Take Off My Aviation Era

As soon as the voice fell, Hou Yuejin walked to an attack-2 drone and greeted a staff member nearby. The two of them removed the power compartment shell at the rear of the fuselage after three attempts.

Soon, a power unit with a length of less than one meter and a diameter of about forty centimeters was revealed. Hou Yuejin pointed to this power unit and said: "Our wd-30s turbofan engine uses this principle. In addition to the inner duct of the turbine and the outer duct of the fan, we added a duct-like mechanism at the tail nozzle.

In this way, the high-temperature air flow injected backward will induce the ejection effect like a bladeless fan. Under the action of the Venturi effect, it will drive the cold air to be injected along the outer culvert successively, thereby preventing the injected high-temperature gas. Neutralized.

With the 2.86 bypass ratio of our wd-30s turbofan engine, the cooling air injection volume of the engine itself is relatively large, which forms a double cooling effect with the outermost ejection duct, so... Uh... Dear heads... ...I don't know...Is it right?"

In front of the wd-30s turbofan engine, Hou Yuejin suddenly had a kind of talk about his new idea at the group headquarters to a team partner in the business department. It was called a talk, and the result was almost looking up when waiting to talk. The small heart almost didn't stop immediately.

I saw that a bunch of heads, including the head of the headquarters, stared straight at him. The momentum made Hou Yuejin sweat instantly behind him, and at the same time, his mind quickly asked three questions:

Did something go wrong? Isn't there any thoroughness? Oh, what can I do?

As a result, 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 had found nothing. Hou Yuejin was very careful and immediately. Speaking of the throat, my God, I can't really make a mistake, right?

It wasn't until an officer accompanying the chief who came next to him pulled his sleeves and gestured to stand aside, Hou Yuejin realized that he was thinking too much. Where is the focus of the chiefs? It was clearly that one. wd-30s turbofan engine, but he just blocked most of the wd-30s turbofan engine too hard. Who else can the chiefs see if they don't look at him?

Leaving quickly apart from anything else, most of the invisible pressure instantly disappeared, and Hou Yuejin finally let out a long sigh of relief.

However, Hou Yuejin’s pressure was less, and the pressure on the head of the airborne troops was even greater, because the heads of the troops kept looking at him, especially the heads of the navy, with jealous eyes. , Envy and some kind of goodness finally let me see the joy, kneaded together, like a knife, he kept cutting the head of the airborne troops.

Of course, this is not bad. The chief of the only second artillery is more straightforward. Look at the wd-30s turbofan engine, and immediately turn around to look at the commander of the paratrooper. Look at the chief of the paratrooper. , Turn around and look at the wd-30s turbofan engine.

Those sharp and straight eyes can know what you want to express without having to guess, small turbofan engine, okay, old man, you can get this thing, and give me a hundred or so chants for my buddies. ?

It’s no wonder that these leaders are like this. They may not understand those advanced principles of aerodynamics or various calculation methods, but they know very well that a turbofan starts, especially the huge small turbofan engines in front of them. value.

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

It is not how much lightweight materials they use, nor is it repairing the fuselage to perfection, but because they generally use small turbofan engines.

Fuel-saving, light and efficient.

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

Other countries want to catch up. France, for example, can’t do it because cruise missiles are too fragrant. It’s really a matter of seconds to have both nuclear and nuclear weapons. The United States and the Soviet Union have agreed to use them. So France also wants to do something.

As a result, the engine is always difficult to pass.

It is necessary to know that the aero engine is so urinary, it is difficult to get bigger; it is not easy to get smaller, even if it is only one-time, it must guarantee 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 for so long, not to mention a certain life span if necessary. In other words, if it can be recycled, it is simple It can be used normally after maintenance.

This requires this type of small turbofan engine to have the performance no less than that of an ordinary engine, and because each component is small, the manufacturing aspect also needs to be adjusted.

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

Counting the entire earth, the United States, the Soviet Union, and Europe did not develop the so-called "Taurus" cruise missile with the technical support of the United States until long after the end of the Cold War. However, even so, the range and effectiveness of the cruise missile are still a level worse.

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

The domestic situation is similar to that in France. The desire for small jet power is really eager to see. Not to mention, most of the anti-ship missiles in the Navy are rocket engines. Not only are they large in size, they have a limited range, and can only reach 40 kilometers. .

This distance is a little farther than the battleship naval guns of World War II.

The subsequent c-801 was only stronger in size than those old-fashioned missiles, and there was no qualitative breakthrough in range. The subsequent improved c-802 finally achieved a breakthrough due to the use of turbojet engines ~ www.readwn.com ~ range reached More than 80 kilometers.

However, there is still a slight distance from the Navy's target range of more than 150 kilometers.

The Navy also knows that everything can be easily solved by changing to a turbofan engine. The problem is that the country is not as good as France in this respect. In addition, due to the division of labor, the aviation unit responsible for aviation development feels that missiles are aerospace, so they put their energy on large aero engines. on.

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

Under such circumstances, the Navy really has no other choice but to wait.

A similar situation is the Air Force and the Second Artillery Corps, because their air-launched missiles and cruise missiles under development require small turbofan engines to support them. Only in this way can the combat effectiveness and combat effectiveness be improved by several levels, but the result is the same as the Navy There is nothing on it, everything is forbidden.

Now it's all right, the wd-30s turbofan engine of the Ascendas Group is so shyly placed in front of everyone. To be honest, if the leaders of the troops present are not very controllable, their saliva will flow to their feet.
