Chapter 592

As soon as the words were heard, Hou Yuejin went to an attack-2 UAV and called a nearby worker. The two of them removed the power cabin shell at the rear of the aircraft.

Hou Yuejin pointed to the power unit, which was less than one meter long and about 40 cm in diameter, and said, "this is the principle used in our wd-30s turbofan engine. Please see, in addition to the inner duct of the turbine and the outer duct of the fan, we have added a duct like mechanism at the tail nozzle.

In this way, the high-temperature air injected backward will induce the injection effect just like the vaneless fan. Under the effect of Venturi effect, it will drive the cold air to inject successively along the outer culvert, so as to neutralize the high-temperature gas injected out.

With the bypass ratio of 2.86 of our wd-30s turbofan engine, the cold air injection volume of the engine itself is relatively large, thus forming a dual cooling effect with the outermost injection bypass Well Heads I don't know Do I mean... "

Facing the wd-30s turbofan engine, Hou Yuejin suddenly talked about his new idea to a group of team members in the group headquarters. It was called a talk. As a result, he almost looked up and saw that a small heart almost didn't stop immediately.

A group of leaders, including the head of the headquarters, were staring at him. The momentum made Hou Yuejin break out in a cold sweat. At the same time, he asked three questions in his mind:

What's wrong with him? Isn't there anything that hasn't been thoroughly explained? Oh, what can I do?

So Hou Yuejin's voice became smaller and smaller until he swallowed all his words. However, the leaders in front of him continued to stare at him as if they had not found anything. Hou Yuejin's careful liver immediately raised his voice. Oh, my God, can't he really make a mistake?

It was only when a nearby officer who accompanied the chief pulled his sleeve and motioned to stand aside that Hou Yuejin realized that he was thinking too much. It was clear that he was the focus of the leaders, and he was so stubborn that he just blocked most of the wd-30s turbofan engine. Who else could the leaders look at without looking at him ？

Leave quickly without saying a word, instantly that kind of invisible pressure immediately dissipated most, Hou Yuejin also finally is a long sigh of relief.

However, the pressure of Hou Yuejin is less, and the pressure of the airborne army chief is greater, because a group of army chief's eyes keep glancing at him, especially several navy army chief's eyes with envy, envy and some kind of good, finally let me see the happy, knead together, like a small knife, cutting the airborne soldiers The head of the army.

Of course, this is good. The only commander of the second artillery is more direct. Take a look at the wd-30s turbofan engine. Immediately turn around and take a look at the commander of the airborne. Take a look at the commander of the airborne. Then turn around and take a look at the wd-30s turbofan engine.

You don't have to guess what you want to express. Small turbofan engine. OK, old man, you can get all these things. You can give me a hundred or ten, OK?

No wonder these leaders are like this. They may not understand the advanced principles of aerodynamics and various calculation methods, but they are very clear about the great value of a turbofan engine, especially the small turbofan engine in front of them.

Why can the cruise missiles of the United States and the Soviet Union fly so far?

It's not how much lightweight materials they use, nor how much they make the fuselage perfect, but because they generally use small turbofan engines.

Fuel saving, light and efficient.

This has long been the unparalleled position of the United States and the Soviet Union in the field of cruise missiles.

Other countries want to catch up, such as France. They can't help but have cruise missiles. It's a second to have both nuclear and conventional missiles. The United States and the Soviet Union have agreed to use them, so France also wants to do it.

As a result, the engine always fails.

We should know that aeroengine is such a urine, and it is hard to make it bigger; it is not easy to make it smaller, even if it is only one-time, we should ensure the service life of more than 50 hours.

Don't underestimate these 50 hours. At a high temperature of about 1000 degrees Celsius, not all materials can last so long. What's more, if necessary, there should be certain life redundancy. In other words, if it can be recycled, it can be used normally after simple maintenance.

This requires that this kind of small turbofan engine has the same performance as ordinary engine, and because each part is small, the production and manufacturing also need to be adjusted.

All in all, it's not easy to really make this kind of engine.

The United States, the Soviet Union and Europe did not develop the so-called "Taurus" cruise missile until long after the end of the cold war with the technical support of the United States. However, even so, the range and effectiveness of the missile are still one level lower.

So France has no choice but to use a small turbojet engine instead.

The situation in China is similar to that in France. The desire for small jet power is really overwhelming. Among other things, most of the anti-ship missiles on the Navy's hands are rocket engines. They are not only bulky, but also have limited range. They can only hit 40 kilometers at most.It's a little bit farther than the battleship guns of World War II.

After that, the c-801 was only better than those old missiles in volume, and there was no qualitative breakthrough in range. Due to the adoption of turbojet engine, the later improved C-802 finally made a breakthrough, with a range of more than 80 km.

However, it is still a little short of the range of the Navy's target more than 150 kilometers.

The Navy also knows that everything can be easily solved by changing the turbofan engine. The problem is that China is not as good as France in this respect. In addition to the industrial division, the aviation units in charge of air launch feel that the missile is aerospace, so they all concentrate on the large aero-engine.

The space force is a professional manufacturer of missiles, but it has no experience and foundation in the professional aviation products such as turbofan engine, so it can only take a step at a time.

Under such circumstances, the navy has no choice but to wait.

Similarly, the air force and the Second Artillery Force need small turbofan engines to support their air launched missiles and cruise missiles under development. Only in this way can their combat effectiveness and combat effectiveness be improved by several levels. However, like the Navy, they have nothing to talk about.

Now, the wd-30s turbofan engine of Tengfei group is put in front of the public in such a shy way. To be honest, if not for their strong control, the heads of the troops on the scene would be salivating.
