Chapter 1504

You should know that the total power of the high-pressure boiler steam turbine power combination of the US Navy's "Kitty Hawk" aircraft carrier is 205 MW, with a total output of 274000 horsepower.

It promotes the owner of a behemoth with a standard displacement of 61000 tons and a full load displacement of 82000 tons. At the same time, it can provide up to 82 shipborne aircraft and a continuous maritime combat capability of more than 3000 people.

From this point of view, it seems that Zhuang Jianye proposed that the combination of four d-71m and four d-65f-plus full gas turbine integrated electric propulsion system is not enough to bear the power assembly of domestic 80000 ton large surface ships.

More precisely, its total power of 200 MW is a little less than the 205 MW on the Kitty Hawk.

However, the deputy head of the Navy did not have any objection, but nodded his approval very seriously.

The reason for this is very simple. The "Kitty Hawk" class is an old guy built and commissioned in the 1960s. It can be said that it can be a grandfather to today's Post-Zero. Many ship body designs still retain the experience of World War II. Compared with the fluid dynamics analysis model that has been developed to rapid explosion, it is unknown how many generations behind.

The domestic 80000 ton large surface ship is a proper product of the 21st century. Whether it is a ship body structure or a ship type structure, or its drag reduction ability, I don't know how much better it is than the "Kitty Hawk" of my grandfather's generation.

Because of this, in the 1960s, we needed super power to promote 80000 tons of big guys to gallop freely with great efforts. Now, through the wide application of advanced industrial design and fluid mechanics, combined with advanced manufacturing technology, we can make up for part of the power output.

So the total power of 200 MW and the total output of more than 268000 HP are not too little, but really just good.

what is it?

Good late development advantage!

The executive deputy group leader was very satisfied with this. He thought that when he went back in the evening, he would call his old chief and report today's affairs. I believe that after the Navy learned the news, it will transfer the focus of high-power marine gas turbine from da-80t of Aviation Development Corporation to d-71m of China Tengfei Aviation Power Co., Ltd.

No way, as long as you don't have a funny head, you should know that a marine gas turbine that can be used on amphibious attack ships and aircraft carriers is the real baby. The goods that have just passed 20 MW and are still faulty can only be used when you don't have to choose. Who else uses those with poor quality.

It's like paying public food every day and suddenly surging passion. Of course, the latter makes people's blood gush and can't extricate themselves!

Therefore, the executive deputy group leader nodded with satisfaction and talked to Zhuang Jianye about the details of the d-71m gas turbine, so that he could be more detailed when reporting to the old head of the navy in the evening, but before he could speak, a staff member hurried over.

The disturbed Deputy group leader could not help frowning and asked with some impatience: "what's the matter?"

"Er... Leader, it's been an hour!" the staff reminded carefully.

"An hour?" the Deputy group leader was stunned. He quickly raised his wrist and looked at the table below. He couldn't help laughing at himself: "I didn't expect that time passed so quickly. An hour passed so quickly!"

The face of the executive deputy team leader changed quickly, because the staff in front of him was also routine. The data of gas operation in the first hour was very important. Basically, the level of gas operation in the future could be seen in the first hour. Therefore, the operation data in the first hour must be reported in time.

So the Deputy group leader paused and continued to ask, "how's the data? Does it meet the requirements?"

"Others are roughly consistent with the requirements of the project team, that is, fuel consumption and thermal efficiency..." the staff said, and some became hesitant.

Seeing this, the executive deputy group leader waved his hand and gave some heroic instructions: "the large gas turbine of 30 MW level has filled the gap in China. We should be proud and proud of this alone. Some defects are not a concern. After all, it is a new product, so we should always leave some room for improvement..."

The executive deputy group leader in a good mood didn't deliberately pressure his volume, so he said it naturally in front of everyone. During the period, he didn't forget to look at Zhuang Jianye meaningfully. It was obvious that I like your d-71m very much. The problems of fuel consumption and thermal efficiency are not a matter, just a little fuel money, Whether the energy sector or the Navy or consumer can afford it.

Therefore, you, Mr. Zhuang, put your heart in your stomach. With me, it's no problem to let your d-71m gas turbine win all the shares, one third of it.

With this mentality, the executive deputy group leader almost inspired all the speech talents accumulated in the army and local offices. He didn't say anything in the whole process. He also quoted scriptures and witty words everywhere. However, in a word, the d-71m gas turbine is very good and powerful. I'm not only pink, but also very strong!

Looking at the attitude of the leader of his own family, other staff members could only nod and agree. Only the staff member in charge of reporting wanted to interrupt several times, but he couldn't because of the witty words of the executive deputy group leader. He was so anxious that he was sweating. Finally, the Executive Deputy group leader noticed that he was tired. Of course, he took a break first, so he took the thermos cup from the assistant's hand, Looking at the staff in front of him, he drank while holding a water cup and asked, "what else?"

"It's such a leader..." the staff who finally caught the opportunity no longer hesitated this time and said quickly: "The problem of fuel consumption and thermal efficiency is not too bad, but too good. According to our test results, the average fuel consumption of d-71m gas turbine in the first hour is 207 g · kW / h, and the maximum peak value is only 212 g · kW / h. It is concentrated in the power raising stage when starting up, and the remaining time is basically maintained at 207 g · kW / h. on the whole, it is very stable ！

There is also thermal efficiency, with an average of 40%, a peak of 42% and a minimum of 38%, which is also concentrated in the power improvement stage when starting up... "

With that, the staff looked up in disbelief and looked at the Deputy Group Leader: "At the beginning, we didn't believe this test result. The fuel economy of gas turbine is even lower than that of high-power diesel engine, and the thermal efficiency can reach 40%. We always think it shouldn't be our own product, but we used several sets of test equipment, and the results are the same. We are surprised that we have built a real world-class gas turbine ourselves With... "

"So, that's your expression? It's 207 g · kW / h fuel consumption, 40% thermal efficiency... What can it be... En? No, what did you just say? What's the fuel consumption of d-71m gas turbine? 207 g · kW / h?"

At first, the executive deputy group leader didn't feel much. He still drank water with the thermos. He suddenly felt something wrong. The next moment, the thermos in his hand fell directly from his hand to the ground, and the warm water in it immediately wet his feet.

But the executive deputy group leader didn't notice it at all. He took the monitoring report from the staff, and his tone was distorted: "darling, I'll make a big bang ~ ~ ~ what monster is this made by China take-off..."
