In Wang Bin's busy schedule, two months have passed in a blink of an eye. It is already the golden autumn of September. Except for the fan engine.

Wang Bin's Tiangong Technology has developed another engine, and like the previous fan engine, the engine developed this time is also a fan engine.

And the channel ratio of this fan engine is larger than that of the engine they have developed before.

Of course, a larger fan naturally means that the thrust ratio of the engine is greater, and naturally the fuel consumption is also greater. However, since this engine is the same as the previous engine, it is also an engine with a large bypass ratio. Naturally, it cannot Let the aircraft fly at supersonic speed. After all, a turbofan engine with a large bypass ratio cannot fly at supersonic speed.

However, as a civil aero engine, it does not want the ability to fly at supersonic speeds. grab grab

In addition, during this period of time, Wang Bin's rocket engine research and development laboratory of Tiangong Technology has finally completed the construction of the rocket engine research and development laboratory of the military's engineering troops day and night, and even the various internal equipment has been completed. Install.

At the same time, the rocket launch pad of their Tiangong Technology has almost been built at this time. According to Wang Bin's estimation, it will definitely not take half a month for the military's engineering troops to complete the construction of the launch pad.

Of course, during this period of time, apart from these achievements in construction, Wang Bin and his company have also achieved achievements in many other aspects. That is to say, the turbofan has accumulated 6,000 hours of test runs at this time, which is almost the same as the life of the tg001 engine that Wang Bin and the others have successfully developed before.巘戅 Yunxuan Pavilion yUnxUangE.oRg戅

However, according to their predictions, the service life of this engine will be far longer than that of the turbojet engine they developed before, at least twice that of the tg001 engine, that is, the first overhaul time is at least It will also be more than 10,000 hours.

If three refurbishments are added until it is scrapped, the full life of this engine is at least 40,000 to 50,000 hours, which means that it is definitely far enough for a civil aviation engine.

And the tg-s2 turbofan engine that has just been developed now, because more advanced technology and better bearings were used in the design, so according to the data, the life of this engine will be longer than that of the previous s1 type Long, according to the data, at least 15,000 hours can be sent.

In terms of turbojet engines, the tg001 engine has undergone continuous improvement over the past two months, and the performance of the engine has also improved qualitatively. First of all, as an engine, it is naturally in terms of thrust.

The improved engine has a maximum thrust of 16.5 tons without afterburner, and the thrust of the most afterburner has reached about 20 tons. With the improvement, the tail nozzle of the engine can also achieve the vector disguise function.

Finally, there is the problem of fuel consumption and engine life. In terms of fuel consumption, although the fuel consumption of the engine has increased after the improvement, the fuel consumption of the engine has increased when the engine is in the cruise state. Bigger, but smaller than before.

In terms of life, as the engine is replaced with better bearings, its life will naturally increase. Although the specific test is still in progress at this time, according to the data, it can reach at least 8,000 to 10,000 hours.

Finally, there is the weight of the engine itself. Although the thrust of the engine has been greatly increased after the improvement, the weight has not increased much.

It's just about a hundred kilograms more than before.厺厽 Yunxuan Pavilion yunxuange.org 厺厽

It can be said that in the past few months, Wang Bin and his Tiangong technology have developed very smoothly. Even in terms of rocket engines, they have completed the research and development of the first engine, and the products they developed are far better than Wang Bin expected. Much better.

Originally, Wang Bin thought that even if he had already purchased a rocket engine from the system, and it was still a complete model, but with the current level of human civilization on Earth, it would still be difficult to develop an engine of the same type as that of cutting stars. of.

However, this is not the case in fact. The data of the first engine developed by Tiangong Technology this time is stronger than the thrust of the same engine that cut stars, because Wang Bin said from the system that the first small thrust he bought The thrust of the rocket engine is less than 300 kN, that is, less than 300 tons.

However, the small-thrust engine developed by Wang Bin and his Tiangong Technology this time is similar to the star-cutting engine in terms of structure, etc., but in many respects, the materials used by Tiangong Technology are different. , The thrust of this rocket engine developed this time has actually reached 350 kN, which is 350 tons, which is more than 50 tons more thrust than the star-cutting one.

However, the engine developed by Wang Bin and his Tiangong Technology has its own defects compared with the same type of engine in the star-cutting world. The rocket engine in the star-cutting world is at least the same as the aircraft engine, and it takes thousands or even tens of thousands of hours.

This time, the engine developed by Wang Bin's Tiangong Technology this time, if it is used at the maximum thrust, it will only last for more than half an hour.

Of course, this level is already very good compared with the same type of engine in the real world. After all, the use time of the same type of engine in the real world is calculated in seconds under the condition of maximum thrust. of.

Of course, just having a liquid rocket engine is not enough if you want to launch satellites, etc. There are also rocket bodies, rocket steering systems, rocket control systems, and so on.

But fortunately, during this period of time, apart from the first rocket engine developed by Wang Bin and his Tiangong Science and Technology Rocket R\u0026D personnel, the research and development work in these areas has made very good progress, and basically completed the research and development. .

And the first rocket has also entered the construction process, and it won't take long to complete the construction.

In other words, now they only need to wait for the completion of the rocket launch pad of their Tiangong Technology, and their Tiangong Technology can launch the first rocket.

However, the launch of the rocket is naturally impossible to launch without a load, and it also needs a carrier. However, due to the very limited load of this rocket of their Tiangong Technology, the load of the low-earth orbit is only a mere 0.5 tons of load.
