Siheyuan: I eat melons while doing scientific research

Chapter 1201 Infectious Diseases in the Research Institute (4k, 5k in the early morning)

New Year’s Day is not a weekend, but it is a holiday.

Gao Zhendong doesn’t know whether others will let him go or not, but he wants to let him go. He should work when he should work and rest when he should rest.

He and Lou Xiao'e took Changying Changhe and went to the temple fair.

He was having a good time, but other comrades were not so idle.

In the suburbs of Beijing, at an experimental base of the Missile Research Institute, comrades are testing the telemetry bomb of a missile.

This missile is exactly the short-range air defense missile in the integrated missile and artillery system proposed by Gao Zhendong. The artillery of the integrated missile and artillery system is produced by Beijing University of Technology, the radar is produced by the Radar Institute, and the short-range air defense missile is developed by the Missile Research Institute.

It is said that based on the work of the Missile Research Institute, it has gained enough experience in the development of semi-active radar missiles. Such a small missile should not have too many problems. At least the speed should be fast enough. Not to mention the hit rate, at least the flight telemetry missile of this missile should be developed quickly.

However, the reality seems to be otherwise.

"Failed again!" The comrade from the Missile Research Institute slapped his thigh as he looked at the missile smoke trail circling in the sky.

In their view, the missile's tail smoke meant "going around in circles in disgrace."

"The probability of this missile becoming unstable is too high. Something must be wrong here." A comrade looked at the track in the air with his brows furrowed.

This thing doesn’t look very big or complicated, so how did it become like this?

"Is it a problem with the rocket engine?" another comrade analyzed.

When a missile becomes unstable, the first thing to be suspected is the engine. After all, it is the source of power. If there is a problem with it, the probability of flight instability is very high.

Another comrade shook his head: "Not likely. Could it be that we have learned the latest findings of the senior consultant and added too many new technologies?"

"That shouldn't be the case, right? We made this missile just to make it simple and cheap, and we didn't add much new technology." This is the comrade in charge of the rocket engine and booster. The structure of this egg is quite special. Such a small missile even uses a second-stage engine. The booster and main engine are separate.

The basis of this missile is to equip a field air defense system with low price. The price was decided at the beginning and it cannot be expensive. Apart from using the second-stage engine according to Gao Zhendong's plan, the comrades kept everything else as simple as possible. Under the guidance of Gao Zhendong's rocket engine design materials, at least in theory, there shouldn't be such a big problem.

The missile's signal engineer frowned and said, "Don't speculate yet. Let's find the wreckage first. But judging from the previous unstable missiles, this possibility is not high."

This is why comrades say that the probability of instability is too high. Many telemetry missiles of this thing have been tested, but more than half of them have become unstable. This is very annoying.

Not to mention half, even 10% is unacceptable.

The wreckage of these unstable missiles seems to have little to do with the rocket engine.

The comrades were waiting for the comrade in charge of the outside search, and everyone was a little anxious.

Not long after, an off-road vehicle came speeding over with the wreckage of a missile on the roof of the jeep.

"Boss, we found it! Take a look." The comrades in charge of the field naturally saw the performance of the telemetry missile in the air. They were also very anxious and found the missile wreckage as soon as possible and sent it over.

The chief model designer was about to rush up when he was stopped by the engine guy: "Boss, let's go first, maybe..."

The warhead of a telemetry missile only has a counterweight, but the propellant in the rocket engine is real.

The chief engineer waved his hand and said, "We've been bouncing on the roof for so long, what are you afraid of? And it's probably not your engine's problem. I want to see the missile's situation at first sight!"

After saying that, he rushed forward with his men, surrounded the missile that had been taken down by the comrades outside, and examined it carefully.

"The engine didn't burn through, but it became unstable before the booster separated. Come, take a look at the condition of the booster." He turned and greeted the person in charge of the engine.

Without his call, the comrades on the engine side had already come over, lay on the ground, shone the flashlight on the back of the booster, and observed it carefully for a long time.

"The booster is intact, the tail nozzle is normal, the throat liner is in normal condition, there is no obvious asymmetric breakage or block shedding, the propellant is completely burned, there is no abnormal residue or broken pieces left... Boss, it seems that it may not be related to the engine."

After careful observation, the person in charge of the rocket engine reported that he could hear a sigh of relief.

The reason for the relief was not because I was cleared of responsibility, but because one of the doubts about the problem had been eliminated. Judging from the engine conditions of so many unstable missiles, it should really have nothing to do with the engine.

This booster is extremely simple. There is nothing special on the booster stage except the booster and tail fin. There are no other cables except the ignition wire.

This booster is only responsible for accelerating the missile to a certain speed. Even the maneuvers in the early stages of missile launch are completed by the wings at the warhead position. The booster is only responsible for making miracles happen with great force.

Therefore, as long as the appearance and structure of the engine are basically normal, then it can be ruled out as a suspicion, and even the suspicion of the booster stage can be ruled out. The main reason is that this thing is really too simple.

“Hmm… That’s strange… There’s no problem with the boost stage, but the instability doesn’t necessarily occur during the boost stage…” The chief engineer touched his nose and pondered.

This is the most troublesome part for the research team.

——There is a clear defect, which is instability during flight.

——But there is an uncertain timing, it may happen in the boost phase, it may happen in the main power phase, or it may even happen in the inertia phase, maybe.

And it has nothing to do with the rocket engine, it seems that the rocket engine is working normally. After all, according to the plan, the rocket engine of this missile is going to be the simplest structure, without even a gas rudder.

Anyone who does scientific research knows that the most troublesome faults are those that are difficult to reproduce stably. For example, this fault occurs at an uncertain time and may even occur in two completely different flight phases, which makes things even more confusing.

"It may be a pneumatic problem, but why would pneumatics cause such a big problem? I have to go back and think about it carefully." said the comrade in charge of pneumatics.

Since this problem can occur throughout the missile's range, it is most likely an aerodynamic or flight control issue.

However, it is impossible for the flight control to inexplicably and frequently issue wrong commands to so many missiles. The comrades in charge of flight control, or all the comrades, have the confidence in this regard. No matter how bad their work is, it will not be so bad.

Therefore, even if there is a problem with the flight control, it is because of some reason that the flight state of the missile changes beyond the control range of the flight control. Here, the problem with the flight control is a result, not a cause. The biggest reason may still be that there is something wrong with the aerodynamics.

The comrades looked at each other in bewilderment. The aerodynamics seemed to be completely fine and functioned normally. Moreover, the Missile Research Institute had developed several types of missiles and had never encountered such a weird problem.

It’s like when a person goes to the doctor and knows the symptom is a fever, but he can’t figure out why he has a fever, no matter how hard he thinks.

"Boss, let's go back to the hospital and hold a Zhuge Liang meeting." The advantage of collectivism was revealed at this moment. All the comrades in the hospital were called together for a collective diagnosis. Three cobblers are better than Zhuge Liang.

"Well, come on, you guys record the situation of this missile, and we'll go back and discuss it with our comrades. Until the problem is found, this telemetry missile can no longer be fired. It's a pure waste of money." These days, it's not uncommon for an entire work to be delayed and stagnant for several years because of a small problem. The Guidance Research Institute has had strong support in recent years, and we haven't encountered this situation for a long time. We didn't expect it to happen again now.

The comrades rushed back to the hospital, but they never expected that the situation was more serious than they had imagined.

The comrade in charge of the ultra-long-range air-to-air missiles frowned like a knot when he heard about their situation at the meeting.

The long-range missile with a range of more than 80 kilometers requested by Gao Zhendong was officially named the ultra-long-range air-to-air missile. Because there were many changes in the missile body, it officially parted ways with the dual-pulse modification of the medium-range air-to-air missile and became two topics - the ultra-long-range air-to-air missile and the long-range air-to-air missile.

"Do you also have this problem?" asked the comrade from the ultra-long-range air-to-air missile department.

"Also? What do you mean also? You are also..." asked the comrade from the short-range radar surface-to-air missile.

Ultra-long-range nodded: "Well, we have similar problems. We have made two types of telemetry missiles in the past few days. One is an extended version of the medium-range air-to-air missile, and the other is an enlarged version of the medium-range air-to-air missile. The results are not very good."

Their idea was to try which approach would work first, at least to get the missile off the ground and determine the structure of the missile's overall plan.

At that time, there were not so many theories and tools for analyzing the various performance of missiles. The simplest way was to make a missile and give it a try. However, the result was not so good.

Same problem as the short-range surface-to-air missile, the missile body becoming unstable in flight, except they have one less fault condition - they don't have a booster, and now they don't have a dual pulse.

But no matter whether it is the main power section or the inertia section, the same problem will occur. It is nothing more than a matter of probability. Their probability is lower than that of low-altitude bombs.

The comrades turned their attention to another group of comrades. Just like the medium-range air-to-air missiles, they also improved on the existing results. In terms of the missile body, there were mainly two improvements.

——The ten-X wing becomes a double-X wing, and the front wing becomes a longer strip.

This change is not very big. At least the basic structure of the missile is still there, so there shouldn't be any big problems.

However, the comrade in charge of this work looked at them with a strange expression.

"Well, it happens occasionally, occasionally, very occasionally..."

If it happens occasionally, it still happens. No matter how accidental it is, it will happen. Existence and non-existence are two different levels of things.

? ? ! !
Comrades were all shocked. What the hell is going on? It has been more than ten years since the founding of the People's Republic of China. No matter what, nothing can become a spirit.

However, the research projects of the entire institute are like a group of people taking the wrong medicine. They all have the same problem. If we have to say, the severity of the disease is different.

This gave the comrades a weird feeling as if they had seen a ghost.

Of course, this is a joke. Comrades know that something must have gone wrong, but the problem has not been found yet.

"That's not right. All the missiles so far have been going smoothly. Why are they all going haywire now? This is weird."

"Yes, if there is a problem, why didn't it happen earlier or later, but at this time? And if we talk about experience, we had less experience before, so why didn't this problem occur?"

This is the most puzzling aspect for the comrades, and it feels a bit like an old revolutionary encountering a new problem.

"The key is that it's like an infectious disease, it's really all over the place." This is the weird part. If there's a problem with a project, it's normal no matter what the problem is, after all, this is new. But it's really weird that multiple projects have the same symptoms on a seemingly unrelated thing.

But comrades also know that if this problem can be solved, it means that a systematic problem in missile design work may be completely solved, and this branch road can be completely paved for future generations.

So the comrades were in high spirits and spoke very actively.

They are racking their brains to find causes, problems and solutions from all directions and possibilities.

But there were not many results, mainly because the situations of these missiles were very different. No matter what reasons they found, it was difficult to form a complete, logically self-consistent closed loop that could meet the situations of all missiles.

The comrades thought about it and discussed it for a long time, but they still couldn't find the real problem, and they couldn't even find anyone to suspect. This was very frustrating, and it was no exaggeration to say that they were at a loss.

The comrades discussed with each other, and then they looked at each other.

"Okay, let's stop thinking about it and just get some help!" There will definitely be a solution if we spend more time, but there's no telling how long that time will take. In order not to waste precious time and money, we have no choice but to go all out.

When it comes to calling for help, everyone knows what it means. Let's go to the 17th Ministry of Machine Building.

Several chief designers of the model looked at each other and said, "Okay, comrades in charge of aerodynamic layout and missile overall design, let's go to the Third Rolling Mill."

Everyone nodded.

That place may not be a quick cure, but it is at least a hope, and it can broaden your thinking and vision, and sometimes you can gain some new technologies. These new technologies may come from that person, or from other brother units led or known by that person.

Since you want to see someone, you have to go to the Defense Work Committee to go through the formalities first.

The Defense Work Committee responded quickly: "Go tomorrow. Comrade Gao Zhendong has something to do today."

It sounded like Advisor Gao was also working on New Year's Day, and the comrades were in awe.

Gao Zhendong: Not really, not at all. I really can’t afford to visit a temple fair.
