Chapter 736 Suffer!
Even at a high speed of Mach 0.85, it takes nearly 300 seconds for the missile to fly the entire distance. The maximum designed range of this thing is 80 kilometers!
This is something that many people will subconsciously forget. The missile flies so fast, just tens of kilometers away, and it is sprinkled with water~~~~~~
In fact, it takes a long time to fly with a range of 80 kilometers, at least the comrades who participated in the test today felt that it took a long time.
This is the longest they have waited. Even though the missile has accelerated to Mach 0.9, its 80-kilometer range is still the longest except for ballistic missiles.
This is a new feeling for the comrades participating in the experiment. The farther the range, the longer the anxiety caused by waiting for the results.
At this time, the real-time data transmission system has been offline, and missile data cannot be obtained in an intuitive way.
"It would be great if there were radar in the sky to help monitor", everyone was thinking in their hearts.
Calculating the time, the missile should have flown to the target area, where a helicopter is on an observation mission in the air.
"Coming, coming! Report! The target was observed and the flight is normal."
Although the missile did not fly fast enough, the speed of electromagnetic waves was faster. As soon as the observation machine saw the telemetry bomb, their voices rang out at the test center.
"Okay!" The scene was filled with joy. 80 kilometers was something I had never dared to think about before.
Just as everyone was immersed in joy, a somewhat regretful voice came from the radio station.
"Broken! The bomb dropped! The bomb dropped! The missile has not reached the final target area and fell into the sea."
On the observation plane at this time, the comrade in charge of the observation watched with distress as the missile in flight suddenly increased in height, took off, and then plunged into the sea.
The dye loaded on the telemetry bomb was quickly released into the sea water, and a fluorescent green color quickly spread out on the sea surface, which looked very dazzling in the somewhat muddy yellow sea water.
The report from the front made the comrades in the experimental center feel like they had been hit in the head, and they fell silent instantly.
Everyone looked at each other, failed? Dropped bullet?
Everyone looked at Mr. Li, but no one said anything.
Seeing everyone looking at him, Mr. Li remembered his work and responsibilities, forced a smile and comforted his comrades: "It's okay, this is the first telemetry bomb. At least, there is no big problem with the range of about 80 kilometers. It was tested. For several major targets, at least the range has been verified.”
There are many possibilities for the bullet to drop, and one possibility is that the power is insufficient to reach the full designed range.
However, judging from the movements of the missile before the missile was dropped from the forward observation machine, it does not seem to be caused by insufficient power, otherwise the final height increase would be unlikely to be achieved.
This performance looks more like a problem with the guidance or flight control system.
So Mr. Li said that the range has been verified, which is not a big problem.
Seeing that everyone was in a better mood, Mr. Li encouraged again: "It's okay. Listen to the reports from the comrades at the front. At least the splash mark dyeing device is working normally. The top priority is to get the bullet back quickly. There is data on it. Let's take care of it." Analysis analysis.”
These words reminded everyone that now is not the time to be depressed, now is the time to quickly retrieve the telemetry bombs.
In fact, they didn't need to be busy. The salvage team originally waiting in the target splashdown area had already started the salvage ship after receiving the notification from the observation machine. Under the guidance of the observation machine, it headed towards the bomb drop point.
Fortunately, the distance was not too far, only a few kilometers. In everyone's anxious, frustrated, disappointed, and distressed mood, the sound of the observation machine finally came from the radio.
"The salvage ship has arrived at the bomb drop point and is salvaging it."
Everyone was slightly relieved. Success was either absolute or not. Mr. Li's comfort was just comfort to everyone. This telemetry bomb still failed.
The biggest hope now is that the faulty bomb can be successfully salvaged, and the cause of the failure can be analyzed based on the data on the bomb.
It's already lunch time, and it's not often that there are so many people here. Today's food guarantee is self-heating food, which is a good thing that you can't usually eat.
But no one is willing to tear open the packaging bag and cannot eat it.
At this time, the role of leadership must come into play.
Mr. Li was the first to walk over, pick up a package of self-heating food, and tear open the package.
"Comrades, eat first! If you don't eat, how will you have the strength to do your job well? Eat! Eat everything!"
The comrades became listless and went to eat in twos and threes.
While everyone was eating in silence, a report from the salvage ship ahead came over the radio.
"The salvage of telemetry bombs is completed and we are returning!"
Fortunately, the Bohai Sea is really thin. As long as the splash zone is marked, even if it is disconnected from the inflatable buoy and sinks completely, it can still be found and fished out. Even the most ordinary divers can dive into water depths of tens of meters and tens of meters. Have to go down, let alone a Navy diver.
Now everyone has some motivation and eat quickly!
At a distance of seventy or eighty kilometers, although the salvage ship can only travel at a speed of more than ten knots, it can get back in two or three hours.
You have to eat quickly. Only when you are full can you have the strength to work.
Suddenly, the sound of eating became louder.
A few hours later, a ship docked at the small dock of the experimental center, and a group of people gathered around it.
Fortunately, the loaded data was not damaged and the reading went very smoothly.
Comrades working on solid anti-ship missiles began to divide their work in this test center, each reading and analyzing the data of the subsystems they were responsible for. "The control actuation system works normally, and the instructions and feedback received are consistent."
"The missile ran out of fuel, but the flight status was stable before the missile was dropped. The speed was not abnormal and the kinetic energy was sufficient. It was not caused by insufficient power."
"The altimeter data refresh rate is consistent with the design."
"Radar! There's something wrong with the radar!"
"Radar?"
"Yes, radar! Ordinarily, at this distance, the radar should have locked on the target, but before the bomb was dropped, the radar unlocked."
"Unlocked before the bomb dropped? That means it was locked before that?"
"Yes, it was locked before that, but it was unlocked before the bomb was dropped, and the radar system sent out a wrong signal."
"What is the reason for this? The locked radar actually unlocks? This is not very common."
"It is rare for Zhengxian No. 1 to be unlocked. It is said that the technology of the two is the same."
"Is the radar of Zhengxian No. 1 bigger? After all, the bomb is very thin."
Compared with the Zhanxian No. 1, the caliber of the solid anti-ship missile is much smaller, and the radar performance is indeed not as good as the Zhanxian No. 1 in terms of basic conditions.
"That doesn't make sense. It was locked before it was unlocked. The closer the distance, the more it unlocked?"
The closer the distance, the better the signal strength and the higher the signal-to-noise ratio, which is almost a no-brainer.
Just when everyone was talking about it and couldn't agree on what to do, some comrades suddenly discovered another problem.
"No, no, there seems to be something wrong with the altimeter."
"I've seen it. The altimeter output is normal. What's the problem?"
"I can't tell, but I just feel that there is something wrong with the altimeter. It seems that the data refresh rate cannot keep up with the control requirements."
"It's impossible. This altimeter was very normal on Zhanxian-1, and it seems that the data output was still normal until the end."
Qi Gong was in charge of the guidance system. He and Su Weihua also discussed it for a long time, but did not get a clear result.
He looked up at Mr. Li, who looked at him, and then they both turned to look at Su Weihua and nodded.
Forget it, time is urgent, cheat! Shake people!
"Xiao Su, collect all the data read by each subsystem, let's go to the capital!"
When Su Weihua heard this, he decided to go find his old classmate.
"Go there?"
"Well, yes, go there! There is a lot of research on radar, automatic control, power, and guidance there. Let's not waste time and see if we can find some direction there."
The "there" they were talking about was undoubtedly the Third Rolling Mill of the Seventeenth Machinery Department. The reason why they spoke so vaguely was because of the need for confidentiality. Secondly, this matter should be brought to this unit. In the eyes of ordinary comrades, It sounds unreliable, so I won’t say it anymore.
Anyway, they kept talking like this for a long time, and ordinary comrades would never imagine that their goal was to find the same person.
"Radar, automatic control, power, and guidance are all very well researched." This must be a large design institute.
For Mr. Li, it is not necessarily expected that Gao Zhendong can completely solve the problem, but even if he can find some clues or directions, that would be good.
Fortunately, the experimental site was right on the Bohai Sea, not too far from the capital. In the afternoon of the next day, they showed up in Gao Zhendong's office.
"Professor Gao, we are here to ask for help." Nowadays, subordinate units of the National Defense Working Committee usually refer to Gao Zhendong's teaching position at Beijing University of Technology.
As soon as Mr. Li sat down, he spoke.
Gao Zhendong put the water on the coffee table and said with a smile: "I don't dare to ask for help, but there is something we can still discuss carefully. Is it because of the problem of solid anti-ship missiles?"
This is what they are busy working on now. There is no news of success yet. This is probably why they came.
"Yes, yes, that's the situation. Yesterday, we fired the first telemetry round of a solid anti-ship missile..."
Mr. Li explained the matter in detail, and Qi Gong stood by to make supplements.
Mr. Li is the chief model engineer, and the problem most likely lies in the part that Qi Gong is responsible for, and Su Weihua is the link, so the three of them are here this time.
After hearing this, Gao Zhendong had some vague guesses in his mind, but he couldn't be sure until he saw the data.
"Have you brought the experimental data?" he asked.
"Bring it, bring it, take a look." After Mr. Li said that, Su Weihua started to dig out his wallet. The data had been printed out. It didn't look like a lot. The main reason was that the capacity of the missile's magnetic core memory was very limited. The types, entries, and refresh rates cannot be too high, and we can only focus on the most important ones.
