Chapter 558: Unsolvable Problems
Surveying and mapping imitation, it is not so easy, a simple part, you know its dimensions, but when you process it yourself, the processing can not be the same accuracy as others, then the quality gap is big. You know other people's materials and the proportion of various elements, but when you smelt them yourself, you can't smelt the same materials.
There are also many process problems, such as the other party's extra layer of wear-resistant coating on the cylinder wall, and I don't know how to do it.
In this case, how to imitate?
If you want to imitate, you have to reach the original level, the quality of any part is not up to standard, the imitation is inferior, and the overall performance is not up to standard.
When they study carefully, the more in-depth the research, the more chilling the conclusions they get, and they are not able to complete the surveying and mapping imitation, at least in a short time, they will not be able to solve these problems.
This is the gap between the entire industrial system and others.
Just like France, it sells arms all over the world, but people are not worried that their arms will be imitated, take the Mirage 3 fighter as an example, until now, only Israel can imitate it, or because Israel stole all the design materials of the Mirage 3.
It is absolutely impossible to imitate it against only one plane.
The Germans dare to sell this civilian engine, they have enough confidence, they can guess that even if the big countries in the East want to map and imitate, they will not be able to do it, and in the end, they have to obediently purchase diesel engines from Germany, even if they only purchase this civilian model and equip it with their new tanks, it is also a big business, at least a few hundred units.
The tank engine produced by the German MTU company is Mount Everest in the engine field, where is it so easy to imitate.
Take Ah San as an example, they imported all the parts from Germany, and they only assembled them in their own factories, and the problem of this assembly process alone made the original 1500 horsepower engine only able to emit less than 1,000 horsepower.
That's the gap, the huge gap!
Even if the engine is placed in front of you, disassembled, and reassembled, the power data can be reduced by at least 20%~
Now, when Zhang Baolin is making this report, he feels in his heart that it is full of five flavors.
After all, this is a national key project, and the state has invested a huge amount of money, but it has obtained such a result, which is embarrassing.
However, he had to admit that otherwise, continuing the research would only cost more money, and it would be impossible for them to overcome these problems in a short period of time.
"At present, we admit that these problems cannot be overcome in a short period of time, so in order to prevent their tank engines from being affected by our problems, we hope that at this meeting, all experts will work together to come up with a suitable plan."
When Xiang Dayang finished saying this, there was still silence for the time being.
Most of the experts have participated in the last meeting, a few years ago, everyone still attached great importance to this program, thinking that this is the most suitable program, first imitate the civilian model, and then increase the horsepower, and finally reach the same power standard as the Leopard-2.
Now, when I heard about this 8V165 engine and encountered so many problems, in everyone's hearts, it was naturally mixed.
"How can this be, isn't the prototype made?" It was at this point that questions were raised.
"Yes, our engine can't fail, the big guy wants to save face, so we built a prototype first, but, on the bench, the maximum power can only reach 667 kilowatts, which is far from the standard, and this engine can't continue to run stably, all kinds of problems emerge one after another, pull cylinder, fuel injection pump plunger stagnation, supercharger surge A series of problems, are caused by our materials and processing technology, and then later, in order to make it run stably, We kept lowering the power bar to 537 kilowatts, and even then, the problem could not be solved. ”
Now, the domestic coal province diesel engine factory has built a 537 kilowatt engine, which is used in 80 tanks and storm tanks, at least it has been able to run stably, but the engine manufactured by the engine, the original index is high, and as a result, it has been reduced to the current level, and it is impossible to operate stably, and it is far away to overcome these problems.
"Our domestic technology is too backward." Xiang Dayang said: "Take the piston as an example, we don't know how they are processed, by the way, Zhenhua, you say, is there a way to ask a German company to provide some technical support for transparency?" ”
Xiang Dayang is also an expert in the engine institute, and now, putting forward this idea, they can't solve it, and if they want to continue this engine, they can only turn to foreign countries.
Hearing this request, Qin Zhenhua shook his head helplessly: "That's absolutely impossible, our surveying and copying of each other's products is already a violation of the basic international norms, we are infringing, and now, we are infringing on the rights of others, and we are also asking others to provide technical support?" I was afraid of being beaten by the Germans. ”
In China, the concept of technology patents is now slowly forming, if it is a few years ago, these are logical, what about surveying and mapping imitation? Do ideas also count as money? The capitalists are too profitable, right?
Now, everyone can accept it.
"If we don't have their technical support, the future of our project is not optimistic." Xiang Dayang said, his words were full of endless loneliness.
"Let's take a look at the other two diesel engines, in the case of the mapping and imitation project is not going well, we are fortunate to have a backup plan." Said the moderator of the meeting.
In fact, everyone is looking forward to surveying and mapping imitation, which is an expectation to move towards the world's advanced level, and now, this hope has been broken.
There is no diamond, no porcelain work, this project, the state is the most supportive, ask for money to give money, ask people to give people, and concentrate the country's resources to do it, as a result, it has now become a four-like.
Zhang Baolin stood up: "After the end of the last meeting, our coal province diesel engine factory, has developed the X150 diesel engine according to the original plan, through the supercharged and intercooling scheme, in the test run, we got 706 kilowatts of power data. ”
As soon as these words came out, they immediately attracted everyone's attention, the east is not bright and the west is bright, there is always a way, the backup plan here sounds like a lot of progress!
