Chapter 142 New Frigate (Part 1)

The appearance of Turbojet 14 as a separate exhibit during the air show was quite unexpected.

Not to mention that it also provides quite detailed and exaggerated performance data.

And the J-8C's dazzling performance in the flight show can also prove from the side that the numbers on the display board are at least not completely fabricated.

Therefore, in addition to aviation industry insiders like Lu Yuying, it has also attracted the attention of many comrades in other systems.

Although the Xiangzhou Air Show has "Aerospace Expo" in its name, it may be to expand its audience, so there are no strict restrictions on the specific business of exhibitors.

In short, many units that have nothing to do with aerospace have also sent people to help, and they all bear the name of aerospace technology group.

This has created the spectacle of the Aviation Technology Group not only selling aircraft, but also guns, artillery and tanks.

Of course, as the Xiangzhou Airshow grew in size, this situation became less and less common, and everyone put on their real vests and went out to do activities.

The 701 Research Institute of Shipbuilding Industry where Lin Qing worked was one of the brother units that came to help.

It is impossible for something like a naval ship, even the smallest speedboat, to be transported to the convention and exhibition center.

In addition, they also knew that they were supporting roles, so they just brought a batch of models with rough workmanship and set up a few indoor booths without thinking about what business they could really do here.

As for the staff who came with them, except for taking turns leaving two people to watch the booth to prevent things from being stolen, they basically did whatever they wanted.

Therefore, Lin Qing himself watched the entire flight performance of the J-8C and witnessed the moment when the true appearance of the Turbojet 14 was revealed from under the rainproof cloth.

But it was different from the other onlookers who were just watching the fun.

At that moment, he felt that his trip was well worth it.

Because in the past year or two, Lin Qing has been responsible for planning the technical route for the new generation of guided missile frigates——

After entering the 1990s, with the development of the national economy, military expenditures gradually became more abundant, and naval equipment procurement funds were no longer unable to buy a frigate a year as in the past. Naturally, there was some pursuit of new equipment.

At that time, the Navy's latest frigate was the 053H2G called Jiangwei class by NATO. Although it was equipped with both anti-ship and anti-aircraft missiles, the configuration of 6 Eagle 8A and 6 Hongqi 61 can only be said to solve some problems, especially in the rear. Its performance is unparalleled.

As for anti-submarine...

Sorry, what is anti-submarine?

Moreover, this model is based on the 053H2 designed in the early 1980s, and the potential for further development is already very small. In the past two years, 701 Institute designed an export-type frigate for the Chinese Navy, which verified that the limit of this hull is basically 2400 tons, it is no longer possible to meet the future needs of the Navy.

A completely new frigate design was necessary.

From the beginning, the technical solutions for the new frigate were divided into two routes.

The difference mainly lies in power and the choice of anti-aircraft weapons.

One is to further enlarge the hull based on the 053H2G and continue to use the Pierstik 16PA6V series diesel engine as power. The weapon system is directly copied from the Type 052 destroyer, with a full load displacement of about 3800-4000 tons.

The other is more thorough. It refers to the design plan provided by Russia to our country in the early 1990s. It uses gas turbines as power and 4 sets of "Long Glove" short-range air defense missiles (actually Sea-based Doyle) for point air defense, with a full load displacement. About 4200-4500 tons.

It is almost at the same level as the Type 052 destroyer.

Both designs have their pros and cons.

The technical risk of the first option is relatively low. Most of the systems on the ship are mature technologies that our country has mastered, but its combat effectiveness and development potential are relatively low.

In particular, France refused to transfer the technical data of the Pierstik diesel engine STC system, resulting in the low power of the domestic 16PA6V-280-STC diesel engine, which is only equivalent to the 12PA6V-280-STC originally produced in France. Four units are needed to provide sufficient power. motivation.

The second option is undoubtedly better in performance and has greater potential. Full combustion power can bring inherently lower noise and faster speed. It has inherent advantages in anti-submarine warfare. 4 groups of 8 vertical launchers The air defense system is also much more reliable than an 8-unit Haihongqi 7.

However, as a price, full-combustion power is bound to be inferior to diesel engines with lower idle fuel consumption in terms of extreme range. Moreover, the 30 sets of land-based Tor M1 anti-aircraft missiles introduced by China last year have just begun to be delivered. In order to digest and absorb relevant technologies and then develop corresponding The sea-based version will take at least a few years, during which time it is likely that external procurement of weapon systems will be required.

Generally speaking, Lin Qing, as a designer of Party B, still prefers the second option.

Engineers naturally hope that the plans coming out of their hands will be perfect.

However, the good times did not last long. Not long after these two design plans were proposed, General Electric cut off the supply of LM2500 gas turbines. Even the original 113 ships were almost not built, and it was even less likely to come up with sufficient quantities for use. On the frigate.

Almost at the same time, the aeroderivative fuel project based on the Spey turbofan engine also came to an end.

The original plan was to walk on two legs, but now both legs are broken.

The power of the gas turbine project was completely lost.

Just before the Zhuhai Air Show, Lin Qing had almost given up on his original idea, prepared to choose a diesel power solution, and led his men into the overall design stage.

However, the turbojet 14 at the air show gave him hope again.

During the day, Lin Qing had already asked insinuatingly that the team leader from Shengjing was the youngest-looking gay man named Chang Haonan.

So after the dinner started, he came directly with a strong purpose.

"Comrade Chang Haonan?"

Seeing Chang Haonan ending the conversation with Lu Yuying, Lin Qing hurriedly came to the former's side.

After all, he was asking for help. Although the man in front of him looked about the same age as his son, he still introduced himself in a very polite tone:

"Hello, I am Lin Qing, deputy chief engineer of the 701 Design Institute of Shipbuilding Industry. This is my ID and work badge."

"Uh... hello, Comrade Lin Qing."

Chang Haonan was a bit unresponsive to the overly formal speech, and he never expected to meet someone from the shipbuilding industry system here:

"I don't know why you came to me..."

"Oh, that's right. I saw the turbojet 14 engine you brought here during the day, so... I have a few questions that I don't know how to consult."

It's not that Lin Qing just wanted to put on airs. The question he wanted to ask was indeed a bit sensitive. If he didn't reveal his identity at the beginning, it would be difficult to continue the topic.

Chang Haonan looked at the ID in front of him and verified the other party's identity.

A big shot indeed.

"It's okay, please. Also, just call me Xiao Chang."
