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

Not to mention the fact that it also gives quite detailed and exaggerated performance figures.

And the dazzling performance of the J-8C in the air show can also prove from the side that the figures on the display board are at least not completely fabricated out of thin air.

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 the audience, so there is no strict restriction on the specific business of exhibitors.

In short, there are many units that are completely unrelated to aerospace and have also sent people to help the field, and they all bear the name of aviation technology group.

This has created a strange scene in which the aviation technology group not only sells aircraft, but also sells guns, guns and tanks.

Of course, as the scale of the Xiangzhou Air Show became bigger and bigger, this situation became less and less, and everyone put on their real vests to come out for activities.

And Lin Qing's 701 Research Institute of Shipbuilding Industry is one of the brother units that came to help the field.

Naval vessels, even the smallest speedboats, are unlikely to be transported to the convention center.

In addition, they themselves knew that they were supporting actors, so they just brought a batch of models with rather rough workmanship and set up a few indoor booths, and they didn't think about what kind of business they could really do here.

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

Therefore, Lin Qing himself watched the flight show of the J-8C throughout the whole process, and witnessed the moment when the true face of the turbojet 14 was revealed from under the rainproof cloth.

But it's different from other onlookers who just watch the excitement.

At that moment, he felt that he had come to a good place.

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

After entering the 90s, with the development of the national economy, military spending has gradually become more abundant, and the procurement funds for naval equipment are no longer like in the past, when they could not buy a frigate a year, so they naturally have some pursuit of new equipment.

At that time, the latest frigate of the Navy was the 053H2G called the Jiangwei class by NATO, although it was equipped with anti-ship and anti-aircraft missiles at the same time, but the configuration of 6 YJ-8A and 6 Hongqi 61 can only be said to solve the problem, especially the performance of the latter is intolerable.

As for anti-submarine ......

Excuse me, but what is anti-submarine?

And the foundation of this model is still 053H2 designed in the early 80s, the potential for further development is already very small, two years ago 701 designed an export frigate for the **** Navy, verifying that the limit of this hull is basically about 2400 tons, it is impossible to meet the future needs of the Navy.

A completely new design of the corvette was imperative.

And from the very beginning, the technical scheme on the new corvette was divided into two lines.

The difference is mainly in the dynamics, but also in the choice of anti-aircraft weapons.

One is to further enlarge the hull on the basis of 053H2G, continue to use the Piertic 16PA6V series diesel engine as power, and 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, referring to the design scheme provided by Russia to our country in the early 90s, using gas turbines as power, and 4 groups of "long glove" short-range anti-aircraft missiles (in fact, Haijidoel) for point air defense, with a full load displacement of about 4200-4500 tons.

It is already almost in the same class as the Type 052 destroyer.

Both designs have their own advantages and disadvantages.

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

In particular, the French side refused to transfer the technical data of the STC system of the Piertic diesel engine, resulting in the low power of the domestic 16PA6V-280-STC diesel engine, which is only equivalent to the 12PA6V-280-STC of French origin, and requires 4 units to provide sufficient power.

The second option undoubtedly has better performance and greater potential, and the full-fuel power can bring congenitally lower noise and faster speed, and has an inherent advantage in anti-submarine warfare, and the air defense system with 4 groups of 8 vertical hair is also much more reliable than 1 8-unit Haihongqi 7.

However, as a price, the all-fuel power must not be as good as the diesel engine with lower idle fuel consumption in terms of extreme range, and the 30 sets of land-based Dowl M1 air defense missiles introduced by Huaxia last year have just begun to be delivered, and it will take at least a few years to digest and absorb relevant technologies and then develop the corresponding sea-based version, and it is likely that foreign weapons systems will need to be purchased in between.

In general, Lin Qing, as the designer of Party B, still prefers the second option.

Engineers, naturally, want to be able to get out of their hands perfectly.

However, the good times did not last long, not long after these two designs were proposed, General Electric cut off the supply of LM2500 gas turbines, and even the original 113 ships were almost not built, let alone enough to be used on frigates.

Almost at the same time, the Spey turbofan-based aero-fuel conversion project also came to an end.

I was going to walk on two legs, but now both legs are broken.

The power of the gas turbine scheme is simply gone.

Just before this trip to the Zhuhai Air Show, Lin Qing almost gave up his original idea, was ready to choose the diesel power scheme, and led his subordinates into the overall design stage.

However, the Turbojet 14 at the air show gave him renewed hope.

During the day, Lin Qing had already asked sideways, the leader from Sheng Jing's side was the youngest gay man, named Chang Haonan.

So after the dinner began, he came directly with a strong sense of purpose.

"Comrade Chang Haonan?"

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

After all, he is asking for help, although the person in front of him seems to be 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 and Research Institute of Shipbuilding Industry Co., Ltd., and this is my ID and work card."

"Uh...... Hello, Comrade Lin Qing. ”

An overly formal speech made Chang Haonan a little unresponsive, and he didn't expect to meet people from the shipbuilding industry system here:

"I didn't know you came to me ......"

"Oh, yes, I saw that turbojet 14 engine you brought over during the day today, so...... There are a few questions that I don't know and it's inconvenient to consult. ”

It's not that Lin Qing wanted to hold the shelf just now, it's just that the question he wants to ask is indeed a little sensitive, and if he doesn't identify himself at the beginning, it will be difficult to continue the topic.

Chang Haonan looked at the documents in front of him and verified the identity of the other party.

It's really a big guy.

"It's okay, excuse me, and besides, just call me Xiaochang."
