Chapter 240 Aircraft control is also difficult (Part 1)
Not all participants were qualified to follow the two leaders all the way, so when Chang Haonan and the others were led by the staff to the banquet hall By the time, most people had been waiting here for some time.
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 is still some time before the banquet officially starts, so everyone is not in a hurry to take a seat.
“Speaking of which, Mr. Yan, did 701 mention other design elements of that new model of frigate?”
Chang Haonan is quite interested in this model that he already knows will be designated 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 Commander Lin did say it, 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 three ships in front will be used directly. Each 6-seat, 8-unit 3K95 short-range air defense system imported from the Antai Scientific Research and Production Complex is said to have the same origin as the 9K331 field air defense system that the Army is purchasing. This will reduce the number of ammunition production units after the introduction of production lines or imitation in the future. pressure.”
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.
Of course this is 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 needs to be removed and replaced with the same 8-gun launch box of the same style as the Land-based Doyle.
However, Chang Haonan was still a little surprised by this uncoordinated configuration:
“With 48 rounds of ammunition, so many?”
Although the performance of the 3K95 system is better than that of the 052 destroyer The Sea Sidewinder/Haihongqi 7 installed on it is much more powerful, but the 9M331 missile it is adapted to is a short-range point air defense system with a range and 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 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, the ship is also equipped with a total of 6 channels of anti-aircraft missile illuminators, so several more launch devices were designed."
At this point, Yan Zhongcheng paused and stroked it gently. He rubbed 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 has to leave some space. It will be done sometimes, but there is no need to fill all these places.”
“The real reason may be that the frigate they built is indeed a bit large, both in terms of full load displacement and hull size. It’s similar to the 052 destroyer that just entered service. If we don’t find a way to increase the hull utilization rate and prove that it is necessary to design such a large hull space, I am afraid there will be 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. Listening to Yan Zhongcheng's description, It should be 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, your Chinese navy is actually preparing to equip a model with performance and size that is better than similar ships in the US military in one step, even if it is just an inconspicuous frigate. It is also an act of treason and transgression.
"Well... 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. Objection The sound will also be weaker.”
Yan Zhongcheng glanced at Chang Haonan in surprise:
"When Deputy Chief Lin talked about this matter with me, he said almost exactly the same as you. But what he meant was that the key parts of the diesel engine that were originally expected to be imported Part of the foreign exchange quota should be used to enhance the anti-submarine system, otherwise the high speed and high quietness brought by full combustion power will be wasted. "
Yes, it seems that it is indeed going to benchmark and surpass Perry in all aspects.
After briefly learning some information related to the new frigate, Chang Haonan brought the topic back to Yan Zhongcheng’s old profession:
“The 701 Institute has such a bold idea and thinks of all functions. One point, our power requirements are not low. ""It is indeed not low, but according to the method you communicated with Shipbuilding Industry before, Xiaochang, we have already developed a method that eliminates the exhaust nozzle and uses the dual-rotor structure. As a gas generator for a gas turbine, a simplified design of a power turbine will be used for technical verification. Factory 410 will start producing the prototype soon. If nothing else, it will be delivered in mid-June. Let’s get that first Let’s start the ground test, which will give us 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."
The formal banquet here at Sanzuomen naturally 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’s not 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 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 speaker is the current general manager in charge of the overall Project 11 project. Luo Yang.
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 of acute myocardial infarction and sudden cardiac death. Died in the line of duty.
Of course, in 1997, he is still at his most youthful and powerful state:
“According to the agreement, Project 11 does not include the matching AL31F engine. We are thinking that since in the future This aircraft is about to become our own J-11. It is not a problem to import aviation engines from the Russians. I think the situation on the No. 10 Project should be similar. It would be best to synchronize it with the J-8C. By replacing it with domestic power, we can also 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 money in the future. It would take a second time, so he is very concerned about the progress of the domestically produced third-generation turbofan 10.
However, Yan Zhongcheng waved his hand:
"I shouldn't be directly involved in the Taihang project. Now that I'm getting older, and with the recurrence of old injuries, my body is really too much."
He previously I was seriously injured while doing engine testing. I didn’t feel it when I was young. But as I get older, some stubborn illnesses have gradually emerged, especially in autumn and winter:
“I plan to continue to do a lot of work in the future. It would be nice to use some of the waste heat in the aviation-to-gas project."
Compared to almost completely restarting the stove (in fact, we haven't even determined where the stove will be and what kind of stove is needed). For the Turbofan 10, the work intensity of the aeroderivative combustion project is much lower, and it is actually closer to the research direction that Yan Zhongcheng was better at in the past.
Both Luo Yang and Sun Cong showed some pity, but when they saw Chang Haonan sitting next to them, they breathed a little 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 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?"
Sun Cong also Instead of continuing to dwell on the topic of turbofan 10, he took advantage of the situation and asked about the gas turbine.
"We have already produced an initial version of the 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.
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 discussions from time to time, Xu Yang suddenly felt that it was not good for him to stay away from the topic.
Coincidentally, I just talked about numerical calculations.
It's what she's good at.
