　　Fan Wubing suddenly felt more entangled in his heart when he heard that there was a problem with the rocket.

　　 This incident reminded him of what he had learned before the rebirth about the Changer Bundle launching Austar, something really went wrong. At that time, when the Austar launched and ignited, an engine of the first-level rocket body shut down inexplicably after working for a few seconds, causing the rocket's thrust to be abnormal. According to live video, the rocket bounced upwards slightly after it ignited. Later inspection showed that one of the supporting legs of the rocket was offset, just a little bit, and the rocket would fall.

After the accident, rocket engineers and technicians after nearly a month of inspection and analysis confirmed that the cause of the failure was that after the booster engine was ignited, the first and third booster engine’s oxidant auxiliary system cut-off valve electric blast tube accidentally exploded, causing the first and third booster engines to explode. The booster engine shuts down. The accidental explosion of the electric blast tube is due to a trace of aluminum excess on a control contact of the program distributor in the ignition control circuit. If it were not for the rocket's safety guarantee system to brake in time, the launch vehicle would take off within a few seconds, and the consequences would be disastrous.

　　 There are only a handful of countries in the world that can use rockets to launch satellites. Each country has its own braking tricks. Generally speaking, there are no more than two types, one is program-controlled and the other is grasping. The principle of the program control type is roughly that it takes a certain time for the engines on all rockets to reach the rated takeoff thrust from ignition. If the rocket has not taken off after a certain time, it proves that the rocket thrust is abnormal. Therefore, people can set a delay in the program, and if the rocket has not lifted off after the delay, all engines will be shut down immediately. The principle of the gripping style is to use some giant mechanical claws to grab the rocket to be launched, and then ignite it. When the rocket thrust is detected to be abnormal, all engines can be shut down calmly.

　　The difficulty of using the program control method is that the delay in the program is not easy to determine. In addition, the rocket may overturn due to the torque generated by the unbalanced thrust between its engines during the delay. The use of the gripping type can avoid the drawbacks of the program-controlled type, but the synchronization problem between the mechanical claws will also cause trouble when the rocket is launched.

　　 For example, when the other mechanical claws are released. However, if only one mechanical claw fails to move due to a malfunction, the inclination angle of the rocket will immediately change, which may cause the rocket body to explode in severe cases.

　　 Although the first Austar launch failed, the Star Arrow was not damaged. It can be said to be a great fortune. However, after later testing, it was found that the first-stage rocket had been ignited, causing the body of the rocket to be burnt. The company had to rebuild another long two-bundle rocket. The launch mission was completed almost half a year later.

　　 The launch process of the second Austar is even more weird. The long two-bundle rocket successfully put the second Austar into orbit, but the satellite did not return any signal. Later investigation showed that. This large-capacity satellite made by the Americans exploded less than a minute after the rocket lifted off. The second long bundle was sent into orbit, only the remains of the explosion.

At that time, many people were speculating that it was most likely that the Americans planned the failure and added bombs on the satellites in order to organize the Chinese who have made great progress in rocket launch technology to enter the international commercial satellite launch market. For this reason, they did not hesitate to lose hundreds of millions of dollars worth of earth satellites.

　　 Although it sounds weird. However, Fan Wubing had to prevent this situation. He was responsible for his three satellites. Therefore, while eliminating the hidden dangers of the rocket itself, he also needed to remind the relevant parties to guard against the Americans using small tricks.

　　 If a satellite is determined to be blown up before it is manufactured, then Fan Wuyao has reason to believe it. Americans will certainly not implement all functions on it. In other words, a certain satellite may be just an empty shelf. The communication function may not be realized inside, and the replacement is a bomb that explodes after being triggered.

The design of the long two-bundle rocket itself is not problematic. From Fan Wu’s memory, several failures are not a defect of the rocket itself. One is the impact of residues on key parts, and the other is the launch platform. Therefore, how to remind the base to carry out screening and key parts investigation is the top priority.

At this time, there has been a lot of hype in the small conference room. The generals and senior engineers are all discussing the problem of the failure of the rocket. On the contrary, no one mentions the news that the head of No. 1 came to inspect the site. .

Admiral 　　 quietly listened to the people arguing for ten minutes, then gently knocked on the table to stop the chaos, and then said very cautiously, "Everyone, please be quiet."

　　The people who were still arguing for a long time became quiet, but judging from the faces of everyone, everyone's mood was very uneasy. After all, before the launch, such news suddenly came out, and the impact was very big.

The admiral asked carefully, "Is a level abnormality an occasional phenomenon or a sign of a major hidden danger? This matter must be clarified. Also, in this way, can the rocket be launched on time? If it is forced to launch, How big is the risk factor?"

The chief engineer in charge of the rocket project immediately became the focus of everyone's eyes. At this time, he was also a little bit waxy. However, the person who has the most comprehensive understanding of rockets is himself. After thinking about it, he immediately said, "Before that. After many inspections, this kind of situation occurred. I estimate that this phenomenon is mostly sporadic. It is necessary to know that the sensitivity of the rocket components is very high, or the influence of temperature changes and wind direction, or even the ignition of the nearby car’s engine. The electric sparks generated at that time will have a certain impact on it and give feedback. Therefore, as long as the quality of the rocket itself can be guaranteed, an abnormal level does not explain the problem."

　　 Chief Engineer's words are considered to support the launch on time.

　　 But as the commander of the base and the admiral of the temporary commander in chief, he has to consider various factors. What if something happens?

　　 After all, the long two-bundle rocket has a criminal record.

　　 Prior to this, during the test phase of the rocket, there had been failures. This time it was about to be loaded into the satellite, but there must be no problems.

　　 "The satellite will be loaded in the morning after tomorrow, and the final debugging will be carried out, and it will be launched at night. The time left for us to troubleshoot is only two days and nights. Can this time be in time?" the base commander asked.

　　 "Hurry up, work overnight, it should be done." The chief engineer replied after thinking for a while.

　　 "Well, we will immediately conduct an emergency investigation. If no malfunction is found before loading the satellite the day after tomorrow, then launch as originally planned." Finally the base commander gritted his teeth and decided.

　　 Everyone unified their thoughts. Decomposed the task. When he was about to leave the conference room and mobilize quickly, Fan Wuyin spoke. "Everyone, please wait a moment, let me say a few words."

　　 Everyone finds it a bit strange. Launching satellites is a matter of our base, and debugging satellites is a matter of Hughes. You are indeed rich. But it's just a nouveau riche. Even if the launch is unsuccessful, an insurance company will give it to you. You can't lose much money. What's the matter with you in this place?

　　 Besides, you are a little boy, do you know rocket launch technology?

　　 Fan stood up without illness. I saw the meaning in everyone's eyes. So he raised his hand very bachelorly and said, "I know. You must all think that I am a little kid who doesn't understand rocket technology and doesn't have the right to speak, right?"

　　 Although the atmosphere is very tense, everyone still feels a little overwhelmed when they hear Fan Wu's voice just like that. This guy in Xindao is also very interesting, but I don't know what he is going to say?

Admiral 　　 was also amused by Fan Wubing. He smiled and said, "Comrade Xiao Fan is the buyer, so he naturally has the right to express his opinions. Just say it, no matter how urgent you are, it won't be a minute or two."

　　 A minute or two? Fan Wubing thought, anyway, I can solve the problem in just a few words. One or two minutes is enough, so he nodded and said to everyone, "You don’t have to discriminate against children. Even though I am young, I made it from scratch. A large piece of land, otherwise it would not be possible to buy three satellites at once. After all, although I can't count them, I still have some skills."

　　 "Comrade Xiaofan, idealism doesn't need to be preached, we don't have much time." The commander of the base looked at his expression.

"Okay, okay----" Fan Wubing said a long story short, "I also know a little about design. This time, the problem should be the control circuit of the rocket ignition. You can focus on this place and see. See what affects it."

　　An engineer immediately retorted, "The ignition control circuit is our focus of inspection. Everything is normal, and there is no possibility of any failure."

　　 Fan Wuyi gave him an angry look, and said with a bit of hatred for iron and steel, "It is naturally not the problem of the control circuit itself! But have you checked on the spot?! Open the deck to see the circuit?!"

　　 "No." The engineer shook his head. They were all inspected through instruments and equipment. Who would take apart the rocket that has been assembled to look inside? Isn't that crazy!

　　 Comrade Xiaofan is a layman for this! The admiral thought in his heart that he had been in the base for a long time, and he always understood some operation procedures, unlike he was just a guest.

But before the admiral could speak, Fan Wubing shook his head and sighed, "Then open and take a look. You will definitely find some foreign objects on the contacts of the circuit board, such as screws. I won’t say more about the tiny aluminum wires that have been unscrewed."

Fan Wubing probably already has a spectrum in his heart at this time. This rocket must be the one that was emergency stopped before launch, so the problem is naturally the same as the original one, but time is pressing, and he has no time to play with them. Those twists and turns, only pointed out in person, if they still insist on going their own way, then they have nothing to say, anyway, it is not themselves who have lost!

"Is it possible for the situation described by Comrade Xiaofan to happen?" The commander of the base asked the chief engineer. The chief engineer was taken aback for a moment, thought about the structure of the ignition control circuit, and then replied thoughtfully, "If it is true. Then a small amount of metal foreign objects falling on the contacts of the control circuit will indeed cause an abnormal level. But this kind of situation should not happen, right? Even the screws are selected by thousands, how can there be aluminum The silk is unscrewed?"

"Since there is such a possibility, then go to work." At the critical moment, the admiral said, "There are some things. We didn't do it because we didn't think of it. But what we thought of, we must do it. If we do. It is really because a little bit of aluminum wire affects the launch of the rocket. This lesson is too painful!"

　　 Fan Wushu then interrupted. "In fact, details determine success or failure."

　　Fan Wubing's remarks are of course not a good-for-nothing, but a real truth.

　　 There have been many air crashes in the world's space history. Basically, it is caused by mistakes in some details.

for example. In 1961, the astronaut Bondarenko, who was determined to be the first Soviet voyage in space, conducted intensive training in a cabin filled with pure oxygen, while resting. After rubbing the part where the sensor was fixed on his body with an alcohol cotton ball, he threw it on an electrode plate. As a result, a fire broke out in the cabin. He was severely burned and died ten hours later, becoming the first manned spaceflight activity. An astronaut in a disaster area.

　　 In 1974, the United States used a Delta rocket to launch the British Skynet satellite. A small piece of insulation peeled off near a small solder joint on a printed circuit board in the rocket's electronic device. Causes a short circuit, and the launch fails. In 1980, during the second test flight of the Ariane rocket, a staff member accidentally touched the trademark of a component, which blocked the nozzle of the engine's combustion chamber, causing the launch to fail. In 1985, the United States launched the Trident missile. Because a piece of soy bean insulation was peeled off in the engine combustion chamber. As a result, the high-temperature flame burned through the metal wall there, and gas was sprayed outward. The engine exploded. In 1990, during the 36th launch of the Ariane rocket, a worker accidentally left a wiper in the water circulation system of the first-stage engine, blocking the pipeline and causing the rocket to explode.

　　All kinds of experience and lessons show that it is usually some details that affect the progress of the aerospace industry, rather than the insufficient level of the designer or the manufacturing plant itself.

　　 "Okay, let's check the control circuit right away." The chief engineer also made a statement when meeting the general, and immediately agreed.

　　 So the people went to the rescue, and several generals stayed to discuss how to explain to the above about the rocket failure. After all, this time the No. 1 Chief is coming to inspect. Now that this kind of problem occurs, everyone is very headache.

　　 "My opinion is to report the situation first. Otherwise, when the chief comes, how can I explain it?" a general suggested.

　　 In fact, the base commander also felt a very headache to keep up with the admiral. Everything was fine before. Who knew that when the launch was about to happen, but this kind of problem occurred, it really makes people wonder what to do.

"You must report to the land, but my opinion is that it is best to find out the cause of the fault first. This situation is implemented and eliminated, and the above is more assured and satisfactory. Otherwise, our work is not in place!" Finally, the admiral made a decision.

"Don't worry~www.wuxiaspot.com~ I will be able to find out the cause of the malfunction." Fan Wuyi comforted them, but he was thinking in his heart that if you are willing to listen to my opinion, at least you don't need to be too busy. The dog jumps.

Fortunately, Fan Wuyi’s opinion was implemented, because everyone did not have any clear screening targets. Since some people said that the control circuit may have problems and pointed out the doubts about the interference of metal residues, they naturally have to follow It was found here that half an hour after the cabin was opened, the staff found this 0.15mm thick aluminum wire on a contact of the ignition control circuit. After identification, it was indeed from a screw. It fell off!

　　At this time, the people in the small conference room have not yet dispersed. I was supposed to entertain the people from Hughes Company for a work meal in the evening. The restaurant has already been prepared, but the people here are not in the mood to eat.

　　 Suddenly the door was opened, and an engineer ran in panting, standing in the middle of the room too excited to speak.

　　 "Drink and speak slowly, what's the matter?" Everyone was very nervous by his appearance.

　　 The engineer was also present at the meeting. He turned his gaze and saw Fan Wuyi, immediately rushed up, grabbed his hand and said, "Master! Master!"

　　 Looking at the engineer's serious look, Fan Wubing suddenly stayed.

　　 Uh, big people, I really don’t know how to say it. In fact, many big people have voted for more than one monthly pass for Little Wolf. But at the end of the month, the mood is very tangled, and the little wolf has to shout again cheeky, asking for a monthly pass!
