"His ability, we all know, is that the young man is thick-skinned. After Zhang Lao finished speaking, he looked at Su Lao and asked seriously: "How is it, are you sure?" ”

"No problem, the success rate is over 80%. ”

"That's good, that's good, if it happens, you're a great hero. Zhang Lao said happily, and after speaking, he turned to Liu Chi and said, "Especially you Xiao Liu." ”

"Su Lao is the hero, I'm just a brute force. ”

"Okay, there's no outsider here, so don't be modest. Su Lao interrupted Liu Chi's words and asked Su Lao, "By the way... When can I start?"

"......" Liu Chi also moved his gaze to Su Lao.

"Ready to start. Su Lao looked at the people who were still drilling up and down, scurrying in and out, and explained: "They want to check a few more times to ensure that the success rate is greater." ”

"Then I'll get ready. ”

"Xiao Liu, Xiao Ye, let's go to the viewing platform to watch. Elder Zhang beckoned to Liu Chi and Ye Yuxin.

"Let's go, girl. ”

"Hmm..." Ye Yuxin took Liu Chi's hand and followed behind Zhang Lao.

“......”

After ten minutes of waiting.

With Su Lao's order.

The 99 tank, which had already begun to warm up, began to move slowly.

"It's moving, it's moving......" Ye Yuxin changed from nervousness to excitement: "Liu Chi saw it, moved, moved." ”

The tank slowly turned in place for a few minutes, confirming that the engine was functioning normally.

"It was reported that the motor machine was normal, the data was normal, and there were no anomalies. ”

"The first test, the speed limit test. Su Lao took the walkie-talkie, and after receiving the report that everything was normal, he said, "Let's start." ”

The tank, which was supposed to be moving slowly, received the order, and it "soared" like a loaded shell.

On the test road, a large sandstorm broke out in an instant with the 'FU'.

"It's so fast..."Liu Chi's first reaction.

The scene resembles a jet flying by, with a long trail of smoke whistling from under the viewing platform.

"Lean ......"

Looking at the speeding tank, Liu Chi couldn't help but burst into a foul mouth.

It's so cool!

It's like being beaten with chicken blood, and the whole person is excited.

Report speed.

"......" Ye Yuxin stared at the rapidly departing tank, holding Liu Chi's hand tightly with both hands, and her little face was also flushed.

Su Lao was not excited, and asked with a serious face: "Report the speed!"

"REPORT: 48KM/H. ”

"Push the speed to the top. ”

"Yes!"

As the sound fell, the tank was fitted with a vector engine.

Burst......

Leave a puff of sand and dust for Liu Chi and the others, and in less than half a minute, only a small black dot was seen.

"REPORTING SPEED, IT'S NOW 85 KM/H. ”

"Is it the limit?" asked Su Lao anxiously.

"THE LIMIT IS 88KM/H......"

“......”

Ten minutes later, the tank drove back at a speed of about 60KM/H.

"It's a 360-degree turn ahead, pay attention to the speed and don't roll over. Su Lao looked at the tank that rushed under the viewing platform and reminded.

Liu Chi leaned on the edge of the viewing platform, his neck stretched out, staring at the faster and faster tank approaching the 360-degree sharp turn.

‘fu’

"Ahhh!!h

"Lean, it's going to overturn, it's going to overturn......" LIU CHI LOOKED AT THE TANK AT LEAST PAST 60KM/H SPEED, AND MOVED SIDEWAYS DIRECTLY.

It's like a rough blast impact.

In the middle of the 360-degree arc bend, the tank slid at least 10 meters due to inertia.

The scratches on the ground are shocking!

"......" Liu Chi's eyes widened: "There is still a drifting ???"

It's broken...

"Report the speed !!" Su Lao's hand trembled a little.

"REPORT: SPEED 63KM/H. ”

"The 100 meters ahead is a pool of water, sprinting at full speed. ”

"Yes!"

Less than ten seconds!

A pool of water nearly half a meter deep 'boomed' like a bomb was dropped, and it flew out of the sky.

The tank, like an arrow, pierced through.

Before Liu Chi could react, the tank had already crossed the 30-meter-long pool, and after the entire pool had passed the tank, the water was directly reduced by one-third.

"After 50 meters is the step test, pay attention to ......"

"Boom..."As soon as Su's old words fell, the tank was directly thrown up one meter high.

"..."Liu Chi watched the 50-ton big guy fly, and he could stuff his fist into his mouth for a while.

！！！

Then there was another loud 'boom'.

Dusty sky.

'Poof......'

The tank that fell to the ground did not stop, and the speed did not decrease and went directly to the dust.

"Report, there is a problem with the engine. ”

"What's the problem?" said Su Lao hurriedly.

"The engine has stopped working. ”

"What?"

"Confirmed, the engine has stopped working. ”

"Find a way to stop right away and stay safe. Su Lao roared.

“......”

"Is there something wrong?" asked Elder Zhang, looking at the anxious Elder Su.

"The engine stopped working, so I'll go over and take a look. After Su Lao finished speaking, he didn't wait for Zhang Lao's reaction, and hurriedly ran down the viewing platform.

"Let's take a look. Liu Chi let go of Ye Yuxin's hand and ran down with Zhang Lao heroically.

Two hours later.

"Mr. Zhang, Mr. Su, Mr. Liu, the problem has been found out. ”

"What's the problem?" Su Lao hurriedly put his brain in.

"There was a problem with the suspension system, and one of the suspension was broken, which should have been torn off directly when the trapezoid was tested just now. ”

"The third heating device on the left was scrapped and the oxygen supply system was destroyed, thus terminating the engine. "Lee will get out of the tank.

"I'll see. Su Lao pushed Li Hui away and personally stepped forward to inspect it.

"It doesn't make sense, when we use the original engine, don't say one meter, even if it's three meters, it won't break. Someone on the side questioned it.

"But is it really broken now?"

"Uh......"

"Could there be a problem with this suspension?"

"It's impossible, how can something used in equipment not take into account the quality problem. ”

"Take it out and look at it first, and then take it back and test it. ”

"Yes, yes, take it out first. ”

Su Lao looked at the section of the structure that hung and fell for a long time, and when he was wondering why it was broken, he was also facing the same huge doubt.

Cutting corners on products?

Impossible.

What's the problem?

"Old Su, take things out and take a look first. ”

"Okay, let's take a look. Su Lao looked at the old man for a long time, and he couldn't find a problem.

“......”

After a lot of work, the suspension system of the engine was finally removed.

While everyone was discussing, Liu Chi picked up a broken light steel structure and observed it carefully.

......

"Maybe ......" Liu Chi said thoughtfully: "Maybe I know the cause of this accident." ”

In Liu Chi's hand, he held a round piece of synthetic light steel, and he could clearly see that this round light steel was surrounded by a layer of reddish-brown coarse particles from the fracture.

This is the most intuitive manifestation of obvious metal fatigue, its internal structure has been destroyed by external forces, and its strength has been seriously reduced.

"The cause of metal fatigue should be the blast force breaking at high temperatures. Liu Chi said.

"High temperature?" said Su Lao a little puzzled.

"Old Su, don't forget, the heating device is as high as 550 degrees, and this suspension happens to rely on the heating device. ”
