Zhao Wangba looked at the wreckage of the plane in front of him, he was dreaming of his dream of being promoted!
Yan Mingcheng asked several soldiers to disassemble the engine on the helicopter with tools, and then carried it to an armored vehicle. This one-ton engine was sent to the underground laboratory of Jianggong University by this armored vehicle.
After that, Yan Mingcheng and Zhao Zhongyao Zuo Junqiang flew back to Jianggong University in the Xiaoshanying helicopter.
In the next few days, Zhao Zhongyao disassembled and studied the engine of this helicopter. Finally he found the real cause of the helicopter crash.
Zhao Zhongyao found that among the eight cylinders of this engine, there was a small crack on the edge of one cylinder. It's just very small, if you don't look carefully, you can't see it at all.
However, it is this small crack that allows some air to suddenly enter the cylinder when it is working, causing the fuel to not be fully combusted, so the engine will naturally stop.
"Ah, so that's the case! I searched for the reason for a long time, but I couldn't find it out!" Zhao Zhongyao looked happily at the cylinder with a crack in front of him.
Originally, he thought he had found the real reason for the engine stalling, but after calculating some of the data he measured, he learned that although this small crack had a great impact on the engine, it could not cause the engine to stall suddenly.
The cause of the sudden flameout of this helicopter must be another problem. Zhao Zhongyao fell into deep thought again.
"Hey, could it be a problem with the fuel!" Zhao Zhongyao thought, in addition to the problem of the engine itself, the reason that could cause the engine to stall may also be the problem of fuel.
"Well! That must be the case. I haven't checked the fuel in the engine yet! See if there is something wrong with the fuel."
Thinking of this, Zhao Zhongyao took a little fuel sample from the engine cylinder, and put it under a special microscope for observation.
He discovered that the fuel composition in this helicopter was actually the same as ordinary gasoline. Doesn't meet aviation fuel standards at all.
Because the aircraft flies in the atmosphere, all power is completely provided by the engine. Once the engine fails, the consequences are unimaginable.
Therefore, aviation fuel is much higher than ordinary automobile fuel standards. Aviation fuel is of course gasoline, but the purity of this gasoline is much higher than that of ordinary gasoline. In particular, the content of aromatic hydrocarbons is much lower than that of regular gasoline.
The standard of aviation fuel stipulates that the content of aromatic hydrocarbons shall not exceed 20%. Now, the content of samples collected by Zhao Zhongyao in the Xiaoshanying helicopter has reached 40%, which is far higher than the standard of aviation fuel.
"How could this be? Did this helicopter use ordinary gasoline?" After Zhao Zhongyao tested the samples, he was sure that the engine of the wrecked Little Eagle used ordinary gasoline, not aviation gasoline .
"Well! I see. It turns out that during the flight of this helicopter, a small crack suddenly appeared in the cylinder. The engine uses ordinary gasoline, which can easily cause the engine to stall and cannot be re-ignited. And The other helicopters may also use ordinary gasoline, but the engines of these helicopters have not failed, so naturally there is no accident for the time being."
After several days of detection and analysis by Zhao Zhongyao, he already knew the real cause of Xiao Shanying's crash.
After finding the real cause of the engine crash, Zhao Zhongyao wrote an inspection report and handed it to Zuo Junqiang.
After Zuo Junqiang looked at it, he said to Zhao Zhongyao: "Okay, it seems that it is still a problem with the engine!"
Zhao Zhongyao reminded again: "Principal Zuo, fuel is also one of the reasons!"
"Then who would change aviation fuel into ordinary gasoline fuel!" Zuo Junqiang was very puzzled.
"Principal Zuo, we are only helping Captain Yan and the others to find out the cause of the plane crash. As for other matters, let them solve it themselves! I suspect that someone tampered with the fuel of the helicopter."
Zhao Zhongyao thought that military aircraft fuel is a very important military material, and it cannot be sloppy. Such important military supplies will be replaced by ordinary gasoline, which shows that someone has profited from it.
"What, Zhongyao, do you think there will be some conspiracy behind this plane crash!" Zuo Junqiang was startled when he heard Zhao Zhongyao's words.
"Of course, the price of aviation fuel is several times that of ordinary gasoline. If someone replaces hundreds of tons of aviation fuel with ordinary gasoline, he can immediately make millions of profits from it!"
Zhao Zhongyao is a person about analysis and reasoning. From the fact that aviation fuel was changed to ordinary gasoline, he speculated that the crash of Xiao Shanying was probably done deliberately. It's just that he didn't dare to say so absolutely. It's just that someone embezzled money from it.
"Zhongyao, according to what you said, the matter seems to be very serious. I will send this material to Mr. Chen and let him solve it by himself!"
"Yes! The situation is very serious! Let's hurry up and give the materials to Mr. Chen!" Of course Zhao Zhongyao nodded in agreement.
Zuo Junqiang immediately sent someone to send this important material to the division headquarters, Master Chen.
After Chen Daotian read Zhao Zhongyao's test report, he was taken aback.
"His grandma's, aviation fuel, how did it turn into ordinary gasoline? Could it be—————" Mr. Chen didn't dare to think about it anymore.
"It's over, it's over, I have to hurry up and get this copy
The material was returned to the superior. Otherwise, let the leader find out, and my crime will be serious. "
After reading Zhao Zhongyao's inspection report, Mr. Chen knew that the matter was serious, so he quickly handed over the helicopter crash and Zhao Zhongyao's inspection report together.
After the superior leader knew about it, he immediately sent a working group to investigate, and quickly found out the truth of the matter.
It turns out that Mr. Chen has a deputy division commander named Liu Ming, who has always had a bad style. Often accept gifts from some grassroots company leaders. For this, he was punished several times. People like him should have changed jobs a long time ago.
But because he has some relatives with a certain leader above, in this way, although he has received several punishments, he still serves as the deputy commander of the armored division in Jianghai City.
Liu Ming is the deputy division commander, and his main job is to be in charge of the logistics supplies of the troops. This time, he was also responsible for transporting the aviation fuel for the new Xiaoshanying helicopter from the logistics department.
These aviation fuels are expensive, hundreds of tons of aviation fuel are worth tens of millions.
Seeing the tens of millions of wealth, Liu Ming was really tempted. But he also knows that these aviation fuels are not trivial, so he should not pay attention to these military supplies.
