Chapter 240: It Is Also Difficult to Conduct Air Traffic Control (Part 1)

Not all the participants were qualified to follow the two big 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 their seats.

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

Chang Haonan is quite interested in this model that 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 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 smooth 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 real 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 lives.

This is certainly 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 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-link launch box of the same model as Luji Doyle.

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

"With 48 rounds of ammunition, that's a lot?"

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.

Unlike 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 cram in as many as 48 rounds.

What kind of scene? Can the terminal interceptor fire so many bullets?

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 sets of launch devices were designed.”

Having said this, Yan Zhongcheng paused, gently touched his temples, and then continued after thinking for a moment:

"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 based on suspicion. .

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 nationally produced subsystems. In this way, 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:

"Institute 701 has such a bold idea and wants a little bit of every function. It requires a lot of power from us."

"It is indeed not low, but according to the method you communicated with Shipbuilding Industry before, Xiaochang, we have developed a gas generator that removes the exhaust nozzle and uses the dual-rotor structure as a gas turbine, and then equips it with a power We will give them a simplified version of the turbine design for technical verification. The 410 Factory will start producing prototypes soon. If nothing goes wrong, it will be delivered in mid-June. Let them start the ground test first, which can also add value to us. Have some confidence."

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 here 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's table are still old acquaintances in the aviation industry.

In addition, there is Xu Yang, the only one 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 speaker was Luo Yang, who was 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 in charge of the overall project, it is of course best to complete these things in one step to save the trouble of having to do it twice in the future, so he is very concerned about the progress of the domestically produced third-generation turbofan 10.

However, Yan Zhongcheng waved his hand:

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

He had been 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 work on aerospace-to-gas conversion projects in the future, just 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.

Both Luo Yang and Sun Cong showed some regretful expressions, 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, the role played by this young man in the Kunlun engine finalization process is still known.

And Project 11 has an inconspicuous advantage.

The air intake of the Su-27 aircraft is very good, and the aircraft itself is large, so there is plenty of space 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 instead asked about the gas turbine.

"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 separately and compare the 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.

When 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 the discussion from time to time, Xu Yang suddenly felt that it was not good for him to stay away from the topic.

It just so happens that we just talked about numerical calculations.

It's what she's good at.
