On the fourth day when Yang Hui and Director Bai discussed countermeasures, the investigation team from the imperial capital rushed to the institute in the dust.

The team is led by Wu Lao and another slightly younger office director, Wu Lao came to the base naturally for no reason, must be a strong support for the base, and another person who came with him is said to be responsible for the first standard, the director of the office in charge of the formulation of scientific research outline standards.

When the group came to the base, they looked unkind, and first asked for access to all the R&D materials, although these were a little annoying, but Director Bai still took this person to the data room to check the information. If nothing else, it will take a few days to delay, and the method discussed by Yang Hui and Director Bai will take a few days to complete.

The investigation team reviews the design data very carefully, and if they have time, these people will go through the design process again to thoroughly get the first-hand information for comparison, of course, provided that the people in these investigation teams have scientific research ability.

For three days, the investigation team was rooted in the data room except for eating, drinking, and Lazar, and the responsible attitude of the investigation team alone was very admirable.

Holding the thick information, the person in charge of the investigation team finally walked out of the data room, and the dark circles under his eyes were very shocking, but this one didn't care.

"Bai Kang, hello. Now that our investigation team has specific information on your research and development process, it has been proved that you did not design in accordance with the design outline stipulated by the state, there is no doubt about this. Now we are going to investigate your problems in depth, and you must cooperate unconditionally. ”

Unconditional cooperation, there is no way to do this, do things in the system, and meet the investigation team sent by the superiors, no matter how awesome you usually are, you have to deal with it at this time.

Director Bai doesn't have much resistance to this, anyway, everything is arranged, as long as there are no big mistakes now, the final outcome depends on the will of God, and all the efforts that the base can do are done.

"No problem. I will cooperate during the investigation, but before I do so, I would like to say something that I believe is extremely important and beneficial to both sides of the investigation. ”

The head of the investigative team. The reform of the engine plant in the southwest was quite angry at first, and in all fairness, it was not impossible to revise the design specifications, but the changes were carried out under the guidance of a special office of the central government.

Now let a local scientific research institute modify it privately, this is a big problem. This can be regarded as a local robbery of the central government's work, can this kind of thing be good when it is said?

The leader of the investigation team is a member of the central office responsible for revising the norms, and it is natural to be able to see whether some of the norms revised by the base are good or bad. But sometimes that's the case, it's not just that you can be welcomed and rewarded for your good work.

"Let's say, our investigation team still has to ask for the opinions of the parties in your base, this is a discipline that must be observed."

Director Bai handed the folder to the person in charge: "Team Leader Zhang, this is the development schedule of our new engine, according to our body situation, the development of the core engine of the new engine has been mostly completed. In the next few days, the core machine test will be carried out, and I think it is necessary for the investigation team to look at the results of this machine test before making an evaluation. ”

That's right. Now the base has entered a new stage in the trial production of the new engine, and there is no test of the core machine, but the test results of the parts and components of the core machine have been obtained, and according to the analysis of the test results, there is no problem in installing the core machine test.

"The development of your new engine is so fast, who believes this, even the old engine modification is not so fast, and now you say that you want to test the whole engine, and now a year has not yet arrived, what do you think you are doing?"

Engine testing. It seems that this team leader Zhang did not understand what Director Bai meant, and there is a big difference between the whole machine test and the core machine test.

"Director Zhang, you misunderstood, what we want to test is the core machine. It is made up, a gas generator, and is only the most core part of the engine. These are the advanced experiences we have gained about the engine development process after our external exchanges, and these are the first things we have introduced. ”

Core machine, this concept has been heard of. However, this team leader Zhang is not engaged in scientific research, so naturally he does not fully understand, but it is the advanced experience of Western countries, so let's see what kind of artifact this core machine is.

"Yes, I see that the whole test of this core machine is a matter of the past few days, and we will see how the engine you make up yourself is, so that our investigation will be detailed and credible."

Until now, this team leader Zhang still has no hope for the new core machine, if the engine development can be so simple, the country has not been able to get a satisfactory engine until now?

Team Leader Zhang doesn't engage in technology and doesn't understand the core machine, so naturally there is nothing to say, but Wu Lao, who is also in the investigation team, knows what the core machine is.

Wu Lao heard Director Bai say that he wanted to test the core machine, and he understood Director Bai's method of dealing with the investigation team, and the investigation team is now down, and the timing is very good, if it is according to the previous engine development process of the Republic, the base will really not be able to come up with things now, but now the new development process, there is the concept of the core machine.

If the core engine is really performing very well, then there will be a turning point for the base not to develop engines in accordance with the development specifications stipulated by the state. Thinking of this, Wu Lao was relieved, and the method he prepared could be put first, after all, this method was not too suitable.

The investigation team agreed to take a look at the test situation of the core machine first, then the problem began to turn in a good direction, Director Bai had to continue to do the preparation for the test of the core machine, and it was not simple to do the preparatory work in the early stage of the test, and the fuel used for the test alone was enough for the test center to be busy for a long time.

The assembly of the core machine is much simpler than the assembly of the whole engine, but the assembly of the compressor is still more technical, fortunately, the current director of the Liyang plant is the director of the Bai director, and it is very simple to transfer skilled workers to assemble.

The blades of the compressor are still using the old-fashioned process, and group assembly is a helpless choice, and now it is tolerable in the test of the new machine, but when it comes to mass use, it is a little difficult.

Fortunately, the base has contacted the British side to prepare to import some processing equipment, and first carry out a major upgrade of the processing capacity of the most critical Liyang plant of the base. In the 80s, it was still possible to import Western precision machining equipment, although it was necessary to give more money, but to be able to import equipment was a victory.

The assembled core machine already looks like an engine, although there are no secret pipelines covering the outer surface of the receiver, but the necessary interfaces are just right.

The core machine is transported from the Liyang factory to the test center for testing, and the core machine test does not have too high requirements for test equipment, which can be met by the base test center.

The core machine fixed on the test frame has not yet arranged the fuel pipeline, the fuel is connected to the combustion chamber, and the fuel pipeline needs to be simply arranged, and the test on the bench is relatively simple, and the volume is not required like the finished engine, and now it only needs to ensure that the fuel can be guaranteed when the core machine is running.

Of course, the test of the core machine also has requirements for air, and without the pre-compression of the low-pressure compressor, a special design is required to pre-compress the airflow. Fortunately, these problems can still be solved in the test center, and the overtime preparation work makes the test center finally busy.

In order to ensure that the test team can start smoothly when the investigation team comes to participate in the machine test, the test center conducted the test in advance, and the results obtained also made the test center feel confident.

This kind of important people to participate in the first test, test flight, sea trial and other major projects, almost all of them have to be secretly tested first, these are unwritten rules, the so-called first test is just talk. (To be continued.) )
