Chapter 502 The reason is found
Following this direction, Xu You simulated it several times from beginning to end and confirmed that there was nothing unreasonable.
"Although we cannot be sure that this is the ultimate cause of the accident, it is at least very likely."
If we want to determine the specific cause, we have to wait until the wreckage of the rocket is found.
In fact, such a situation is not particularly strange.
The Space Launch System used in Sam's moon landing program is of a completely new generation.
The design of the entire new system has little in common with the launch system used during the original moon landing.
There will be some failure cases in rocket launches of all countries to a greater or lesser extent.
Learning from failure and moving towards success is a necessary process.
After completing the analysis of the entire process, Xu You used the modeling software on the computer to simulate the entire process again.
At this time, Xu You really wanted to hold a meeting immediately to discuss this incident with the staff of the Academy of Aerospace.
However, it was already very late today, and Xu You didn't have the heart to disturb everyone's rest, so he decided to study it tomorrow.
The next morning, Xu You found the leader of the Academy of Aerospace and explained his purpose.
"Professor Xu, are you saying that you have found the reason why Sam's rocket launch failed this time?"
"We're not 100% sure yet, but it's a very likely reason. If possible, I suggest we hold a meeting right away and study it together."
"Yes, of course! I'll arrange for someone to organize a meeting right away!"
Even if Xu You didn't say it, analyzing the reasons for the failure of the SAM rocket launch is also a task that the Aerospace Institute must do.
However, the leader never expected that Xu You could deduce the cause of the failure so quickly under the condition of insufficient information.
The leader even had some doubts, thinking that even Sam might not know the specific cause of the failure.
According to the information obtained from the satellite, it will be difficult to find the wreckage of the faulty rocket in the short term.
If the rocket wreckage is not found, even SAM Space Agency itself will not be able to determine the specific cause of the accident.
After this, everyone received instructions to hold an emergency meeting.
Everyone actually had some complaints about this sudden meeting.
The leader just instructed last night that we should quickly analyze the failure of the SAM rocket launch.
Too frequent meetings will disrupt everyone’s work rhythm.
But no matter what, the orders from superiors must be obeyed.
After everyone gathered in the conference room, the leader immediately organized the meeting.
"Last night, Professor Xu made a detailed analysis of the failure of the SAM rocket launch. Now, please allow Professor Xu to explain."
Everyone was shocked when they heard the leader's words.
"Professor Xu... have you figured out the cause of the accident so quickly?"
"The rocket launch ended so late last night. Didn't Professor Xu get any sleep?"
"Let's see what Professor Xu has to say."
Xu You did not rush to give a detailed introduction, but instead put the 3D model he made last night on the big screen.
It can be seen that Xu You's modeling is very detailed. It not only restores all the processes, but also includes the detailed data of the rocket at each moment.
Even the scenes that could not be directly observed because of the sudden interruption of the live broadcast by SAM Space Agency were restored to a high degree by Xu You through the feedback from the satellite.
After watching the entire 3D model process, everyone was secretly amazed.
At this time, Xu You said:
"The direct cause of the accident was that the rocket's acceleration after launch was insufficient and it was unable to reach the planned speed. In order to make up for the insufficient speed, the rocket subsequently increased the engine's power, causing the engine to overload, which eventually led to the engine flameout and the failure of the second-stage rocket to separate."
When Xu You explained the reason, everyone had different reactions.
Some people think that it is incredible that Xu You was able to complete the entire modeling work and analyze the direct cause of the accident in one night.
There are also a few people who believe that after obtaining the image data from the satellite, these reasons are clearly visible and can be analyzed, and it is not surprising.
At this time, an engineer said:
"Professor Xu, your model is really well done. Even without making this model, we can still see the reason very intuitively. I wonder if you have figured out the root cause of the matter?"
The engineer had no ill intentions and was simply expressing his doubts truthfully.
Some other people also have such doubts in their minds, but they just don't dare to speak them out.
Hearing the engineer's words, Xu You said calmly:
"That's right. The direct cause alone is not enough. The key is to find the reason why the rocket did not accelerate enough in the beginning. Don't worry, I have thought about this problem a long time ago. Please take a look at the next set of 3D models."
As he spoke, Xu You opened another 3D modeling file and played it on the big screen.
Unlike the previous model, this model shows the scene inside the rocket during the launch process.
Some careful people have noticed abnormal conditions inside the rocket during this period.
"The fuel in the fuel chamber is slowly leaking out?"
After posting this modeling file, Xu You displayed two models at the same time.
When these two videos were played at the same time, everyone was surprised to see that the changes inside and outside the rocket were completely consistent.
"Yes! This can indeed explain why the rocket has a low acceleration rate after launch, and why it stalls quickly after the engine power is increased."
At this moment, those who had doubts about Xu You just now immediately dispelled all their doubts.
Seeing that everyone's emotions gradually calmed down, Xu You continued:
"Since we don't have enough information to prove this hypothesis, this inference is only a guess now. I think it may be that the inner wall material of the fuel chamber, under extreme circumstances, had some cracks, which led to the accident. In the absence of sufficient information, I think this inference is most likely to be true."
After listening to Xu You’s detailed explanation, everyone felt that this inference was indeed very likely.
In the following time, everyone continued to discuss the accident and put forward some other possibilities.
However, compared with Xu You's speculation, the possibility of these possibilities being true is much lower.
