Since the army is still pursuing the alternation of firewood and fuel as always, Wang Zhengguo can give a more compact intercooler system, which is a more cutting corners intercooler system.

"Diesel fueling power, means that warships use diesel engines to do 15 knots of economic navigation most of the time when a voyage, only when the emergency is required to use gas turbines, in fact, at this time the power of a single engine of 17 megawatts is not low, two Minjiang 170 gas turbines at the same time, enough to increase the speed of the warship to 27 knots. ”

Does what Wang Zhengguo said make sense?

Of course, it makes sense that the warships of the diesel-fuel joint use gas turbines are really not much time, which is the conclusion reached by the Navy of the Republic after a long period of research, and strongly supports the continued use of the No. 2 ship of the 052-class destroyer, and there are only two LM-2500 ships left in the country at that time.

You must know that after 89 years, the Republic arrived four LM-2500s, and the construction of the first ship of 052 had already started, but the United States imposed sanctions on China, so the military plan was to stop the manufacture of the No. 2 ship of the 052 class, and the other two LM-2500 gas turbines were used as backup for the No. 1 ship.

Later, it was demonstrated that because the diesel-fuel joint scheme uses diesel engines as the power most of the time, and gas turbines are rarely used, the loss of LM-2500 will not be too large, and the backup engine scheme is not necessary.

As a result, the construction of the No. 2 ship of the 052 class was continued, and the facts also show that the power system of these two warships does rarely use gas turbines.

Now that the navy has understood the law of alternating the use of firewood and fire, and knows that the number of hours of using gas turbines on a voyage will not be too many, Wang Zhengguo does not mind helping them add another fire.

"In a voyage, the gas turbine is not used for a long time, and even if the gas turbine is used, most of the time there is no need for intercooler intervention, just 27 knots of speed is enough, really to full power output, I am afraid it is even rarer, a voyage can have 20 hours to the sky in this situation. ”

The big guy was born in the navy, and he quite agrees with Wang Zhengguo's statement.

"It makes sense, there are only a handful of times when a warship fights at full power after it sets sail, but the margin of twenty hours is not enough, you double it for me, 48 hours, so that my heart can be stabilized. ”

It doesn't matter if it's 20 hours or 48 hours, it doesn't really make a big difference, continued.

"That's okay, anyway, most of the time warships use diesel engines for economic speed, then our gas turbine intercooling technology does not have to use a cumbersome water cooling system, directly use liquid nitrogen intercooling technology, after a small amount of liquid nitrogen is introduced to the heat exchange tube, you can achieve the air cooling needs, such a set of devices, the intercooling system can be very small, and go to sea for training, the liquid nitrogen required will not exceed 1 ton at most. ”

The use of liquid nitrogen as an intercooling system can meet the characteristics of the gas turbine that does not have much service time in a single voyage, such as the alternation of diesel fuel and fuel, and realizes the need to arrange the engine in a small power compartment.

Liquid nitrogen intercooling, this is a more interesting plan, the big guy has some understanding of military equipment, and after a little thought, he knows that this technical route has a certain feasibility.

"Listen to what you say, it should be similar to the water spraying of aero engines to increase thrust in the United States and the Soviet Union, and I will let the Navy do research when I go back, and now you can tell me what data can be achieved by the power system you provide if this technology is adopted?"

After roughly approving the technical solution, since he asked about the specific data of the power system, this Wang Zhengguo did not have to worry, he could be said to be confident.

"The volume and weight should not add up to more than LM-2500, about 15% more, but its advantage is that after starting the intercooling system, the engine thermal efficiency can reach more than 37%, and when it reaches the international first-class level, the life of the unit can reach at least 20,000 hours. ”

Wang Zhengguo gave such data, is it very bad?

Of course not, in fact, the data he gave has been comparable to the LM-2500 gas turbine above the 052, especially in terms of thermal efficiency, the peak data is two percentage points higher, and this is the strength.

"The question of when the equipment will be delivered is critical, and it is related to the subsequent development node of the 052 series improved model, as well as the question of whether we want to introduce the Soviet AM-50 gas turbine. ”

When it comes to the question of time, Wang Zhengguo's proposal of this plan seems complicated, but the technical difficulty is not great, and the research and development time will not be long.

"At most three years, we can deliver in full state, now United Power Energy Group has a full set of system research and development experience, as long as the Navy is determined to do it, we will be able to get this power plant within three years, as for AM-50, it is better to introduce the Ukrainian Dawn side of the M-80 is more suitable, the future use of four engines as the power system, can start the 10,000-ton cruiser program, the Navy is engaged in the development of four-sided fixed phased array radar, Kaiyang Semiconductor also participates in the corresponding gallium arsenide T/ Isn't that what the R component was developed for?"

After hearing this, the big guy looked at Wang Zhengguo very meaningfully, but he smiled faintly, the 055 that was launched in the seventies was only 8,000 tons, and now Wang Zhengguo is shouting to engage in a 10,000-ton drive, and the young man is really thoughtful.

"Talk tighter, don't talk about the 10,000-ton drive, and now the army is trying to get the 052 series modification out as soon as possible. ”

Since it is a modification of the 052 series, then think about it, it should be a 052B destroyer, and this is not wrong.

With the Minjiang 170 gas turbine and intercooled system, it can indeed reach the 20 megawatt level, but the hull made in this way will not exceed 5,000 tons at most, so it depends on the choice of the navy, whether to cut off part of the air defense capability or cut the anti-ship capability, after all, the violent 16 anti-ship missiles on the upper plane 052B are really too scary.

Fortunately, the later 052C is no longer so evil, and the 8-round anti-ship missile scheme is the main option, which actually shows that if you have to choose between air defense and anti-ship, the navy will definitely choose air defense.

"If 052 is changed, I feel that the Shikili shipborne air defense system on the Maozi Modern class is good, and if it can be introduced back, it should be good for 052. ”

Hearing this, Wang Zhengguo did know a lot, and the big guy didn't have a good breath:

"A few days ago, the 819 incident broke out in the Soviet Union, including the introduction of the Su-27 production line, negotiations have been suspended, anyway, the situation over there is not clear, to introduce such a thing as a shipborne air defense system, it's hard to say!"

Although this is the case, what I really think in my heart is obviously another matter, the Soviet Union is willing to sell the Su-27, a long-range third-generation fighter that can threaten the territory of the Soviet Union itself, such as the ship-based air defense system, which obviously poses a greater threat to the United States and Japan's maritime powers, and there is no reason not to sell it.

Make up your mind, as long as the two sides start military cooperation negotiations again, this set of Shikili shipborne air defense system must be introduced into negotiations, which is the source of the 052 follow-up model to ensure regional air defense combat capability.
