Seeing that his old buddy An Zhusheng was studying Shen Yiyi's engine drawings with his apprentices and grandchildren, Xiao Yizhan was not in a hurry at this time. He sat down firmly and began to taste the tea that the staff of the 606 Institute had filled for him just now, and while tasting the tea, he was able to observe the movements of the people in front of him for a long time.

After a while, as Old Man Xiao expected, An Zhusheng suddenly raised his head and looked at himself: "Old Xiao, this engine actually uses aviation aluminum?" ”

Old Man Xiao nodded very calmly: "That's right, it's aviation aluminum." The first thing he noticed was the material in the lower right corner of the drawing. The combination of English and numbers above is very similar to the aircraft profiles he knew.

An Zhusheng was a little incredulous: "How is it possible?" You should know it, I saw it from the bulletin in the system, this material was just last month from the material institute sent to you the new material list of the body structure, how can someone actually use it in the engine? Structural aluminum alloy profiles are well known to be not resistant to high temperatures, isn't it? How could anyone use an engine? Does this person not understand or does he really have a discovery? ”

Old Man Xiao nodded: "Yes, there is no high temperature index requirement for alloys used in ordinary body structures, so judging from our previous experience, I would not have thought of applying it to the engine for materials composed of elements of this family." But before I came, I made a special call to the physical and chemical properties room of our factory, do you know what I found? ”

Old Man Xiao deliberately sold a pass, and An Zhusheng really couldn't wait, and asked anxiously: "What did you find?" ”

"As early as five years ago, the Institute of Materials only did room temperature physical properties for providing our body materials, not high temperature physical properties." After the old man Xiao Yizhan told the fact he had learned, he saw his old man's big mouth with satisfaction. Indeed, this fact was first heard. He himself was surprised.

The Institute of Materials, as the name suggests, specializes in the study of materials. They study the combination of various elements in various processes and compositions to form new materials, and then test their mechanical, electrical and chemical properties in various use environments, and then compile these data into a catalog and send them to various units where they can be used. For these units to choose from when designing and manufacturing their own equipment. It can be said that if each unit encounters a bottleneck in manufacturing, that is, an unavoidable problem, one of the solutions is to look through the material catalog to see if it is possible to find a new material to achieve the same performance, but with better processing performance. If the material does not give the designer the parameters he wants, then the designer will not be able to discover new uses for the material.

"How can they do this?! This is extremely irresponsible in work, a child's play on the cause of the party and the state, and even more irresponsible to the people! Old man An Zhusheng was furious. He has been rigorous in his studies all his life. What I can't tolerate in my eyes is this kind of child's play attitude towards scientific research. It was an unforgivable mistake in his opinion that the Institute of Materials did not conduct a thorough test of the newly developed material in accordance with the regulations.

Old Man Xiao nodded: "Yes, I was just as angry as you when I first heard it." But if you look at it further, you will know that people also have difficulties. ”

"What's the problem? They are not qualified to excuse themselves for not doing their job properly, and you should not help them shirk their responsibilities. I want to report this matter and find a higher authority to give them a good rectification! An Zhusheng was still very angry. Just think about these five years. He was extremely angry that the Institute of Materials had not tested the high-temperature characteristics of the newly developed materials. Know the way. Over the years, they have not been able to produce results in these engines, because there is no new durable material born. He originally thought that this was our country's weak foundation and poor foundation, so for the sake of the same scientific research community, he was very considerate of them. But now he was told. Those who worked on the materials actually cut corners and perfunctory to their work, which made him feel cheated all of a sudden.

"I advise you not to report it." The old man Xiao Yizhan poured cold water on the angry old man An Zhusheng.

"For what? I said, Lao Xiao, aren't you just as jealous and hateful? Why are you starting to be a collaborator and a sludge again? An Zhusheng has a lot of opinions about Xiao Yizhan's failure to stand resolutely with him in this matter.

Old Man Xiao mentioned another thing: "Lao An, do you remember the accident that occurred during your engine test five years ago?" At that time, you had to test the extreme performance of the blade on your engine, forcing the material institute to raise the temperature of the test machine to a very high level. The last thing to break the leaves, right? ”

An Zhusheng didn't expect the old guy to suddenly mention this matter, he was a little stunned, and then nodded unnaturally. Indeed, the thrust of an engine they were developing at that time could not go up, and he returned to the method of increasing the initial temperature of the gas when almost all the methods were unsuccessful. However, although this method is effective, it has extremely high requirements for the performance of the blade material. At that time, there was no opposition in the project team, and it was very big, and they all told him that they should either determine the indicators based on the thrust performance that could actually be achieved at that time, end the project first, and then find a way to improve and improve it later. In this way, everyone can get by and the project can be completed. But An Zhusheng didn't do it, his idea was very simple, if the performance of the engine was not greatly improved, what would the country do with so much money to develop a new engine? If so many manpower and material resources are invested, the final result is just another engine with similar capabilities, and it is irresponsible for the people to do such simple and repetitive work. At his insistence, in the end, he almost single-handedly pushed the plan to increase the initial temperature through. However, in the material test before the test, the leaf he took for the high-temperature physical property test broke in the dynamic test, which also declared his plan stillborn. Later, the engine project he was working on was halted because of this failure, and then the project was never restarted due to political turmoil.

Memories are a little bitter, so An Zhusheng has been trying not to recall this time before being reminded of this failure. It can be said that this trial was one of the biggest setbacks of his life. Now that he was asked by Old Man Xiao, he could only be honest: "Yes." The test was a mistake on my part, because I saw the chaotic situation in the country, and I was afraid that if I didn't produce results as soon as possible, the progress of the entire research would be affected. Unfortunately, the test failed, and the project was canceled. ”

Old Man Xiao said solemnly: "It's not just this result, do you know the way, just because you insisted on the test, but you didn't make a plan for the failure of the test in advance, the result was that your blade was broken, and at the same time, the debris that flew out also damaged the high-temperature test machine of the other people's materials." ”

"What? It's true? When An Zhusheng heard the news for the first time, it was a little incredible. He knew the importance of the test machine to the material. The equipment imported from the former West Germany was the first batch of equipment imported after the reform and opening up, and at that time it accounted for almost a considerable part of the country's meagre foreign exchange reserves. After the introduction of the Institute of Materials, other scientific research units were very envious, and the Institute of Materials was also very proud. "Wouldn't it? Why haven't you heard from them? ”

"Can't believe it, huh? The truth is that after your failed experiment, the political turmoil brought scientific research activities across the country to a virtual standstill. So, after your test stopped, there was almost two years after the test was stopped, and no one noticed that the device was damaged during that time. Talking about the political turmoil in the late 80s, the two old men couldn't help but recall the chaos that plunged most of the country's cities into anarchy, and their hearts were very heavy.

An Zhusheng sighed and said, "Alas, after all, those young students are too impulsive. They are completely unaware of how much damage their actions will cause to the country and society, and they think that they are the people who can best save the country and the people, and they are naively used by hostile forces, and as a result, they have caused so much damage to the country and the people. After a pause, he said, "How did you find out about it?" How can I say that it was damaged because of my test? ”

Two years later, various scientific research was on the right track, and the Institute of Materials also thought that it should return to the road of continuous development of new materials, so the instrument for the physical properties test of this high-temperature material was overhauled and maintained, but suddenly found a failure. Because the warranty period has long passed, I want to ask the original factory to help repair it. However, at that time, the country was facing Western sanctions, and it was impossible to invite someone to repair it. Therefore, the material is carefully disassembled after the machine, and then the original is reset. During the disassembly process, a fragment was found in the middle of the thermostat and the sensor, and the material was the same material as the blade you tested at that time. Therefore, it is reasonable to infer that the failure of your test test also broke the test machine of the material institute. ”

An Zhusheng nodded. In fact, he had already accepted the statement that his test had damaged the machine of other people's materials, but he just wanted to know the cause and effect of the road. He then asked, "Then why didn't they tell me that we should pay them?" ”

Old Man Xiao smiled: "Are you deliberately pretending to be stupid?" They only discovered this damage two years later, isn't this not the mismanagement of important instruments and equipment in their office? And even if you cause damage, the two-year effective prosecution period has passed, and you can't win the lawsuit, and it is possible for their leaders to get a punishment, how can you say that the material institute will come to you again? ”

"But since then, in the catalog of new materials sent by the material, the data of the high-temperature test is no longer provided, you say, how can you report this matter?" At the end, Old Man Xiao asked An Zhusheng rhetorically. (To be continued......)
