Shen Huan smiled bitterly and said: "Director Zhao, I'm still very confused, how could I join such an important and expert-filled military technical delegation, with my qualifications, I am really not qualified!"
” Zhao Jinfu laughed and said, "Didn't I already say it just now?
It wasn't you who came, it was a temporary change that made you here.
You don't have to be afraid, I see that the last time you were at the meeting to solicit opinions on a new type of missile destroyer, you were really bold, and I was shocked by this old guy who has been engaged in warship design for decades.
Do you know?
Your suggestions have basically been adopted.
So this time, on behalf of the construction unit, it is logical for you to visit with the group, and there is no qualification!
” Wang Dalu, the tank chief engineer on the side, couldn't help but smile and said: "Director Zhao is too right, I think Comrade Shen Huan is young, but he is much stronger than us old guys."
I heard that Director Zhao slapped the table with many people in order to modify the design!
” Zhao Jinfu nodded and said, "It's not!"
Comrade Shen Huan's suggestion is indeed to make the old man and me pause, and we should be bold if we can take fewer detours!
” Shen Huan couldn't help but feel a little embarrassed when he heard this, in front of these real expert masters, that is, a person who seemed to know a lot, but in fact only had the advantage of rebirth, he could know the future development of weapons and equipment, and if he wanted to design it, he would be exposed.
Shen Huan thought for a while and said, "Director Zhao, this time we go to Wukeland, is the main task to negotiate the introduction of ship gas turbines?"
” Zhao Jinfu nodded and said: "Yes, now we don't have the power to install a ship, there is no engine available, and our new missile destroyer can only stay on the drawings."
Now the only thing that can be bought is the DA80 gas turbine of Vukland, although the performance of this gas turbine is much behind that of the United States, but it is the only choice for the new missile destroyer, and the heart disease problem of our warship cannot be solved for a while!
Alas!
” Zhao Jinfu sighed, for a warship chief engineer, without a good power plant, the performance of the warship will be greatly reduced, and now there is only the introduction of this gas turbine from Vulkland to solve the urgent need, otherwise the new missile destroyer does not know how long it will lie on the drawings!
If it weren't for the fact that many of Ukland's military-industrial enterprises would not be able to eat, how could China have such an opportunity to pick up treasures and dig into corners?
In Shen Huan's memory, Jiangnan Changxing Shipyard has also introduced a lot of Ukland shipbuilding experts and workers, and even not only Jiangnan Changxing, many of China's military enterprises have poached experts and skilled workers from Ukland, and it is with the addition of those Ukland experts and workers that China's military technology development has been accelerated a lot.
In the factory of Jiangnan Changxing Shipbuilding Group, you can also see many blonde and blue-eyed Uklanders.
Wang Dalu, Zhang Hong and others on the side also sympathized with the same disease, and they, the chief teachers, all went to Wukelan to pick up engines.
China's military industry has not only failed to solve the problem of heart disease in warships, but also military aircraft and tanks.
Although China's gas turbine started not too late, as early as the end of the fifties began to pre-research, but the technical level and industrial base at that time were too weak, so in the end it was decided to introduce it first, and then develop it itself.
At that time, China was able to introduce Lao Maozi's gas turbine, at that time Lao Maozi had a marine gas turbine M-1, although it was a phased product, and the refurbishment life was only 100 hours, but this also became the starting point of China's gas turbine.
In the end, this kind of gas turbine was successfully trial-produced, which allowed the design and manufacturing units to gain a certain amount of technical accumulation and experience.
Later, the design unit designed the first domestic marine gas turbine, although it was only 6,000 horsepower, although there was no object for loading ships because of the serious backwardness of the development progress, but it also created the history of self-developed marine gas turbine, which is of great significance.
Later, China started the development of a shipboard gas turbine using a turbojet eight engine, and finally this shipboard gas turbine was completed the durability test and was ready to be transferred to equipment production, but something happened again.
Originally, this power was intended to be used on the domestic 055 large missile destroyer, but due to the failure of the diesel engine of this large drive at the same time, the 8,000-ton destroyer project was finally stranded.
And the development and production of this gas turbine was stopped again because it lost its installed object.
However, although this gas turbine is ready to enter the production stage, there are still some problems, and if it is really equipped with an 8,000-ton destroyer, there are still many problems to be solved.
The first problem is the lack of power.
The actual power of the gas turbine for the eight refrigerated ships is only 16,000 kilowatts, and in order for an 8,000-ton destroyer to reach a speed of more than 30 knots, a single gas turbine is required to have a power of 23,500 kilowatts, which can only be achieved by two gas turbines and a diesel engine.
And if, like the "Spruance" class in the United States, four marine gas turbines are used, the power is still insufficient.
You should know that the total power of the four ML2500 gas turbines is more than 80,000 kilowatts.
But the four turbojets and eight changes are only more than 60,000 kilowatts.
A more serious problem is the longevity of the service.
The service life of the gas turbine for the turbojet eighth modification ship is only 200 hours, while the average destroyer needs at least 500 hours for a mission, so this cannot meet the installation requirements, and it is impossible for a destroyer to run out of power after only ten days of sailing, right?
You must know that on a warship, it is impossible to complete the overhaul of the power plant, and this is the most fatal problem.
Although in 95 years, the Kunlun turbojet engine was successfully developed, and the work of developing a gas turbine on this aero engine was also launched, but the power still could not meet the needs of the destroyer, and it could be used for power generation.
In Shen Huan's memory, these histories are very clear, and later after the 703 Institute introduced the DA80 gas turbine from Wuklan, it carried out imitation work.
It's just that it seems to be several years before mass production is completed.
Despite their heavy weight and high fuel consumption, there is no choice but to do so.
For this situation, although Shen Huan is a reborn, he is powerless to change it, because he is not engaged in gas turbines, and he has not thought of what role he can play during this visit to Wukelan!
Several old experts were silent, and Shen Huan saw that the time was not early, so he stood up and said, "Director Zhao, there are still a few experts, I believe that our heart disease problem will be solved sooner or later."
But before we can solve this problem, you have to take care of your health, so let's go back to our room early and rest, and we have to fly tomorrow for a day!

” Several experts nodded in unison, a long-distance flight is indeed very tiring.
Shen Huan and the experts also returned to their rooms, but Shen Huan was lying on the bed, unable to sleep for a long time, he thought a lot.
