Rebirth of the 1980s: The Military Industry Empire

"No, it's too dangerous!" Zhang Baozhong raised his head from beside the engine and looked at Qin Yang: "What if the tank bumps and throws someone off?"

The blind spots around the tank are too large. It's dangerous to even pass by the tank, let alone tie yourself to it!

"That's right, Chief Engineer Qin has participated in many research and development projects and is the backbone of our military industry. We absolutely can't let anything happen to him. Even if he doesn't get thrown off, bumps and bruises aren't good. Let's tie me up there instead!" Another voice spoke.

Guo Liming! This man had a tortuous experience. He once opposed the 150HB diesel engine project and even scolded the factory director. But now, he is a staunch supporter of the 150HB diesel engine and a key technical personnel for this engine. Therefore, he wants to go up there himself!

"You can't do it," Qin Yang shook his head. "You don't have experience in this area."

"Chief Engineer Qin, you don't have experience either."

"You dare to say I don't have experience? Since I proposed this solution, I must have tried it before. Stop making excuses. I haven't contributed to our project in the past few months. I happened to be here this time to find the cause of the malfunction. I'd like to see who dares to steal my credit!"

Zhang Baozhong looked at Senior Engineer Zhu, wanting him to dissuade Qin Yang, but Senior Engineer Zhu didn't speak, only looked at Qin Yang with a complicated gaze.

With technology, ideas, and drive, Chief Engineer Qin is a natural talent for the military industry. It's a pity there's only one!

If there were a few more, Chief Engineer Qin wouldn't have to run back and forth.

Senior Engineer Zhu looked at Qin Yang with admiration. By the time he recovered from these thoughts, Qin Yang had already tied himself to the tank, holding a flashlight in his right hand and a mirror in his left, urging, "Okay, start the engine and drive it out to see!"

"Wait for me!" Guo Liming wanted to climb onto the side of the turret and observe with him, but Qin Yang waved his hand: "What are you doing here? Trying to steal my credit? Let's go now!"

Guo Liming was helpless.

The tanker went to the front driver's cabin, started the engine. The high-pressure oil pump made a strong and powerful sound, the exhaust pipe emitted plumes of black smoke, and then the entire engine began to tremble rhythmically.

The engine has been successfully started!

Engage gear, reverse!

Generally speaking, tanks are reversed into the garage for convenient driving out. However, this tank came in a hurry and drove straight in, so now it has to back out.

Until now, Qin Yang hadn't glanced at the front of the tank, not knowing whether the front armor was designed as a V-shape like the T-72. Now, he only focused on the engine at the rear.

His right hand held the flashlight, shining it on various parts of the engine compartment. Some places were too small to fit the flashlight, so he had to use his left hand to insert the mirror and reflect the light. In this way, he kept searching.

The tank slowly exited the warehouse, then turned and moved forward.

Qin Yang observed carefully. There was no oil leak. The engine was intact.

"Accelerate, accelerate!" Qin Yang shouted loudly.

Many malfunctions occur at high speed. The tanker in front was afraid of throwing Qin Yang off, so he didn't dare to speed up, and the malfunction wouldn't reappear.

Whoosh! The gearbox gears rang, the gear was increased, Qin Yang's eyes continued to stare at the engine compartment, but there was still no oil leak!

"Turn, brake, then accelerate again, do it a few more times!"

The tanker gritted his teeth and pulled the steering lever sharply. The tank suddenly made a sharp turn, and Qin Yang's body slammed against the steel plate with a thud. It was a little painful, but he just frowned and continued to observe the engine compartment.

What was this!

Qin Yang learned this trick from his previous life. Back then, the technicians who worked on the 99 tank were quite desperate. When there was an oil leak during the cold region test, they tied their bodies to the tank. To be more flexible, they didn't wear military coats and let the tank drive at high speed in the cold wind, finally finding the source of the malfunction.

Afraid of hardship, afraid of fatigue, afraid of injury, you can't engage in the military industry!

Suddenly, Qin Yang thought of something. The flashlight shifted direction and shone towards the planetary gearbox. When the tank turned again, a thin stream of hydraulic oil sprayed out from inside with a whoosh, directly onto the engine block.

So that was it!

Everyone had been looking for the oil leak on the engine, after all, this was a 1200-horsepower engine, the first time it was manufactured domestically. Whether it was materials or processing technology, it was difficult to meet Western standards, so there must be defects.

Previous oil leaks were also on the engine. Everyone had a habitual way of thinking, looking for the oil leak on the engine, but they didn't think that the oil leak came from the vent of the gearbox. It would only spray onto the engine when turning, making people think it was the engine leaking oil!

The gearbox is not a sealed structure. After all, the gear oil inside expands when heated. If there is no vent hole, the oil seal of the bearing will leak quickly.

This vent hole generally does not leak oil, unless there are special circumstances, such as too much oil added, or unreasonable design, etc.

So that was it! Everyone suddenly understood.

"Our planetary gearbox is a copy of the T-72, but because it has to transmit more power, we made improvements," Senior Engineer Zhu said. "But after the improvement, we were afraid of poor lubrication, so we added a lot of gear oil. It seems that we have to draw some out and determine the optimal oil filling amount through actual testing and theoretical analysis."

Originally, they planned to use hydraulic transmission, but Qin Yang rejected it, saying that they couldn't handle it with the current technology. They should honestly use ordinary gearboxes and copy the T-72.

However, the T-72 engine only has 780 horsepower, while ours has 1200 horsepower, so it certainly cannot be directly copied and must be enlarged to withstand enough power.

After enlargement, how much oil to add to the gearbox needs to be determined by combining theory and practice.

This kind of malfunction cannot be tested on the test bench, only when it is actually running can it be known.

"Chief Engineer Qin, you have solved another big problem for us."

"Senior Engineer Zhu, the way you say that makes it sound like I'm an outsider," Qin Yang said, moving an arm, immediately wincing. His elbow had been hit repeatedly several times, it hurt.
