FT8 gas turbine, according to the technical data given by Pratt & Whitney during development, the power of up to 78MW has far exceeded the 22MW of the LM2500 gas turbine, what kind of monster is such a thing used on a warship?

You can take a look at what level of gas turbines used by the world's navies, even the MT30 gas turbine used by the new generation of Queen Elizabeth-class aircraft carriers in Great Britain and Anti is only 36MW, and the big guys used in aircraft carriers have this level, and the current FT8 gas turbine has soared directly to 78MW, what is this going to do?

In other words, what kind of ambition does Pratt & Whitney have the courage to take out this kind of thing and cooperate with the Republic, after all, Pratt & Whitney's gas turbine is on the road of aviation to refueling, and this thing is in the same vein as the aero engine.

There are two kinds of gas turbine roads, one is the traditional industrial gas turbine road taken by Siemens, Alstom and Sanleng, which is huge in size and super powerful, one is nearly 100MW, or more than 100MW level, which is called industrial machine by the industry. The size of this gas turbine is even more than two stories high, which naturally brings the super power of a single gas turbine, and this gas turbine has little to do with the aero engine of the aviation port.

In the Republic, it is mainly the Dongfang Steam Turbine Factory, the Bingcheng Steam Turbine Factory, the Jinling Steam Turbine Plant and other units that are doing this kind of thing, and it seems that they have never heard of when these units got involved in the aero engine business, but the gap between them is too great.

The other way is the solution explored by aero-engine giants such as Rolls-Royce, GE and Pratt & Whitney: using aero-engines as the technical basis to derive light gas turbines. This gas turbine has the ability to be lightweight. The advantages of compactness and small size. However, because it is a solution based on aero engines, it also leads to a high frequency of maintenance. The power is also small, and it is called an aeroflight modification aircraft by the industry.

The industrial machine is huge in size, super power, and can only function as an onshore power plant, while the aircraft is different, although the power of the aircraft is small, usually a few MW or dozens of MW, and the top of the sky is 60MW. This is still something that the last face Puhui did not come up with until 2015.

Now that the 420 plant is cooperating with Pratt & Whitney, how can he have a maximum power of 78MW? Either way, it's not normal.

What is the truth? As a gas turbine for aviation refueling, how did the power of FT8 reach such an unnatural level, could it be that after the cooperation between Pratt & Whitney and the 420 factory, it was also infected with an exaggerated wind?

In fact, the 78MW data is not wrong, what is wrong is that the FT8 gas turbine is in the form of a unit, which means that the FT8 gas turbine can only reach this level by working together by several gas turbines.

This kind of use of units to increase the overall power is too common in the conversion of gas turbines, such as the Republic of China's 052 destroyer is used in the mode of two Lm2500 engine units and two diesel engine units.

The Spruance-class destroyers of the US imperialists, the Ticonderoga-class cruisers, the Arleigh destroyers, the Spruance-class destroyers, the Arleigh-class destroyers, the Spruance-class destroyers, the Ticonderoga-class cruisers, the Spruance Burke-class destroyers. All of them use the power system of four LM2500 gas turbine units, and the Soviet Kakhin class uses eight gas turbine super units.

These units are connected in parallel to achieve a uniform and distributed power output through a special drive system, and the final total power can still reach 100MW. So as to promote the operation of warships of different tonnages. The advantages of the small size of the gas turbine of this kind of aerodrometic reform have a very big temptation for warships. Charm, plus the advantages of smooth operation, low noise and fast start-up. It gradually became the standard configuration of the main ships of the Navy.

To talk about a thousand or ten thousand, it is still necessary to talk about the power of this single FT-8 gas turbine. The power of this single FT-8 gas turbine is not much, and the power in the design is only 24MW. Compared to the LM-2500 engine in the late eighties, this power is actually not too far behind.

In the 80s, the LM-2500 gas turbine power was in the position of 22.5MW, and it was not until the new century that the Yankees increased the power of the LM-2500 gas turbine to 34MW again according to specific needs, and the entire LM-2500 gas turbine sequence covered the entire range of 18-34MW, so as to squeeze all the potential of the LM-2500.

That's right, the single power in the design of the FT-8 gas turbine turbine reaches 24MW, and the thermal efficiency is 37%, which is even a little better than the LM-2500 gas turbine in the same period, that is to say, this FT-8 gas turbine is at the same level as LM-2500 in the power surface of the single unit, LM-2500 can meet the needs of 052, and FT-8 can also do this, which is after Southwest Science and Industry took over the 420 factory, The fundamental reason for continuing to do the FT-8 gas turbine project.

With Chief Wu sitting in charge of the gas turbine business of the 420 plant, the 420 factory can learn more things in the design of this gas turbine, so that the 420 factory can make the most adequate preparations for the future whether it is a completely localized FT-8 gas turbine or a new gas turbine.

However, now Yang Hui doesn't have time to go to the 420 factory to pay attention to what FT-8 gas turbine project, what will this thing develop into in the end Yang Hui doesn't care too much, even if this gas turbine can't continue in the end, Yang Hui can still have a variety of ways to come up with an engine of the same level as the LM-2500 gas turbine.

When he came to the 624 Institute again, Chief Engineer Liu seemed to have gotten the news a long time ago, and he had a chance encounter with Yang Hui at the gate of the Institute, which made everyone have to sigh with emotion.

"Chief Engineer Liu, didn't you say that there was no project in your hand last time, I brought you a project, a civil large bypass ratio turbofan engine core engine that can cover 3-5.5 tons of thrust, this is our Southwest Science and Industry next in the aero engine business of the biggest action, I don't know if 624 is willing to take over this project?"

I got the news from the Science and Technology Commission early in the morning, and now I heard that I was going to cooperate with the 624 Institute to develop a new small-thrust turbofan engine core engine, Chief Engineer Liu nodded and said that there was no problem, and motioned Yang Hui to go to the office with him to sit down and discuss the specific situation.

After sitting down, I saw that there was already a document on the desk, and after taking a look at this thing, Yang Hui's eyes gradually lit up, isn't this the core machine design data that is needed now, it seems that the pre-research of the 624 Institute has been aiming at the current needs early on, and the vision is quite vicious.

After putting the things away, Chief Engineer Liu turned around and saw Yang Hui's movements: "Yo, you have already seen it, how about it, how do you feel about the technical architecture of the core engine of the small thrust turbofan engine, our 624 Institute has carried out specific engineering design for this core machine, and there will be no problem in completing this project by using the mature technology we have developed before the core machine of the pusher." ”

Mr. Liu worked as the director of the 624 Institute, and the current situation of the aero engine of the Republic is also quite clear, when Yang Hui left the funds to ask the 624 Institute to conduct pre-research on the core engine of the small thrust turbofan engine, Chief Engineer Liu has guessed what level of core machine the demand of Southwest Science and Industry is, after all, the vacancy of Southwest Science and Industry in the aero engine line is a professional can see clearly.

Yang Hui was also very happy after seeing this information, he didn't expect that the 624 Institute was so clever and had started the development of the core machine in advance, which means that the development of the engine can be accelerated for at least half a year, which is an inch of time and an inch of gold for a civil engine.

"Yes, very good, I think we can continue according to this design plan, and we can almost meet all the needs of our new small push this time, but I don't know how long it will take to complete the development, and time is very important to us." (To be continued.) )
