This must be specially developed. For example, the turbofan-500 in the later Han Kingdom was a small turbofan engine with a thrust of 500 kg. This kind of engine is small in size and has a good fuel consumption rate. It can be used as a Cruise missiles, UAVs, and other aircraft are the main power sources. Now, this type of engine should be included in the domestic development plan.

After all, in the future, it will be the world of drones. UAVs do not need too high power, but they have high requirements for long range and so on. For example, large-scale drones such as Eagle Country’s Global Hawk. It's time for China to enter the state of research and development.

The development of unmanned aerial vehicles requires the support of electronic technology. In the era of electronic tubes, it was a idiot to engage in unmanned aerial vehicles. Now, with the rapid development of electronic technology, these have a technical foundation.

In addition to the engine, there is also a series of development of cruise missiles. The missiles in front of us are dedicated for special purposes. That's fine. However, to use this missile as a basis, a series of development is needed. Shipborne, air-launched Yes, land-based cruise missiles form a system. If the length is about 6 meters, the most suitable, the diameter is also best to be controlled at about 50 cm, and the range should reach more than 2,000 kilometers, deep into the inland of some countries. Strike the target, and at the same time search for the enemy from a long distance, so that you can avoid getting into danger.

As for the principle of low cost, of course, it must be implemented. After all, this thing is not a cannonball. If it is used like a cannonball, no richer country can afford it. It must be cheap to use it.

Qin Guan knew that these words were not of much use to the people present. He had to find experts from the Academy of Aerospace Engineering and the team that developed cruise missiles. Then, he would give them a few cruise missiles and let them Imitation, so as to achieve the best results.

Anyway, I am in the country, and I am in a state of idleness, so I will check it out another day.

As for now.

After Qin Guan visited the base, he went to the canteen of the base and had dinner with everyone. Captain Xu sat next to Qin Guan, eating and talking.

"Now, in our country, the construction plan for the last Class 091 submarine has been cancelled." When Captain Xu said this, the muscles on Qin Guan's face moved.

Class 091 is the first-generation missile nuclear submarine in China. The most important role at that time was to solve the problem of nuclear submarines. It was very noisy and its technology was backward. However, it achieved a zero breakthrough. Since then, the Navy has nuclear submarines!

Now, technology is developing rapidly, and the technology of the 091 nuclear submarine has long been behind. Although many data may not be true, there is no doubt that the performance of the nuclear submarines of Xiong and Ying are advanced.

At this time, the subsequent construction of the 091 nuclear submarine was stopped. The construction of nuclear submarines cost a lot of money. Now, the performance is still so backward, the Navy really does not have this confidence.

"Yes, our navy is looking forward to a new generation of nuclear submarines. Now, our submarine research and development unit is also very anxious. For our 099 submarine, I don’t know how many times I have studied it. However, I always feel that if we survey and map If you imitate this submarine, it's too big," said the commander of the base.

All the country’s nuclear submarines are based here. The 091 nuclear-powered attack submarines and the 092 nuclear-powered ballistic missile submarines are all here, but now everyone knows how backward this submarine is. Compared with the 099, that It's just scum, not even capable of duel.

Therefore, the development of a new nuclear submarine is at hand. The question is, what kind of nuclear submarine should we use? The 099 class is inappropriate. The displacement of this nuclear submarine is too large. If you build it yourself, just a nuclear reactor cannot be imitated.

"Yes, the displacement of an ordinary nuclear-powered attack submarine does not need to exceed 10,000 tons, or even more than 8,000 tons." Qin Guan said: "However, as a nuclear submarine, the most important thing is the silent performance. It must have self-circulation. Nuclear reactors, advanced propellers, and even pump-jet thrusters."

This time, just treat it as making up for the old accounts! Qin Guan had already begun to think secretly in his heart. According to Qin Guan's plan, of course, he would exchange a few ships from the submarine cemetery of Xiong Country.

However, the submarine industry in one's own country cannot be abolished. Therefore, exchange is one aspect, and at the same time, self-study is also required. Nuclear submarines are usually underwater. They only come up after returning to the cavern. Therefore, it is difficult for the outside world to find the outline of one's nuclear submarine, let alone the data. This is Qin Guan can safely open the weapon boldly The reason for the exchange system, he is ready to start the exchange again.

However, exchange is one aspect, self-study is also necessary. Now, Qin Guan is already happy to see the progress of the domestic military industry under his own impetus.

I am just a primer, a torch, lighting the entire torch of domestic scientific research progress. If I exchange enough nuclear submarines to make domestic nuclear submarine research and development obsolete, of course it will be inappropriate.

For domestic research and development, the starting point for aiming must be higher. Nuclear submarines are meant to fight underwater, and the reduction of silent performance must be a focus.

"Yes, a quiet submarine can give our submarine soldiers the greatest confidence." Captain Xu said from the side: "However, many of the techniques in it are difficult."

The nuclear reactor of a submarine has a very high heat. Unless the reactor is shut down, the circulation pump of the main circuit needs to be on all the time. This is an important source of noise for the submarine. If the submarine has self-circulation capability, even at low speeds, At low power, it does not need to open the circulation pump, which can also bring great convenience to submarine navigation.

As for the propeller, it can be processed in China. With the progress of CNC machine tools, it is not a problem to process high-precision seven-blade or nine-blade propellers with large skew. However, pump-jet propellers still require time accumulation.

"Yes, it is difficult. Tomorrow, let me go to our nuclear submarine production base." Qin Guan said.

Nowadays, nuclear submarine repairs are built in sheds and carried out internally. However, the production of nuclear submarines is still open in the open. After all, it is not easy to cover the entire slipway. When nuclear submarines are built, various cranes must be operated , When welding, it is even impossible to do it in a closed workshop.

"President Qin, I will accompany you." Captain Xu immediately invited Ying.
