The general direction was thus determined. Pen, fun, pavilion www. biquge。 info

Although everyone knows that a stealth aircraft is a good thing, and a stealth strategic bomber that can get the cooperation of synthetic aperture radar imaging satellites and early warning command aircraft is a good thing, everyone understands better that this thing is too unrealistic for the republic at this stage, just like Tang Changhong said, the meal must be eaten one bite at a time, but two points are clear: that is, it must first have a large range and a large bomb load......

According to our calculations, with the power level of NK-8-4, there is no big problem for the H-6 equipped with this engine to carry six, but I suggest that this opportunity be used to modify the aerodynamic shape of the H-6, especially the wing, anyway, after the NK-8-4 is replaced, the engine air inlet and air inlet will definitely have to be redesigned, and it is better to do the aerodynamic work at one time. It's just the start of the sixth master to re-optimize the styling......"

"When it comes to modifying the wing, I think we can take the supercritical airfoil used on the MPC-75 for reference, if the supercritical airfoil can be used, the lift of the sixth master can be increased by at least 15%."

"That supercritical wing on the MPC-75? Good idea, by the way, this supercritical wing technology can also be used for the H-8? ”

"Speaking of the H-8, the H-6 is too small to be equipped with a revolver-type missile launcher in the bomb bay, so the H-8 is always okay, right?"

"If you want to use the H-8, you must put on the revolver-type weapon rack, this thing is too convenient, the bomb bay can be equipped with different types of ammunition, different purposes, unlike the H-6 'grape' bomb bay, I want to use the third bomb, I must first throw out the first and second bombs, and the ammunition is placed in the bomb bay, which can also reduce the impact on aerodynamics......

"Engine! I remember that Chen Dong said that it is possible to develop an improved NK-8 with a bypass ratio of 2 and a maximum thrust of more than 130KN? If four NK-8s of this improved version are used, there is no problem with a maximum bomb load of 25 tons, right? ”

"Speaking of which, can we develop another type of air tanker on the basis of this bomber?"

As soon as this voice came out, there was an instant silence in the conference room, which was still noisy like a vegetable market just now.

Chen Geng and Mao Donghai, who were quietly discussing these two aircraft, also pricked up their ears at once: Develop a type of air tanker based on the H-8 equipped with four engines?

As early as 1988, the chief designer put forward the requirement of developing our own air refueling aircraft, and now the air refueling aircraft and the corresponding refueling technology have entered the final stage of tackling tough problems, and if everything goes well, it is expected that by the end of this year, China will be able to develop our own air refueling capability on the basis of the H-6.

Of course, the H-6 based on the H-6 is inseparable from the cooperation of the Westward Flight, and Mao Donghai is well aware of the key performance of the H-6: Within a radius of 1,000 km, the H-6 can carry 37 tons of fuel, and in addition to its own use, it can also provide 18.2 tons of fuel to the fighters, that is, to provide the six Jian-8s with fuel in the air.

After simple calculations, it can be concluded that if the H-8 is really a strategic bomber with a range of 11,000 km and a maximum bomb load of 22 to 25 tons, then even the most conservative estimate is that within a radius of 1,000 km, the H-8 can provide at least 50 tons of fuel to combat aircraft. With a refueling capacity of more than 50 tons, it will become the world's third largest air tanker slightly lower than the Soviet Union's Il-78 and the US military's KC-10, and its air refueling capability is more powerful than that of the US military's current KC-135, KC-130, and Britain's VC-10.

"Chen Dong, what do you think?" Mao Donghai was suddenly excited: "Do you think there is a head?" ”

Chen Geng thought for a while, and did not answer directly, but asked first: "The bombardment of oil-6 is almost complete, right?" ”

Mao Donghai hesitated for a moment and nodded: "It's almost done." ”

Chen Geng asked again: "I heard that the equipment for refueling in the air on the bomber-6 and Jian-8 was provided by the British?" Have we mastered these technologies? Will it be possible to produce it itself and transplant it to a new aircraft in the future? ”

"Absolutely!" Mao Donghai nodded, his tone was very affirmative.

"That's definitely no problem technically, but I'm thinking about another problem," Chen Geng said: "Now the large air tankers in the world are either modified from military transport aircraft, or simply directly modified civil aircraft, and we are the only ones who use bombers to modify air tankers, and bombers are much more expensive than civilian aircraft......

"I know," Mao Donghai said this, Mao Donghai's mouth was also a little bitter: "But there is no way, our country's fighter planes are all low-speed aircraft with poor performance and high speed, whether it is the Y-7 or Y-8, it is not suitable, and the only platform that can be used for modification is the H-6, and there is no way to be expensive, it is better than not having to use it." ”

Chen Geng: "That's what I think, after we have completely mastered the technology of refueling and receiving fuel in the air, if the H-8 can be put into production, it is not impossible to modify a few planes in small batches, but we can completely develop a type of air tanker on the basis of the MPC-75." ”

"Modified MPC-75?" Mao Donghai felt that Chen Geng's brain hole was a little too big: "Can this plane work?" ”

"Why not?" Chen Geng asked rhetorically: "The maximum commercial load of MPC-75-100 is 9 tons, the maximum commercial load of MPC-75-200 is 12 tons, and the future MPC-75-300 can even reach the maximum commercial load of 16 tons.

What is the maximum bomb load of the H-6? 9 tons; What is the fuel consumption rate of the turbojet-8? More than 1.3; even so, within a radius of 1,000 km, the H-6 modified from the H-6 can provide 18.3 tons of fuel. What if the MPC-75-100 was replaced with a turbofan engine with less dead weight and low fuel consumption? Even according to the most conservative estimates, within a radius of 1,000 kilometers, an air tanker converted from the MPC-75-100 cargo type can provide at least 25 tons of aviation fuel, and if it is an MPC-75-200, it can properly reach 30 tons.

If every air refueling brigade in our country is based on four or five bomber-8 aircraft with a large fuel load as the core, supplemented by about 10 MPC-75 air tankers......"

"Wow!" Mao Donghai's eyes lit up all of a sudden!

On weekdays or when the combat mission is not very urgent, the MPC-75 air tanker with a relatively long airframe life and low cost of use is dispatched, and in the event of an emergency or when it is necessary to refuel a large group of aircraft with a long-range attack, the bomber-8 with a larger fuel load and a longer range is used to cooperate with each other, and the Americans also cooperate with various air tankers with different fuel loads, such as the KC-10, KC-130, and KC-135.

Even if we take a step back and the H-8 cannot be put into use in the short term, the MPC-75 air tanker can withstand it for a while, at least this cargo is much stronger than the H-6 modified on the basis of the Sixth Master, right?

Thinking of this, Mao Donghai nodded and said in a low voice: "Okay, just do it!" ”

After speaking, Mao Donghai coughed lightly: "It's time for discussion, Runhua Industry calls this kind of discussion activity brainstorming, so everyone can use their brains to think, don't be afraid to say something wrong, I'm afraid that everyone won't dare to think about it." ”

This can be regarded as defining the words of the old brother who has just proposed the use of the H-8 modified air tanker: Do not be convicted for your words, and everyone can speak their minds freely. Now that Mao Donghai has set the tone, all kinds of ideas have come to mind for a while: to use the H-8 to modify an electronic reconnaissance plane, to use the H-8 to modify an antisubmarine patrol plane, and to use the H-8 to modify a communication relay for communication with nuclear submarines...... There was even an old man who proposed to use the H-8 to modify the airborne early warning plane......

Hearing these thoughts, Chen Geng couldn't help but laugh: Brothers, are you not a special aircraft that doesn't know the price of firewood and rice, and the purchase price is much more expensive than the MPC-75 with a bare machine? Whether it is an electronic reconnaissance plane, an antisubmarine patrol plane, or an airborne early warning command plane, this is all a job that the MPC-75 can handle.

Looking at Chen Geng's expression, Mao Donghai still felt strange in his heart, what you said to let everyone speak freely was what you said, why are you so bitter and hateful now? Whether you are doing your old job: a bomber, an electronic reconnaissance plane, an anti-submarine patrol plane, or an air early warning command plane, the H-8 platform can be used, what do you mean by the expression that someone owes you a lot of money?

When he figured out what Chen Geng was thinking, his face suddenly became really feverish: Also, since there is a lower cost of procurement and use, and more importantly, the MPC-75 can be put into use in four or five years at most, why is it that he does not know when the H-8 will be officially installed?

Mao Donghai, who couldn't hold his face a little, coughed lightly: "Ahem...... However, when we discuss, we should also pay attention to the actual situation in our country, for example, the two proposals of using the H-8 to modify an electronic reconnaissance and an anti-submarine patrol plane, and our MPC-75 will be able to do this work; if we are worried that the range will not be enough, the great thing is to install a set of air refueling system for the military version of the MPC-75, so why should we be thinking about the H-8 no matter what the work is? How expensive is this product? Remember, don't use a slaughtering knife to kill a chicken. ”

――――――――――――――――――――

The designers and engineers of Xifei were unreliable when their brains were opened, and even occasionally their brains broke through the sky, but after a few days of brainstorming, Chen Geng also benefited a lot, and even put forward a lot of useful suggestions for MPC-75, which was not the theme of this brainstorming.

But after a few days, Chen Geng also had to go back, in the face of Mao Donghai's retention, Chen Geng said: "Mr. Mao, I also want to stay for a few more days, but no, the little devil is here, I have to rush back." ”

"You're talking about a partnership between your company and Yamaha?" Mao Donghai really knew about this, smacked his lips, and said with some regret: "Then you have to go back...... Come on, brother, when are you leaving, I'll send you. ”

"What are you going," Chen Geng waved his hand: "I heard that your benefits for Xifei during the Chinese New Year this year are quite good?" Get me a car, I'll take it. ”

"Get out!" Mao Donghai unceremoniously raised a middle finger to Chen Geng: "The welfare of your Runhua Industry is much better than that of our Xifei, it's good that I didn't ask you, you kid actually beat my idea?" Get out of here! ”

Chen Genghui slapped his middle finger and laughed!

……………………

"Chen Geng, where are you now?" Chen Geng, who had just arrived at the airport, received a call from Ding Ruoyan.

"What about Chang'an, how?"

"Let me tell you the news, Argentina is going to build a car factory, and they seem to be planning to attract investment on a global scale, do you have any ideas?"

"Really?" Chen Gengmeng shook his head and hurriedly said, "Interested, of course interested, you tell me in detail, what is going on?" ”

Ding Ruoyan said: "I don't know very well, roughly Argentina intends to revitalize its own national automobile industry, create its own national automobile brand, this time the plan to engage in this automobile factory is Argentina's independent capital based on the project, I estimate that it is an Argentine foreign technical cooperation project, detailed information I am asking someone to collect, it is estimated that there will be news soon, I just tell you first, you have a good psychological preparation here." ”

"Great!" Chen Geng slapped his thigh excitedly: "My dear, thank you for the news, you have helped me a lot!" ”

He roughly guessed what was going on, nine times out of ten, it was the same as the Hongqi Mingshi sedan with the Hongqi logo on the FAW, which was actually the Audi 100, except for changing the standard, the others were someone else's, but this is not important, the important thing is that if you can win this project, Runhua Industry will have a base in South America, which is too critical for Runhua Industry to develop the South American market in the future.

PS: Brothers, it's still a 4000-word chapter.

Send this PS is mainly to say two things to the brothers.,One is the problem of paying back.,I owe you 7 chapters last month.,The original idea of the millennium was to repay the debt in the form of a plus.,But now it seems a little too much.,Then let's change the way.,Then write 1000 more words per chapter to repay the account.,This month is 31 days.,The minimum guarantee is 186,000 words.,Counting the 21,000 words of the repayment.,The minimum is 210,000 words.,The extra is more.,At the end of the month, let's see the total update volume to know if the account has been paid.,Right?

The second, originally said that the public account would be opened around the 10th, but the millennium has not been too clear in the past few days, so it needs to be postponed for a few days, and I ask the brothers not to fight, hugging the head of the rat......
