"Let's get started!" Zhang Yi said to Xiang Juncai after the door of the control room closed.

"Start test driving!" After listening to Zhang Yi's words, Xiang Juncai ordered loudly.

Following Xiang Juncai's order, the controller pressed the engine start button. The engine on the test bench also pressed the button. The engine began to make a knocking sound, and the speed also began to gradually increase.

Soon the engine reached a low power output state, and at the same time various monitoring personnel began to report engine data.

"Engine power output is normal."

"Combustion chamber temperature is normal."

""

In fact, there is no need for them to report it. Just listen to the regular knocking sound of the engine at this time, and you can know clearly. What's more, there is a virtual model of the engine in the monitoring room. If there is a problem, you can immediately check it from above.

Learn about the condition of this engine.

After turning on the low power output state and finding no problems, the engine immediately entered the cruising working state. During the test run, the entire test run platform will also simulate various harsh weather conditions, such as high temperature, high humidity, and low temperature.

Hypoxia, etc.

As the test subjects progressed one by one, the working condition of the engine was as good as that of the spacecraft, which made everyone in the entire monitoring room feel very relaxed. Finally, after cruising, the engine entered the highest power state.

"The engine is working normally!" With the completion of the final high-power test, Zhang Yi, Xiang Juncai and others all smiled, which proved that the problems exposed in the first test of this engine have been effectively solved.

Zhang Yi and Xiang Juncai looked at each other, and both of them saw joy in each other's eyes. The test run at the maximum power working state was successful. If the test run steps of other aerospace engines are followed, the test run of the engine should also be coming to an end.

.

But in fact, for Zhang Yi's engine, this test run is actually far from over.

I saw Xiang Juncai make a gesture, and then said loudly: "The engine is ready to switch to working mode and enter the anaerobic environment working mode."

"What! Anaerobic working state." When Xiang Juncai issued this order, General Kong and the two experts who came with him couldn't help but exclaimed at the same time.

You must know that this is an anaerobic working state! In other words, this engine has the ability to work in outer space.

"Yes! General Kong, this engine was designed to work in an oxygen-free environment. However, according to the current technological situation of human civilization, although the engine we designed can allow this engine to operate in an oxygen-free environment,

working status, but the consumption of electricity and water is relatively large, and it is simply unable to support the aircraft working in an oxygen-free environment for a long time." Zhang Yi said.

"This is already very impressive!" General Kong said.

While talking, I saw that the air inlet in front of the engine on the virtual display screen began to be closed, and the color of the engine's tail flame also changed. Originally, the engine's tail flame was blue, and could be clearly seen.

As you can see, when it enters the anaerobic environment, the tail flame of this engine slowly begins to fade, and the length of the tail flame also begins to shorten.

"Report the engine working status!" Xiang Juncai said shortly after the engine entered anaerobic working status.

"The temperature of the engine combustion chamber is rising. The current temperature in the center of the combustion chamber is 650 degrees and the temperature in the periphery of the combustion chamber is 4510 degrees."

"The temperature of the inner wall of the combustion chamber is 2802 degrees, and a restraint device is required to increase the restraint energy."

""

Since the engine's air inlet has been closed after the engine enters the anaerobic working state, all the engine's working energy at this time comes from the ionized hydrogen and oxygen, so in such an environment, the fuel supply will increase

, this causes the temperature inside the combustion chamber to rise sharply, and naturally the temperature of the inner wall of the combustion chamber also begins to rise sharply.

Entering this working state is a huge test for this engine. After all, during the first test run, even in the maximum power operating state, the engine had problems, and now the temperature of the entire engine is at least higher than before when it was operating at maximum power.

The condition is hundreds of degrees higher, which naturally puts greater stress on the engine.

At the same time, when the engine entered the anaerobic working state, everyone in the monitoring room was shocked, staring at the engine in front of them, praying that there would be no problems with the engine.

Time passed by, everyone looked at the virtual engine, fearing that something would go wrong, and they didn't even dare to blink. Everyone felt that today's time was really very long, as if every second

It seemed like a long time passed.

Five minutes, ten minutes, fifteen minutes, twenty minutes after the engine entered anaerobic operation, the monitor finally sent a report.

"The engine temperature has reached the limit. Will it enter the cruising state?" the monitor reported.

After listening to the monitor's report, everyone realized that the engine had directly entered the anaerobic working state at the highest power level instead of the cruising working state. This gave everyone another idea of ​​​​this engine.

With the new understanding, it is no wonder that the temperature of this engine reaches the extreme.

"Stop testing the car!" Xiang Juncai said.

20 minutes, if calculated according to ampere seconds during general engine test, then the engine has been working directly at the highest power working state for 1200 seconds in an anaerobic environment. To the people in the monitoring room, it seems like it has passed

Like half a century.

When the monitor pressed the stop button, the screaming engine suddenly stopped working. This made everyone feel a little uncomfortable, but at this moment everyone let go of their high spirits.

However, everyone also knows at this time that if this engine has been tested for 1200 seconds in an oxygen-free environment at maximum power, it means that this engine has experienced the most stringent test test, which means that this test run has been successful.

.

After waiting for a while, Zhang Yi came to his senses and found that everyone was staring at him. He knew that everyone was waiting for him to announce the final result of the test run.

So he excitedly said, "I declare that the second test run was a complete success. Our engine has withstood the most severe test test."

After he made the announcement, Zhang Yi let go of his hand that had been clenched into a fist, and he realized that his palms were already covered in sweat.
Chapter completed!
