Chapter 991 QC300, project approval in April!
In fact, from the very beginning, there were no regulations saying that naval gas turbines must go through a bidding process, then model selection, and finally the winner will be decided among the two models.
Just by chance, we now have two suitable gas turbine models on hand.
QC300 obviously has stronger performance and development potential.
However, the localization of GT25000 has been promoted for almost ten years and has consumed a lot of manpower and material resources, so it is impossible to just throw it away casually.
If we put it in developed countries, this is actually not 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 fast to start, and expensive gas turbines are rarely chosen as power.
Until sufficiently reliable and low-cost sources of oil and natural gas are available, it will be impossible to use gas turbines to replace coal-fired boilers for power generation on a large scale.
As for being used as an energy source to drive compressors or pumps in the industrial field...
The prospects are very good, but currently it can only be considered a niche use.
So, everyone unanimously took aim at the destroyer''s power system.
But choosing one now almost means giving up the other.
It’s not just as simple as giving up a model.
??It will also cause a huge blow to the technological development route behind the model.
If these two technical lines can be retained through cooperation, it will obviously be a win-win choice.
?GT25000 is just not suitable as a ship power, it is not really very backward.
With the development of the national economy, if the demand for industrial gas turbines increases in the future, it can still be used to its advantage due to its relatively low cost and the fact that Soviet products are generally not very picky about fuel.
? And even from the perspective of the navy, retaining the gas turbine research and development capabilities of ship systems will leave more paths for the future.
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 reveal his intention immediately, but made a roundabout way first:
“As for specific technical issues... I think it’s better to leave it to professionals to make their own decisions.”
??As he spoke, he glanced in the direction of Yan Zhongcheng and Wen Xueyou, paused briefly, and then continued:
“Of course, if the combination of the two technologies can really improve the final performance of the product, then we as users will definitely be happy to see the results.”
“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 the intercooling cycle.”
“I wonder if there are parts that can complement each other in this aspect?”
…”
In fact, since the idea was first proposed, both Yan Zhongcheng and Wen Xueyou were a little tempted.
For the former, cooperation with colleagues in the shipbuilding industry is itself one of the options that Chang Haonan has considered.
After all, Institute 606 currently has three ongoing projects, namely Turbofan 10H, M88-3 and SeA650, plus a fourth-generation engine, which is the pre-research of Turbofan 10G.
?Although the plan for the subsequent Turbofan 20 is led by Hao Jing, 606, as the big brother in the aviation development field, certainly cannot not contribute at all.
The resources and manpower that can be allocated to QC300 are already quite tight.
For Jacky Wen, if he insists on carrying out model selection, the result can only be total victory or total defeat.
But 703 Institute is not as big as the other company, and GT25000 is a project that they must ensure to be foolproof.
If orders from the navy are completely lost, development will be very difficult in the next few years or even longer.
?In this case, a safe option that although it will not win, but will certainly not lose, is undoubtedly more tempting than direct stud.
Besides, looking at the current posture, if this shuttle really goes down...
The winning rate may not be optimistic.
?However, it is one thing for them to be tempted, and another thing to actually agree.
Although cooperation does not mean that two models are merged into one, in any case, this is a cross-group behavior, and it also involves a rather complicated issue of interest distribution.
It is by no means a matter of blending between the two chief divisions. Therefore, it is impossible for either of them to express their stance.
“Director Li.”
??It is definitely not an option to remain deadlocked like this, so in the end, Yan Zhongcheng broke the silence:
“I’m afraid a final decision on this matter needs to be made at the group level, but after I return, I will report the thoughts of my naval comrades as soon as possible.”
“From a personal perspective, I think cooperation is feasible.”
Jacky Wen, who was 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 comrades in the shipbuilding industry still have full trust in us..."
Chang Haonan was in a good mood with his curiosity satisfied:
“Since Mr. Zhu can propose the second major modification plan, it shows that they have already considered the possibility that the QC300 gas turbine can be installed on ships and put into use in a short time. This is a major benefit to us.”
? Zhu Fuying’s two plans, the first is basically a replica of the 052D from the previous life. Even the power is the same two GT25000 plus two license-produced MTU956. There is 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.
However, after improving the aspect ratio, the space and seaworthiness of the ship have been greatly improved.
As for motivation…
?At a certain moment just now, Chang Haonan even thought of the relatively radical alternating combustion-burning drive form.
That is, two high-power QC300 models are used as propulsion gas turbines at high speeds, and two low-power models are used as cruise gas turbines at low speeds.
Unfortunately, cruise gas turbines only require a total of 8-10 MW of power, so even a single 13 MW QC130 is still too big.
? So there is a high probability that we will still have to go back to the alternating diesel-fuel system of two QC300s and two MTU956s.
"Actually... they mainly trust you, Mr. Chang."
Yan Zhongcheng’s words are absolutely sincere:
“The QC300 itself has not even been approved yet, but the results of the Turbofan 10 are real and can be seen by everyone.”
“Don’t put the credit on my head either.”
Chang Haonan waved his hand:
“On the other hand, if there were no QC130 Zhuyu in the lead, which has successfully passed the test and been installed on the 054, others may not be optimistic about the technical route of aeroderivative gas turbines.”
“After all, before that, the performance of several aeroderivatives produced by our aviation industry system was generally not mentioned, and the research and development process was... quite tortuous.”
The "more tortuous" models in his words are mainly the turbojet 6G, which was intended to be used as a ship power source but failed, and the Spey Aircraft Diesel, which was stillborn.
It can be said that if the Turbojet 14 had not entered Lin Qing''s sight at the very right time, thus giving birth to the QC130, the 606 Institute might not even be able to get tickets for naval equipment selection.
After some mutual compliments, Yan Zhongcheng returned to the topic:
"Mr. Chang, please take a look...the cooperation proposal put forward by the Navy..."
“As long as the model is mainly QC300, then I have no objection.”
Chang Haonan immediately replied:
“Of course, a formal decision may require a meeting of the leadership team to make, but the result should not be in any suspense... It mainly depends on whether the other party is willing to join our R&D team.”
“Besides, since we have to cooperate with others, we can’t continue to be anonymous. We must have a formal project anyway.”
“Mr. Yan, please prepare relevant materials when you go back. After I am busy in March, I will try to complete the QC300 project approval work before the end of April!”
