Siheyuan: Originally I just wanted to be a little transparent

Chapter 324 If you can’t figure it out, please ask for help.
Seeing that this was the case, Lin Shengli continued: "I agree with the theory that it was a fuel leak that caused the engine to explode."

"However, have you ever thought about it? This reason is probably just a performance reason."

When Lin Shengli said this, everyone's eyes widened and their ears pricked up, waiting for Lin Shengli's next words.

"Everyone has seen the data of the entire test process. Before the engine exploded, the pressure inside the propulsion chamber became smaller and the data was abnormal. This illustrates a problem."

"If there had been a fuel leak at that time, according to common sense, the pressure inside the propulsion chamber should have increased due to the violent combustion, and it should not have decreased."

After Lin Shengli said these words, someone immediately figured out the key to the problem, so someone stood up and said:
"Counselor Lin, if we think according to what you said, it should be that the internal structure of the propulsion room has been damaged. No, no, it should be damaged. Otherwise, this pressure will not happen for no reason. Get smaller.”

Lin Shengli glanced at the researcher who spoke, nodded, and continued: "Yes, from the above analysis, I think it was the internal structure of the propulsion chamber that was damaged, which caused the pressure to leak."

"So, we found out the first problem."

"Before the engine exploded, the reason why the internal pressure of the propulsion chamber became smaller was that the internal structure of the propulsion chamber was damaged when it was working."

"Next, let's analyze the second question. When did the engine explode?"

"The reason for this problem, and I agree with what the first two comrades who spoke just now said, is the problem of the cooling equipment."

"When the engine is working, the temperature inside the propulsion chamber will rise sharply. The abnormally high temperature will cause problems in the fuel supply system, causing fuel leakage, and then triggering an explosion."

"Then, combining these two analysis results, it is not difficult to find the culprit that caused the internal damage to the propulsion chamber, and that is its nozzle."

Everyone present at the meeting was very surprised and confused after hearing the conclusion analyzed by Lin Shengli.

In the past few days, everyone has thought about many aspects that could have caused the explosion, but no one has thought about the nozzle.

Lin Shengli glanced at the people whispering below, smiled and said: "You may be a little confused, why do I say that the culprit of this explosion is this nozzle?"

"Yes, Consultant Lin, this nozzle is at the very back of the entire engine. Logically speaking, even if there is a problem with it, it will not affect the entire engine, right?"

This researcher’s question is also a question that everyone here wants to know.

Lin Shengli waved his hand and motioned for the researcher to sit down first, and then he continued: "You might as well think about it, after the accident, when everyone was searching for engine fragments with all their strength, who found the nozzle fragments? "

"I heard from our comrades that at that time, even comrades from the fire rescue department joined the search team."

"I believe that with everyone's serious and rigorous attitude, the search work for the entire area covered by the explosion should be almost three feet deep. There will definitely not be any missed areas."

After listening to Lin Shengli's words, everyone suddenly realized.

This is indeed the case. Most of the targets of everyone's research and analysis are placed on the propulsion chamber, but they ignore the nozzle at the bottom.

"Our comrades have searched so carefully for the debris after the engine explosion, but they have not found any fragments of the nozzle. So, this can only mean that the nozzle has long melted due to the high temperature when the engine was working."

"It was precisely because the nozzle had problems first that it caused problems with the internal mechanism of the propulsion chamber, which in turn led to pressure leakage."

"Of course, these analyzes and opinions are just my personal opinions."

"If you have any other opinions, we can continue to discuss it."

After Lin Shengli finished speaking, he picked up the teacup on the table and took a sip.

As Lin Shengli finished speaking, everyone at the meeting began to discuss.

It didn't take long for everyone present to reach a consensus.

Everyone agreed that the engine explosion accident was caused by pressure leakage due to damage to the nozzle. After the propulsion chamber structure was damaged, there was a problem with the fuel supply system, and then the fuel leaked, which in turn caused the explosion.

After seeing that no one had any other opinions on this conclusion, Lin Shengli raised another question.

"Okay, now that everyone agrees with this conclusion, there is only one last question left, which is this nozzle. Why is it damaged?"

After Lin Shengli finished speaking, Worker Lu stood up and said: "Counselor Lin, comrades, I think there is a problem with the material of this nozzle. It is not resistant to high temperatures at all."

"As Consultant Lin analyzed just now, after the explosion, we didn't even find a fragment of the nozzle. That can only mean that the nozzle must have been melted by the high temperature."

Lu Gong's conclusion was unanimously recognized by everyone.

After seeing that everyone had unified their opinions, Lin Shengli said to Team Leader Wang who was sitting in the back:

"Team Leader Wang, now that the cause of the accident has been found, I will leave it to you to solve the problem later."

"You have to report to the superiors that a new high-temperature-resistant material must be found. This material must be able to withstand temperatures above 3000 degrees."

After hearing what Lin Shengli said, Team Leader Wang nodded.

He really has to talk about this matter. He is the specific person in charge of this project and the big steward of the entire project.

Immediately, Team Leader Wang left the conference room without any delay and hurried to contact his superiors.Team Leader Wang's report was reported, and Lin Shengli also ended his work at the Gan Province base and returned to Sijiu City.

After returning to Sijiu City, Lin Shengli learned from Yan Bugui, the second uncle, that Bang Gang was sentenced to one year of labor reform in a juvenile detention center.

Lin Shengli didn't express any opinion on this matter. After all, it's not unusual for someone who was brought up by a family like the Jia family to do any nonsense.

However, Lin Shengli was impressed by Wang Erni's handling of the matter and silently praised her in his heart.

Team Leader Wang's report soon reached the hands of Dean Qian.

Looking at the requirements in the report in his hand, Dean Qian also smiled bitterly. Materials that can withstand temperatures above 3000 degrees are really difficult to handle.

There is nothing you can do. If you can't handle it on your own, ask your superiors for help.

The superiors also had a headache when they saw the report brought by Dean Qian.

Fortunately, the superiors had a way to mobilize the masses and sent letters of investigation to all units and departments related to steel materials.

Soon, this method of finding a needle in a haystack actually found it.

That kind of high-temperature resistant material was found in a steel factory in the northeast.

This kind of high-temperature-resistant material was developed when Mao Xiong assisted in construction.

Because it was done relatively early, by the time the Mao Xiong evacuated, this material was almost ready.

However, due to certain reasons in this era, that material has never been accepted and used.

Now, if you want to use this material, Team Leader Wang and the people on the project must personally inspect and accept the material.

And for this job, whether it was due to the need to keep the project confidential or the convenience of work, there seemed to be no one more suitable than Lin Shengli.

Because that steel plant is itself a subsidiary of the Ministry of Metallurgy, and Lin Shengli, in addition to being the plant leader of the Red Star Rolling Mill, is also a second-level researcher of the Ministry of Metallurgy.

When Lin Shengli was renovating the rolling mill, that steel plant was one of the factories that sent people to study. It could be said that Lin Shengli had a teacher-student relationship.

Furthermore, no one knew that Lin Shengli was involved in the launch vehicle research and development project, except for his superiors and those working on the project itself.

Lin Shengli, who is apparently a researcher in the metallurgical department, a developer of rolling mill modifications, and a teacher at the steel plant, used to inspect and accept their material project, which was very reasonable and made communication easier at work. Not to mention, there was no one. Think of where this material will eventually be used.

Just like that, Lin Shengli, who had just returned, received a new task, going to the steel plant in the northeast to inspect and accept the high-temperature resistant material.

This time back to the Northeast, because Lin Shengli went to inspect the project in the name of being dispatched by the Ministry of Metallurgy, so he would not have to take a military plane as quickly as he went to the base in Gansu Province, but would have to take a train. past.

In order not to attract too much attention, but also for the sake of Lin Shengli's safety.

In addition to Lin Shengli taking Master Wu as his personal guard, his superiors also dispatched two security personnel to accompany Lin Shengli in the name of attachés of the Ministry of Metallurgy.

The next day after receiving the notice from his superiors, Lin Shengli simply packed his luggage, took a few security personnel, and boarded the train to the Northeast.

The place where Lin Shengli went was known as the old industrial base in later generations, but in this day and age, it is the big brother who is serious about domestic industry.

In fact, during the war years, Northeast China had a fairly strong industrial base.

Later, after the new flower grower was established, relying on the industrial base here, and the fact that it was relatively close to Maoxiong, when Maoxiong assisted us in construction, a large number of various factories were built in the Northeast.

Naturally, this place became an industrial center for flower growers.

After getting off the bus, Lin Shengli and others did not delay and went directly to the destination of their trip, Shen City Steel Plant in Liaoning Province, referred to as Shen Steel.

This Shenyang Iron & Steel Co., Ltd. is said to have been founded in 1948. During the period of technical assistance from Mao Xiong, it was renovated and upgraded, and it became one of the top steel companies in China during this period.

The level of this enterprise has already been the same as that of the upgraded Red Star Steel Rolling Mill.

"Hello, comrade, we are here from the Metallurgical Department. We are looking for Factory Director Zhao. This is our letter of introduction."

Lin Shengli and the others arrived at the entrance of Shenyang Iron & Steel Co., Ltd., and the accompanying staff said to the comrades in the reception room at the entrance.

Seeing that Lin Shengli and the others took out a letter of introduction, which was sent by their superior Metallurgical Department, the person in charge of the reception room at the door did not dare to delay and said quickly:
"Comrade, please wait a moment, I will contact Director Zhao for you right now.

After saying that, he ran back to the communication room and contacted the factory by phone. "

Not long after, a young man appeared at the gate.

He walked quickly to Lin Shengli and the others and said, "Hello, comrades, are you comrades sent by the Ministry of Metallurgy?"

"I am Director Zhao's secretary. You can call me Xiao Liu. Director Zhao asked me to come and pick you up."
