The test bench was about to begin, and there was a large group of people in the distance, and the members of the investigation team were standing in a far safety area, equipped with thick protective equipment, although there were very good protective measures on all sides of the test area.

Although the test center had tried it once a year ago, it was still uneasy when it came to the end. Director Bai, Chief Teacher Wen, and Chief Master Yang were the most concerned, but at this time, they could only sit quietly on the side, waiting for the test to start.

All the conditions are in place, this time there is no exciting countdown, no preparation of the posts to report, because these are ready, just order to start testing.

"The test begins, and each unit starts the core machine test sequence in order."

The language was flat and did not fluctuate at all, but it was hanging high in the hearts of everyone at the scene, and as the whistling sound of the core machine gradually increased, and operated smoothly, the crowd erupted into a burst of cheers, which lasted for a long time.

After so many years of design, Mr. Wen is still a little worried about the new design process, but after the core machine successfully realized its autonomous operation, Mr. Wen cried with joy.

"Good, good. Our first step is to take a step, and then it depends on our hard power in design and manufacturing, so we are ready to wait. ”

The excited Chief Designer Wen and Chief Engineer Yang hugged each other, and the excitement was beyond words, but Li Jufeng, who was on the side, was still worried. The high-temperature turbine has not yet tested the final data, which is directly put into the core machine test, and there is still no bottom in my heart.

Li Jufeng's worry was shown on his face, and Chief Master Yang walked over to comfort him: "Lao Li, don't worry, the high-temperature turbine you are responsible for is the first big project to produce results." Now that the high-temperature turbine has not tested the last service life, doesn't it mean that there is no problem with the new high-temperature turbine, and we should be happy about this. ”

"Yes, it's because I'm thinking too much, I'm too concerned about this project, and some of my concern is messing up, and our high-temperature turbines have been running for at least 500 hours. In the end, this will definitely exceed the first overhaul time of the combustion chamber, and if there is no problem, the first overhaul of our core machine can be set at 500 to 600 hours, which is far more than our turbojet 7. ”

The first test run of the core machine, as long as it can operate autonomously, it is a success. After three hours, the core machine stopped, and since the first test run was not at full power, the data were not very convincing.

However, the success of the core machine is the biggest good news, and the investigation team has forgotten the reason for their original purpose for the time being. Congratulations on the success of this test run.

"Okay, this is the first step to success, or congratulations, if the new core machine can come up with results this time, maybe there will be a turnaround in your private revision of the national military standard this time."

What Team Leader Zhang said was what he said in his heart: As long as there is a breakthrough in such a high-tech project as aerospace, it is worth rejoicing for a long time, and although the current position is different, the joy is the same.

After a short break, another core machine was also installed on the test bench. With the experience of the first test, this test will further increase the power.

At the same time, the first core machine is disassembled for testing, and if it is qualified, it will be assembled again, and when the second core machine stops for testing and inspection, the first machine will be installed on the test bench again to continue testing, which can save time to the greatest extent and maximize the use of the test bench.

After five days, the core machine test reached the maximum power, the entire core machine test reached the expected goal, and the data were placed on the desk.

"Look at it. Team Leader Zhang, the data of our new core machine seems to be able to meet the requirements of our new engine in terms of thrust. ”

The data of the core machine, a new thing, Team Leader Zhang doesn't understand it very much. However, this did not affect Team Leader Zhang's judgment, and he glanced at the data of these core machines, and compared the data of the vortex jet seven core machines next to him, it seemed that he had made great progress, and these were enough.

"Well, I've seen this. This core machine data is like this, barely qualified, but these do not reflect the overall level, our aero engine still depends on reliability, life and so on. ”

Team Leader Zhang's words undoubtedly reflect what he meant, that is, to see the life and reliability of the engine, to test these problems, it will take a long time.

But there is no problem with this, the investigation team is willing to wait and let the investigation team wait, and now it has just passed the New Year, and everyone has nothing to do, so they will do the test.

Testing life is not an ordinary trouble, there is no shortcut, it can only be a hard to burn fuel, and run the engine desperately. It is calculated according to the estimated life of 500 hours to 600 hours in the first turn.

It is impossible for an engine to run without stopping, and the average military aircraft will run for several hours at most, and then it will land and stop, and the engine will stop running. It runs for twenty hours a day. Even if it takes 500 hours to run for that long, it will take a month.

After these time tests, the core machine designed according to the damage tolerance will theoretically have reached the first turning period, but the base has to do a lot of things during the month, and this time should not be wasted.

The design of the new engine has not been designed in accordance with the old standard specifications from the beginning, and the new specifications have a lot of British standard elements, and the United Kingdom, as the birthplace of the Industrial Revolution, naturally has their own set of industrial specifications.

The investigation team has been at the base for more than 10 days, and has witnessed the use of the new norms, and there is not much resistance to the revision of the norms themselves, so naturally there is no reason to stop the development of the new engines, and they have the right to investigate, but they have no right to decide.

"Director Bai, take out the British norms you use, let's take a look, our investigation team still has the right to check them."

I heard that the investigation team wanted to check the British norms, and Director Bai didn't know what to do, this thing was handed over to the institute by Wu Lao, so it's better to ask Wu Lao's opinion.

Seeing that Bai Kang and this kid surrendered his gaze to himself, Wu Lao understood what Director Bai was worried about, and nodded affirmatively, saying that he could take out the British norms.

The wooden box was lifted out, and there were some English standards that had been used inside, and the old versions of the standards modified according to these specifications had been modified, so there were still modified standards in the box.

Team Leader Zhang is the director of the Office of Revision of the Standard Specification, and naturally has an unusual sensitivity to these military standards, comparing the old military standards, the British standards, and the new military standards. After some comparison, I have to admit that the new military standard does have a lot of advantages.

Compared with these new military standards that have been preliminarily formed, this team leader Zhang also fell into contemplation, as the director of the office responsible for the revision of the military standard, there are some more reliable gossip about the revision of the military standard.

In fact, in the early eighties, the aviation system and the army had voices demanding that the old military standard specifications be revised, and the old military standard specifications were unbearable, which was not only seen by the base, but also seen by many aviation-related units.

I saw the mistake, but there were several different voices on the way to take in revising military norms, and there were conservatives, who advocated revising the old norms in accordance with Soviet norms, and it was easier to connect Soviet military norms with domestic military norms, and at the same time, Soviet military norms had already been obtained through special channels;

There are also those who advocate the adoption of US military norms, and these people advocate that the US military norms lie in the fact that the US military's military engine is the most powerful in the world, and that if we want to learn from it, we must naturally learn from the most advanced experience, and now that relations between the Republic and the United States have thawed, it is not impossible to introduce US military norms.

In the end, they advocated the use of British norms, and the reason for these people is simple, that is, they value the British norms, and now the Republic has tried to use them in the introduction of turbofan nine, and they have found that it is feasible to have experience, and Wu Lao is one of the representatives.

Now the above is still arguing about which way to go, and there are already research institutes below that have privately begun to engage in British norms, which naturally attracted the attention of the above, and only then did the investigation team have a line, the purpose of which is to investigate the development process of the new engine.

If it is feasible, then there is no need to argue, it must be to take the British route, the first mark of the republic in the last life to go all the way to the debate, the final victory is the American faction, so in 87 promulgated the "GJB241-87 "Aviation Turbojet and Turbofan Engine General Specification"

This norm directly overturns the original military norms of the Republic from the foundation and completely falls to the US standard, which also gives rise to the saying that 'rabbits are the biggest cents'. (To be continued.) )
