The Military-industrial Scientific Research System of the Academic Master Chapter 240

Chapter 240: Aircraft modification is also difficult (Part 1)

Not all the participants were qualified to follow the two leaders all the way, so when Chang Haonan and the others were led to the banquet hall by the staff, the vast majority of people had been waiting here for a while.

Several comrades belonging to the navy and air force quickly found their comrades, leaving only the scientific research people on Chang Haonan's side gathered together in twos and threes.

 At this time, there was still some time before the banquet officially started, so everyone was not in a hurry to take a seat.

“Speaking of which, Mr. Yan, did 701 mention other design elements of the new frigate?”

Chang Haonan is quite interested in this model, which he already knows will be typed as 054 and become the new generation of main battleship of the People's Navy.

 The main reason is that it will be very different from the 054 and 054A in the previous life.

“Well, Deputy Chief Engineer Lin did say that, but I don't know much about ship design, so I only heard a general outline except for the parts related to the power system.”

Yan Zhongcheng stretched out his hand to straighten his hair, and showed a slightly stiff smile:

"The plan of Institute 701 is to have a displacement of 4,500 tons and a long forecastle deck. The first three ships will directly use the 6-seat 8-unit 3K95 short-range air defense system imported from the Antai Scientific Research and Production Complex. It is said that it is being developed with the Army. The purchased 9K331 field air defense system has the same origin, which will reduce the pressure on ammunition production units after the introduction of production lines or imitation in the future.”

 Obviously, after seeing the true hero of the short-range air defense system, the Doyle M1, both the army and the navy no longer look down on the Red Flag 7, which is copied from the Sea Sidewinder.

 The corresponding localization process will obviously start earlier than in previous generations.

 This is of course a good thing.

 At least the big brother of the army, which is under heavy air defense pressure, does not need to wait until 2013 to finally start equipping the Hongqi 17.

Of course, whether Big Brother has enough funds to buy it is another matter.

The navy can also obtain the derived Haihongqi 17, which provides a solid final barrier for various ships and builds an ecological niche similar to the vertical ESSM in advance.

It's just that the curious revolver hanger on the 3K95 still needs to be removed and replaced with the same 8-gun launch box of the same model as the Land-based Doyle.

However, Chang Haonan was still a little surprised by this uncoordinated configuration:

 “With 48 rounds of ammunition, that's so much?”

Although the performance of the 3K95 system is much better than the Sea Sidewinder/Haihongqi 7 installed on the 052 destroyer, the 9M331 missile it is adapted to is a short-range point air defense system with a range and firing height of only 12km and 6km respectively.

Different from the more regional air defense missiles that are better, this last shield, which can only protect itself but cannot hold an umbrella, seems to have no need to pack in as many as 48 rounds.

What kind of scene is this? Can the terminal interceptor fire so many rounds?

  It is impossible to send just one frigate to such a big scene.

Of course, if the British saw this configuration, they would definitely cry with envy.

As long as there are several sets of similar things, it will not be possible for people to sink and damage so many ships on the Falklands.

“According to Deputy Chief Engineer Lin, this new model of ship has reserved room for modifications for future upgrades. For example, there is enough space on the front deck and inside the hull to accommodate 3S90M with a depth of no more than 5800 mm or similar performance. The vertical launch system is equipped with a total of 6 channels of anti-aircraft missile illuminators on the ship, so several more launch devices were designed.”

 At this point, Yan Zhongcheng paused, gently touched his temples, and after thinking for a moment, he continued:

"Although this is what he said publicly, I personally feel that these explanations are far-fetched. Our aviation system sometimes does things like leaving space margins, but if that is the case, there is no need to fill all these places. "

"The real reason may be that the frigate they built is indeed a bit big. Its full load displacement and hull size are similar to the 052 destroyer that just entered service. If there is no way to increase the utilization rate of the hull, it proves that it is necessary to design such a The large hull space may cause some resistance.”

After hearing this speculation, Chang Haonan immediately remembered a program he had seen on TV in his previous life.

A well-known military commentator said that in the 1980s and 1990s, there was indeed a force that purposefully obstructed the development of naval equipment in the name of excessive investment and impacting the economy. Now it seems that it is not just a matter of speculation. .

In today's timeline, due to the smooth finalization of the turbojet 14, Shipbuilding Industry Group, which is more confident in marine power, is also more radical in the design of new frigates. According to Yan Zhongcheng's description, it should be a relatively A model with better foundation and greater potential than the previous 054/054A.

 Of course the resistance will be greater.

After all, in the eyes of some people right now, your Chinese navy is actually preparing to equip a model with performance and size that is better than similar ships of the US military in one step. Even if it is just a less eye-catching frigate, it is a "treason" and transgression. Behavior.

"Hmm... As you said, it is indeed possible. Fortunately, the two major components of power and ship power should be able to use domestically produced subsystems, so that the actual cost can be reduced a lot, and the opposition will be weaker. "

Yan Zhongcheng glanced at Chang Haonan in surprise:

"When Deputy General Lin talked about this matter with me, he said almost exactly the same thing as you. But what he meant was to allocate part of the foreign exchange quota that was originally expected to import key parts of diesel engines to enhance the anti-submarine system, otherwise it would be a waste of full-fuel power. High speed and quietness.”

Yes, it seems that he is indeed going to benchmark and surpass Perry in all aspects.

 After briefly learning some information about the new frigate, Chang Haonan brought the topic back to Yan Zhongcheng's old profession:

"The 701 Institute has such a bold idea and wants a little bit of every function. The power requirements for us are quite high." "It is indeed not low, but according to Xiao Chang's previous communication with Shipbuilding Industry, we have already come up with a Remove the exhaust nozzle, use the dual-rotor structure as the gas generator of the gas turbine, and then equip them with a simplified design of the power turbine for technical verification. Factory 410 will start producing prototypes soon, no surprises If it can be delivered in mid-June of this year, let them start the ground test first, which will also increase their confidence in us. "

Yan Zhongcheng nodded, then raised his hand to check the time:

“Let's go, find our place first, and then we can chat slowly after we sit down.”

Naturally, the formal banquet at Sanzuomen cannot be in the form of a buffet like the previous ones that Chang Haonan has attended. They are all served at separate tables and according to the menu. High-end is indeed higher-end, but it is not. It's too convenient to talk about things.

Of course, the original intention of holding a celebration banquet is not just to let you talk about things...

Chang Haonan and Yan Zhongcheng are still old acquaintances in the aviation industry.

In addition, there is Du Miao Xu Yang from the Institute of Computing Technology.

 A group of people sat down according to the name tags placed on the table.

“Mr. Yan, now that the turbojet 14 has been finalized, do you have any ideas about taking over the Taihang project next?”

The person speaking was Luo Yang, who is currently in charge of the overall project No. 11.

 This person's name is naturally very familiar to the reborn Chang Haonan.

In the last life, after the ship successfully completed China's first aircraft carrier-based aircraft landing mission and returned to port, Luo Yang, the commander-in-chief of the J-15 development site, died in the line of duty due to sudden acute myocardial infarction and sudden cardiac death.

Of course, in 1997, he is still at his most youthful and powerful:

"According to the agreement, Project 11 does not include the matching AL31F engine. We are thinking that since this aircraft will become our own J-11 in the future, it will not be a problem to import aviation engines from the Russians, including I think the situation on Project 10 should be similar. It would be best to switch to domestic power at the same time as the J-8C, so that we can make some targeted improvements to the aircraft."

For Luo Yang, who is responsible for the overall project, it is of course best to complete these things in one step to save having to do it twice in the future, so he is very concerned about the progress of the domestically produced third-generation turbofan 10.

But Yan Zhongcheng waved his hand:

“I probably won't be directly involved in the Taihang project. Now that I'm getting older and my old injuries have recurred, my body is really struggling.”

 He was seriously injured while doing engine testing before. He didn't feel it when he was young, but as he got older, some stubborn diseases gradually appeared, especially in autumn and winter:

“I plan to continue to engage in aviation-to-gas conversion projects in the future, and it will be good to use some of the remaining heat.”

Compared with the Turbofan 10, which almost completely restarts the stove (in fact, it has not yet been determined where the stove will be and what kind of stove is needed), the work intensity of the aeroderivative fuel project is much lower, and in fact it is not It is closer to the research direction that Yan Zhongcheng was better at in the past.

 Luo Yang and Sun Cong both showed a somewhat pity expression, but when they saw Chang Haonan sitting next to them, they breathed a sigh of relief.

Even if they are not responsible for aviation power, they still know a lot about the role this young man played in the shaping process of the Kunlun engine.

 And Project 11 has an inconspicuous advantage.

 The Su-27 aircraft has a very good air inlet foundation, and the aircraft itself is large, so there is quite a lot of room for engine replacement.

In addition, twin-engine aircraft inherently have a higher safety margin.

In short, as long as the final product is not too bizarre, they can try it first. If it doesn't work, they can even consider installing an AL31F and a turbofan 10 at the same time, so that even if there is a small problem with the latter, it will not cause any problems. Too serious consequences...

“Speaking of aeroderivative gas engines, Mr. Liu happened to mention it just now. I wonder how the modification progress of the turbojet 14-core engine is going?”

 Sun Cong did not continue to dwell on the topic of turbofan 10, but took advantage of the situation and asked about gas turbines.

“We have developed an initial prototype for testing on the 701…”

Yan Zhongcheng had no choice but to repeat what he just said before continuing to add:

“Our final plan is to remove the original low-pressure components, redesign a low-pressure compressor and low-pressure turbine, and then directly drive the load. This can reduce the size of the gas engine and improve fuel economy. For ships powered by full combustion, It is said to be very useful. However, it will take some time to make this final version of the design. We have found several candidate solutions through preliminary numerical calculations, and then we will optimize them and compare their performance. "

 Xu Yang, who was sitting next to Chang Haonan, had not spoken since he saw Chang Haonan and others entering the banquet hall. He just listened quietly to the conversations of others.

Although she usually participates in similar activities within the Chinese Academy of Sciences, she is used to being alone and not actively participating in topics.

But today, especially when Chang Haonan, whom he regarded as a valuable partner, also participated in discussions from time to time, Xu Yang suddenly felt that it was not good for him to stay outside the topic.

By coincidence, I just talked about numerical calculations.

　　is the direction in which she is good at.
