Domestic car manufacturing is weak, what does it have to do with our land tanks?

“In this case, as long as it passes the quality inspection scan, we can directly enter the ignition test.”

Lu Yan said.

Unlike the others who were relieved, he always had a relaxed smile on his face. He even felt that building a rocket engine was not much more difficult than building a car engine.

It’s just a little bigger and the fuel is more expensive. Of course.

This conclusion is obviously irresponsible.

The whole process was so smooth mainly because he had a complete set of rocket assembly technology and a comprehensive engine internal data map in his brain. The system can not only derive the principles of the entire set of technical groups, but also allow Lu Yan to quickly understand and master a set of technologies in his brain.

So now, he feels like lifting a heavy weight when coordinating the ignition of the rocket engine.

Following Lu Yan’s command, the scanning and quality inspection process of this”Hongqi F1 rocket engine” was carried out quickly.

After half an hour of the process, the entire rocket engine was finally confirmed to have no problems from the hardware and all electronic sensors.���Wire errors, omissions and anomalies.

Next.

The entire rocket engine is packed up and transported to the rocket engine test bench by a special vehicle.

This step is of utmost importance.

As the power unit of the rocket, the engine is the absolute heart of the rocket, and the quality of its working performance directly determines the operation of the entire rocket.

However, to fully and stably test the engine ignition performance and obtain the most accurate thrust data when it is working, the accuracy of the”rocket engine test bench” is truly tested.

The horizontal test bench can eliminate the influence of the engine mass and gravity on the thrust measurement mechanism during the test.

The vertical test bench can accurately measure the control force and interference force acting on the engine when the servo control mechanism is working.

“The data collection and processing capabilities of the”rocket engine test bench” directly determine the control accuracy of the rocket engine by the land main control when the rocket is ignited and launched in the later stage. Therefore, not only the construction strength must be qualified, but the entire calibration system cannot tolerate any error!!

At the Hainan Space Launch Site, the”rocket engine test bench” built this time was mainly built by the Sixth Academy of Aerospace, which happens to be the domestic dual-station 700-ton engine test bench with the largest thrust.

It fully meets the abnormal performance of the”Hongqi F~1″ rocket engine!!

After the”Hongqi F1 rocket engine” was transported over, the initial construction and test installation process took another three days. Time came to the morning of the fourth day.

Lu Yan and a group of space administration teams gathered in front of the”rocket engine test bench” in the test area of the Hainan launch site.

A large rocket engine test bench like this is also called a”test bench” in the aerospace industry, and can also be understood as the step of testing the engine before installation.

The place where Lu Yan and his group stood was a general control survey platform.

Here you can most intuitively see the operation of the entire general control system and the working conditions of the rocket engine when it is ignited.

And in front of them.

It is a huge liquid rocket engine test bench, cast by large raft concrete steel bars, with a total weight of more than 8354.9 tons!!

“Engine electrical and hydraulic system inspection completed……”

“The test bench lubrication and cooling system, sensors and control system have been inspected!!”

“All parameters have been adjusted to the working conditions, and the rocket engine hot test will begin soon. The Hongqi F1 hydrogen-oxygen rocket engine test ignition time is 500 seconds. All departments are in place!!”

As the preparation processes are completed one by one, the rocket engine is about to enter the final ignition stage.

The ignition time is determined to be 500.

This time.

Even in the aerospace industry, it is a very large”value”.

For general rocket engines, the ignition test will not exceed 100 to 200 seconds.

In principle, the so-called ignition test cannot drive a rocket engine alive until the entire service life is exhausted.

In that case, let alone whether the”test bench” can withstand it.

The test cost alone is not low.

Therefore, the recognized standard in the aerospace industry.

It is based on the basic premise of not damaging the life of the engine, covering the high and medium working conditions of the engine. , low working conditions, to get the best inspection test data.

To obtain this data, 120 seconds is enough.

Of course.

The rocket engine designed by Hongqi has a service life far exceeding that of ordinary rocket engines. According to data calculations, if everything goes well, it can be reused dozens of times. It is not an exaggeration to say that it is the best among all!!

Therefore.

The starting point of the first test is naturally high!! (To read the violent novel, go to Faloo Novel Network!)

Everyone present looked at the”test bench” with cautious and nervous expressions!!

If the ignition is successful and the data is normal.

Then China Aerospace will really open a new chapter!!

“”Mr. Gong, why don’t you take charge of the ignition order?”

Lu Yan stared at what was in front of him and suddenly said[]

He could tell that Mr. Gong, who was in charge of China Aerospace, was looking forward to this ignition test even more than he was.

“”Okay!”

Gong Nanjiang nodded, not hiding his expectation.

Their generation of astronauts has been waiting for this day for too long!

Even if they have been calm for decades, they can’t suppress their emotions.

They said decisively:

“”Ignite!”

An order was given.

Fuel was loaded – boom!

“The”Hongqi F1 rocket engine” was officially ignited and started.

At first, it sounded like a huge kettle boiling. This was the sound of the internal valve opening, the high-pressure turbine pump started to run at full speed, and a strong gas spurted out of the bottom nozzle!

At the moment of ignition, a rapid vortex-like blue flame tail burst out wildly!

The rumbling sound and huge thrust formed bombarded everyone’s eardrums, causing everyone to start to be excited!

You can see that this blue flame tail, under the condition of increasing power, gradually turned into a blue flame column!

The high temperature and air convection generated made the temperature of the bottom nozzle rise rapidly, from its own color, gradually turning red, and finally becoming completely heated and red, as if the bottom was about to melt!!

“Ten seconds……”

“Thirty seconds……”

“Fifty seconds!!!”

All the astronauts present stared intently and held their breath!

They kept looking at the data.

Fifty seconds after ignition, the engine thrust gradually burst to the maximum!!

From this, various sensor data and thrust values were generated (excellent) and also transmitted from the test bench.

“520 tons of thrust!!”

…………

“”Hiss!!!!”

The astronauts present took a deep breath!

Although they already knew the R&D value of this engine, they were still shocked by this thrust value.

This is definitely the liquid hydrogen rocket engine with the largest thrust in the world! Cool!

No one else!!!

You know, the Merlin engine on the Falcon 9 built by Musk only has a thrust of 83 tons per unit. It took 9 Merlin engines to successfully propel the Falcon 9 into space.

And now,

Hongqi has only one liquid hydrogen rocket engine, which has reached the 500-ton level!!

Although it adopts a three-tube thrust chamber design, the total volume is much larger than that of the Merlin engine.

But only two units are connected in parallel. It can easily propel a carrier rocket like the

“Falcon 9” into space, and the total volume is much smaller!..
