Siheyuan: I eat melons while doing scientific research

Chapter 1216 Opportunities at Qianshan Third Line Factory (5k)

However, Chief Engineer Cheng also had questions he wanted to ask while everyone was here.

"Comrades, I have a question that I want to confirm. What kind of take-off method should this drone use?" It can't be taken off from the airport runway, right? This method has poor simultaneous attack capabilities, is troublesome to use, and has a large number of variables during take-off.

This is also the reason why fighter jets converted into drones are not widely used in practice. The number of sorties they can carry out at one time is severely restricted by the number and distribution of airports, and they have to compete with regular combat aircraft for sortie resources, which makes it difficult for them to operate normally. The fighter jets' basic hovering time also makes it difficult for them to wait for all combat aircraft to take off and launch a coordinated attack at a certain place in the air.

The comrades all looked at Gao Zhendong to see his opinion.

"As for takeoff, I suggest you do three types. The first is to take off from a conventional airport. This goes without saying, but it has its flaws, mainly the problem of occupying runway resources."

After hearing Gao Zhendong's words, the comrades from the Air Equipment Bureau nodded repeatedly. This was indeed a problem, and they themselves hadn't even thought about it yet. The main reason was that no one had experience in large-scale operation of drones. At this time, Gao Zhendong could stand out among all the comrades just by relying on his experience in online arguments in his previous life.

"The second is rail-assisted takeoff with rockets. This way, the aircraft can also take off from the ground, and there are no requirements for airport runways. It is not difficult and the cost is not particularly high."

The comrade from the Air Force immediately brightened up, saying this was a good suggestion. In fact, other comrades could have come up with it, but Comrade Zhendong was generally more systematic and could also sort out the advantages and disadvantages, which was more comfortable.

"The third one requires other things to cooperate, which you all mentioned just now. For example, carry it under the wing of a Tu-4 or Tu-6, and then release it from the air. If this is the case, Chief Engineer Cheng and his team need to pay attention to the release technology. When releasing it from an airplane in the air, the airflow is changeable and the situation is complicated, so we need to consider more comprehensively."

As for transport aircraft, that's too much to think about. To fly a drone of the Firebee's level, you don't need a very large transport aircraft. About the same level as C-130/An-12 will do, but we don't have that now.

The An-12 was supposed to enter my country more than two years later.

"Well... this is also a way, mainly because it can greatly increase the mission radius of the aircraft." The comrade from the Air Equipment Bureau thought thoughtfully. Although we have bought a lot of Be-6s, the mission is also heavy: "What about landing?"

Gao Zhendong said: "For landing, I suggest you just learn the Firebee's parachute. Although there are many flaws, and even if it is a parachute, it is still inevitable that it will be damaged when landing. However, considering that this kind of aircraft is used once for reconnaissance, or can be used once, I think it is enough to make a parachute, mainly because the technology is simple and the price is not expensive."

Both cruise missiles and electronic jammers can be used once, if cost is not a consideration. Cruise missiles can be used in many ways, but anti-radiation missiles are the highest priority. After all, other uses now have good alternatives, especially when Danggui Province lacks reliable medium- and long-range air defense missiles.

Our laser-guided bombs and TV-guided bombs are not vegetarian.

But the empty installation bureau obviously doesn't think this way.

"Is there any other method that is relatively easy and will not cause such great damage to the aircraft?" asked a comrade from the Air Equipment Bureau.

"Then we can either land on the runway, but this is more difficult. To be honest, there is no need for it in a short period of time. Another option is to use an arresting net, which is a net set up at a high altitude to stop the aircraft and then take it down. However, this method is technically difficult. In terms of protecting the aircraft, it is better than parachuting, but not much."

This thing is easy to understand. The comrades from the Air Equipment Bureau looked at the overhaul factory and said, "What do you think..."

Need I say more? Seeing your expression, you just want us to build one at the same time. Chief Engineer Cheng didn't even bother to tell the Air Equipment Bureau about their new ideas. He said resignedly, "No problem. We will also build a blocking and recycling network at the same time."

Gao Zhendong didn't care. He just felt that the blocking net was of little significance. It had a strong flavor of temporary transition and there was not much substantial improvement compared to a parachute.

Seeing the comrades from the overhaul factory bravely shouldering the heavy responsibility, the comrades from the Air Equipment Bureau smiled and said, "Comrade Zhendong, what about the remote-controlled drone you just mentioned..."

Comrade Zhendong just said that there are also drones that can be remotely controlled in real time. The Air Force is now more interested in this!

Unexpectedly, Gao Zhendong shook his head and said, "I think remote-controlled drones are not very useful to you at the moment. Instead, the army can use them more."

The comrades from the Air Equipment Bureau could no longer sit still. They said, "This is not acceptable. We know you are from the Army, but you can't attribute everything that flies in the sky to the Army."

"Comrade Zhendong, what does the Army use this thing for?"

Gao Zhendong spat out two words: "Real-time tactical reconnaissance and artillery calibration!"

"Reconnaissance? We can provide it to them, right?" The comrades from the Air Equipment Bureau did not have the same idea as Hermann Meyer that "everything flying in the sky belongs to me". They simply felt that it was a waste.

Gao Zhendong shook his head: "From the perspective of cost, timeliness, convenience, etc., your reconnaissance aircraft, even unmanned reconnaissance aircraft, under current technical conditions, it is difficult to provide the army with timely reconnaissance during combat. This is not because you are unwilling to do it, but because of technical constraints..."

He carefully analyzed the ins and outs of the matter to his comrades in the Air Force, and the biggest problem was still the airport issue.

Whether it is direct take-off or transport aircraft launch, it is severely restricted by the location of the airport, which will further affect timeliness.

As for rocket-assisted takeoff, judging from the deployment situation of the Air Force, it is actually the same as the above two methods.

"At the same time, due to cost reasons, even if you have an unmanned reconnaissance aircraft, its actual performance is far beyond the limit, so it is not necessary at all. If you want to remotely control it, an unavoidable requirement is to transmit video images with a high frame rate in real time. Under current conditions, due to communication technology, this distance cannot be too far..."

The comrades from the Air Equipment Bureau were somewhat puzzled: "Can't TV-guided bombs be transmitted for dozens of kilometers?"

Gao Zhendong shook his head: "The frame rate of that system is a bit low, and the range is only a few dozen kilometers. Even if we work hard to improve it, it is unlikely to break through 100 kilometers in a short period of time. This distance is useless to you, but it is just right for the army. 100 kilometers is already beyond the scope of the campaign level, which is enough for them."

For remote-controlled aircraft, the remote control range determines the combat range.

Under current conditions, the army doesn't care whether this thing can fly hundreds or thousands of kilometers. For them, the scope of a battle is probably only a hundred kilometers, which is already very large for them.

Therefore, a drone with a combat range of only about 100 kilometers is more than enough for comrades in the army.

"In this case, the drone itself doesn't need to be too big due to the limited remote control distance, because if it is too big, it will be meaningless to fly far."

"Then can we remotely control the drone to launch an air strike within a range of 100 kilometers?" The comrades in the Air Equipment Bureau are not stupid, and they know very well what this thing can do.

Gao Zhendong nodded and shook his head: "In theory, it is possible, but the cost-effectiveness is not high under the current technical environment. Moreover, our precision-guided munitions can basically make our aircraft retreat beyond the enemy's air defense range. It is safe, and the attack efficiency, accuracy, initiative, etc. are far superior to unmanned attack aircraft..."

This is why he is not interested in the reconnaissance and strike UAV for the time being. Firstly, it is technically difficult and unnecessary and not urgent. Secondly, our current manned attack aircraft are relatively safe, and their combat effectiveness far exceeds that of the reconnaissance and strike UAV developed under the current technological level.

In this context, Gao Zhendong is more inclined to tilt limited support to the army's tactical reconnaissance drones and artillery calibration drones.

After all, wars are fought with intelligence, and the accuracy of artillery fire can often determine the outcome of a battle.

The 17-Nation Alliance suffered a lot from our artillery fire on the peninsula.

Although we have few cannons, we can shoot accurately. It's okay to shoot from behind, we even use it as a common tactic.

The accuracy of artillery fire is due to the contribution of the scouts in the front, and the emergence of drones can replace the scouts to correct the impact points of artillery shells.

However, Gao Zhendong did not insist that the Air Force had no use for this thing, but threw out a bait: "Moreover, you can let the comrades in the Army try the remote-controlled drone first. Their requirements are low and the results are quick. When the technology is basically mature, it will not be too late for you to develop the Air Force's remote-controlled drones."

In fact, if the conditions were right, Gao Zhendong would like to get the Air Force to join in, but the conditions are really limited, so he has to save every penny.

Gao Zhendong's words made the people at the Air Equipment Bureau feel very comfortable. Hey, this is a good idea. It's free.

It’s fun to get something for free, but it’s always fun to get something for free.

While he was thinking about it, the chief engineer of the Defense Work Committee was also busy: "Yes, this way the funds are used scientifically and rationally, which can maintain the development of technology without adding too much burden. I also suggest that the army do it first..."

He felt that Gao Zhendong's analysis was correct, and the current remote control distance was indeed of little significance to the Air Force.

The comrades from the Air Equipment Bureau thought about it and nodded, saying, "Well, this is not a bad idea: "Well, okay, let's do it this way for now. If this is the case, we only have one problem to solve now - with the goal we had just now, let's take a good look at the enemy's drone again and study it." The observation requirements for looking at samples with a target and without a target are different. If you look with a purpose, you can see more.

"Okay, okay, let's take a closer look..."

One day later, Qianshan Aircraft Engine Factory.

"Director, this is a letter from the Defense Work Committee." A comrade walked into the office of the deputy director in charge of technology and handed him a printed copy.

Although communication via telephone and email is now more widespread, formal documents like these are definitely better in paper form.

Firstly, it gives you a good reading experience, and secondly, it leaves a mark.

People who often deal with civil servants and public servants know how important it is to leave traces.

The factory manager took a look at it and was delighted: "Go and invite the chief engineer, it's time to do the work!"

After that, he read the documents and muttered to himself: "Well, Commissioner Gao has always been concerned about the development of our Qianshan Third Line construction. As soon as the factory was built, he brought us work."

If the production task has been in a saturated state during the process of factory construction, commissioning, and capacity expansion, then the scientific research task now has almost no clue.

First, their superiors didn’t say what to do, and second, without any instructions from their superiors, they themselves didn’t know what they wanted to do.

Funds and resources are limited, and the comrades in Qianhangfa dare not act rashly for fear of wasting them.

I didn't expect that the conditions for scientific research work had just been met here, and the first scientific research project came so soon.

He looked at a line of words on the document and picked up the phone.

The call was made to another large third-line factory located in the Anshun area, Qianfei Factory. Both factories were important achievements of the Third-Line construction. The two companies had very close business ties and were in similar situations.

There is not enough research work and there are no suitable tasks.

For Qianhangfa, it can't do anything that is too difficult, and it doesn't have anything that is not too difficult.

The same is true for Qianfei Factory.

But this line of words on this document seemed to reveal a ray of hope.

"...Yes, yes, yes, it's me. It's like this, I suggest you go to the National Defense Committee, maybe there will be a scientific research task that you are interested in... Yes, I think it is in line with your current situation... What? Tell you? That won't work, it will violate discipline... Yes, yes! Yes! Just go find him... But let me make it clear first, I am just estimating, I can't guarantee the specific situation... I will go too, yes... That won't work, we can't go together... Haha, yes, you guessed it, our scientific research task has been issued..."

For the deputy director of Qianhangfa, it was quite difficult for him to inform Qianfei Factory of the information but not reveal any substantive content. Fortunately, the other party also understood the discipline and did not keep asking questions.

The line of words that the deputy director of Qianhangfa saw was written like this.

"…research and develop a small turbojet engine for a new type of small UAV…"

This sentence is very clear. In addition to the engine they want to imitate, there must be another object for it to be installed on, which is the "new type of small drone" mentioned in it.

Maybe no one has done this yet. If we tell Qianfei Factory about it, maybe they can get it. More importantly, it looks like a replica product, which is the same for Qianfei Factory and Qianhangfa in their early stages. They are both good topics with moderate difficulty.

His guess was partly right.

There is indeed a new type of drone that needs to be imitated, but the one that is compatible with the engine their factory wants to develop has already been settled.
-
On his way home from leaving the Defense Work Committee, Gao Zhendong suddenly noticed a problem - there were suddenly more foreigners on the street than before.

He had a very good memory and quickly realized the change. But he didn't know where the change came from, so Gao Zhendong decided that if the situation continued to develop, he would ask the Defense Work Committee.

Putting this matter aside, Gao Zhendong leaned back in his seat. He was now on his way to Lou's house.

On the day Lou Shouxing arrived, Gao Zhendong left Lou's house in a hurry without even having time to say a few words because of the arrival of that young comrade. Today he just went there to have a meal and chat with Lou Shouxing casually.

There is no rush to talk about more things now, as Lou Shouxing will stay in the capital for a long time.

As soon as Gao Zhendong entered the door, he saw Lou Xiao'e and He Wu, each holding a child and chatting.

Gao Changhe lay on his future aunt's shoulder, looking at Lou Shouxing beside her, stretching out his little hands and drooling wildly.

Lou Shouxing was full of envy and wanted to hug her, but it seemed that his sister and fiancée didn't give him any chance at all. He could only look at Gao Changhe with envy and drool.

Seeing him like this, Gao Zhendong laughed.

"Brother, I'm here, hello, little sister Wu."

Several people greeted him, the most impressive of whom was Gao Changying.

She immediately became dishonest and tried hard to lean her body towards Gao Zhendong, shouting "Daddy, hug me~~~".

Gao Zhendong happily hugged his little cotton-padded jacket and turned to Lou Shouxing and said, "The higher-ups asked me to tell you something. Thank you."

It's no wonder that Lou Shouxing spent a lot of time just trying to find a way to bring that young comrade back.

It is not appropriate for the National Defense Work Committee to directly thank Lou Shouxing for this matter, but it doesn't matter. It is also good to have Gao Zhendong do it for them. Anyway, for the Lou family, it is enough to express a sufficient attitude to this family. The form is not the most important thing.

Sure enough, Lou Shouxing was very excited, and this sentence was enough.

Putting Gao Changying on his shoulders, Gao Zhendong said to Lou Shouxing: "How long will you stay this time? How are things arranged with Xiao Wujie?"

Lou Shouxing smiled and said, "My parents are arranging things with Xiaowu, so I won't take care of it. I'll be staying longer this time."

Just like when Gao Zhendong got married, the two elders of the Lou family were extremely concerned about this matter. They once again took charge of the matter personally and arranged everything, leaving Lou Shouxing and He Wu with nothing to do.

"Well, getting married does take time," said Gao Zhendong.

What a waste of time. When you were getting married, you wasted your father-in-law's time.

Lou Shouxing shook his head: "It won't take much time to get married, but I have work to do in China this time and I have to attend an exhibition."

"Exhibition?" Gao Zhendong had no idea about this.

"Yes, the exhibition. It's the high-tech product exhibition that was held the year before last. It's scheduled to be held every two years now. This exhibition is very interesting. One of my main tasks when I came back this time is to attend this exhibition."

Gao Zhendong understood. No wonder he saw more foreigners on the street.
