In addition to aero-engines, the next thing to do is Tiangong Technology's aerospace achievements. Although last year, Tiangong Technology only successfully developed two rockets, namely Tiangong-1 rocket and Tiangong-1 rocket. Type 2 rocket.

But even so, since Tiangong Technology developed the first rocket in the second half of last year, until now, in just three months, Tiangong Technology has launched six rockets.

Two of these were launched at the South China Sea launch site, while the remaining four were launched at Tiangong Technology's own launch site.

In other words, since Tiangong Technology successfully developed the first rocket, Tiangong Technology will launch a rocket basically every half a month, and every launch is successful. Such a launch frequency can be described as very At the same time, in terms of success, it has been 100% successful so far. Such an achievement is impressive.

At the same time, in terms of the cost of rocket launches, since the rockets launched by Tiangong Technology have almost all been recovered every time, the cost of launching spacecraft from Tiangong Technology is much lower. It is only one-fifth of the launch cost of the official rocket of the same type.

This makes the officials very keen on Tiangong Technology's rocket recovery technology, and has already made a request to Tiangong Technology to purchase the technology.

Wang Bin naturally agreed to the official's desire to purchase rocket recovery technology. After all, for Tiangong Technology, the current rocket recovery technology is only a transitional technology, and there is nothing wrong with selling it to the official.

What's more, aerospace is not something that one person or a company can play, so this aspect is destined to play with the official. Naturally, the technical improvement of the official is also very happy to see for Tiangong Technology.

In addition to these engines that have been developed, there are also several engine projects that Tiangong Technology is developing and will be completed soon.

These projects are the tg-003 turbojet engine, the tg-wsx2 turbofan engine, and the 500-ton rocket engine of Tiangong Technology.

Among them, the tg-wsx2 engine is exactly the engine that Wang Bin and the others issued a military order like the military a few years ago.

However, the difficulty of research and development of this tg-wsx2 engine was somewhat beyond Wang Bin's expectations. According to Wang Bin's original prediction, this engine was at the end of last year, with Tiangong Technology's engine research and development capabilities, It's almost done.

However, this is not the case. Due to the high requirements of the military for this engine, in the last two months of last year, the development of this engine encountered many difficulties, although these problems were ultimately in the research and development of the professor and others. Thanks to the efforts of the personnel and Wang Bin himself, they were finally resolved.

However, when the design drawings of this engine came out and the trial production of prototypes began, it was already at the beginning of this year, and even up to now, ten prototypes of this engine have not yet been manufactured. According to Wang Bin It is estimated that it will take at least half a month to complete the manufacture of these ten tg-wsx2 engine prototypes.

But no matter what, this engine has finally been developed. At the same time, in terms of design data, it also maintains the consistent style of Tiangong Technology, which is very excellent.

This engine, like the previous turbojet engine, is also a mid-thrust engine.

It is not a large turbofan engine, but although the diameter of the nozzle of this engine is not large, the overall diameter is only about the same as the turbofan engine of an ordinary fighter jet, and even in terms of the basic length of the engine, it is not much longer than the ordinary engine .

But it is such a small bypass ratio turbofan engine that can basically be installed on all fighters currently in service in China, that is, the tg-wsx2 engine, and its thrust has reached a very high level.

Even compared with the turbofan engine of the military fighter jet with the highest thrust in the world, it is not inferior, and it even surpasses it in terms of thrust, and it is also higher in terms of specific thrust.

The tg-wsx2 small bypass ratio turbofan engine is developed on the basis of the tg-001 turbojet engine, so its thrust is naturally much greater than that of the tg-001 turbojet engine , reached the level of 21 tons.

At the same time, the working efficiency of the engine is much better than that of the turbojet engine.

There is also the Tiangong 3 500-ton rocket engine that has been developed almost now. Since the development of this engine is completed, at this time their Tiangong Technology has already manufactured a more powerful carrying capacity than the Tiangong 2 rocket. Rocket up.

According to the design data from the Rocket Lab, the new rocket will be a giant, with a load capacity of about 700 tons. It can be said that such a rocket is already a heavy rocket, so huge The tonnage of this rocket is not low.

Since this rocket is the same as the previous rocket designed by Tiangong Technology, it is a recyclable rocket, so in terms of carrying capacity, it is much smaller than rockets of the same level, but the maximum carrying capacity of low-earth orbit , has also reached about fifteen tons, and at the same time, the carrying capacity on the synchronous orbit has also reached about eight tons.

Although it seems that its carrying capacity is much worse than that of rockets of the same level, this rocket is a recoverable rocket, including the first and second stage rockets and fairings, so if this rocket can really be designed and developed And if the launch is successful, then in terms of the economy of the launch, it is not something other rockets of the same level can imagine.

Although, rockets of the same level have a carrying capacity of at least 18 to 20 tons at this tonnage, and the carrying capacity of synchronous orbits also has a carrying capacity of 10 to 12 tons. However, other rockets of the same level, at one time After use, it cannot be used again, but this rocket of Tiangong Technology is different. Due to the overall recovery, it can be launched again next time, so on average, the cost of each launch of this rocket is at least compared to Other rockets of the same level should save at least four-fifths.

It is also true that Wang Bin attaches special importance to the research and development of this rocket. During this period of time, he has been going to the rocket laboratory almost every day to check the progress of the rocket's development and manufacturing. When there are problems, he also helps to solve them by the way.

You know, if Tiangong Technology has a rocket with such a carrying capacity, then Tiangong Technology will be eligible to participate in several major aerospace projects hosted by officials, not as it is now.

Although a variety of spacecraft have been launched to the government, it can be regarded as joining the ranks of the construction of Huaxia Aerospace Engineering.

But with this rocket, Wang Bin and his team will have more confidence in Tiangong technology, and it will also be able to greatly speed up the progress of these projects in Huaxia. At the same time, the consumption of funds will also be greatly reduced. After all, this year's Huaxia has many large-scale aerospace projects, including the construction of the space station.
