As soon as these words came out, the executive deputy team leader involuntarily patted his head: "Oh, the authorities are fans, the authorities are fans, look at my head, why have I forgotten the D-65F gas turbine? This is the navy's current performance. A stable gas turbine. When I was in the navy, I went to the naval detachment to inspect. The frontline turbine officer said more than once that the reliability of the D-65F gas turbine is better than that of the US-made LM2500!"

This is not a compliment to Zhuang Jianye by the executive deputy team leader. In fact, among the gas turbines currently equipped by the domestic navy, the D-65 series naval gas turbines have the highest reliability and the best stability.

Because of this, this gas turbine is widely used in the 037 series of submarine hunters\missile boats; the 081 series of minesweepers; the 918 series of minelayers; the 053H series of frigates and some auxiliary ships such as ocean observation.

Among them, the 037 improved submarine hunter is equipped with two D-65B 6 MW small gas turbines with a total power of 12 MW and 16092 horsepower. Compared with the original powertrain of the 037 which is less than 15000 horsepower, it is not only more compact, but also has a larger power output. Therefore, since the end of the 1980s, the Navy has upgraded the powertrains of more than 30 037 submarine hunters and replaced them with D-65B small gas turbines.

The Type 037Ⅱ guided missile boat equipped by the Hong Kong Island Forces is equipped with a D-65B-MAX type naval gas turbine.

The maximum power is the same as D-65B, both are 6 MW, and the key core components are not essentially different from D-65B. The only difference is that the D-65B control system uses the traditional mechanical hydraulic system, while the D-65B control system uses the traditional mechanical hydraulic system. The 65B-MAX marine gas turbine uses a marine gas turbine digital control system developed by China Ascendas based on the digital full control system used on aero engines.

It makes the control more convenient and flexible, especially in shallow waters, and its mobility is no less than that of a small motorboat. Therefore, it has won unanimous praise from both inside and outside the navy as soon as it was installed.

In particular, the Marine Police Department of the Hong Kong Island Police Department, after visiting and experiencing the driving experience of the Type 037Ⅱ guided missile boat, decisively eliminated the British cargo, and signed with the domestic shipyard a maritime patrol boat based on the improvement of the Type 037Ⅱ guided missile boat. It is necessary to install China Ascendas D-65B-MAX naval gas turbines. This order alone allowed China Ascendas to sell 12 D-65B-MAX naval gas turbines.

The total value is more than 300 million Hong Kong dollars.

The Type 081 minesweeper uses a D-65C 8 MW marine gas turbine with a power output of more than 21,000 horsepower. The 081 minesweeper, which has a full load displacement of just over 1,000 tons, not only has strong mobility and acceleration. , The ocean-going combat capability has also been greatly improved.

Similarly, there are two modified 918 mine-laying ships equipped with D-65E 10 MW naval gas turbines. Thanks to different mission requirements, although the improved 918 mine-laying ship has a full-load displacement of 2,300 tons, its speed is The requirements are not large, so two 10 MW gas turbines provide 26,000 horsepower, and a speed of 28 knots is more than enough.

Compared with several other models, the D-65F naval gas turbine is what makes China the most prosperous, because the ship type it is equipped with is not the next one. It is the 053H series guided missile frigate, the main force of the naval frigate.

From the 053H2G in the mid-1990s to the later 053H3, except for the first few ships that used four domestic high-power medium-speed marine diesel engines, the rest of the ships used two D-65F 12 MW. The marine gas turbine provides a total power of 24 megawatts and a total output of 32,000 horsepower.

It can propel a frigate with a full load of 2500 tons and a high speed of 32 knots and a high endurance of 4,500 nautical miles at 18 knots.

Coupled with the excellent operability and reliability of the D-65F marine gas turbine inherited from the D-65 series, the combat effectiveness of the 053H series of guided missile frigates has been greatly improved.

Of course, it also allowed China to take off and made a lot of money.

After all, as the navy’s main ship, the number of ships built is very large, and the gas turbines used are naturally not a small number. Because of this, the production line of the naval gas turbine production plant of China Ascendas Aviation Power Co., Ltd. (Group) It hasn't stopped, and it has been operating at almost full capacity.

Until the past two years, the domestically produced 4,000-ton large frigate was launched. The power meter of the D-65 series naval gas turbines could not keep up. The required 20 MW large naval gas turbines could not be available for a long time. The market was regained by high-power marine diesel engines.

Thus ending the ten-year brilliance of the D-65 series.

Although somewhat regrettable, it is undeniable that the experience of using the D-65 series for more than ten years has left a deep impression on the Navy.

Especially the astonishing speed of iteration and technological upgrades of China Ascendas is absolutely visible to the naked eye. From D-65B to D-65F, it is completely step by step, and finally a set of the whole series from 500 tons to 2500 tons. A complete marine gas turbine product line for small surface ships.

It is the same as the first time the goddess used the aunt's towel with side leakage and night leakage. Apart from using a very intimate description, there is really no other word to generalize.

The reason for this is very simple. Not to mention that most of the parts of the D-65 series of marine gas turbines are common, the related production line is also from one place, which is very friendly to the maintenance and maintenance of the entire series of products.

For that particular naval exercise, the power system of the 053H3 guided-missile frigate of a certain frigate detachment had a sudden failure, and it was obviously too late for port maintenance. So the chief engineer had a whim and sent a 918 docked in the port to be returned to the factory for overhaul. The parts of the D-65E 10 MW gas turbine on the minecraft were removed and used temporarily.

It turned out to be really feasible after a try.

In the exercises that followed, the guided missile frigate successfully completed various tasks and was commended by the superior. The chief engineer who repaired the D-65F with D-65E accessories was awarded second-class merit because of his outstanding performance at this time.

There are many similar situations in the navy, so that many old chief engineers of the navy treat the D-65 series just like the masters of the auto repair shop treat the old Jiefang Automobile, and those who are familiar with them are just like their own wives. You don't need to punch your eyes to see if you have any problems, you will know what went wrong by listening, smelling, and touching.

But because of this, when the Navy's 052 guided missile destroyer and the subsequent 052B series were put into service, the chief engineer who was transferred from the past was very uncomfortable.

This is accustomed to the crazy output of the old warm man and his wife, and suddenly changed to a arrogant eldest lady, not to mention a look, an action can not be obtained by the other party, even if sweet talk, enthusiasm The performance of the other party is just like a blind man, all of whom are blind.

Anyone in this situation will be particularly depressed.

Naturally, thinking about when to use the products of China Ascendas, UU reads www.uukanshu.com with a tacit understanding of drag racing with one look. That's why it's so exciting. If you are a straight man, you should go straight!

Because of this, China's soaring D-65 series is not so good in the navy's mouth, it is so good that it explodes.

The executive deputy team leader, a professional naval leader, naturally knows better than anyone else, but clearly understands that even the D-65F has 12 megawatts of power, which seems to be not good for a large surface ship of 80,000 tons. It's getting hot.

As a result, before the executive deputy team leader could ask a question, Zhuang Jianye added meaningfully: "That's it. At present, we have upgraded a D-65F-plus marine gas turbine based on the D-65F. The main improvements are The point is to increase the power. From the current 12 MW to 15 MW, the four D-71M and the four D-65F-plus can provide a total power of 200 MW and a total output of more than 268,000 horsepower. This level is already roughly the same as the powertrain of the U.S. Navy’s Kitty Hawk-class aircraft carrier, and fully meets the power requirements of a large surface ship of this level of 80,000 tons!"
