Chapter 976 Comrade Zhendong keeps his word
Apart from these two, the rest can be completed by making some relatively simple additions and subtractions. The main trouble lies in the extent and details of the additions and subtractions. Regarding these issues, Mr. Huang still has full confidence in his unit.

Chief Engineer Gao just needs to give ideas and directions. As for wanting details, that's too much. It's impossible to have details at this stage.

The price paid is a larger radar, better safety, improved take-off and landing performance, a longer combat radius, a wider range of applicability, and potentially a larger payload.

For this fighter, it can be said to be low-cost and high-efficiency.

Gao Zhendong himself actually knows more directions for improvement, but those he is not going to change may have already changed the overall configuration of the entire fighter, which would be a big move.

The main thing this fighter provides is interception capability. The improved take-off and landing performance allows it to be deployed as far forward as possible. With the increased combat radius, it can push enemy aircraft back. With better fire control and radar, that's almost enough. A genuine interceptor can be a one-trick pony that can dominate the field.

As for versatility, there is the new Z-7 and the new G-5 for ground attack, and versatility can be compensated by good avionics. One of the most useful fixed-wing attack aircraft of the Russians in the early days of the Empire Graveyard was the MiG-21R, which was a reconnaissance aircraft and did not even have a machine gun, because it could achieve preliminary "reconnaissance and strike in one" with its reconnaissance pod, although it relied on iron bombs and rocket pods to launch attacks.

Air Force: See, I told you the rocket pod is useful, right?
The real target aircraft is the last model of the "three levels and three types" that needs to complete the task.

For the copied MiG-21, with two upper and lower engines, a good radar and good missiles, plus a certain interception combat radius, it already has enough interception capability against the real future threat Tu-22M. As for the Tu-22, it is a weakling and has no significant connection with the Tu-22M except for the name.

The Russians also know how to use other aircraft to lay eggs. Apart from the name, the Tu-22M and the Tu-22 are completely two different aircraft.

And leaving aside the details of its capabilities, in terms of its operation, the Tu-22M actually does not fly very high, and relies on low-altitude and high-speed penetration to survive. If it is cooperated with an early warning aircraft that can resist ground clutter, the role of this aircraft will be very limited. As for high altitude and high speed, the practical ceiling of this thing is actually not exaggerated, and the maximum is only 18000. As long as the interceptor can fly above 17000, it will pose enough threat to it.

At this time, missiles cannot be used as a panacea in air combat. However, if the target is a bulky bomber, then missiles are indeed more versatile, unless it can launch cruise missiles with a range of hundreds or even thousands of kilometers. In this case, the problem becomes to fight cruise missiles. In the 60s and 70s, the range of the Russians' air-launched cruise missiles did not exceed 500 kilometers, so it was relatively easy to force its carrier aircraft out of range.

When Mr. Huang left the Third Factory with a lot of gains and went to the Defense Work Committee to report his work, the chief engineer of the Defense Work Committee looked at the final improvement plan configuration on their notebooks and laughed.

"Comrade Zhendong really does what he says." He laughed as he spoke, and couldn't stop.

Mr. Huang agreed: "Yes, Chief Engineer Gao does have some ideas for improving the MiG-21, even more in-depth than what he said at the planning meeting."

The chief engineer of the Defense Work Committee laughed even harder, shaking his head as he laughed: "No, no, what I meant is that he said at the meeting that this plane would be ugly. Now it seems that it is really ugly, hahahaha..."

Upon hearing this, Mr. Huang couldn't help but burst into laughter.

After Mr. Huang and the others left, Gao Zhendong suddenly remembered his New Year's Day gains. He couldn't help but pat his head and said, "I forgot, I forgot. I'm still not used to this new gain."

After that, he picked up the phone and called the Defense Work Committee: "... um, yes, yes, I could have gone to find them myself, but now I have too many things to do and I really can't spare the time, so I have to ask them to come... um... yes, yes, it would be best if they could come, some things can't be explained clearly over the phone..."

After hanging up the phone, Gao Zhendong continued to work on the steel material manual with his comrades from the Third Factory. Even if these comrades he had found set out immediately, it would take several days for them to arrive in Beijing. Besides, it was impossible for them to set out immediately after receiving the notice. They still needed some preparation time.

Gao Zhendong came home from get off work. Lou Xiaoe came up to him and took his bag while saying, "You're back? Today, some young people in the yard had a fight with some young people in the alley. Fortunately, the brothers from the back house stopped them. No one else in the yard, young or old, dared to get involved."

Lou Xiao'e always felt that the brothers in the back house looked familiar, but they often seemed to look left, right, and right, so it was always a little difficult to tell them apart.

"Oh? What's going on?" Gao Zhendong was a little worried. A fight? He should be more careful about this matter.

"What else could it be? They have nothing to do. Look at the two guys in the backyard last time. Ever since they got two antenna diagrams from you, they've been running out every day to install antennas for other people. More and more people are buying TVs and radios now, so they're so busy that they have to make some money to survive. It's not the same for those who have nothing to do. If they can't get into a good school or find a good job, they'll be idle all day long. That's going to cause trouble."

Lou Xiao'e said as she patted the dust off Gao Zhendong's body with a towel. These days, people burn wood and coal. The city has not only residents but also factories. It's winter now, so dusting off dust after returning home from outside is very necessary.

"Oh, then don't go too close, someone will take care of it." Gao Zhendong knew that someone would definitely not sit idly by. However, this matter still made him feel that something was wrong. Too many idle people were not a good thing.

He decided to do something.

As for how to do it? He had three chances to search the entire Internet freely. It was time to use them. It would be a waste to keep holding on to them. It was already January 3. The sooner he used them, the better the effect.

And after thinking about it these days, he has already thought of what to use.

He started a search and was very satisfied with the results. As expected, there was a lot of detailed information online about this kind of old thing that was used in large quantities. Maybe every repairman had a set.

This full-network search is no exaggeration, it is a rule-based function, and there are no weak ones under the rule system.

As long as it has existed on the Internet, no matter which country it is from, it can be searched. In his previous life, Gao Zhendong used a certain advertising search engine and other engines to great effect, but the results were not as good as this search opportunity.

People probably won’t put things that are too new online, but compared to Gao Zhendong’s time travel, this thing is too old and has been used too much, so it does exist.

He quickly looked through it in his mind, and yes, this is it. Gao Zhendong put away the whole set of drawings with satisfaction, and went to eat at Lou Xiaoe's invitation.

This thing was not his major or his hobby before, and he had never even seen it. If he hadn't had these three opportunities to search the entire Internet, he would never have been able to get it.

"Chief Engineer Gao, we're here to see you again." Looking at the smiling comrades in front of him, Gao Zhendong was confused. Your noses are too sharp, aren't they? My report hasn't even been sent to the Defense Work Committee yet, and you're here already?

The person in front of him was Engineer Zhu, who was working on satellite electronic systems. He had once come to him regarding the heat resistance of electronic components.

"Hello, Engineer Zhu, what are you doing...?" Gao Zhendong asked with a bit of confusion while greeting them.

"There is a problem with automatic control. You are an expert in this field and have in-depth research on automatic systems, so we came to you." Engineer Zhu said with a smile.

Automatic control system?

Gao Zhendong said with some doubt: "In terms of the functions and technical level of the first generation of satellites in the plan, there are not many related to the automatic system. It is mainly attitude control, orbit maintenance, and some simple automatic control functions, right? Such as taking pictures and transmitting. You should be more familiar with the former than I am, and the latter is simple in function and should not be difficult."

Engineer Zhu gave a thumbs up and said, "You are right. However, we know exactly what to do this time. However, we are not sure about what kind of control system to design to achieve it and what kind of sensors can support our ideas. So I came here specially to ask for your advice."

Gao Zhendong waved his hand and said, "I don't deserve your advice. Let's talk about the problem first."

"To put it simply, we can't take steady photos."

"Because there is not enough electricity? The efficiency of solar panels has reached more than 20% now, that should be enough, right?" As far as I know from my previous life, the original efficiency was not that high, but it was enough.

"It's not entirely a power problem. This is what happened. Our earliest plan was spin stabilization, but we found that the installed capacity of the spin-stabilized solar panels was insufficient. We designed our communication transmission power to be relatively large, so that we can be faster, take pictures more frequently, and send back more pictures. After all, when taking pictures on the other side of the earth, we can't send them back. We can only send them back when we pass over us. As a result, we calculated that the solar panel power was not enough. But this is not the most serious problem..."

Before Zhu Gong finished speaking, Gao Zhendong laughed. "You are trying to stabilize the satellite by spin. You put a circle of solar cells around the satellite so that it can generate electricity normally no matter which direction the sun is in? But you found that the surface area of ​​the satellite is not large enough, and the small solar panels are always partially backlit? And because the slow-scan camera has certain requirements for exposure time, the spin state imaging is not good? But I guess your most serious problem is that the three-axis stabilization is not stable."

There are many types of satellite stabilization, from the simplest gravity gradient stabilization to spin stabilization, and then to three-axis stabilization, the effect and technical difficulty are gradually increasing. Spin stabilization has a rotation speed of about 100 revolutions per minute, which does have a great impact on imaging.
