Before R&D Zhengxin could complete the calibration and function diagrams, Lu Mingde hurriedly called Li Fanyu.
After being busy for many days, Li Fanyu rarely returned home. Before he could take the chopsticks that An Ning denied, the phone in his pocket vibrated.
When he escaped, he saw that the call was from Lu Mingde. He made an apologetic expression to An Ning and picked up the call: "Hello? Mr. Lu! Is there anything wrong with calling so late?"
"Xiao Li, are the engine performance parameters real?!"
His ears were tickled by Lu Mingde's roar on the other end of the phone. Li Fanyu quickly took the phone away; "Mr. Lu, can this be fake? Didn't the people from the Seventh Division tell you?"
"I said it, but I can't believe it! The maximum power of more than 1,500 kilowatts and the ultimate torque of 7,000 Nm, what kind of thing does this have to be!"
The corners of Li Fanyu's mouth twitched twice...what kind of thing is that, old man!
He was just about to tell Lu Mingde about the specific situation of Longxin B-01 in detail, when he was overtaken by the person on the phone, "Boy, I heard someone from the Seventh Department reported that you just made a test machine. . In this case, you don’t need to say much, just get another one out tomorrow and I’ll have someone pick it up!”
"Huh? So anxious?"
"Don't worry, the only thing missing now is the engine! I originally thought it would take you a few months. But now that it's done, don't delay it. You're also doing the testing over there. Come over and test the two test machines!”
"Uh... that's okay. I'll call the workshop now and ask them to assemble one tonight."
"Okay, okay! That's it, I'll let someone go there overnight!"
Li Fanyu sighed and put down his chopsticks; Got it! I don’t have the luxury of taking a break from my busy schedule!
More than four hours later, Li Fanyu had just assembled two rush-made B-01s at the Power Company, and packed them up and sent them to Tiancheng Airport. There, there is already a transport plane temporarily transferred from the Tiancheng Provincial Military Region waiting to take off!
……
Outside the 850462 Research Institute, in a hangar.
When a group of mechanics installed the B-01 on the mighty-looking tank, the sky was already white with fish belly.
After tightening the last screw, a third-level sergeant stood up and trotted to Lu Mingde. He stood at attention and reported: "Report to the chief! The engine has been loaded and the oil has been filled! Please give instructions!"
Lu Mingde nodded, "Test the car!"
"Yes!"
The sergeant saluted Lu Mingde with a bang, turned around and trotted to the side of the tank, and jumped into the tank's cockpit.
Immediately, with a slight tremor, the roar of the engine resounded throughout the hangar.
After fifteen minutes of warming up as required, the tank moved as the sergeant performed the synthetic operation!
With the performance of the B-01 bunker, the tank started off very quickly. This big guy, equipped with all accessories except ammunition and weighing 65 tons, almost jumped out in a catapult manner!
Seeing this scene, Lu Mingde waved his hand fiercely: "Okay!"
Everyone present knew that this performance was due to the extremely powerful torque! Dragging more than 60 tons of weight, being able to start in such a posture is enough to show the power of the engine!
This is the first time for the noncommissioned officer in the cab to have such a driving experience. Driving this big guy of more than 60 tons, I actually felt a push on my back...
This is **** amazing!
But just when he was about to add fuel again and increase the speed, he heard a muffled sound from the rear of the tank.
Poof!
Quack! ! !
With this series of abnormal sounds, the tank was like a sprinter whose hamstring was suddenly removed. After sliding forward for more than ten meters under the influence of inertia, it stopped.
Seeing this scene, everyone present felt a chill in their hearts.
Something went wrong!
After driving less than fifty meters, something went wrong!
The mechanics present were stunned and ran towards the tank randomly.
Amidst the commotion, some young graduate students from the Academy of Military Science began to whisper;
"The engine is broken?"
"Look at it for sure, the voice just now..."
"I just said that such a high power is unreasonable. There must be something wrong somewhere. Otherwise, it took us half a year to solve the problem, but Zhengxin can do it in less than a month?" ”
"Maybe they are rushing to rush the work, and there are design flaws somewhere."
"Hey, I'm so happy for nothing. I thought the power problem was solved and the fourth generation would be ready for customization soon."
Listening to the soft discussion of the group of young people behind him, Lu Mingde gritted his teeth and turned back to glare at them.
Under his eyes that could shoot out knives, the discussion immediately subsided.
"Let's go! Go and have a look."
Lu Mingde waved and walked over quickly with long strides.
Most of these mechanics in the 85462 Research Institute were drawn from excellent armored divisions. Basically, all of them have more than nine years of military service, and their skills are absolutely useless.
In daily training, a set of quick and accurate techniques have been developed.
A group of people knew clearly, and it took only a few minutes to remove the armored hatch cover above the engine. By the time Lu Mingde separated from the crowd and stepped forward, they had even dismantled the engine.
"What's wrong with the engine?"
Seeing the chief asking the question, the leading non-commissioned officer put down the tools in his hands, stood at attention and replied: "Report! It's not the engine!"
Hmm?
Lu Mingde was stunned.
When he saw the tank lying down, his first thought was that there was something wrong with the power system. And because all parts of the tank except the engine have been tested and passed.
So he preconceived the idea and immediately attributed the cause of the failure to the B-01 engine.
After all, Zhengxin has just manufactured it and has not passed various inspections. If there is a problem with this tank now, the engine is undoubtedly the biggest suspect.
But...it's not an engine?
"What's the problem?"
"Report, transmission!"
Seeing the look of surprise on Lu Mingde's face, the sergeant's eyes flashed, and he said loudly with some hesitation: "Well... report, the power transmission shaft is broken in two!"
Hearing this result, Lu Mingde felt that his brain was not enough for a moment...
Broken drive shaft?
Are you kidding?
This transmission system was jointly developed by the Institute and the military industry unit. It is made of 38 chromium molybdenum aluminum with a density of 7.85g/cm3 and is heat treated! This transmission system has only been used four times, and the usage time is less than five hours. There is absolutely no external factors such as wear and tear.
Why did it break?
At this time, a faint voice sounded behind him.
"Mr. Lu...could it be that the engine torque is too high and the transmission shaft cannot withstand it..."
Having been reminded, Lu Mingde slapped his head hard,
"Remove the drive shaft and conduct cross-section identification immediately to find out the cause!"
……
Three hours later, the test results came out.
Lu Mingde held the cross-section inspection report of the drive shaft and felt quite dumbfounded.
The end of the report clearly stated that there was no abnormality in the strength of the objects to be inspected, no cracks in the main body, and no carbon particles in the defects. Microscopic examination showed that it broke arbitrarily due to external force.
What does this mean?
It means that the torque of B-01 is too high, and the drive shaft is directly torn!
Such power is simply terrifying!
Putting down the report, Lu Mingde smiled and waved to the people around him, "Inform Zhengxin of this situation and ask them to design a transmission that can be matched with B-01..."
