our country does not want the United States, the Americans' aircraft carrier formation is not equipped with carrier-based air tankers, that is because they have many overseas bases and air tankers stationed in overseas bases to support their operations, but our country obviously does not have such conditions and guarantees. In this way, carrier-based air tankers are of great significance to our aircraft carrier formations. ”

"If the aircraft is designed according to Comrade Lin Hongfei's previous proposal, it will have a load of 13 tons and a wingspan of about 25 meters, including its own fuel tank. It can achieve about 20 tons of refueling in the air, which is equivalent to filling up four fighters, carrier-based air tankers can wait at a distance of 100 kilometers from the aircraft carrier, and our fighters can take off with less fuel and full ammunition; In the same way, with this air tanker, it is equivalent to effectively extending the combat distance of aircraft carrier-based aircraft, which is of great significance to the entire aircraft carrier formation! ”

Lin Hongfei was shocked when he heard it! Carrier-based air tankers and carrier-based transport aircraft? That's right! Why didn't I think of these two uses?

An expert is an expert, and at this moment, Lin Hongfei was really convinced.

The admirals present nodded their heads again and again, and their faces turned red.

Think about it, if the Varyag is used as our country's first aircraft carrier, without a catapult, we can only take off with a full fuel and a light load, or half fuel and half a load of takeoff, but in any case, we can't take off with full fuel and bombs like the US aircraft carrier formation, but if there is an air tanker waiting in front of the aircraft carrier formation...... It's exciting to think about!

Therefore, we jointly suggested: Comrade Lin Hongfei's idea should be listed as a secret at the highest level of the state, and this project should be highly valued and listed as a military science and technology research project that the state has the highest priority for development and support. As for the military, whether it is to learn from the EH101 or the Mi-26, we hope that the military will also come up with a discussion result as soon as possible, and when discussing, it is best for the navy and the army to participate together, and make this project a project that can be used by the navy and the army, and the navy will set up a stall, and the army will set up a separate stall, which is too wasteful......"

It's just that this topic is a little sensitive, and Mr. Zhou Zhenguo only mentioned it slightly, and then pressed the topic and continued, "In addition, Comrade Lin Hongfei's design is a new technology after all, I suggest that the verification of related technology should start now, we think it is good to test it with the Zhijiu modification, as for some of the patent issues that may be involved in the EH101 helicopter or Mi-26 helicopter, hehe......"

Zhou Zhenguo smiled disappreciatively.

The leaders and experts present also laughed: If it was just an ordinary civil, it would be fine, but in the contest between countries, who will play "Song Xianggong" with you? We have a good relationship, maybe I may still spend money from you to introduce some skills, but if I can get your stuff without spending money, my brain is pumped or I have a lot of money? Do we do less of the "take it without telling us" thing? Is there still less time when "AIA is surprised"? But so what? Could it be that because of the surprise of our friends, we will not be able to live a long time? There is no reason for this!

"Good! That's it, Comrade Lin Hongfei, give you two years to use the straight 9 as a platform to do a feasibility test of modification, if it proves that this is indeed feasible, then officially launch this project! "As the leader of the party, government and army of the republic, I have officially made a decision today!

"Yes!" Lin Hongfei didn't dare to slack off, and immediately stood up and answered loudly.

"The second task is to find a way to bring in some of the engines you mentioned from Ukraine for the Mi-26...... Didn't you say it before, it doesn't matter if you don't need it now, seal it up, and you can use it in the future. ”

"Yes!" Lin Hongfei replied loudly, but hesitated slightly.

"Huh? Comrade Xiaolin, what can you say, this time you gave us such a big surprise, could it be that you are still ready to give us a surprise? "What kind of person is today? immediately noticed that Lin Hongfei seemed to have something to say, and immediately asked.

"It's not a surprise," Lin Hongfei smiled shyly, "That's right, the D-136 turboshaft engine used on the Mi-26 is derived from the D-36 turbofan engine we imported from the Zaporosh Progressive Machine-Building Bureau in Ukraine, and the core engines of these two engines are basically the same, so ......"

"So you're going to copy D-136?"

"Yes, we have the basic technical conditions, I think we can try to imitate D-136," Lin Hongfei nodded, and said boldly, "Even if we can't make the 8,500 kilowatt one that the former Soviet Union did, even if we can only make 6,000 kilowatts or even 5,000 kilowatts, it's our own thing,...... It's great that others use two engines, but we use three, although the endurance and economy are a little worse, but they will not be stuck at critical moments. ”

"What do you think?" Today, he turned his head to look at the Prime Minister on the side, and said with great interest.

"I think you can try, the little guy is right, even if we don't make it as good as the Ukrainians, and the performance is a little worse, but we won't be stuck at a critical moment, and the quality can't keep up for the time being, so we will make up for it! In the future, it will develop slowly, and it will always be possible to do better. The Prime Minister said. (To be continued......)
