Chapter 1024

Hearing that Zhuang Jianye was so shameless, the head of the headquarters almost blurted out that he had never seen such a brazen person.

But as soon as the words came to his lips, the head of the headquarters suddenly swallowed them back. It's not that he didn't want to say them, but it's useless to say them. How dare a shameless person say that he has the cheek to hand over the goods to the state, and he's afraid of being pointed at by the nose and scolded for being shameless?

There's no cheekiness.

So the head of the headquarters smoked for a long time and said, "wait until you go back to study."

"No, chief, what else to study? Just a word from you. Otherwise, I won't have the cheek. You can bear the expenses. "

The head of the headquarters almost didn't feel embarrassed by Zhuang Jianye's words. What's shameless? He has to bear more funds. I dare you. Zhuang Jianye is really shameless.

As a result, the head of the headquarters was preparing to go back to the headquarters without any consideration. However, Lao Mu's excited voice came from the air to ground radio station: "this helicopter can't feel like a helicopter when it flies. It's almost the same as the fixed wing aircraft I flew in my early years, and even better in some aspects. Oh, by the way, listen to the pilot next to me, this direct-12 engine is not suitable It was the earlier wd-40b turboshaft engine, but it was equipped with a brand new wd-30c turboshaft engine. It is not only 59 kg lighter than the wd-40b, but also 886 kW in power. So what do you call it

"Steel cannons in the air." There was a cramped and nervous answer on the radio, and then Lao Mu laughed heartily: "yes, it's a small steel gun in the air. That's a great name."

"Please pay attention to your flying posture, 01! Your turning radius is a little too small to stall easily. " Just when Lao Mu let go of his flying experience, the ground commander let Lao Mu go back with a word.

However, the head of the headquarters looked at Zhuang Jianye with a puzzled look on his face: "I remember that the maximum power of your wd-30 series turboshaft engine is only 569 kW, how did it rise to 886 kW all of a sudden?"

"Yes, the new alloy x turbine blade on our third generation core machine has made a substantial breakthrough. Alloy x alone can withstand a high temperature of up to 1300 degrees Celsius. With film cooling, ceramic coating and other technical means, the maximum temperature can reach 1587 degrees Celsius."

"1587 degrees centigrade!"

Hearing this number, Rao, the head of the headquarters, has been numbed by the technical background of Tengfei group, but he is still shocked by this number.

1587 degrees centigrade, equivalent to 1860 Kelvin.

At present, the total temperature of F110 small bypass ratio turbofan engine equipped on F-15 and F-16 in the United States is only 1650 Kelvin, which can be converted into 1378 degrees Celsius, which can provide powerful power.

Even if the new f-119 small bypass ratio turbofan engine equipped with the F-22 fighter plane to be put into mass production in the United States, the turbine front temperature is only 1900 Kelvin. Based on this, the feat of f-119 afterburner thrust approaching 17 tons was created.

With this comparison, the significance of 1587 ℃ obtained by the new alloy x combined with various cooling and heat-resistant technologies is self-evident.

The surging heart of the next generation of combat aircraft in the "Assassin's mace" plan has been found.

This alone is enough for the head of headquarters to be excited all day.

"How did you do that?" Suppressing the impulse to jump up in place, the head of the headquarters asked.

"You asked about alloy x?" Zhuang Jianye looks at the head of the headquarters with innocent eyes.

"Is it y?" The head of the headquarters was in a good mood and couldn't help laughing.

As a result, Zhuang Jianye really nodded seriously: "yes, but alloy y is not in the field of aviation, but in the field of aerospace. At present, we are going to apply it to the fuel nozzle of satellite. After testing, the service life of satellite nozzle using alloy y is increased from 1 to 2 years in the past to 12 to 15 years."

"Poof ~ ~"

when he said this, the head of the headquarters just took the tea cup from the guard, sipped it and listened. The life of the satellite tail nozzle was increased by more than 10 times, and it was sprayed immediately.

"Cough ~ ~ ~ how much do you say? The life of the nozzle has been increased to 12 to 15 years? " The head of the headquarters coughed for a long time before he calmed down and asked.

There is no way. Compared with the previous alloy x, alloy y, which is usually taken out of joke, is really beyond the expectation of the head of the headquarters. Even so, it does not hinder the great potential and application value of this alloy.

We should know that satellites in space, especially some high-value reconnaissance and communication satellites, will carry a certain amount of boost fuel. On the one hand, the orbit can be changed in time according to the needs of the ground, so as to provide better communication services and fixed-point reconnaissance for specific areas; on the other hand, the most important thing is to resist the orbit deviation caused by regional gravity, so it is necessary to change the orbit at a specific time and time It is necessary to revise the orbit in order to maintain a high quality orbit so as to better carry out the outer space mission.In the past, due to the space environment and the high-temperature effect of fuel, the life of the tail nozzle decayed very quickly. It lasted for about one or two years, and the tail nozzle could not be used. As a result, the satellite could not correct its orbit in time, and its performance declined rapidly, so it had to give up.

Now with alloy y, the service life of the tail nozzle has been increased by 10 times, that is to say, as long as the internal systems of a satellite do not have accidents, the service life can be increased to more than 10 years.

In this way, the cost performance of the satellite will be greatly improved, while providing a more flexible operation scheme for ground operation.

Let's not say anything else. In the past, when we saw who was upset and wanted to insert a space eye, we had to design the orbit, calculate the synchronization parameters, and then launch a geostationary satellite.

If the satellite with the tail nozzle made of alloy y by Tengfei group is applied, it will not be so troublesome. The ground control station only needs to give the satellite a command of orbit change, and it can easily fly to the top of a home. You can see what you want.

What? What about being found?

Come on, it's in outer space. Hey ~ ~ ~ it's an honor for your family to avoid space garbage and stay in this safe area for a while.

Of course, this is only an application scenario of alloy y. since it can be used in the fuel tail nozzle of satellite, there will be no obstacle in the long-range launch vehicle; since it can be used in the long-range launch vehicle, there will be no problem in the long-range land-based missile and the long-range sea-based missile.

You should know that all the things that can be used on satellites are lightweight. Such lightweight high temperature resistant materials can be used in products such as long-range launch vehicles, which can improve the load immediately.

It was only when he realized this that the head of the headquarters was shocked. However, the head of the headquarters did not say anything about alloy X and Y. instead, he looked at Zhuang Jianye and continued to ask, "so there is alloy Z?"

"Yes, there is alloy Z." Zhuang Jianye did not hide.

"What's this alloy Z for?" Asked the head of the headquarters.

"This..."

"What? Is there no progress? " Seeing that Zhuang Jianye hesitated, the head of the headquarters frowned, but he shook his head and said pitifully, "it's not that there is no progress, but that there is no funds!"

The head of the headquarters is full of black lines!
