Rebirth 2008: I Can Make Money Reading

The genius remembers the address of this site in a second: [Aibilou]https://The fastest update! No ads!

The development of the Xinghuo-1 rocket engine did not take long, less than a year, and Mu Yang had been looking forward to it for a long time. October 27,

Mu Yang took the super yacht Xifan to the rocket launch base.

Leng Han and Jin Wei knew about the project that the teacher was working on, and they also wanted to see the rocket engine test, so Leng Han mentioned it to him, and Mu Yang agreed without thinking too much, and asked them to go and see it with him, as if it was After learning, let them travel by the way.

The Xinghai Group headquarters base is quite far from the rocket launch base. It would take more than three hours by car, and then half an hour by speedboat.

If you are driving a yacht, the time will be longer, and it will take six hours if the speed is fast. However, the car is tiring.

If you take a yacht, you can lie in bed and rest.

There are many guest rooms on the yacht. Mu Yang and his students set off at seven or eight o'clock in the evening, and they will be there the next morning.

When these eight students knew that they could go to the rocket launch base with the teacher, and even ride on the teacher's yacht, they were so excited that they almost went to heaven.

One night, a few of them sat on the top of the yacht watching the night view and chatting together. "Senior Sister is so amazing, she dared to ask the teacher to play."

"What are you playing or not? I just want to visit the rocket launch base and see how the engine is tested. Really, you senior sisters are very easy to learn, do you understand?" Leng Han blinked, "If I didn't bring it up, You guys have a chance to come out and observe with me."

Xie Weizheng didn't want to expose the senior sister's words anymore, and said with a crooked mouth: "Senior sister is indeed amazing, I have also been on a yacht, especially such a super yacht, I enjoyed it so much."

"I've never sat in it before. If it wasn't for the teacher's student, I wouldn't have had the chance in this life. It's much more comfortable than sitting in the Future 01, even in this weather, where the sea breeze blows and it's cold." Jin Wei also said.

"The teacher still has a private jet, but I think it's more comfortable to take a yacht, and it's more comfortable than taking a future. Otherwise, the teacher will go directly by car."

These students chatted until twelve o'clock in the evening before returning to the client to rest. The speed of the yacht was not fast. It was only in the early morning that the yacht arrived at the seaside of Ningcheng.

In the early hours of the morning, the yacht Xifan sailed to the rocket base.

At eight o'clock in the morning, the yacht docked at the pier.

The wharf of the rocket launch base has been built, which can berth ships with a capacity of less than 10,000 tons. It has a dedicated berth and two regular berths.

Xinghai Group commissioned the construction of a professional rocket transport ship, which can directly dock with the dock. The rocket transport vehicle on the transport ship can drive to the dock and then drive to the rocket launch base.

After the yacht approached the pier, the rocket base arranged vehicles to pick up Mu Yang and others.

Mu Yang went to the pier and asked the driver to stop for a while. He walked around to observe the construction of the pier.

In order to facilitate the stable connection between the transport ship and the wharf, prevent the unstable center of gravity caused by the transport vehicle passing the bow, and the unstable water level all the year round, the wharf is built into a closed type. After the ship enters the special dock, the dock is closed, and the water level in the dock can be raised and lowered. The plane is level with the plane of the ship, and then it is connected and locked to fix the ship before the transport vehicle drives onto the dock.

If it is replaced by other non-specialized transport ships, it cannot be connected and locked with the wharf. To the east of the pier, that is the direction leading to the rocket base.

Mu Yang got back into the car and asked the driver to drive to the rocket base.

The hardened road from the wharf to the rocket base is 30 meters wide and one to two kilometers long, with greenery planted on both sides of the road. After driving about two kilometers, we arrived at the entrance of the base.

At the entrance, several security guards stood firm to prevent non-staff personnel from entering the base. Seeing that it was Mu Yang coming, the security personnel saluted and let the car pass.

The base has a launch control center, the so-called office space, a launch site (platform for launching rockets), two test sites, three launch inspection workshops, two rocket recovery sites, ground observation stations and living places for employees .

The test site is adjacent to the rocket launch site and away from other buildings.

After the rocket is inspected in the inspection workshop, the rail platform vehicle is dragged to the launch site along the constructed track. The distance between the two places is about 500

rice.

After Mu Yang arrived at the base control center, he communicated with the project manager Ye Fan. "Manager Ye, how are you getting ready?"

"Chairman, everything is ready, waiting for the ignition test." Ye Fan replied respectfully.

His tone was three points excited, seven points tense, and the pressure was very high. Today is the end of more than a year of hard work. Mu Yang nodded, and went to the command center of the control center with him.

And his eight students followed behind him like little bugs, looking around curiously. Through dozens of screens in the control center, you can see all the conditions of the test site.

At this time, Xinghuo-1 has been fixed on the test bench.

Since the thrust of Xinghuo-1 is very large, the theoretical maximum thrust can reach 1,000 tons. If the strength of the test bed is not enough, the test bed must be lifted to fly when the engine is at full thrust.

When the rocket engine burns at full power, it consumes a lot of fuel. For example, the F1 engine used in the Saturn V consumes two to three tons of kerosene per second.

Even if Xinghuo-1 saves fuel, it still consumes a lot of fuel at full thrust. However, the ignition test time is very short, only 200 seconds.

And these two hundred seconds, if it is actually launched, is enough to carry the satellite to a space of several hundred kilometers. The rocket engine test bed is far away from the launch center, so even if an accident happens to the rocket, the safety of the launch center can be guaranteed.

"Brother, what is the pool under the engine for?" Leng Han asked a researcher at the scene, pointing to a picture on the screen.

"Oh, the pool you mentioned is called the guide tank.

Its function is to shunt the energy generated by the rocket launch, so as not to affect the launch. The heat generated by the launch quickly evaporates the water in the diversion groove to produce white gas. The diversion groove protects the rocket.

In addition to the cooling effect, it also has a noise reduction effect.

The white smoke we see is mainly the condensation of oxygen after the water vapor in the environment is vaporized by the discharged liquid oxygen, and the white particles produced by the propellant reaction. "

"So it's like this, no wonder." Leng Han suddenly realized, and finally understood. The other students were not as bold as Leng Han, so they watched quietly.

There was something Leng Han didn't understand, and when she saw which researcher was free, she asked directly. At this time, the teacher will be busy, and she dare not disturb the teacher.

There are many items to be verified in the rocket engine ignition test, mainly to verify its reliability, safety and performance.

In addition to the above, some tests are also carried out to verify the ability of the rocket engine to withstand extreme working conditions, such as high and low ambient temperature, changes in fuel composition, various vibration environments, or changes in wet, rainy, and vacuum environments.

In order to verify safety, artificial faults, false signals or processing defects are sometimes introduced to the propulsion system to test the ability of the control system or safety device to handle and prevent possible failures.

At about nine o'clock, after Mu Yang knew that the preparations on the site were about the same, he gave an order: "Manager Ye, start the ignition test."

The person in charge of the project, Ye Fan, heard the chairman's order, with a solemn expression, and shouted to the test personnel: "Check the launch site!"

This is a normal process, even if it has been checked countless times, you still have to follow the process.

After the tester presses the procedure, the test site will broadcast the shout "Prepare for the test, please leave the site for irrelevant personnel". After repeating it three times, it is confirmed that there is no personnel on site before proceeding to the next process.

"Report, inspection is complete, everything is safe."

"Check fuel reserves, air pressure..." --

After ordering one after another, Ye Fan saw that a series of instruments and display lights were normal, and reported that everything was normal, and he could proceed to the next step, and solemnly shouted: "Start the ignition! 1% thrust test run."

At this moment, everyone's eyes were fixed on the bottom of the engine on the screen.

Leng Han and the other eight students saw the solemn faces of the teacher and Manager Ye, as well as other scientific researchers. They felt that the atmosphere in the entire control center was very vertical, and they didn't dare to make a sound, for fear of disturbing their work.

Suddenly, the lower part of the engine lit up, and then several light blue flames spewed out. The Xinghuo-1 engine has a large central nozzle surrounded by 9 small nozzles. Seeing the blue flames emanating from the nine nozzles, everyone relaxed a little.

"Increase by 1% every three seconds, and gradually increase the thrust! Check the thrust response speed." Ye Fan gave another order, and one operation after another began to run.

The micro-adjustment of the ten nozzles has not been tested yet, just to test whether it can be ignited normally. From the images captured by the on-site camera, the length of the flame is getting longer and longer.

After about 60 seconds, the thrust had increased to 21% of theory.

Due to the rapid increase in thrust, no data was reported, and it was too late to report.

However, the thrust of the engine is displayed on the center screen. 101KN,

200.1KN, 299.9KN, 400.0KN,...2001.3KN...3002.1KN

Just when the thrust reached over 300 tons, suddenly,

A pipe carrying liquid hydrogen above the engine caught fire. "Manager Ye, the liquid hydrogen valve is leaking!"

The observer had just finished calling out the reminder, and the flame seemed to have been drained, and it increased tenfold in an instant. There was a "boom", and then the flame covered the entire engine.

This sudden abnormality frightened everyone in the control center.

The reaction between oxygen and hydrogen is very fast, and the scene just now is only a second or two.

Mu Yang also saw the accident, but he didn't remind him to see how the on-site personnel dealt with it.

After being stunned for a moment, Ye Fan shouted: "Quickly shut down the fuel delivery, close the fuel valve, and water to cool down."

There is still a preventive plan. The project team is prepared to do what happens first after any accident occurs. They have conducted many trainings, otherwise everyone will be in a hurry and caught off guard.

The moment Ye Fan yelled, the operator immediately pressed various control buttons. The main fuel delivery valve is closed,

The valve of the high pressure water gun is opened,

Multiple control valves can be said to be executed at the same time, the engine is filled with water mist, the fire is rapidly reduced, and then extinguished. Ye Fan breathed a sigh of relief when he saw the flames extinguished, but his face was already disheartened and turned slightly pale.

It can be said that if it is a few seconds later, the flames may reach the fuel tank. Even if there are flame retardant measures, he cannot guarantee that there will be no accidents.

At the same time, the engine combustion chamber may explode.

As the main person in charge of the project, Ye Fan's eyes were red and he felt very guilty. After preparing for such a long time, there was an accident!

If the rocket is officially launched, where there are so many remedial measures like the test, the rocket must be finished. If it is a manned rocket, there is nothing wrong with it.

Ye Fan rubbed his bewildered face with both hands, quickly adjusted his state, and bowed his head slightly to Mu Yang who was standing beside him with a calm face: "Chairman, I'm sorry, I didn't expect an accident, this is my responsibility."

When Mu Yang heard this, he didn't blame him: "It's okay, I said it before, it's very difficult to succeed in the first test."

If he hadn't dealt with it in time just now, or even shirked responsibility at the first time, he would definitely have to take down his manager position.

There is no person in charge who dares to take responsibility, and he is not worthy of being a leader; he is in a hurry in the face of unexpected situations, and he is not worthy of being a leader.

Hearing the chairman's comforting words, Ye Fan still had trouble with himself: "Chairman, I will investigate the root cause of this accident as soon as possible to prevent it from happening again."

Mu Yang "hmm" for a moment, patted him on the shoulder, and said to the dozens of dejected scientific researchers around him: "We must be mentally prepared to fail at any time in scientific research, and this failure is a normal situation.

Seriously, success is accidental.

Cutting-edge science and technology research and development, how can it be successful after a few attempts, and I don't expect you to succeed a few times, and you are even ready to fail for a few years.

It is normal for our company's materials research institute to fail hundreds of times.

Failure is also an experience, but if you fail, you cannot prevent it from happening again

, that is failure;

If the grudge is gone, it is truly a complete failure. "

He sighed inwardly. For such a long time, no matter what sample test, he basically succeeded at the first attempt, and he was used to success at the first attempt.

However, Mu Yang has long been mentally prepared and has rich experience, knowing that it is not a good thing to always succeed at one go.

"Manager Ye, cut off the fuel. You need to check repeatedly and carefully. You must ensure the safety of the personnel before investigating the root cause. The more sudden the situation, the more calm you must be, otherwise it will cause a greater disaster." Mu Yang. After speaking, he waved Ye Mufan to deal with the accident.

With a heavy face, Ye Fan quickly summoned the relevant persons in charge: "The people in each group quickly cleared up their emotions, if they still can't figure it out, go to the bathroom and pour cold water to wake up.

Let me emphasize that according to the chairman's order, personnel safety comes first!

If anyone loses the chain on personnel safety matters, don't blame me for not recognizing people! Break up the meeting! "

After speaking, he himself will go to the launch site to take a look.

When Mu Yang saw Ye Fan leave, he was leaving too, and Ye Fan would tell him when the result came out.

He is not interested in going to the scene to check the problem, let Ye Fan deal with it slowly, so as to give his subordinates a chance to grow.

Leng Han and the other eight students saw the accident and knew that they couldn't help at the moment, so they had to stand aside and not disturb everyone.

Seeing the teacher leave, they followed suit. This time, it was too shocking for them.

Back on the Xifan yacht, Leng Han saw the teacher sitting silently on the sofa, offered to pour tea for the teacher, and asked concerned: "Teacher, are you still thinking about the accident just now?"

Mu Yang shook his head and smiled lightly: "No, it's a good thing they made mistakes. Do you think I'll be happy if they succeed once?"

"Oh, Mr. UU Reading www.uukanshu.com, is there another way to say this?" Leng Han also laughed along with his head.

Mu Yang took a sip of tea before explaining softly: "I would rather they fail a few more times and learn a lesson until they are unforgettable.

Rocket launches are very risky, especially manned rockets.

If they haven't failed, they will relax over time. If a launch accident occurs, it will be difficult for us to bear the consequences, especially the lives of astronauts, and we can't make fun of their lives. "

"Oh, I see."

Leng Han nodded and left.

Seeing the students leave, Mu Yang sighed again. The engine failed to ignite this time, and the Star Network project may be affected. However, it takes time.

The ignition test is not without results. Judging from the ignition thrust, it proves that the full-flow staged combustion theory is feasible to use liquid hydrogen + liquid oxygen fuel.

If this solution is not feasible, then it is really troublesome.
