Chapter 956 The sample is provided by us
Faced with Liu Yongquan’s explanation, Ian Vista fell silent for a moment.
After all, what the former said makes sense.
We need to improve performance without reducing reliability, and without increasing costs and working hours...
How can I let you take advantage of all the good things?
And compared to the first two, it seems that the third point is indeed a relatively less important thing.
After all, the French navy and air force are limited in scale, and they don’t actually need many Rafales.
This leads to the fact that in the quotations of the first few batches of products, the shared R&D expenses actually account for the majority, and the production costs are only a small part.
Therefore, the increased cost of engine manufacturing is not obviously reflected in the price of the whole machine.
Not to mention, the bare metal price of Rafale is almost only about 60% of that of its competitor Typhoon.
Even if the price goes up slightly, as long as the performance can keep up, the overall advantage is still great...
However.
Money, after all, is only one aspect.
The world is material. It does not mean that if you have money, engines can grow out of thin air from the production line.
The problem is still working hours.
As a veteran who has been immersed in the aviation field for most of his life, Vesta naturally does not just talk on paper.
On the contrary, he actually came from a factory and has a fairly clear understanding of the production process.
As for the design now posted on the PPT, compared with the simple fan-shaped air film hole used on the M88-2, the processing difficulty is not at the same level.
It takes at least 3-4 times the time to process each leaf.
It is equivalent to the production capacity directly changing to about 30% of the past.
This still does not take into account the problem of reduced yield caused by complex processing processes.
In actual operation, it is not an exaggeration to directly reduce it by an order of magnitude.
Of course, if this is only the case with the M88-3 engine, it is not unacceptable.
Anyway, the installation target is Guafeng, so the slower it is, the slower it will be.
But as Liu Yongquan said just now.
In the future, SeA series engines will also use this hot end design.
That is the driving force for Dassault’s business jets and even the regional passenger aircraft product line that may appear in the future.
The demand is still slightly larger.
And the civilian aircraft market is an open, at least semi-open, competitive field.
If there is really a delay in delivery, it is not something that military planes can just punish themselves with three drinks and get over.
The liquidated damages must be at least large...
For a while, Vesta was in a tangle.
But...
He soon realized that he seemed to have nothing to worry about -
Because the design process was now controlled by others.
Snecma claims to be a partner, but in fact it doesn’t have much say at all.
And when the M88-3 indicator requirements were mentioned before, working hours were not mentioned.
At Dassault, there are many Rafale Cs that have already built their airframes and are waiting to be delivered with engines installed.
Whether it was from the perspective of the contract or the actual situation, he had no possibility of rejecting this design plan.
No choice.
If it doesn't work, we can only consider expanding the scale of the factory.
"Mr. Vesta."
At this moment, the voice from the opposite side finally woke Vesta out of his thoughts.
The speaker was naturally Liu Yongquan:
“Now, we have introduced the main performance of the high and low pressure turbines after the upgrade. Next, in order not to delay the development schedule of these two engines , I hope you can complete all installation tests by the end of this year...and by February next year at the latest, so that we can start the next phase of design work..."
"?"
Hearing this request, Vesta, who had just managed to persuade himself to calm down, was shocked:
"Wait...wait."
He quickly stopped Liu Yongquan:
“Today is already...November 19th.”
Vesta pointed to the watch on his wrist and said with a ghostly expression:
“After we go back, we still need to organize the information, verify the process, organize production...we can only conduct testing after the quality has stabilized. , and there is a Christmas in the middle, how is it possible to get the test results out in such a short time?”
“Well...” In fact, this film cooling solution was developed by Chang Haonan after all. In addition, component-level testing has been conducted, so Liu Yongquan is relatively confident that the next step of design does not really have to wait until the testing is completed before starting.
The reason why I just said that is just to increase the strength of Snecma.
However, Liu Yongquan did forget about Christmas and thought that the end of January was just before the Spring Festival.
A bit embarrassing.
However, at this critical moment, you must not swallow what you say. You can only continue to act according to the script:
"Then...according to your estimation, this round of testing will be about When will it be completed? ”
In fact, from a technical perspective, the component installation and testing can also be done directly in China.
It's just that Snecma is the de facto "Party A" after all, and it has to check it, so it specifically stipulates the ownership of each test in the contract.
Vista did not respond immediately, but lowered his head and pondered for a moment.
"Probably... we can try to complete the entire project before June next year."
"..."
This answer directly made Liu Yongquan laugh:
"Dr. Vesta, let's not talk about the M88-3 for now."
"According to Dassault's plan, the first prototype of the Falcon Z will fly for the first time in 2003. If a The hot-end component testing has been postponed until next June, so how are you going to ensure that the SeA650 engine for the first flight will be provided to Dassault before the end of 2003? "
"This..."
Maintenance Star was speechless.
When the SeA series engine development plan was finalized, the development of the hot end was completely handed over to Huaxia, so he did not expect that the other party would come up with such a complex design.
Now that we are facing the construction deadline issue, I am really sweating.
And Liu Yongquan is naturally pressing harder:
"In addition, if a breach of contract is caused as a result, will the liquidated damages be borne solely by Snecma?"
"..."
A few minutes ago there was a harmonious atmosphere, but because of this sentence, it suddenly became a little anxious.
For a moment, the conference room was quiet and only the sound of Vesta's slightly heavy breathing could be heard——
The old man had not had much rest in the first place, and he had just managed to cheer himself up before the meeting started, and now he was again Being so excited, I actually felt a little dizzy.
Liu Yongquan, who was sitting across from him, also noticed that Vesta's body was shaking slightly, and his heart sank suddenly. He thought to himself that I might have made the old man faint because of my excessive firepower just now. ...
Fortunately, the latter quickly opened his eyes again:
“From the implementation of the drawings to the product, the time required for this process is determined by the specific design. The plan is so complex that we naturally need to spend longer time preparing for the test. This is normal..."
Seeing that everything seemed to be normal in Vista, Liu Yongquan finally breathed a sigh of relief.
However, he didn't dare to use too much force.
If the other party is angry to death in China, it will undoubtedly not be a good thing for both parties.
So, Liu Yongquan temporarily decided to delete the remaining parts of the script and fast forward directly to the most visible part:
"Let's do this, Dr. Vesta."
He deliberately acted like "I really can't do anything to you":
"We at China Aviation Industry Group can provide a complete set of finished products for the turbine parts required for installation and testing. You can start testing directly after you bring them back. process, and then feedback the results to us.”
“Of course, according to the agreement, we will still provide the production-related process and technical data, if you want to reorganize production and testing yourself in the future. , we won’t interfere.”
Vista frowned slightly.
This plan sounds like the best of both worlds.
The test itself actually doesn't take long, and if the samples are readily available, it won't be difficult to get the results before the end of the year.
The research and development of SeA series engines will also not be affected.
As for Snecma's production, it can proceed normally according to the plan, and there is no need to rush or slow down in order to match the efficiency of China.
But somewhere, he just felt like something was wrong.
"So...do you have a ready-made sample in hand?"
Vesta decided to confirm a few more details.
“No.”
Liu Yongquan shook his head:
“We have used all the samples produced before when we tested them ourselves.”
Vesta thought to herself, "I'm afraid you're kidding me. If there's no ready-made product, wouldn't we have to re-produce it, which would save the time of process verification?"
However, before he could think of what to say, Liu Yongquan had something else to say:
“However, we can guarantee to produce a complete set of new samples within ten days, so that we can still leave you with It will take at least one month.”
“Considering that this round of testing does not involve the issue of the full life cycle, one month should be enough.”
