Siheyuan: I eat melons while doing scientific research

Chapter 1226: Not only copying, but also new research (4k)

Good stuff. Gao Zhendong weighed the two shells in his hand and asked, "How powerful are they?"

This is what he cares about most.

"35mm target plate, 45 degrees, and a penetration rate of 75%." Professor Liu said it lightly, but Gao Zhendong could hear his pride.

This data is indeed quite good. The armor penetration depth of the Citigroup's 20*102 is 19mm/45 degrees, and the 25*165 is 35mm/45 degrees, which is still good. In short, under the premise that there is no essential difference in materials and propellants, we are still used to using large charges to alleviate the fear of insufficient firepower. For example, the armor-piercing shells of our later 14.5 anti-aircraft machine guns are at the same level as the Citigroup's 20mm gun.

With this penetration, when facing all current Western tanks, there is almost nothing that cannot be penetrated except the front.

Adding the mobility of the infantry fighting vehicle and the firing rate of the 25mm gun, Gao Zhendong laughed. The comrades in the army who used infantry fighting vehicles must be very happy.

"Are the comrades from the Land Equipment Bureau very satisfied?" Gao Zhendong said with a smile.

"Yes, they are very satisfied. Without waiting for our 625 anti-aircraft gun to be completed, they have already asked the Third Line Arsenal in Shuangqing to start producing this bullet. You have the first batch in your hands." Professor Liu nodded. The arsenal in Shuangqing is basically the result of the Third Line construction. It is a new factory that can be put into production directly, which is easier than switching production at the old factories in the east, north, central and northeast.

"Okay, thank you. This is really a good stuff. I'll take it away." Gao Zhendong weighed it in his hand a few more times and turned around: "No, that's not right. My son and daughter have it, but why don't I have it? Hurry up, get me another one thousand or two thousand." This is the famous scene in Journey to the West where Monkey King acts like a rogue.

"One thousand or two thousand? Do you think that Monkey King in Journey to the West asked Laozi for the elixir? Come on, I'll give you two more. There's no more." It seems that Professor Liu has been reading Journey to the West for many years.

At about the same time, at the Northeast Aerospace Engine Research Institute, a group of comrades were circling around an engine, their eyes shining.

The engine looks a bit broken, but the basic appearance is well preserved.

This is a "water bubble machine" that has been soaked in sea water.

This is not a bad thing. Although there is not much difference between touching the water surface and touching the ground at high speed, once entering the water, the damage to the internal parts of the falling object will not be as great as that on the ground, and it will not burn, and can retain its original appearance to the greatest extent.

Like Professor Liu from Beijing University of Technology, Mr. Wang from Northeast Aerospace Engineering Institute also received a gift from F-105. The frogmen tried every possible way underwater and finally fished this treasure out.

As the largest single-engine aircraft ever built by the United States, the F-105's J75-P-19W engine is naturally extraordinary. Although it is very heavy and has a low thrust-to-weight ratio, it has great thrust!

The intermediate thrust is 7.16 tons, the afterburner thrust is 10.88 tons, and the waterjet afterburner thrust is 11.8 tons. If you ignore the weight and volume, this thing is on the same level as the large thruster in the 80s.

The biggest problem is that it is too big and too heavy. It is 6.6 meters long, 1.1 meters thick and weighs 2.7 tons, which is far superior to the R-25B-15 used by the famous MiG-300.

But no matter what, the thrust of this thing is really great, and the problem of being overweight is not too exaggerated overall in this era.

"Mr. Wang, should we report this to our superiors and ask them to copy it?" Not only Mr. Wang, but even other comrades were also tempted.

Mr. Wang’s reason suppressed his impulse: “We need to survey and research what needs to be surveyed, but whether to copy or not is not something we should consider. This engine is too big and too heavy, and we can’t find an engine to install it on.”

"But I remember when we visited Commissioner Gao Zhendong, he also mentioned that things like engines don't necessarily have to have an installation target, they can also be developed," said the comrade who made the suggestion.

President Wang tapped him on the head with the notebook in his hand and said, "Do you think I don't know? But the engine project itself cannot be approved because we still lack money. But we can study this engine carefully. Maybe there are some tips and tricks that can be used in the second phase of our R-13 engine improvement."

Regardless of whether you imitate it or not, it’s always a good idea to use the tape measure first.

At this time, a comrade came in with a smile and said, "Boss Wang, the comrades from Qianhangfa who were assigned to Qianyang, the third line, are back to visit their families."

"Ah? Really? That's great. Come on, let's entertain them. The conditions in Qianshan are much more difficult than ours. We have to give them some money when we go back to my mother's house."

The conditions in Qianshan are not good, this is an objective fact, but this time the comrades from Qianhangfa went back to their mother's home not to replenish their bodies, but to replenish their brains.

To learn how to copy the small turbojet engine, they had to go back to their mother's home for advice.
-
Since the comrades from Qianhangfa had all arrived at the Northeast Aerospace Development Institute, naturally, the comrades from Qianfei Factory, who had set out not long after them, also hurried over and arrived at Gao Zhendong's place one after the other.

Gao Zhendong had just put down the phone when the Defense Work Committee informed him that the comrades working on the satellite would be arriving soon and asked him to stay for the next few days in preparation for the meeting. The comrades from the Internal Security Department of the Third Factory then informed him that the comrades from the Qianfei Factory had arrived.

The big bags they brought had been taken by the internal security comrades. It was not a good idea to bring all these things to work. But Gao Zhendong could even smell the smell of the comrades' wormwood, which made him feel very familiar. There was no way, the characteristics of this thing were too obvious, and it could not be dispersed for a while after it was put down.

"Comrades, please sit down!" Gao Zhendong was very enthusiastic, but when he saw the faces of the comrades who came, he was a little dazed for a moment.

"Comrade, have we met before?" Several people looked familiar.

The visitor smiled and said, "Yes, Chief Engineer Gao, my last name is Jian, a simple Jian. When we were still in the aircraft factory design institute in the northeast, I came to visit you with our boss."

Those who work on aircraft, like those who work on missiles, are the defense engineering system units that Gao Zhendong deals with the most. No wonder they look familiar.

"Haha, hello, Mr. Jian, it really is fate. Now that you're in the Third Front, the tasks on your shoulders must be heavier, right?" Going to the Third Front was not like being exiled. When the Third Front was being built, the policy was "Good people and good horses go to the Third Front." Under normal circumstances, those who could go to the Third Front were all backbones.

"Good people" refers to the backbone, and "good horses" refers to the best machinery and equipment. "I don't deserve the title, Chief Engineer Gao. You should just call me Engineer Jian. I came here this time because I have a heavy burden on my shoulders, so I had to bother you." Chief Engineer Jian said modestly.

Gao Zhendong thought about it and felt that there seemed to be something wrong with the abbreviation he used. The key point was that the comrade's surname was "Jian". After several decades, the homophonic pun would be punished by fines, so he gave a discount.

"Chief Engineer Jian, you are too polite. It's all work. Are you here because of the imitation drone this time?"

In fact, it was not until Gao Zhendong asked this question that the comrades at the Qianfei Factory Design Institute knew what was going on. The comrades at Qianhangfa were bound by discipline and were vague in their response.

Chief Engineer Jian's mind turned quickly, and he went straight to the point: "Yes! That's it. As a newly built factory, we really hope to be able to undertake related tasks. Although the factory is still under construction, our Qianfei Design Institute can already start work..."

The construction of an aircraft factory naturally cannot be completed overnight, but the design institute has lower requirements, especially now that aircraft are relatively simple, and work can indeed be carried out.

As Chief Engineer Jian spoke, his mind raced, organizing in his head all the similarities between the drone imitation and Qianfei's design, thinking as he spoke.

"We think that we can't wait until the factory starts to operate before we start work. That would be a waste of time, and the time of a group of designers would also be wasted, which would cause great losses to the country. We also know that our technical strength is weak, and we can't do anything big at once. Fortunately, drones are not big in size, and there are no major safety hazards for personnel. In addition, imitation is less difficult than new development, which is just right for our group of inexperienced comrades to get familiar with the work..."

You know what, Chief Engineer Jian is worthy of being the chief engineer. His mind is really quick and the reasons he gives are very coherent and reasonable.

Gao Zhendong smiled and nodded: "Well, it does make sense. This matter is indeed quite familiar to you."

The current situation is that the Northeast Institute is working on an improved version of the MiG-21's submandibular air intake, the Southwest Institute is working on a canard air superiority fighter, the Northwest Institute is working on large aircraft, and the Porcelain Institute is working on further optimization of the Z-7 multi-purpose fighter. All of them have their own tasks, and for the time being, their difficulty and importance are higher than this UAV. The comrades working on the Z-5 target are mainly working on program-controlled UAVs, so there is really no aircraft design institute suitable for working on small remote-controlled UAVs.

The remaining one or two institutes are all engaged in helicopter training aircraft, which are even less relevant.

However, Gao Zhendong still asked: "I remember that your original production task was to produce MiG-21 imitation models, right? This is a small drone." But later it became the main production of its training model.

It turned out to be a small drone? I understand: "Yes, there is such an arrangement, but we think there is no conflict between the two. Moreover, the difficulty and resources required for the production of small drones are simpler, and we don't need a complete factory to be built before we can start production. Moreover, the older brothers of the Northeast Institute are still working on the improved model of the MiG-21. We have to wait for the factory to be built and the improved model to be successfully built, and waste the parts that have already been built. We feel really sad."

Qianshan Aircraft Factory is not just one factory. It has a total of 50 subordinate units and 70 engineering projects. It will take a lot of time to complete the construction. At least it cannot start producing fighter jets now, and their production objects have not been determined yet.

I have to say that Chief Engineer Jian’s consideration is very reasonable. Not being able to produce fighter jets does not mean that we cannot produce simpler drones.

Drones do not need to consider multiple subsystems such as personnel support, cockpit, and safety. They have higher requirements for reliability but not so high requirements for safety, which is just right for newly built factories like Qianfei Factory.

"Well, what you said makes sense. Tell me, what are your thoughts on drones?" Gao Zhendong felt that his comrades had given this matter sufficient thought. From a broad perspective, there was no problem. Let's just discuss their specific ideas for doing things.

Chief Engineer Jian was stuck for a moment. He had just been following Chief Engineer Gao's words, but he had never considered the drone. Even before this, he was not sure what he was going to copy. It was fine to follow Chief Engineer Gao's words about the general direction. Generally, there would be no mistakes, and it would be close to reality and meaningful.

However, this method cannot be used when considering a specific type of aircraft, as it is easy to make mistakes.

"Well... Chief Engineer Gao, to be honest, before this, we were not sure what we were going to do, let alone drones. So I dare not answer your question at the moment. Either you let me think about it, or I will listen to your instructions first..." Chief Engineer Jian was very frank and told everything.

Gao Zhendong laughed. He liked it this way, being realistic and leaving no room for misjudgment.

"Well, it's okay. This thing is indeed relatively new. It's not your fault that you didn't consider it for a while. It's normal. So, let me introduce you to the drone and what tasks it has..."

Gao Zhendong explained the relevant contents about remote-controlled drones to Chief Engineer Jian and others.

"Chief Engineer Gao, I understand. If we want to copy this aircraft, we want to make it into a remote-controlled drone, right?"

Gao Zhendong nodded and shook his head: "This aircraft is copied. Because of its long range, it is mainly used as a program-controlled drone for the time being, because the remote control range is not enough..."

Ah? It seems that there is no hope. Aren’t there people who are already making remote-controlled drones?

Seeing that they were a little frustrated, Gao Zhendong changed the subject: "But don't be discouraged. Program control is program control, and the fuselage can still be handed over to you to copy. After you successfully copy the fuselage, you can hand it over as a part to the comrades who are engaged in program control drones for integration."

Compared with the Air Force Fighter Overhaul Factory which is responsible for the overall work of programmable UAVs, the comrades from the Qianfei Institute are more suitable for imitating the Firebee. After all, these are technical backbones transferred from design institutes such as the Northeast Institute. Whether it is new design or imitation, they have advantages over the comrades in the overhaul factory.

Hearing what Gao Zhendong said, Chief Engineer Jian and the others were delighted. Chief Engineer Gao indeed looked at Qianshan in a different light.

"But as for the imitation of this aircraft, you can just copy it directly. I won't give any suggestions. For the specific matters, you can go to the Defense Work Committee and see the wreckage of the Firebee UAV and you will know how to carry out the work. What I want to tell you is another kind of aircraft, not a copy, but a newly developed remote-controlled UAV!"

Newly developed? Or a remote-controlled drone?
This unexpected surprise made the comrades at Qianfei Institute eager to try it out, but also a little worried.

"Chief Engineer Gao, new research? Will we delay things?"
