In this way, under the leadership of Hu Qinghua, the reform of the Wanshan plant was gradually and gradually advanced in a way that moisturized things and silently, and Lu Jiadong was only optimistic about the success of the work, and did not intervene too much, because he had already finished his vacation, and he had already begun to turn his energies to the development of new tanks again; just a few days after Lu Jiadong was resting, the MB870Ka-500 engine prototype assembled by a certain Chinese diesel engine factory with spare parts provided by the American Gage Xinda Company had arrived at the equipment test center of the Wanshan plant.

This is a core power system related to the future of China's tank armored vehicles, so when he heard that the MB870Ka-500 engine prototype was in place, Lu Jiadong immediately ended his vacation and immediately drove to the equipment test center of Wanshan Factory to prepare for a thorough test of this German diesel power system from the United States to see how the performance of this power system is and whether it matches the new tank.

After a long preparatory process, the MB870Ka-500 engine prototype was hoisted onto the newly set up power system test bench, and the staff was carrying out intense inspection work, and the entire test site entered a tense state as if it was about to fight.

What's more, this power system is assembled by China, although all the spare parts are provided by the American Gage Cinda company, but the assembly of the engine is not a child building blocks, according to the drawings on the line, but a meticulous work no less than technological innovation.

Take the sealed piston of the engine cylinder, for example, it seems simple, but it requires extremely precise assembly technology to install it, in Germany and the United States, high-precision assembly machine tools are used, but there is no such equipment in China today. Therefore, it can only be assembled by manual fitters, in order to reduce errors, an engine factory specially organizes the most experienced fitters in the factory to tackle key problems.

In the end, a proper assembly plan was formed, but no matter how good the craftsmanship of the fitters of the factory was, there would eventually be mistakes and errors. If you are not careful, the rated power of the engine will not meet the technical requirements, and the entire engine may be scrapped, otherwise the Wanshan Equipment Test Site will not be so nervous.

In any case, the self-assembled MB870Ka-500 engine prototype is still of great significance, you must know that this is an important step in the localization of the power system, so including Xu Yuan, Lu Jiadong, Zhu Guangrong, Wu Tianming and others can be said to be all present, which makes the newly established power test room very lively, it is conceivable that with the future progress of China in the diesel power system. It's going to be busier and more lively, like the big red sign on the wall of the testing chamber:

"Tackling difficulties and resolutely fighting the key battle of new power system commissioning"

It is estimated that it will hang forever in the future, because the road ahead is really long

A huge roar sounded, and the prototype of the MB870Ka-500 engine assembled by China entered the test stage for the first time. After the first run-in test, the MB870Ka-500 engine was normal and entered the "factory test". 2000 rpm, 3000 rpm, 4000 rpm, 5000 rpm

These engine revolutions are read out by the tester close to the data on the instruments that are being arranged in the engine being worked. At the same time, other staff should also keep an eye on their own related equipment, check the oil supply system, cooling system, acceleration system, cylinder situation, and air tightness. After repeated verification with theoretical data, the final result can be obtained.

Lu Jiadong stared at the data on the comprehensive data display in the general control room, frowned, and calmly gave instructions against the standard data sample of the MB870Ka-500 engine in his hand:

"The rated speed is not enough, readjust, no. Adjust Again"

"The maximum temperature difference is readjusted, right, right, adjusted again, increase the power"

After many commissionings. Everything is the same as the original MB870Ka-500 engine technical data, the data displayed by the instrumentation, the engine performance is preliminarily determined to be good. This is followed by a long 200-hour model, and if nothing else, there should be no big problem, which means that the MB870Ka-500 engine assembled by China can be said to be a complete success. Suddenly, applause and cheers accompanied by the huge roar of the engine resounded inside and outside the test bench:

"It seems that the quality of our self-assembled MB870Ka-500 engine is still very good!"

"That's right, the next step is to gradually expand localization, so that our tanks completely have a Chinese heart!"

"That's right, to be honest, this MB870Ka-500 engine is indeed much better than the Soviet Union's B series diesel engine, with a maximum power of more than 1,000 horsepower.

After Xu Yuan and others watched the test, they left the power system test room with joy, and while walking, they happily talked about this MB870Ka-500 engine, and cheerful laughter came out from time to time among several people, but Xu Yuan, who was walking in the front, noticed that Lu Jiadong, the executive chief designer of the new tank, had not spoken, and couldn't help asking:

"Xiao Lu, what do you think?"

"This" At this time, Lu Jiadong was thinking about the future development plan of the new tank, and when Xu Yuan asked him this, he couldn't help but be stunned, but then reacted and shook his head slightly:

"I think it's okay!"

"Well, where did Zhu Lao go?" Xu Yuan knew that Lu Jiadong had always been rigorous and meticulous in the technical field, so he didn't care when he heard his answer, and his eyes skimmed over Lu Jiadong's body, but after looking for it, he never found the elderly figure beside him, so he had no choice but to turn around, but just as he was about to speak, he saw Zhu Guangrong's face a little pale, covering his lower abdomen by himself, and following behind with a staggering step:

"Zhu Lao, you are"

Listening to Xu Yuan's anxious voice. Only then did everyone react, and they quickly turned around, only to find that Zhu Guangrong was indeed a little wrong, in fact, a little careful saw the clues in the previous test, because at that time Zhu Guangrong was always frowning, and his face was not very good. It's just that everyone was very nervous at that time, so they didn't care, but at this time, they frightened everyone, Zhu Guangrong was like being drunk, and he couldn't help but have difficulty walking, and beads of sweat the size of beans crackled down from his forehead:

"I wish you what it is?"

Lu Jiadong hurriedly ran to Zhu Guangrong's side, picked him up, and asked Zhu Guangrong anxiously. But at this time, Zhu Guangrong was so painful that he couldn't even speak, in fact, he felt some pain in his abdomen these days, and this morning he felt even more weak, abdominal pain and vomiting, but today is the day of the MB870Ka-500 engine test, such a major matter, he must persist no matter what, in order to grasp the first-hand information. In order to prepare for the subsequent advancement of the new tank, it is necessary to insist on going to the test site no matter what.

His personal secretary saw that he had a bad face. Before leaving, Zhu Guangrong had been persuaded to go back to rest several times, but he never refused, and when he watched the actual test of the engine in the test workshop, Zhu Guangrong was indeed a little unbearable, so he gritted his teeth and held on to the back of the chair.

Lu Jiadong's face turned pale when he saw Zhu Guangrong. Cold sweat was dripping on his forehead, and he hurriedly shouted at the staff around him: "Hurry, prepare the car quickly"

Zhu Guangrong was soon taken by vehicle to the nearby Sanlin City People's Hospital, where he was examined by a doctor and diagnosed with acute appendicitis perforation. This makes everyone breathe a sigh of relief, you must know that Zhu Guangrong has had many years of old stomach disease, once it worsens, the consequences are unimaginable, fortunately it is appendicitis, at least it will not be life-threatening, the director of surgery of the People's Hospital personally operated on Zhu Guangrong, and he could not eat after the operation, relying on intravenous drips, and the doctor allowed him to eat two days later, so he arranged for someone to stew chicken soup and send it to Zhu Guangrong.

Zhu Guangrong on the third day after surgery, his youngest daughter who worked in Yangcheng came, Zhu Guangrong has a total of three children, Zhu Lei is his youngest daughter, just 24 years old this year, because he has loved literature since childhood, so he chose the profession of journalist, and now he is a reporter of Yang~~City~~Day~~, when she received her father admitted to the hospital due to illness, she put down all the things at hand, and felt Sanlin in a hurry.

When Zhu Lei came, Zhu Guangrong was half-lying on the bed looking at a thick English original book, although Zhu Guangrong knew English, but generally did not read much, but when he was developing a new tank, he found that Lu Jiadong often mentioned a calculation method called finite element, after he went back to try it, he felt that it was indeed much better than the original set of theoretical calculation methods learned from the Soviet Union, so he asked someone to get a few books back to study and study.

During the period of recuperation, he also had nothing to do, so he asked his secretary to bring the original version of "Finite Element Analysis" that Lu Jiadong had just bought from abroad a few days ago, and studied it carefully in his spare time, so when Zhu Lei came in, Zhu Guangrong was reading "Finite Element Analysis".

Zhu Lei's personality is very arrogant, which can be seen from the profession she chooses, if there is no arrogance, it is impossible to choose the profession of journalist, and he is also a filial girl, although he is the eldest in the family, he is inevitably a little pampered since he was a child, but he has never forgotten his kindness to his parents, otherwise he would not have taken the initiative to ask to be transferred to the sheep located in the south ~~city~~day~~The purpose of working as a reporter in a newspaper is simple: to be close to his sick father, so that he can have time to take care of him.

To tell the truth, this time Zhu Guangrong went south to take over the task of developing a new tank, and the Zhu family had reservations, for no other reason, just because Zhu Guangrong's health was really not very good, and the biggest opposition was the youngest daughter Zhu Lei, who only felt that his father had paid enough when he was young, and now that he was old and in poor health, he should enjoy Qingfu at home.

But as the saying goes, the arm can't be twisted into the thigh, although Zhu Guangrong is very fond of this little daughter, and he is also obedient in daily life, but Zhu Guangrong can be said to be a man of his word in terms of military development, so Zhu Lei's opposition is basically ineffective, Zhu Lei saw that he couldn't persuade his father, so he turned his anger on the young man named Lu Jiadong, if he didn't speak in front of his father, how could his favorite father drag his disease-ridden old body to the southwest.

For this reason, Zhu Lei wanted to talk to Lu Jiadong, but first, his father Zhu Guangrong stopped him, and secondly, Lu Jiadong was negotiating with the Americans during that time, involving confidential matters that ordinary people could not access, and later after his father went to Wanshan Factory, the conditions were good in all aspects, so Zhu Lei slowly pressed this thought.

Although her mind pressed, but did not disappear, when she heard the news that her father was sick and hospitalized, and had surgery, the nameless fire hidden in her heart suddenly burst out~~ at once, when Zhu Lei, who was already in an unhappy mood, pushed open the door of the ward and looked at her father like a primary school student still looking at advanced professional books in bed, the anger was even greater:

"Dad, how sick you are, why do you still read books like this?"

"Appendicitis, it's not an old stomach disease, minor surgery, it's okay, it's okay!" Zhu Guangrong couldn't help but be stunned when he saw Zhu Lei coming, but then closed the book and waved his hand indifferently, but Zhu Lei didn't take this matter so lightly, and sat in front of Zhu Guangrong's hospital bed, a pair of arrogant almond eyes suddenly became warm and veined, covered with a thick layer of mist:

"There is a cloud in "Bian Que Sees Cai Huangong", Jun has a disease in his gut, and if he is not treated, he will be afraid, Dad, although you look at this disease, if you don't pay attention, it will inevitably spread and develop, so, Dad, you just listen to me, let's not develop any more tanks and armored vehicles, let's go back and raise them, and strive to live for a few more years, isn't it?"

"Look at you girl, why are you still crying? I'm not good, besides, since I was a child, I didn't teach you sisters a few sisters, there is a country to have a home, tanks, armored vehicles, those are all national weapons, just like the furniture of an ordinary family, if you don't have it, how undecent"

"Dad, I understand everything you say, but there are still so many talents in the country, but I am only your father!"

"Okay, okay, how old are you?" Zhu Guangrong took a handkerchief to help his daughter wipe her tears: "Actually, your father and I are treated very well here, no worse than the north~~~ Beijing, Lu Jiadong, Chief Lu takes care of me."

"Take care?" mentioned Lu Jiadong, Zhu Lei was like a spring that had been touched by the mechanism, and the waist that had originally bent down stood up on her own, and her peachy pink cheeks were instantly frosty:

"That's how he takes care of your father? I've never seen anyone who can take care of a good person on a hospital bed, no, I have to talk to him this time, said"

"Chief Master Lu, are you here so early today?"

"Zhu Lao, are you better?"

Without waiting for Zhu Lei to finish speaking, the conversation outside the ward came in clearly, and when Zhu Lei heard it, a pair of willow eyebrows immediately erected, and then got up and walked towards the door of the ward

"Xiaolei" Zhu Guangrong wanted to stop Zhu Lei, but before he could shout, Zhu Lei had already rushed out of the room (to be continued). )
