"There is no problem in replacing the engine for the H-6, although I have not seen the NK-8, but through the NK-8 information sent by Runhua Industry, I think it is not very difficult to replace the NK-8 for the H-6," Xu Deguang pushed his glasses, and as the deputy chief engineer of Xifei, he said with confidence: "But the question now is, what kind of H-6 does the navy plan to have?" Is it just a simple engine change, or is it a large-scale upgrade along with the avionics system, flight control system, aerodynamics, etc.? What do you want to achieve after upgrading? And what are the operational requirements? ”

Spreading his hands, Xu Deguang said helplessly: "Now your navy just said that it wants to reissue the H-6, but there are no specific requirements, so how can we make a plan for flying west?" ”

Chen Geng was immediately embarrassed, and he immediately turned his head to look at Liang Dingguo. Pen, fun, and www.biquge.info

Liang Dingguo is even more embarrassed: he is the military representative of the navy, which is true, but the problem is that no one has communicated with him before.

Looking at Chen Geng and Liang Dingguo, who looked embarrassed, an extremely bad feeling rose from Mao Donghai's heart, he endured it, and finally couldn't hold back: "Chen Dong, you haven't communicated with the navy about these problems before, right?" ”

“……”

Chen Geng was suddenly embarrassed, how could he answer this? Did you tell Mao Donghai that he had only communicated with Chief Li Jianguo before, and the specific details had not yet been discussed?

However, Xu Deguang's words were not finished, and before Chen Geng could speak, he continued: "By the way, there is another question, compared with the turbojet-8, the air intake volume of NK-8 is larger, and it is still unclear how much adjustment needs to be made to the overall aerodynamic layout of the H-6, but the air intake and tail nozzle and the fuselage in this position must be re-aerodynamically repaired, and from my personal experience, because the thrust of the engine has increased a lot, and the output characteristics have also changed greatly, the main wing and tail wing must also be adjusted. In order to adapt to the impact of increased air intake and thrust on the fuselage.

Of course, the thrust has increased so much, not to mention anything else, the weapon system, especially the fire control system, will definitely have to be updated, and I don't think I dare to say anything else, but the increase in the number of external weapon pylons from the current H-6D to 4 to 6 should not be too much of a problem, which means that it can carry up to 6 YJ-6 air-launched anti-ship missiles.

If we just do this, without updating avionics and other systems, I estimate that the cost will start at least 50 million, and maybe more......"

Xu Deguang's implication, your navy's life is sad enough now, can you get so much money? For Xifei, it is definitely impossible for them to contribute this money, because this project is not a national project, and Xifei can help the Navy carry out this project, but the corresponding funds will definitely need to be provided by the Navy.

Liang Dingguo was a little gloomy: at least 50 million R&D funds, which is too much, you know, this does not include the later modification funds.

But Chen Geng, who originally thought that he would need at least more than a billion yuan, suddenly breathed a sigh of relief in his heart: only more than 50 million is enough? I thought it would take at least seven or eight hundred million.

"I will communicate with the relevant heads of the navy after I go back on the specific plan and funding," Chen Geng pondered for a moment, then raised his head and asked Mao Donghai: "But can I ask, just take the plan of replacing the engine, updating the fire control system and fine-tuning the aerodynamic structure, under the premise of ensuring capital investment, how long will it take to come up with the first aircraft?" ”

Xu Deguang did not hesitate to say: "If the research and development funds can be guaranteed, two and a half years, at most three years, the first aircraft will definitely be able to go to the sky." ”

2 to 3 years? At this point in time, it is very good, it should be not long after the first batch of NK-8 engines assembled by Runhua Industry came off the assembly line, Chen Geng nodded: "Very good, I know, I will communicate with the relevant leaders as soon as possible." ”

None of the comrades in Xifei were surprised that any change in weapons and equipment was carried out with great caution in the early stage of the demonstration, not to mention that it could not be finalized in one or two years, and even if it was demonstrated for three or five years, it was not unusual, not to mention the H-6, the only large military combat aircraft that China could produce -- even if it was just the simplest engine change, the entire flight envelope of the aircraft would have to be flown out again, and the amount of work was very large.

Everyone thought that this meeting would be over here, but Chen Geng's next sentence stunned Xifei and all the comrades in the military......

"Mr. Mao, I heard that our Xifei once had a H-8 program equipped with four engines, and the H-6I can be regarded as a technical verification machine for the H-8, and the H-8 can also be regarded as an oversized H-6, is this really the case?"

Mao Donghai hesitated, but nodded: "That's the case." ”

Anyway, the H-8 itself is a project that has been discontinued, and the level of secrecy is not very high, so there is no problem with Chen Geng's secrecy level, and it doesn't hurt to give him a brief explanation.

"Oh?" Chen Geng seemed to be more and more interested in this, raised his eyebrows, and asked curiously: "I went to see the H-6I two days ago, and I have to say that I was very shocked, it is a pity that such a project was stopped...... Can I ask us about the general situation of the H-8 and where the original H-8 plan has gone? ”

Mao Donghai groaned, hesitating, not knowing whether to say or not, first of all, although the H-8 bomber project was discontinued, after all, this was a strategic-level project carried out by the state before, and even if it was discontinued, there would be a certain level of secrecy; The second and most important reason is what he plans to do?

I have to say that in the hearts of people in this era, the string of "secrecy" has always been very tight.

"Mr. Mao, I just want to know some general information, such as bomb load, empty weight, maximum take-off weight, range, etc., even if I know this, it shouldn't cause any harm to the country, right?" Chen Geng asked with a smile.

Also!

Chen Geng's words reminded Mao Donghai, not to mention Chen Geng's secrecy level, after all, the H-8 is a project that has not even started to prepare materials, let alone a prototype, and can be regarded as a completely non-existent project, even if he tells Chen Geng some basic data, what can he do? Not to mention that Xifei and Runhua Industry are still cooperative partners, and in the future, they will rely on Runhua Industry's NK-8 engine to convert it into a military aircraft on the basis of MPC-75.

Thinking of this, Mao Donghai no longer hesitated, and laughed: "Wherever Dong Chen says, it's all things that stay on paper, what can't be said?" After a brief pause, Mao Donghai said: "The empty weight of the H-8 is 65 tons, the normal take-off weight is 155 tons, the maximum take-off weight is 163 tons, the normal bomb load is 7 tons, the maximum bomb load is 18 tons, and it has a maximum range of 11,000 kilometers while carrying 7 tons of weapons. ”

"The technical demonstration has been completed, and the scheme is close to finalization?" Chen Geng was shocked: This "big H-6" has actually come to this point? After a moment of silence, Chen Geng said in a low tone: "It's a pity that this project didn't go ahead." ”

The normal bomb-carrying range of 11,000 kilometers is enough for this H-8 to take off from its base in China and carry out strategic nuclear strikes against the main political, military, and economic targets of the two superpowers, the United States and the Soviet Union.

"It's a pity," Mao Donghai sighed: "But there's no way, we don't have a suitable engine at all, the original idea was to buy JT3D from the United States, but how is this possible?" Without the right engine, this project simply wouldn't have been ......"

Speaking of this, Mao Donghai was suddenly stunned: The H-8 project was stopped, except that Xifei, as a state-owned enterprise, has no autonomy in funding for this project, and everything depends on state appropriations, and the other main reason is that there is no suitable engine, but now that this problem has been solved, Runhua Industry has obtained the NK-8 high-thrust turbofan engine from the Soviet Union, compared with the JT3D engine with a maximum thrust of 1,850 kg to be used in the H-8 project, the first batch of NK-8 produced by Runhua Industry The maximum thrust of the 4 engines is as high as 11,000 kg, and the fuel consumption rate of the two is basically the same......

Thinking of this, the idea in his heart that he had just shown a little sign and was pressed back could no longer be controlled and helped, Mao Donghai covered his chest and gasped: "Chen Dong...... Dude, what do you mean......"

Chen Geng nodded: "I think that after solving the engine problem, the H-8 project still has a lot to ......."

"It can't be!"

Before Mao Donghai could speak, Xu Deguang, deputy chief engineer, shouted: "If you restart the H-8 and come up with a prototype, without 6 years and at least 600 million yuan of investment, don't even think about it, Xifei will come up with such a large amount of money!" Wait for the prototype to come out. The investment after that is even more a bottomless pit! The whole project doesn't have 20 billion, don't even think about it! ”

"6 years and 600 million, right? Isn't it 100 million a year, no problem! Xifei can't take out such a sum of money, Runhua Industry can take it! Chen Geng slapped the chair hard, finally revealing his ambition.
