Chapter 1503

As soon as this remark came out, the executive deputy group leader couldn't help patting his head: "Oh, those in the game, those in the game. Look at my head, how can I forget the d-65f gas turbine? This is the most stable gas turbine in the Navy at present. I went to the ship detachment to investigate when I was in the Navy. The front-line engine officer said more than once that the reliability of the d-65f gas turbine is better than the lm2500 made in the United States!"

The executive deputy group leader's remark is not a compliment to Zhuang Jianye. In fact, among the gas turbines equipped by the domestic Navy, d-65 series marine gas turbines are really the most reliable and stable.

Because of this, this gas turbine is widely used in 037 series submarine hunting missile boats, 081 series minesweepers, 918 series minelaying ships, 053h series frigates and some auxiliary ships such as ocean observation.

Among them, the 037 improved hunting submarine is equipped with two d-65b 6 MW small gas turbines with a total power of 12 MW and 16092 HP. Compared with the original 037 powertrain with less than 15000 HP, it is not only more compact, but also has greater power output. Therefore, since the late 1980s, the Navy has upgraded the powertrain of more than 30 037 hunting submarines and replaced them with d-65b small gas turbines Machine.

The 037 II missile boat equipped by the troops stationed on Hong Kong Island is equipped with d-65b-max marine gas turbine.

The maximum power is the same as that of d-65b, which is 6 MW. 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-max marine gas turbine uses the marine gas turbine digital control system developed by China Tengfei based on the digital full power control system used on the aeroengine System.

It makes the operation more convenient and flexible, especially in shallow water. Its mobility is no less than that of small motor boats. Therefore, it has been highly praised by both inside and outside the Navy as soon as it is loaded in a row.

In particular, the Marine Police Department of the Hong Kong Island police station, after visiting and experiencing the driving experience of the 037 II missile boat, resolutely eliminated British goods, signed a contract with domestic shipyards to install the sea patrol boat improved based on the 037 II missile boat, and named that China must install the d-65b-max marine gas turbine. This order alone allowed China to sell 12 d-65b-max marine gas turbines.

The total value exceeds HK $300 million.

The 081 Minesweeper uses a d-65c 8 MW marine gas turbine with a power output of more than 21000 horsepower, so that the 081 Minesweeper with a full load displacement of just over 1000 tons not only has strong mobility and acceleration, but also greatly improves its ocean combat capability.

Similarly, there are two improved 918 mine laying ships equipped with d-65e 10MW marine gas turbines. Due to different mission requirements, although the full load displacement of the improved 918 mine laying ship has reached 2300 tons, the requirements for speed are small. Therefore, the two 10MW gas turbines provide 26000 horsepower, and the speed of 28 knots is more than enough.

Compared with several other models, the d-65f marine gas turbine is the one that makes China take off the most, because it is equipped with 053h series missile frigates, the main naval frigates.

From 053h2g in the mid-1990s to 053h3 later, except that the early ships used four domestic high-power medium speed marine diesel engines, the remaining ship types all used two d-65f 12 MW marine gas turbines, providing a total power of 24 MW and a total output of 32000 horsepower.

It can push the frigate with a full displacement of 2500 tons to a high speed of 32 knots and a high endurance of 18 knots of 4500 nautical miles.

In addition, d-65f marine gas turbine inherits the excellent operability and reliability of d-65 series, which greatly improves the combat effectiveness of 053h series missile frigates.

Of course, it has also made a lot of money for China's take-off.

After all, as the main ship of the Navy, 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 marine gas turbine production plant of China Tengfei Aviation Power Co., Ltd. (Group) has not stopped since the late 1990s, and has maintained almost full load operation.

It was not until the launch of the domestic 4000 ton frigate in the past two years that the power performance of the d-65 series marine gas turbine really couldn't keep up, and the required 20 MW large marine gas turbine was delayed, which was once again occupied by the high-power marine diesel engine.

So as to end the brilliance of d-65 series for ten years.

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

In particular, the amazing iterative speed and technological upgrading of China's take-off are absolutely visible to the naked eye. From d-65b to d-65f, it is completely a step by step, and finally build a complete marine gas turbine product line of small and medium-sized surface ships from 500 tons to 2500 tons.

It's the same as the goddess's aunt towel with side leakage and night leakage prevention for the first time. Except for a very considerate word to describe it, there's really no other word to summarize.

The reason for this is very simple. Most of the parts of the d-65 series marine gas turbines of the whole series are common. Needless to say, the relevant production lines also come from one place, which is very friendly to the maintenance and repair of the whole series of products.

As for a naval exercise, the power system of the 053h3 missile frigate of a frigate detachment broke down suddenly, and it was obviously too late to rely on the port for maintenance. Therefore, the chief engineer had a whim and removed the accessories of the d-65e 10MW gas turbine on a 918 mine laying ship docked in the port ready to return to the factory for overhaul for temporary use.

As a result, it is really feasible.

Later in the exercise, the missile frigate completed various tasks excellently and was praised by the superior leader. The chief engineer who repaired the d-65f with d-65e accessories was awarded the second class merit for his excellent performance at this time.

There are many similar situations in the Navy, so that many old chief engineers of the navy are familiar with the d-65 series, just like the teacher Fu of the garage is familiar with the old Jiefang automobile. They don't have to look at any problems. They can know what's wrong by listening, smelling and touching.

However, because of this, when the Navy's 052 missile destroyer and the subsequent 052B series were in service, the transfer of the former chief engineer was very uncomfortable.

This is like the crazy output of the tacit understanding between the old warm man and his wife. Suddenly, he changed a proud young lady. Don't say a look. An action can't be obtained by the other party. Even if he is coaxed by sweet words, his warm and fiery performance, the other party is just like a blind man, all of them are invisible.

In such a situation, everyone will be particularly depressed.

Naturally, when you want to use China's take-off products, you can directly understand the tacit understanding of racing with one look. That's powerful. Straight men should go straight!

Because of this, China's soaring d-65 series is not generally good in the mouth of the Navy. It's just good enough to explode.

The executive deputy leader, a cadre of the Navy leadership profession, naturally knows better than anyone, but he is clear. Even if the d-65f has a power of 12 MW, it seems that it is still a little short of the heat for a large surface ship of 80000 tons.

As a result, before the executive deputy group leader asked questions, Zhuang Jianye added a meaningful sentence: "Well, at present, we have upgraded a d-65f-plus marine gas turbine on the basis of d-65f. The main improvement point is to increase the power from the current 12 MW to 15 MW. Four d-71m and four d-65f-plus can provide a total power of 200 MW and a total output of more than 268000 HP. This level has been compared with the" Kitty Hawk "of the US Navy ’The power assembly of class a aircraft carrier is roughly the same, which fully meets the power needs of large surface ships of 80000 tons! "
