As soon as the words fell, Hou Yuejin walked up to an attack-2 drone, beckoned a staff member next to him, and the two of them removed the power compartment shell at the rear of the fuselage with three strokes and five divisions.

Soon it was revealed that the power unit was less than one meter long and about forty centimeters in diameter, and then Hou Yuejin pointed to this power device and said: "Our WD-30S turbofan engine uses this principle, please see, in addition to the connotation channel of the turbine and the outer duct of the fan, we have added a mechanism similar to the duct at the tail nozzle.

In this way, the high-temperature air jet will act like a bladeless fan, inducing an ejection effect, and under the action of the venturi effect, the cold air will be sprayed along the outer duct successively, thus neutralizing the high-temperature gas sprayed out.

With the duct ratio of 2.86 of our WD-30S turbofan engine, the cold air injection volume of the engine itself is relatively large, so as to form a double cooling effect with the outermost induction duct...... Forehead...... Ladies and Gentlemen...... I don't know...... Am I talking about ......?"

Hou Yuejin suddenly had a kind of team member in the group headquarters to the business department to tell his newly conceived concept, which was called an eloquent talk, but when he looked up, a small heart almost stopped directly.

I saw that a bunch of leaders, including the head of the headquarters, were staring at him so directly, and the momentum made Hou Yuejin break out in a cold sweat in an instant, and at the same time, his mind quickly coldly asked:

Did you go wrong? Didn't you explain it thoroughly? Oh, what can I do?

So Hou Yuejin's voice became smaller and smaller, until he swallowed all the words into his stomach, but the leaders in front of him continued to stare at him as if they hadn't found anything, Hou Yuejin's careful liver immediately raised his throat, God, he couldn't really make a mistake, right?

It wasn't until an officer who accompanied the chief next to him pulled his sleeve and motioned to stand aside, that Hou Yuejin realized that he was thinking too much, where is the focus of the chiefs, it is clearly the WD-30S turbofan engine, and he is so good that he just blocks most of the WD-30S turbofan engine, who else can the leaders look at him if they don't look at him?

Without saying a word, he left quickly, and in an instant, most of the invisible pressure disappeared immediately, and Hou Yuejin finally breathed a long sigh of relief.

However, Hou Yuejin's pressure is small, and the pressure on the head of the airborne troops is even greater, because the eyes of the heads of the troops are glancing at him one by one, especially the heads of several naval units, and the eyes are full of jealousy, envy, and a certain kind of goodness that finally let me see the pleasure, rubbing together, like a small knife, cutting the head of the airborne force one by one.

Of course, this is not bad, the only head of the Second Artillery Corps is much more direct, look at the WD-30S turbofan engine, immediately turn his head to look at him, the commander of the Airborne Forces, look at the head of the Airborne Forces, and then turn his head to look at the WD-30S turbofan engine.

That sharp and straightforward gaze doesn't need to guess to know what you want to express, small turbofan engine, okay, old man, you can get this thing, and give your buddy a hundred or ten, okay?

It is no wonder that these leaders are like this, they may not understand the advanced principles of aerodynamics, and they do not understand the various calculation methods, but they are very aware of the great value of a turbofan engine, especially the small turbofan engine in front of them.

Why did American and Soviet cruise missiles fly so far?

It's not how much light material they use, and it's not that they repair the fuselage to flawlessness, but because they generally use small turbofan engines.

Fuel-efficient, lightweight and efficient.

This is the unparalleled position of the United States and the Soviet Union in the field of cruise missiles for a long time.

Other countries want to catch up, for example, France, there is no way to be too fragrant with cruise missiles, and it is really seconds to have both nuclear and conventional weapons, and the United States and the Soviet Union have said that they are good, so France also wants to do it.

As a result, the engine is always unpassable.

You must know that the aero engine is so urinary, it is difficult to make it bigger, and it is not easy to get it smaller, even if it is only a one-time one, it must ensure a service life of more than 50 hours.

Don't underestimate these 50 hours, at a high temperature of about 1,000 degrees Celsius, not all materials can last so long, not to mention that there must be a certain amount of life redundancy if necessary, in other words, if it can be recycled and used normally after simple repair.

This requires these small turbofan engines to perform as well as ordinary engines, and due to the small size of the individual components, the manufacturing aspects also need to be adjusted.

In short, it is not easy to really make this kind of engine.

It was not until long after the end of the Cold War that the United States, the Soviet Union, and Europe developed the so-called "Taurus" cruise missile with the technical support of the United States.

So France had no choice but to replace it with a small turbojet engine.

The situation at home is similar to that of France, and the thirst for small jet power is really long-sighted, not to mention anything else, most of the anti-ship missiles in the hands of the navy are rocket engines, which are not only large in size, but also have a limited range, which can only hit 40 kilometers at most.

That's a little farther than the battleship guns of World War II.

The subsequent C-801 was only stronger than those old missiles in size, and there was no qualitative breakthrough in range, and the subsequent improved C-802 finally made a breakthrough due to the use of turbojet engines, with a range of more than 80 kilometers.

However, it is still a little short of the range of targets of the Navy of more than 150 km.

The navy also knows that everything can be solved by changing the turbofan engine, but the problem is that the country is not as good as France in this regard, and because of the industrial division of labor, the aviation unit in charge of aviation development thinks that the missile is aerospace, so it puts all its energy on large aero engines.

The Aerospace Forces are specialized in the production of missiles, but they have no experience or foundation in such specialized aviation products as turbofan engines, and can only take one step at a time.

In such a situation, the Navy really has no other way but to wait.

In a similar situation, the Air Force and the Second Artillery Corps both need the support of small turbofan engines for their air-launched missiles and cruise missiles under development, so that they can raise their combat effectiveness and combat effectiveness by several grades.

Now, the WD-30S turbofan engine of Tengfei Group is so embarrassed in front of everyone, to be honest, if the leaders of the troops present are not very strong in their own control, saliva will flow to the surface of their feet.
