Chapter 991 QC300, Project Launched in April!
In fact, from the beginning, there was no regulation that ship-use gas engines must go through a bidding process, then select models, and finally decide the winner between two models.
It just happened that there are two gas turbine models available now.
The QC300 obviously has stronger performance and development potential.
But the localization of GT25000 has been pushed for nearly ten years, consuming a lot of manpower and material resources, and it is impossible to just throw it away.
If it were in a developed country, this would not be a problem.
But China does not have a large enough market to accommodate two competing products at the same time-
Civilian ships do not need to be quiet and start quickly, and rarely choose expensive gas turbines as power.
And before obtaining a sufficiently reliable and low-cost source of oil and natural gas, it is impossible to use gas turbines on a large scale to replace coal-fired boilers for power generation.
As for using it as an energy source to drive compressors or pumps in the industrial field...
The prospects are good, but it can only be regarded as a niche use at present.
Therefore, everyone has set their sights on the power system of destroyers.
But now choosing one of them almost means giving up the other.
It is not as simple as giving up one model.
It will also cause a huge blow to the technical development route behind the model.
If these two technical lines can be retained at the same time through cooperation, it will obviously be a win-win choice.
GT25000 is just not suitable as a ship power, not really backward.
With the development of the national economy, if the demand for industrial gas turbines increases in the future, it can still play a role with its relatively low cost and the fact that Soviet goods are not picky about fuel as usual.
And even if it is only from the perspective of the navy, retaining the gas turbine research and development capabilities of the ship system is also leaving more ways for the future self.
Only when the number of Party B is greater than or equal to two, Party A can enjoy the pleasure of being a father.
However, Li Jiang did not immediately express his intention, but first made a roundabout way:
"Specific technical issues... I think it is better to leave it to professionals to judge."
He glanced in the direction of Yan Zhongcheng and Wen Xueyou, paused for a moment, and then continued:
"Of course, if the combination of the two technologies can indeed improve the final performance of the product, then we, as users, will definitely be happy to see it happen."
"In addition, I remember that Mr. Wen just said that the 703 Institute has completed a principle prototype of intercooling and heat recovery, and Mr. Yan is preparing to build a two-dimensional component-level model including intercooling cycle."
"I wonder if there are also complementary parts in this regard?"
"..."
In fact, since this idea was just proposed, both Yan Zhongcheng and Wen Xueyou were a little tempted.
For the former, cooperating with colleagues in the shipbuilding industry is itself one of the options considered by Chang Haonan.
After all, the 606 Institute currently has three ongoing projects, namely the WS-10H, M88-3 and SeA650, and a fourth-generation engine, namely the preliminary research of the WS-10G, is also needed.
Although the WS-20 is planned to be led by Gaojing, the 606 Institute, as the big brother in the field of aero engines, certainly cannot do nothing.
The resources and manpower that can be allocated to QC300 are already quite tight.
For Wen Xueyou, if he insists on carrying out the selection, the result can only be a complete victory or a complete defeat.
But the 703 Institute is not as big as the other party, and the GT25000 is a project that they must ensure is foolproof.
If the order from the Navy is completely lost, the development in the next few years or even longer will be very difficult.
In this case, a safe choice that will not win but will definitely not lose is undoubtedly more tempting than going all-in.
Moreover, looking at the current situation, if this one really goes all-in...
The winning rate is probably not optimistic.
However, it is one thing for them to be interested, and it is another thing to actually agree to it.
Although cooperation does not mean that the two models will be combined into one, it is a cross-group behavior anyway, and it involves quite complicated interest distribution issues.
It is definitely not something that can be agreed upon by the two chief designers.
Therefore, neither of them can express their opinions.
"Director Li."
It is definitely not a solution to keep the situation deadlocked like this, so Yan Zhongcheng finally broke the silence:
"I am afraid that this matter needs to be decided at the group level, but after I go back, I will report the ideas of the navy comrades as soon as possible."
"From a personal perspective, I think cooperation is feasible."
Wen Xueyou next to him immediately made the same statement:
"I personally think that cooperation is feasible. After I go back this time, I will report the situation and my personal opinions to the group for reference..."
...
After the two-day seminar, Yan Zhongcheng immediately found Chang Haonan and briefly described the meeting to the latter.
This naturally includes the two improvement plans proposed by Zhu Fuying for 052C -
This is what Chang Haonan specifically told Yan Zhongcheng to remember before.
"It seems that the navy and the comrades in the shipbuilding industry have given us full trust..."
Chang Haonan was in a good mood after his curiosity was satisfied:
"Since President Zhu can propose the second major modification plan, it means that they have long considered the possibility that the QC300 gas turbine can be installed and put into use in a short time. This is a major benefit for us."
Zhu Fuying's two plans, the first one is basically a replica of the 052D in the previous life, and even the power is the same two GT25000 plus two licensed MTU956s, nothing to say.
But the second one is really in line with Chang Haonan's wishes.
The displacement of 8,000 tons means that the cost will not skyrocket.
But after improving the aspect ratio, the space and seaworthiness of the ship are greatly improved.
As for the power...
At a certain moment just now, Chang Haonan even thought of a relatively radical fuel-fuel alternating drive form.
That is, two high-power QC300s are used as propulsion engines at high speeds, and two low-power models are used as cruise engines at low speeds.
Unfortunately, the cruise engine only needs a total of 8-10 MW of power, so even a single 13 MW QC130 is still too large.
So it is likely that we will have to return to the diesel-fuel alternating form of two QC300s plus two MTU956s.
"Actually... they mainly trust you, Mr. Chang."
Yan Zhongcheng's words were absolutely sincere:
"QC300 itself has not even been approved, but the achievements of WS-10 are real and everyone can see it."
"Don't push the credit on me."
Chang Haonan waved his hand:
"From another perspective, if there was no QC130, which had successfully passed the test and was installed on the 054, others might not be optimistic about the technical route of the aircraft-derivative fuel engine."
"After all, before that, the several aircraft-derivative fuel engines developed by our aviation industry system had average performance, and the research and development process was... more tortuous."
The "more tortuous" models he mentioned were mainly the turbojet 6G that wanted to be used as a ship power but failed, and the Spey aircraft-derivative fuel engine that was directly aborted.
It can be said that if the turbojet 14 had not entered Lin Qing's sight at a very appropriate time, thus giving birth to the QC130, the 606 Institute might not even be able to get a ticket to the naval equipment selection now.
After a round of mutual flattery, Yan Zhongcheng returned to the main topic:
"Then Mr. Chang, please look at the cooperation proposal put forward by the Navy..."
"As long as the model is mainly QC300, I have no objection."
Chang Haonan immediately replied:
"Of course, the formal decision may require a meeting of the leadership team to make, but the result should not be suspenseful... It mainly depends on whether the other party is willing to join our R&D team."
"In addition, since we are going to cooperate with others, we can't continue to be nameless and without division. In any case, we must have a formal project."
"Mr. Yan, prepare the relevant materials after you go back. After I am busy in March, I will try to complete the project establishment of QC300 before the end of April!"
