Chapter 283 They are all flying in the sky, one is tall and the other is short
With the technology and environment of this era, it is unrealistic to engage in photovoltaics on a large scale, but it is like solving the daily scientific research work in the desert. It won’t be a big problem if it uses electricity and a little bit for aerospace in the future.
But don’t even think about centrifuge power supply. When using centrifuges in the desert, it’s not just one or two centrifuges.
Now Gao Zhendong does not know this. He is receiving a confidential call from someone he has not seen for a long time.
——Chief Engineer Wang of LYP-6 Aviation.
General Manager Wang called with only one purpose, asking about tungsten-molybdenum alloy.
"Director Gao, I just received a notification that your factory has released a new material?" This was asked knowingly, but the purpose was not to determine whether the third rolling mill had released a new material, but to confirm whether it was It wasn't Gao Zhendong's fault.
The report only stated which factory did what, but did not include the name of the researcher.
But for General Master Wang, with 591 Pearls in front of him, his first reaction was that this thing was probably written by Gao Zhendong.
So he simply made a phone call. After all, looking at the information in the bulletin, it was clear and direct to ask him directly.
"Well, yes, yes, yes, Mr. Wang, do you have any guidance? I am quite familiar with this material, haha."
The meaning of this sentence is more obvious. I didn't say it directly, but Nothing was said again.
"That's great, I was just about to ask. The bulletin only said that the core melting point reached 2600°C, and didn't mention much else, so I came to ask you, haha."< br>
It seems that it is intended to be used in engines, but I don’t know whether it is LYP-6 or a new engine.
"Mr. Wang, this material has good processing performance and acceptable mechanical strength. However, my opinion is that if it is used on a turbine, it is not recommended to use too much. The specific gravity of this material is a bit high. It’s 17 o’clock.”
Mr. Wang was happy when he heard this: "Haha, as long as the processing and mechanical properties are good, 2600°C is too high for us at this stage, and there is no need to use it on a turbine. You said it is not recommended to use too much. "Really?"
Gao Zhendong said: "If you want to use it, just use the first stage turbine. The weight cost is acceptable, but any more will have a greater impact on the thrust-to-weight ratio."
No. The temperature of the first stage is the highest, and the further it goes, the lower it becomes. It will indeed be used in future aviation engines, but whether it is suitable for LYP-6 or other engines of Mr. Wang and others depends on Professional knowledge.
Mr. Wang pondered for a moment: "I originally planned to use it on things like valves, pipe fittings, nozzles, etc., but your suggestion is not unreasonable. We have to do the calculations to see the pros and cons. How about it."
This Gao Zhendong stopped making random ideas. After all, Mr. Wang and the others are the professionals in this regard. He just said: "Mr. Wang, if you need detailed information, I will contact you right away. Ask the comrades in the confidential office to send you a copy.”
This was the purpose of General Master Wang, and he kept saying hello: "Okay, okay, thank you."
After hanging up the phone, Gao Zhendong immediately started arranging the matter. An hour later, Chief Wang received the data sent.
As for why it was so fast, you have to ask Gao Zhendong himself and the comrades of the Defense Working Committee.
Multiple encryption, trustworthy!
Mr. Wang got the information on tungsten-molybdenum alloy and couldn’t wait to open it and read it.
"Hey, this ratio is a bit high."
"But the performance is also very good. Director Gao really created a problem for me, haha."
Wang The chief engineer was talking to himself and calculating based on the information sent by Gao Zhendong.
Although troubled, but happy.
Fortunately, DJS-59 is here, and all the calculation programs related to using 591 to make turbines are available. Just load them from the tape and modify some corresponding parameters. This is comparable to pulling out a pen and paper and taking It's much faster to get a slide rule and abacus and start from scratch.
While calculating, General Master Wang was impressed by Gao Zhendong's versatility. It was as if he had fallen into his circle. The materials, tools, usage, and calculations all came from him.
After tinkering on the computer for a while, Commander Wang breathed a sigh of relief.
In general, the relatively high melting point and other characteristics of this material make it very suitable for use in turbines, but its heavy weight consumes all the thrust benefits. .
But what Director Gao said is very reasonable. The first stage or the first two stages can be used to increase the temperature in front of the turbine.
Although the density of tungsten-molybdenum alloy is too high, we are not at a loss because we have increased the temperature in front of the turbine, right?
As for the back, when the gas temperature has dropped, you can use 591, which can increase the temperature in front of the turbine without being too affected by the density of tungsten-molybdenum alloy.
After all, the temperature in front of the turbine is not just high. The engine thrust is also affected by many conditions. It can be appropriately increased to a certain level. After preliminary calculations, under current conditions, if tungsten-molybdenum alloy is used as the first-stage turbine, the engine thrust can be increased by several points, and the thrust-to-weight ratio will be slightly increased.
This is amazing. Regardless of a few points, when the technology reaches a certain limit, it will be difficult to extract even one point.
And the thrust-to-weight ratio has also increased slightly, which is even more powerful.
Mr. Wang turned off his computer, closed his laptop, and called Gao Zhendong. This time he did not go through the confidential channel.
The call was finally connected. General Master Wang didn’t say anything else. He just said two words in a confused manner: “Thank you!”
Gao Zhendong knew it well and didn’t When he said nothing else, he just laughed and said: "You're welcome, I hope I can help."
The butterfly wings flapped slightly again, which made Gao Zhendong very happy.
What he is doing now is also flying in the sky, but it is flying lower and it also uses an engine.
——The rocket engine of the anti-tank missile, just say it flies or not.
After reaching a cooperation with the Changjian Machinery Factory and the user, the Changjian Factory has already started to develop the warhead and wire release mechanism. The first step Gao Zhendong is responsible for is the rocket engine.
Considering that the Changjian Factory needs to get the rocket engine for testing as soon as possible, although it will take time for them to make the warhead and pay-off mechanism, Gao Zhendong is still prepared to draw the diagram of the rocket engine as soon as possible, and then use The third rolling mill trial-produced the shell, and the Changjian Factory filled the solid propellant according to Gao Zhendong's design.
Since the two major processes involve transferring the order between the two factories, the procedures and processes may be cumbersome, so Gao Zhendong still tries his best to put this matter up front.
If we take Erkiji as an example, it seems that the solid rocket motor is very simple. There is a shell (qiao, four sounds) on the outside and a bunch of medicine inside.
But once you get started, it's actually more than that. The shell, charge, combustion chamber, nozzle, and ignition device are each divided into several sub-items. They are all high-tech.
Fortunately, what Gao Zhendong wants to do is to fly only a few kilometers, so the difficulty is not bad.
As for why Gao Zhendong also knows a little bit about this, it goes back to the old topic of "networking makes people progress".
In Gao Zhendong's storage, there is a book. The content of the book is about the design of solid rocket motors. He spent 4 lottery opportunities to dig this thing out directly from the system. of.
It was not difficult to get this thing in the previous life, because it was a publicly released university textbook. It can be seen from this that it is obviously nonsense to say that we do not advocate martial arts. It is just that in modern times, the "martial arts" of Shang has changed slightly.
In order to do this job, Gao Zhendong has spent a lot of money. Only more than three months have passed since the system upgrade. He spent 4 times on "TCP/IP Detailed Explanation" and another 4 times this time. The number of draws was not enough. Use it, so Gao Zhendong doesn't dare to draw a lottery.
Fortunately, he still has 6 spares in hand. In his current situation, instead of betting on Europe and Africa, he might as well directly work out a miracle.
Although this book is a university textbook, it is extraordinary in this era. Every chapter in it has been verified by predecessors who have spent countless efforts, time and practice, although there is only one sentence in the book. Words, but to people of this era, every word is precious and weighs more than a thousand pieces.
For example, "Figure x. Just the engine.
Coincidentally, there is a picture in the book, "Picture x.x Citigroup TOW anti-tank missile engine."
Although I wouldn’t copy this thing, with this picture and the various theories in the book, for Gao Zhendong, an anti-tank missile engine is not a big problem.
The advantage of this product is that it also has a structure with a mid-mounted engine, an obliquely cut (obliquely, jetting air to both sides in the middle of the missile body) nozzle, and a tail wire release device.
It coincides with Gao Zhendong’s idea, so its structure has a good reference value.
As for this domestic textbook, why there is no rocket engine structure of the Red Sword-73 with a similar structure? This matter is something everyone understands.
The entire rocket engine design process is still relatively complicated, but Gao Zhendong was in a special situation, and he quickly selected a configuration that was similar to the TOW engine, but also had differences.
After all, a heavy bomb and a light individual bomb.
A vehicle-mounted launcher and a soft launcher in a closed space that need to be considered.
One tube launcher, one pure light rod.
As propellant, he did not hesitate to choose the X12 dual-base propellant of the Citizen Dragon anti-tank missile. Although the Dragon missile has a speed of more than 120 meters per second and a range of 1,000 meters, it is extremely weak. This has nothing to do with the propellant, it's purely the fault of the very bad engine.
No, it's not "that", but "that pile". Have you ever seen a missile with 60 engines, one-to-one relay ignition and flight? This is it. Moreover, this product is an individual anti-tank projectile. On the small projectile body, the engine is so neat that it almost makes people suffer from trypophobia.
