"You said that the issue of the company's scale effect and industrial diversification is indeed worth paying attention to, including my connection with various things on Rolls-Royce's side, and I have a deep understanding of this. ”

I happened to have dinner and walked on the way back to the guest house, and I took the opportunity to raise the problems I had encountered in the UK over the years to see if there was an opportunity to solve them when the new company was integrated.

"Take the new generation of civilian mid-promotion development projects that we are now participating in, just because our company is small and not famous, even BMW Aerospace, a guy who has been down for decades, wants to come up and step on two feet, why should it?"

BMW during World War II was indeed very showy, and the planes and engines produced were all awesome, but now it is different, and after being sanctioned for decades, it still wants to press on the head of a company like Southwest Motive, which has its own products, has a certain system behind it, and is supported by the market, which is indeed .....

If you want to ask what the real reason is, in the final analysis, it is still ignorance!

BMW Aerospace does not know the strength of Southwest Motor, and Southwest Motion itself has no customers and influence abroad, so it will be despised, now since there is an opportunity to make the company bigger, as long as the technology of a complete set of power equipment is reasonable, it is no problem to participate in foreign competition and play a certain popularity.

"BMW Aerospace is really a bit of an old Junkers aristocratic temperament, it's okay, heh! What is the current situation, the project can still go smoothly, right?" Wang Zhengguo smiled.

And if it's just to move forward with the project, it's not that difficult.

The cooperation project between Southwest Motor, BMW Aerospace and Rolls-Royce is completely different from the cooperation between Southwest Motor, Oriental Complete and Gas Turbine Institute.

As one of the three giants of aero engines, Rolls-Royce is fully qualified and capable to ensure the smooth progress of the project, and its reputation and experience are the key to the other two younger brothers.

"It's all been solved, Xiang Qiao is doing the final standard docking over there, if there is no problem, when he comes back at the end of the year, he can take our own designers to start the relevant design work, we don't undertake the development of the core machine, so it's not a big problem." As for BMW Aerospace, they are all doing the development of fixed accessories, which is less difficult, if it were not for the loan support of the German government, we and Rolls-Royce would have been able to do it. ”

BMW is indeed a good hand at making automobiles now, but it is difficult to say that it is engaged in aviation manufacturing!

"By the way, speaking of the 624 Institute, it seems that they are more experienced in the basic design of turbomachinery, in order to be able to do the best of our part of the task, so it is best to cooperate with them to do the development at that time, after all, we are all peers in the southwest, and we should support each other. ”

Strictly speaking, the 624 Institute is specialized in the development of core engines, test engine units, and now is undertaking the promotion of high-push pre-research projects, they have a set of compressor design, combined with these technical forces, can definitely successfully complete the low-pressure rotor development task undertaken by Southwest Motor.

The opinion from Chief Engineer Wu Daguan is indeed very reasonable, Wang Zhengguo doesn't even need to think too much, just nod his head in agreement.

"It just so happens that now we want to cooperate with the 624 Institute, which is nothing more than deepening the combination, I support it!"

......

"The last question, I thought about it for a long time, but I still feel that it is necessary to bring it up, although it conflicts with the gas-steaming combined cycle technology proposed by Director Wu Zhonghua before, but in terms of the development trend of gas turbines that I have seen in Europe and the United States in recent years, I am afraid that we need to change the technical route. ”

Director Wu Zhonghua had just fallen ill, and after the handover of the work was completed, Chief Engineer Wu Daguan, who took over the project here, immediately overturned the technical route set by the former, which sounded a little chilling.

But Chief Engineer Wu Daguan still chose to put it forward at this time, so this may be really a bit debatable, is there a better technical route?

"Abandon the combined cycle of combustion and steaming, then the chief engineer, what do you mean to go, you must know that the thermal efficiency that can be improved by this route is already considerable, and the loss caused by giving up it is definitely not easy to make up. ”

With a chuckle, he slowly told his opinion.

"Of course, I know that the thermal efficiency of the scheme proposed by Director Wu is almost more than double that of the simple cycle, and it has reached more than 50% in this regard in the world, but the technical scheme has a very big disadvantage: boiler water. ”

The combined cycle of combustion and steaming, which naturally requires the use of boilers, can only be used as a medium to drive the operation of steam turbines after the water vapor is burned, and if you want to talk about such things as boilers, it is indeed quite troublesome in terms of maintenance.

This also reminded Wang Zhengguo of an old news he saw on the forum about the water problem of steam turbine boilers used in warships.

In the summer of 1978, the "Yuanwang" survey ship entered the dock test stage, and found that the distilled water quality hardness of the boiler was high.

Later, in order to ensure the quality of the project, the factory leaders decided to "tear down and start over", formed 4 "sharp knife squads", braved the scorching heat, entered the low cabin to assault the shovel, until the water tank shovel came out of the white, and then re-painted. After water injection testing, the water quality reached the technical requirements.

The boiler water tank is stored as ordinary water (drinking fresh water), and the storage conditions are not up to standard, which shows that the boiler water standard is high, and if it is really used in distributed gas-fired power generation equipment, there are indeed huge loopholes in logistics maintenance.

In essence, boiler water has always been specially treated soft water, even if human drinking fresh water can not be satisfied, if this kind of thing is really used, it will not be long before the boiler and steam pipe inner wall will be formed with a thick layer of scale, which is simply a disaster for boiler use.

The hazards caused by boiler fouling are that the output vapor pressure of the boiler is insufficient, and the high-pressure steam generated by the boiler cannot be discharged in time, resulting in the boiler explosion.

Of course, even if soft water is used as the steam generation medium, there is no guarantee that there will be no scale at all, but the amount of scale can be controlled and can be treated until the ship is overhauled.
