Relying on this perseverance, Zhuang Jianye can be regarded as supporting the Karakoram Pass earthquake rescue operation.

Although it was expensive, it received a lot of praise, including from the Russians, with countries such as Pakistan and Iran showing great interest in the Z-12 and Z-15.

In addition, it is excluded that the expert group will come to China to conduct further performance tests on the Z-12 and Z-15, and Tengfei Group will of course do its best to entertain in order to ensure that the tests in several countries can be carried out in a smooth and orderly manner.

Some of them enter the pit, and some of them are unmoved.

After observing the "excellent" performance of the Z-12 and Z-15 in the plateau area, the Russian military observers at that time believed that China's helicopter technology level was no less than that of Russia, and in order to maintain Russia's helicopter industrial capacity, they proposed to China to carry out joint development and production of helicopters.

For this reason, the Russians specially dispatched a team of aviation experts headed by Djokovic to visit China, and after inspecting several major helicopter production plants in China, Djokovic quickly grasped the crux of the problem.

The performance indicators of Z-12 and Z-15 and other helicopter models are good, but most of them are not mature, especially Z-12 and Z-15, the failure rate of many subsystems is high, and maintenance is difficult, so Djokovic and others expect that these two models want to move towards real maturity, at least 5 years of running-in and improvement.

Because of this, Djokovic suggested to Russia that there is no need to rush to start helicopter production cooperation with China, and only need to appropriately reduce the unit price of the Mi-171 and Ka-27 helicopters, which can seriously hit China's domestic helicopter manufacturing industry.

Djokovic's advice was quickly adopted in Russia, and the Mi-171 and Ka-27 helicopters were further reduced to 25 percent below Russia's usual international offers.

This is not to mention, the two helicopters are equipped with a lot of advanced electronic equipment and weapon systems developed at the end of the Soviet Union, and they are bundled with the "Modern" class missile destroyer, the "Doyle" M1 short-range air defense missile, and the S-300 long-range air defense missile.

For example, the carrier-based helicopters of the "Modern" class missile destroyers can only use the Ka-27, and other helicopters can also be used, but there is no guarantee that they will be compatible with the "Modern" class missile destroyers.

Another example is that the covering force supporting the S-300 long-range anti-aircraft missile must use the Mi-171, otherwise...... Otherwise, the S-300 long-range anti-aircraft missile will not be sold, as for why, the combat manual of the Russian Air Defense Forces stipulates so, why do you say?

Relying on this routine, the Russians dumped a large number of Mi-171 and Ka-27 into the country.

Although the country's military spending has risen somewhat after a major event, because of the endurance period of the past 20 years, the troops have too many debts, and the increased military spending cannot make up for the arrears, so there is no immediate change at all.

Therefore, how big the army's plate was, it is still that big.

Because of this, the Mi-171 and Ka-27 poured into the troops, and the chances of other models were very slim, coupled with the competition for a large number of domestic models, the market share was further compressed, coupled with the defects of the Z-12 and Z-15 themselves, resulting in the number of two helicopter equipment of the Tengfei Group is not ideal.

It was only the Army Aviation Unit that symbolically purchased 4 Z-12 and 2 Z-15.

This is still based on the outstanding performance of Tengfei Group in the Karakoram Pass earthquake relief, and the headquarters does not say that it is really unwilling, so it is difficult to purchase a small batch, which is mainly used for emergency transportation in the plateau area.

Yes, it's not daily transportation, it's just emergency transportation, because there are S-70 helicopters for daily transportation, that is to say, with the current urine of Z-12 and Z-15, the army aviation does not dare to let it pick up the girder, and can only make an emergency equipment to fill the hole in an emergency.

This is true of both the army and the navy, and needless to say, the more picky air force and navy, except for the propaganda of the Z-12 and Z-15 in their respective organ publications, and after taking a bunch of muscular beautiful photos, there is no follow-up.

The most down-to-earth and reliable troops are like this, not to mention other departments, the domestic aviation industry is very lagging behind, and the domestic people even travel by plane is quite a luxury, not to mention the personalized aviation service of helicopters, which naturally has few applicants.

There is not even a basic market foundation, coupled with the shortcomings of the Z-12 and Z-15 themselves, the sales results of the two helicopters can only be described as dismal.

Helicopters are just like smartphones more than ten years later, it is a thing that relies on the experience of the market, and only in the market can the configuration of each system be improved step by step according to the actual use of users, and finally become a mature classic.

The same is true of the helicopter industry in the United States and the former Soviet Union.

In fact, Zhuang Jianye also wants to follow the old path of the United States and the Soviet Union, relying on the domestic experience of the Z-12 and Z-15 helicopters, just like the core masterpiece of the fixed-wing aircraft of Tengfei Group, the Y-15.

As a result, Zhuang Jianye's heart is good, but the domestic helicopter industry is not like transport fixed-wing aircraft, not to mention a hundred schools of thought, but also a forest of princes, coupled with European and American civil aircraft, Russian military aircraft poured in, encroaching on the mature market, making the situation of domestic helicopter manufacturers who pinch each other more difficult.

At that time, the Y-15 just filled the gap of high-performance light transport aircraft, coupled with the inflated prices of similar products in the world, and the products of domestic friends were not yet mature, resulting in the Y-15 becoming the only part of the scorpion baba, which gave the Tengfei Group the opportunity to brush up on experience.

On this basis, the models and engines were continuously improved, and finally derived a series of military transport aircraft and regional airliners such as Y-15plus, Y-15, Y-17, TRJ-500 and so on.

With such an obvious success story, why does the Tengfei Group, which is well versed in the way of brushing up experience, want to reproduce the glory of today's Y-15 on a helicopter, but the problem is that the situation in China is like this, what should we do?

So when Pakistan and Iran came to inspect the two helicopters, Tengfei Group was like a delicate little lady, doing everything possible around the steel pipe.

Take the Z-12 helicopter as an example, originally such a 4-ton helicopter could carry two light anti-submarine torpedoes, but in order to highlight the independent combat capability of the Z-12 at sea, the Tengfei Group simply increased the engine power, re-optimized the structure, and loaded the four torpedoes on the pylons, which flew in front of the Pakistani inspection team.

Seeing that the relevant Pakistani personnel were amazed, they kept asking Zhuang Jianye, who was personally accompanying him at the time, whether he really had the ability to do so.

How could Zhuang Jianye say that the Z-12 with four torpedoes is just like a fly, unless you dismantle the entire set of anti-submarine search equipment, it is almost the same, and he nodded shamelessly again and again: "Don't worry, don't talk about loading four torpedoes, even if you install six, you can still use it!"
