After determining the direction, Li Zhong and Wang Xiaodong did not stop, and immediately returned to the casting workshop and began to study the investment casting process.

Chen Yaoyang also volunteered to join the research of this process, and it didn't take long for the investment casting process of Baiyun Factory to make a breakthrough.

Bai Yi didn't participate too much in this regard, as the so-called master led the door, and the practice was personal, he just mentioned that the future development of the foundry workshop was promising, so that Li Zhong and Wang Xiaodong and others had a clear direction of progress.

But this is enough for Chen Yaoyang and Wang Xiaodong and others.

However, this was a great problem for the chief of armaments, who had just returned to the capital from the Korean battlefield.

Since the head of the General Logistics Department obtained the planning drawings and physical samples of the RD-9 engine from the Soviet Union, he organized relevant domestic experts to start preliminary imitation work.

Later, due to the adjustment of work, the chief of armaments mainly focused on the production of military industry, and made great efforts to imitate this important equipment that has a bearing on the future.

Therefore, the chief of armaments not only gathered experts in relevant fields from all over the country, but also gathered all aviation experts who had returned from overseas to form an aviation power research laboratory, which was specially responsible for the imitation of the RD-9 engine.

It is a pity that, except for the slight progress in drawing drawings, everything else has almost come to a standstill, especially in terms of specific manufacturing, which has caused a headache for the chief of armaments who has just taken over the production of the military industry.

"Professor Fu, isn't there a way?"

In the office that is not large, there are a few simple chairs, and the neat floor and icons hanging on the wall make this office look solemn and silent, but it can't stop the indescribable oppressive atmosphere at this moment, just like the gloomy face of the head of armaments, who has nowhere to vent and can only take a few puffs of cigarette in his hand

However, compared with it, Professor Fu's elegant and white face sitting on the other side of the desk was even more terrifying, and he was extremely disgusted with tobacco, but at this moment, in the face of the heavy smell of tobacco wafting over, as if he hadn't heard it, he sighed again and again, and inhaled the smoke into his lungs.

If these American scholars who are familiar with Professor Fu see it, they will definitely drop their jaws, and they will never think that this cow who once quarreled with the director of MIT's aeronautical propulsion laboratory for three days because of the smell of smoke would take the initiative to inhale second-hand smoke, which is unbelievable.

But now the unthinkable is happening in this humble office.

"If there is no foreign aid, we are on our own...... Theoretically...... It's really slim. With the strong smell of tobacco, Professor Fu sighed again.

When the chief of armaments sitting opposite heard this, his face couldn't help but darken a little.

Foreign aid, the head of armaments dreams of foreign aid, but needless to say, Western countries are still fighting with the volunteer army in North Korea, and it would be good for you not to blockade, so maybe it can still help you?

As for the Soviet Union, it sounds good, but life or death is not to come up with something substantial, there is no way who let it be a jet aircraft engine, although it is not a nuclear ~~ weapon like the country's heavy weapon, but it is also the core lifeblood of a country, otherwise how can it be called the jewel in the crown of industry.

After taking two more puffs of cigarette, the head of armaments suddenly remembered something, raised his head and asked, "Isn't that German-made precision forging machine sent by Baiyun Factory good?" ”

"That equipment is barely enough to process ordinary forgings, but the problem is that we are making the turbine blades of jet engines, which need to withstand high temperatures, high pressures and high speeds, so the aging precision forging machine simply cannot meet our requirements."

Professor Fu was also helpless, when he just got the German original precision forging machine from Baiyun Factory, Professor Fu was really happy for several days, and when the equipment was transported to the supporting plant, it was even more precious.

You must know that the precision forging equipment he used during his time in the United States is also imitated from German products, so Professor Fu is still looking forward to this set of precision forging machines.

But contrary to expectations, when the first batch of turbine blades off the assembly line was sent to the laboratory for basic force testing, it was found that all the products were unqualified, and it was later found that the original set of precision forging machines lacked basic care and maintenance because they had been idle in the Soviet Union for too long.

The precision forging capacity has long been reduced, and even if it is repaired with the encouragement of German experts, it still cannot meet the standard of precision forging turbine blades.

As a result, the imitation work that had just begun to emerge came to an abrupt end.

"If it really doesn't work, I'll think of a way, there will be a delegation going to the Soviet Union in two days, and I'm asking those old guys to mention to the Soviet comrades that we can't fight this war, they are bleeding, they are enjoying peace in the back, how can there be such a good thing in the world."

As he spoke, the head of armaments snuffed out the burned cigarette butt in the ashtray in front of him, and his eyes became firm, in fact, he was ready for marathon negotiations with the Soviet Union, even if he did not hesitate to go out in person in the end.

As if seeing the determination of the head of armaments, Professor Fu frowned and said with some concern: "This kind of manufacturing process is the core of any country, and I am afraid that the Soviet Union will not ignore our request at all." ”

"If you ignore it, you will grind them out, the Long March of the year has come over, can't they be consumed at the face-to-face negotiation table? It's a joke, the people who come over the snowy mountains and meadows, how can they kill them. ”

The head of armaments said these words in an unquestionable tone, and Professor Fu wanted to say something more, but was interrupted by the chief of armaments raising his hand: "I know what you mean, there is no need to put all your face in it for such a difficult bone, but what I want to say is that in order for this newly established country to no longer suffer, and for his territory not to be violated, not to mention the face of us old things, even if this old life is not worth it...... Do you know what I mean? ”

These words were like a thunderclap on the ground, which made Professor Fu feel a little moved, and he only felt that it was definitely the right choice for him to work hard and break through many obstacles to return to this country that was in ruins, because his wishes coincided with those in power.

So Professor Fu nodded heavily, and just wanted to say something, the phone on the table rang suddenly, and the head of armaments frowned and picked it up, just listening to one sentence, the peaceful eyes widened violently, and immediately bounced up from the seat, and the voice suddenly rose a few points, and shouted: "You repeat, Baiyun Factory made turbine blades?" ”
