Chapter 2323

This requires special research and development. For example, in the later Han Dynasty, the turbofan-500 is a small turbofan engine with a thrust of 500 kg. This engine has a small volume and good fuel consumption. It can be used as the main power of cruise missiles, UAVs and other aircraft. At present, this type of engine, It should also be incorporated into the domestic development plan.

After all, in the future, it will be the world of UAVs. UAVs do not need too high power, but they have high requirements for long-range and so on. For example, the global eagle of Eagle country, a large UAV, should enter the research and development state in China now.

The development of UAV needs the support of electronic technology. In that era of electronic tube, UAV is a dream. 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. Even if this missile is earmarked for special use, it is OK. However, based on this missile, a series of development needs to be carried out. Shipborne, air launched and land-based cruise missiles form a system. If the length is about six meters, it is the most appropriate, It is also best to control the diameter at about 50 cm, with a range of more than 2000 km, go deep into the inland targets of some countries, and search the enemy from a long distance, so as to avoid getting into danger.

As for the principle of low cost, of course, it should be implemented. After all, this thing is not a shell. If it is used like a shell, no matter how rich countries can afford it, it must be cheap enough.

Qin Guan knew that these words were of little use to the people present. He wanted to find experts from the Academy of space and find a team to develop cruise missiles. Then, he gave them several cruise missiles and asked them to copy them, so as to achieve the best effect.

Anyway, I'm idle in China. I'll go and have a look another day.

As for now.

After Qin Guan's visit, he came to the canteen of the base and had dinner with the people. Captain Xu sat next to Qin Guan and said while eating.

"Now, the construction plan of the last class 091 submarine in our country has been cancelled." when Captain Xu said this, the muscle on Qin Guan's face moved.

Class 091 was the first generation of missile nuclear submarine in China. At that time, the most important role was to solve the problem of nuclear submarine. It had a lot of noise and backward technology. However, it achieved a zero breakthrough, that is, the Navy had a nuclear submarine from now on!

Now, with the rapid development of technology, the technology of 091 nuclear submarine has long fallen behind. Although many data may not be true, there is no doubt that the performance of bear and Eagle nuclear submarines is advanced.

At this time, the follow-up construction of class 091 nuclear submarine was stopped. The construction of nuclear submarine cost a lot. Now, the performance is still so backward. The Navy really has no confidence.

"Yes, our navy is looking forward to a new generation of nuclear submarines. Now, our submarine R & D unit is also very anxious. I don't know how many times we have studied this 099 submarine, but I always think it's too big if we map and imitate this submarine." the base commander said.

All the nuclear submarines of the country are based here. The 091 nuclear powered attack submarine and the 092 nuclear powered ballistic missile submarine are all here. But now, we all know how backward this submarine is. Compared with 099, it is slag. We don't even have the ability to compete.

Therefore, the research and development of new nuclear submarines is at hand. The question is, what kind of nuclear submarines? Class 099 is not appropriate. The displacement of this nuclear submarine is too large. If it is made by itself, only a nuclear reactor can not be imitated by its own side.

"Yes, the displacement of an ordinary nuclear powered attack submarine does not exceed 10000 tons, or even 8000 tons." Qin Guan said: "however, as a nuclear submarine, what it needs most is quiet performance. It needs a self circulating nuclear reactor, advanced screw propeller and even pump jet propeller."

This time, it's just to make up for the old debt! Qin Guan began to think secretly in his heart. According to Qin Guan's plan, of course, he wanted to exchange several ships from Xiong Guo's submarine cemetery.

However, China's submarine industry cannot be abandoned. Therefore, exchange is on the one hand, and at the same time, it also needs self-development. Nuclear submarines are usually underwater and come up only after they return to the cavern. Therefore, it is difficult for the outside world to find the outline drawing of their own nuclear submarines, let alone the data. This is the reason why Qin Guan can safely and boldly open the weapon exchange system. He is ready to start the exchange again.

However, on the one hand, exchange and self-study are also necessary. Now, Qin Guan is happy to see the progress of domestic military industry under his own promotion.

I am just an introduction and a torch to ignite the whole torch of domestic scientific research progress. If I exchange enough nuclear submarines and abandon domestic nuclear submarine R & D, it is certainly inappropriate.

The starting point for domestic research and development should be higher. Nuclear submarines are to fight underwater. We must focus on reducing the mute performance.

"Yes, a quiet submarine can give our submarine soldiers the greatest confidence." Captain Xu said aside, "but many of the techniques inside are difficult."

The heat of the submarine's nuclear reactor is very high. Unless the reactor is shut down, the circulating pump of the main circuit needs to be turned on all the time, which is an important noise source of the submarine. If the submarine has self circulation ability, even at low speed, it does not need to turn on the circulating pump at low power, which can also bring great convenience to the 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 large side inclined propeller. However, the pump jet propeller still needs time accumulation.

"Yes, it's difficult. I'll go to our nuclear submarine production base tomorrow," Qin Guan said.

At present, the maintenance of nuclear submarines is carried out inside the shed. However, the production of nuclear submarines is still in the open air. After all, it is not easy to cover the whole slipway. When nuclear submarines are built, all kinds of cranes have to be operated, and it is even more impossible to carry out welding in a closed workshop.

"Mr. Qin, I'll go with you." Captain Xu volunteered immediately.
