Ten minutes passed in a flash, and the commander-in-chief of the test looked at Jiang Xinwei with an inquiring gaze.

Now Ma Jin's mood can't even tell himself, if he has to decide whether to test or not to test now, he doesn't know what to choose.

Test it, he is worried about failure, worried about the engine explosion caused by blade damage, so many years of hard work in one fell swoop, although it is a bit of an exaggeration to say that it was ruined, after all, the early experience and technical data are there, but the blow to their scientific research process is still huge. But now if he doesn't test the car, he is unwilling, and now his appetite has been hung up by Jiang Xinwei.

"If we succeed, the more experience we gain and the more confidence we have, the sooner our engines will be used and our factories will be able to reap economic benefits at least a year earlier." ”

Guichang Aviation Machinery Factory is now basically an enterprise that only consumes money and does not make money, Jiang Xinwei has invested more than 4 billion yuan in this factory, not to mention that it is difficult for a private boss to have such a big courage, even a country, may not have the courage to make the factory so frightened and tossed.

The benefits are produced early, and everyone is at ease as soon as possible, so as not to worry about others looking at the people on their side with strange eyes when they go out. Sometimes in a dream at night, Ma Jin and Wang Xiaoli both dreamed that Jiang Xinwei called them over and scolded them, and then informed them to stop funding and dissolve the Guichang Aviation Machinery Factory.

They had been woken up a few times by this nightmare.

Jiang Xinwei didn't embarrass him, seeing his eyes looking at him, he said firmly: "Let's start the test car, it's okay, isn't it possible to damage an engine? Not this time, we'll come back next time!"

Hearing Jiang Xinwei's words and seeing Jiang Xinwei nodded, Ma Jin breathed a sigh of relief, as if he had been waiting for him to say this for a long time.

As the commander-in-chief of the test run, he shouted: "Everyone, pay attention! Prepare in one minute! Keep the rated power of the engine unchanged! The sandblasting test has entered the one-minute countdown!"

The people in the test workshop closed their mouths, and many people even held their breath, looking at the running engine outside the bulletproof glass with concern and excitement.

Ma Jin didn't look at anything, he closed his eyes, calculated the time carefully, estimated that it was almost over, then opened his eyes suddenly, and shouted loudly: "Enter the ten-second countdown, 10!9!8!7!6...... , 2!1! Start blasting!"

The test driver, who had been ready for the moment, pressed the sandblast button hard.

Immediately, the special sandblasting equipment on the test bench spewed out puffs of sand from the desert area.

Everyone's eyes widened, and everyone's hearts were in their throats.

Some of the sand was sucked into the engine and disappeared, while others were sprayed out, creating a dust curtain that obscured a small part of the engine.

As more and more sand was sprayed, and a lot of sand was sprayed out of the exhaust nozzle of the engine, the entire vicinity of the engine test bench suddenly became dusty, and the huge engine on the test bench began to become blurred.

Several people, including representatives of relevant departments, were a little worried.

The representative eagerly asked, "How's that?"

Despite his high position, no one paid any attention to him, no one answered him at all, and an expert staring at the on-screen data glared at him in disgust.

But the nervous representative didn't care, but leaned his head closer, stared at the data on the computer screen, saw that there was no red color on it, and kept asking: "Is it normal now, right? Now it is normal? There is no danger......

Although the test run was planned to take only three minutes, people still felt that it was too long, and some people scolded those who made the test process for being boring: "These people are bastards! You don't want to think about who would drive a helicopter into the desert and stay in the dust for three minutes? At most, it will run away in a few seconds." If you stay for a long time, you will commit suicide, how can a pilot be so stupid?"

Time passes by one second, and three minutes is equivalent to one hundred and eighty seconds.

People's hearts beat so violently that they were all more than 200 beats, and except for those who had to stare at the screen, other experts and technicians were staring at the engine that had been covered in sand and dust.

Now you can only hear the sound of the engine, you can't see the engine at all, you can only see its outline.

Time passed second by second, and finally, one hundred and eighty seconds arrived!

Ma Jin shouted tremblingly, "Stop blasting sand...... and we succeeded!"

In the end, he couldn't help but scream.

But to his surprise, no one else cheered with him, and everyone still stared at the engine in the dust.

As the sandblasting stopped, under the exhaust of the powerful exhaust fan in the test workshop, the sand and dust around the test bench quickly dispersed, and the engine on the test bench slowly revealed its true face, and it didn't take long for everyone to see it clearly.

However, everyone did not move, and they all continued to stare, as if watching their children on the other side of the river, struggling in the dangerous torrent, trying to get rid of the impact of the flood and crawl slowly towards the shore.

Jiang Xinwei's mood was excited and happy, he didn't bother the others, just patted Ma Jin on the shoulder, and then looked at the monitoring data on the monitoring computer like that representative.

Ma Jin also watched for a few seconds, but then ordered loudly: "The monitors report their respective monitoring conditions!"

Several monitors were stunned, because there was no such process in the test process, and it was completely added by Ma Jin. But they soon came to their senses, and a female monitor looked at her computer screen and shouted, "The engine burns fuel normally!"

Then, a male monitor stared at his computer screen and shouted, "The engine is vibrating normally!"

One by one, the monitors began to shout, their voices getting louder and louder, and their emotions became more and more excited and proud:

"The engine output is normal!"

"The engine temperature rise is normal!"

"Engine noise is normal!"

……

These shouts finally woke up the experts and technicians, and they returned to normal one by one, and they all looked at the loud monitors with joy and gratitude, as if they were the heroes of the development of this engine.

"We succeeded!"

"Our helicopter has a heart of its own!"

"We are heroes!"

……

Ma Jin ordered loudly: "The test is over! Stop the test! Inspect the engine completely!"

The test driver was reluctant to press the stop button, and it was not until Ma Jin's eyes swept over that he reluctantly pressed his thumb. Soon, the engine stalled, and the deafening test sound in the monitoring room gradually stopped.

Everyone look at me, I look at you, and then shouted in unison: "Success——!"
