The military-industrial scientific research system of the academic master.

Lin Chenggang flipped through the report in his hand twice, but did not see the part he was most concerned about.

So he closed the folder, looked up at Liu Xiyun in front of him and asked:

"Comrade Xiao Liu, you just said... that the previous test failed once?"

In fact, the launch success rate of missiles, especially tactical missiles using solid fuel, is not that high.

For the test standard of this model, hitting the target in six shots is even above the passing line and can be finalized.

However, Lin Chenggang himself was not doing final testing, but using this opportunity to verify the new technology, so he paid special attention to this part.

Liu Xiyun nodded:

"Yes……"

But then he hesitated and explained:

"In fact, if the missile is equipped with a normal radio proximity warhead, then the distance between it and the target should be enough to detonate. However, our test standard is relatively high, and the warhead will only be triggered if the missile hits directly, so we failed to shoot down the target..."

Having said that, he added in a slightly joking tone:

"Of course, if we use the term that's popular recently, it can probably be considered a 'partial success'?"

In the past, technicians would have been singled out and criticized for playing such word games.

But now everyone knows that this is not really shirking responsibility, but is targeting an old rival on the other side of the ocean, so there is no need to exaggerate.

As the saying goes, unity is tension, seriousness is liveliness.

You can't stay tense when you should relax.

For a moment, the entire testing area was filled with a happy atmosphere.

But after all, there was something important going on, so everyone quickly calmed down.

"I mean, why isn't there any mention of this in this report?"

Lin Chenggang became serious again.

Perhaps because his tone was too urgent, Liu Xiyun was slightly stunned.

At this time, Cheng Guangwei, who had been silent beside him, reminded:

"The missile was just recovered about half an hour ago. It still needs to be disassembled and tested before a final attribution analysis can be made."

The former also realized that he was a little too anxious, and the other party had just mentioned that the cause of the accident was being analyzed.

But now that things have come to this, he is still prepared to save his reputation:

"Uh...what about the original data retained during the testing phase? Perhaps we can learn something from it."

Although it seemed a bit absurd for the human brain to analyze raw data, it was not a demanding requirement anyway, so Liu Xiyun gestured to the modified Type 89 armored transport vehicle next to him:

"This is in the command vehicle, follow me."

Lin Chenggang followed the other person and went in through the back door, crouching down.

The sudden dimming of light conditions made it difficult for his eyes to adapt instantly, and it was not until a few seconds later that his vision fully recovered.

The specially raised Type 89 chassis looked like a rather shocking behemoth from the outside, but when Lin Cheng actually sat in it, he realized that the space inside was surprisingly narrow.

Especially after several command consoles are installed on one side of the crew cabin, the remaining space can only barely accommodate 3-4 operators in a crowded manner.

I can't even stretch my legs.

Lin Chenggang, who was tall and strong, felt extremely aggrieved.

While Liu Xiyun and another engineer were searching and exporting data, he carefully raised his hands to protect his head and asked with some doubt:

"Why put the test command vehicle on a site like this... when there is a shelter truck next to it?"

Liu Xiyun typed away on the keyboard, then turned his head with some difficulty:

"Because this is actually a regiment/battalion headquarters vehicle developed for air defense units, which is roughly equivalent to a more powerful 9S737...but we don't have MT-LB, and the cost of the same tracked chassis as the air defense missile is too high, so we used the 89-type transmission with a larger equipment volume."

"Fortunately, our equipment is much smaller than the original one, so it can still be stuffed in. But the commanders will have to suffer a little..."

"The regiment command vehicle..."

Lin Chenggang suddenly thought of the four models being tested outside.

Except for a naval close-in defense missile with a completely different style, the other three can just form a complete air defense network with a range from far to near, which can cover as far as 70-80km and as close as 0 distance directly overhead.

"It seems like you guys are doing something big this time?"

He has somewhat understood——

Although China began to think about the "new three strikes and three defenses" about fifteen years ago, and began to pay attention to the construction of air defense forces like PTSD, when it comes to the big brother of the army, it has been in a state of abandonment for a long time.

Except for a very small number of model units with missiles, the main air defense forces at the division and regiment levels are basically 57mm anti-aircraft guns and 37mm anti-aircraft guns.

And now, the higher-ups should have finally made up their minds and are ready to take advantage of the Olympic security and 0910 project to completely resolve this long-standing problem.

Sure enough, Liu Xiyun nodded and replied with some resentment:

"In the past, it was always the Air Force that got new planes, the Navy that got new warships, the Second Artillery Corps that got new missiles, and the Army that got new recruits... After all these years, it's time for us to get our turn."

The army's equipment is updated slowly, and the people who suffer the most, apart from the front-line commanders and fighters, are the research institutes specializing in field weapons.

Looking at the brother units making huge profits, it is absolutely impossible not to feel envious.

It’s just that the Third Academy of Aerospace Science and Industry Corporation where Lin Chenggang works has always been supported by overseas orders, and even when the army had to endure the period, it had never experienced hard times, so it lacks this kind of feeling.

After finishing speaking, Liu Xiyun seemed to be still a little unsatisfied and wanted to introduce the three models outside to Lin Chenggang.

But at this moment, a crisp prompt sound came from the operating table next to them, temporarily ending the topic between the two.

"Researcher Lin, this is the raw data of the test process."

Liu Xiyun pointed to the densely packed numbers and curves on the screen in front of him and said.

Lin Cheng just took a deep breath and felt a little dizzy.

In fact, this was a method he borrowed from Chang Haonan.

During the research process, the latter often directly bypass the analysis program to check the original test data or the software's work log.

We can often find some conclusions that are easily overlooked in the routine analysis process.

Many times, when things seemed to be a dead end, after several days of brainstorming, we finally saw hope.

But watching others do it is one thing, and actually doing it yourself is another.

Now, facing this huge amount of data that may not even have units, it is difficult to analyze or even read it...

But after all, he was the one who made the request, and it would be too embarrassing if he gave in now.

Lin Chenggang had no choice but to resort to the method he used when he attended academic lectures in his early years as a student. He gritted his teeth and worked through the process, nodding and smiling or shaking his head and sighing from time to time, acting as if everything was under control.

However, perhaps he was indeed influenced by Chang Haonan, or perhaps he was just lucky, but he was able to see some clues.

"Look, it seems like there's something wrong with the secondary ignition process?"

Lin Chenggang pointed to a data group of dozens of consecutive numbers on the screen and said.

Most air-to-air missiles aimed at targets within the atmosphere rely on aerodynamic forces for steering, so the envelope range under no-power and low-speed conditions is usually not ideal.

This happens to be the most common situation before hitting the target.

Therefore, after developing the CTK series of electronically controlled propellants that can freely control the working state, Lin Chenggang's first idea was to retain a portion of the propellant and re-ignite it at the end of the trajectory to improve the control efficiency of the gas rudder.

"Secondary ignition?"

Liu Xiyun was just following instructions and didn't expect to find anything useful.

Are you kidding? If you can identify the cause of the problem with your naked eyes, then why do you need to analyze the program?

As a result, the other party really got it.

Feeling the shocked gazes from the people around him, Lin Chenggang suddenly felt relieved, as if he had become the person in the dream, so he quickly continued to explain:

"Logically, a very close target of 0.8 km does not require a second ignition, but perhaps there is something wrong with the program setting. In any case, a series of new pressurization records still appeared when the propellant did not stop burning, and then..."

The sound stopped suddenly.

It was obvious that despite finding the anomaly, he was still too happy a little too early.

Because logically speaking, even if it is pressurized for the second time, it is impossible to cause the propellant that is in working condition to stop burning.

For a moment, the atmosphere in the command vehicle became somewhat awkward...
