Chapter 740

When Director Bi touched his chin and pondered.

The liquid oxygen kerosene engine designed by Gu Lu was sent into a vacuum chamber.

Outside the vacuum.

Many of the technicians who rushed to hear the news looked inside curiously and whispered something about something.

Director Bi coughed lightly.

The surroundings immediately became quiet.

As the leader of this rocket research and development base, Director Bi's prestige is still quite high.

Director Bi turned his head to look at the assistant beside him and said softly, "Let's start the ignition test." ”

The assistant nodded.

Then trot all the way to the control center on the other side of the vacuum chamber.

"The 354th test of the liquid oxygen kerosene engine, start!"

After all that's said.

The assistant pressed the ignition button of the engine.

Rumble!

After a roar.

The entire liquid oxygen and kerosene engine in the vacuum chamber began to run at high speed, and a dark blue flame was sprayed from the bottom.

Meanwhile.

The data of the operation of the liquid oxygen kerosene engine is also transmitted to the control panel of the vacuum chamber.

Since this liquid oxygen kerosene engine was only filled with a thousand pounds of fuel.

So.

It only took about thirty seconds for the engine to stop running completely.

Once the engine is fully fueled, it can run for almost 150 seconds.

At the end of the run, all parameters and data of the run are transferred to the control room.

Director Bi and Gu Lu have no way to see these data parameters in real time.

Seeing that the assistant had not sent the printed data form over for a long time, Director Bi shouted to the control room of the vacuum room.

"Xiao Zhang, what are you rubbing, don't you hurry up and send me the printed parameter data!"

After a few seconds of silence.

The assistant Xiao Zhang's voice came from the control room, "Director, I think, it's better for you to come in and take a look in person." ”

Director Bi was puzzled for a moment, and then walked into the control room, muttering something, "What are you doing again, I can't do such a small thing when I give it to you, what do I want you to ......?"

Director Bi was halfway through his sentence when his voice stopped abruptly.

"How is this possible!"

Immediately afterwards, Director Bi's voice of increasing a few decibels came out of the control room.

The engineer standing outside thought something was going on inside, and hurried into the control room.

And then......

What I saw was Director Bi holding a page of parameter data sheets, his eyes widened, and he looked incredulous.

Like, yes.

It's like seeing something incredible.

"Director Bi, what's the matter?" Director Nie asked as he approached Director Bi.

Director Bi's hands trembled a little and handed the form in his hand to Director Nie, staring at Gu Lu not far away with a thick and complicated look in his eyes, and said, "Take a look for yourself." ”

Director Nie took the form and glanced at it cursoryly.

Afterwards.

The pupils that reacted almost like Director Bi shrank suddenly.

"Vacuum thrust 7421KN, vacuum specific punch 325S!"

Director Nie could hardly suppress his excitement and read out the two data, causing an uproar in the entire control room.

Vacuum thrust 7421KN, vacuum specific punch 325S!

It is impossible for all of you to know what these two figures mean.

It's been mentioned before.

In order to successfully launch the Long March 9 launch vehicle, the requirements for the liquid oxygen and kerosene engine are that the vacuum thrust is not less than 7000KN and the vacuum specific impulse is not less than 300S.

Now, these two figures of this liquid oxygen kerosene engine are even more than these two figures.

In other words.

The liquid oxygen and kerosene engine designed by Gu Lu can be directly installed on the Long March 9 launch vehicle.

A problem that had plagued the entire project team for more than three years was solved by Gu Lu alone.

But......

How unrealistic this sounds!

Could it be that the test data is wrong?

Most of the people present, including Director Bi, had this kind of speculation in their minds.

Thereupon.

In order to confirm this idea, Director Bi immediately instructed his assistant.

"Having someone bring in 2.5 tonnes of fuel, fill me up with the whole liquid oxygen kerosene engine, and then retest it again, I need an accurate data. ”

Something like a liquid oxygen kerosene engine is generally not a disposable.

Under normal circumstances, a liquid oxygen kerosene engine can run about five times.

However, considering that Gu Lu's engine was made from some discarded materials, it is estimated that it will be almost completely scrapped after being used twice.

But that's totally okay.

As long as Gu Lu, the engine maker, is still there.

............

2.5 tonnes of fuel was quickly transported and then loaded into the engine's fuel bunker.

In order to avoid too much error, Director Bi didn't worry about the money this time, and directly chose to burn all the 2.5 tons of fuel.

Before testing again.

Director Bi came to Gu Lu.

"Professor Gu, is this result within your expectations?" Director Bi looked at Gu Lu with flickering eyes.

"Nope. I didn't expect the test results to be so good either. Gu Lu spread his hands, "I thought that I could barely meet the requirements of the Long March 9 rocket, but I didn't expect it to exceed a lot." ”

Director Bi: "......"

Can I say, are you showing off!

Director Bi tugged at the corners of his mouth and came to the console.

Whether this Professor Gu is pretending to be coercive or really awesome, we will find out later!

"Ignition!"

This time, it was Director Bi who personally pressed the ignition button of the engine.

Flames began to rise at the bottom of the engine.

Everyone stared at the screen in the center of the control room.

On this screen, data on various parameters of the engine while operating begins to appear.

[Vacuum thrust: 6547KN...... 6824KN...... 7054KN...... 7451KN......】

The vacuum thrust of the engine remains above 7000KN for the rest of the time, except for the first few seconds when the engine starts to fuel, which is below the 7000KN mark.

THE SAME IS TRUE FOR VACUUM IMPULSE, WHICH IS BASICALLY KEPT ABOVE 300S.

Control room.

As the numbers jumped again and again, everyone's breathing began to become rapid.

"It's so strong!"

It's not just who broke a foul word, but it got the compound of many people in the control room.

One hundred and fifty seconds is a short time, and a long time.

In a word.

150 seconds passed like this.

The engine stopped running because it ran out of fuel.

The average data after calculation is also presented in front of everyone.

[Vacuum thrust: 7385KN, vacuum specific impulse: 323S]

It's almost the same as the last test.

OHHHHH！！

A cheer was remembered in the control room.

Director Bi looked at this set of data, his face turned red, and his excitement was indescribable.

It worked!

It really worked!

Although the process was a bit bumpy and nonsense, the result was a success.

If the results of both data tests are the same, then there is no possibility of false detection.

It's just that......

When Director Bi thought that this liquid oxygen kerosene engine was completely developed by Gu Lu alone, he felt a faint sense of worry!
