Vol 6 Chapter 3233: The whole process of rocket repair and refurbishment
Latest website:
Rocket Doctor is quite vivid. Wu Hao smiled and praised after hearing this interesting title.
Haha, in fact, it’s just for my own entertainment. Chang Zhifei laughed at himself, and then said to Wu Hao: "We will now introduce the process of rocket refurbishment and repair in the factory one by one. First, we will go to the cleaning factory of the rocket body and fairing."
Chang Zhifei pointed to a huge white-haired square factory building in front of him, and then introduced it to Wu Hao.
Go on, go in and have a look. Wu Hao nodded when he heard this, and then walked inside the factory.
As for Chang Zhifei, he stayed with Wu Hao and continued to introduce him.
“The so-called cleaning factory, as the name suggests, is responsible for cleaning the surface of the rocket body and fairing.
After the rocket body and fairing complete the launch mission and return to land, including during transportation, they are easily contaminated by the external environment, such as dust, some debris, and even we clean up bird droppings, leaves, seeds, etc. Garbage and debris.
If left unchecked, it will easily affect subsequent internal maintenance work. Because during maintenance and overhaul, we need to open the rocket body. If the outside of the rocket body is not clear, it is easy to contaminate the internal electronic components during the maintenance process, thus causing the rocket body to launch failure.
In addition, the vertical assembly of rockets and payloads also requires a clean environment, so all incoming rocket bodies and fairings will be transported here for cleaning, and then transferred to other workshops for repair and refurbishment. "
Having said this, Chang Zhifei led Wu Hao to a covered bridge, pointed at the arrow body being cleaned below and said to Wu Hao.
"Our cleaning of the rocket body is mainly divided into three parts. First of all, the first part is high-pressure blowing cleaning, which uses high-speed air flow to blow away some small debris and debris, including dust, standing on the rocket.
After cleaning, more than 90% of the dust and debris on the rocket surface can be removed. Immediately afterwards, we need to clean the rocket body for the second time, using high-pressure cleaning solution spray to evenly sweep the entire rocket body and fairing surface, so as to remove the dirt on the rocket body and fairing, especially the dirt caused by rocket jet burning. The oil stains can be easily removed after cleaning.
After the second cleaning is completed, the rocket body and fairing will be cleaned for the third time, high-pressure hot air cleaning, using high-speed air flow to dry and blow away the remaining cleaning solution from the second cleaning, thereby ensuring that the entire rocket body and clean cleaning of the fairing. "
After the introduction, Chang Zhifei led Wu Hao to the last section of the factory and continued to introduce to him: "The rocket bodies and fairings after three times of cleaning will be transported here, and then processed using protective films. package to avoid contamination from the external environment during transit."
Following Chang Zhifei's introduction, Wu Hao looked at a rocket body that was being wrapped. The rocket body was lifted by robotic arms on both sides, and then two robotic arms started from both sides to wrap its protective film. It's actually a translucent plastic film that looks more like plastic wrap.
The entire wrapping process was very fast. It only took a few minutes for the two robotic arms, one on the left and the other on the right, to wrap the rocket body and then plastic-seal it.
The plastic-sealed rocket body will then be transported out of the cleaning workshop through a special channel.
As for Wu Hao, under the guidance of Chang Zhifei, he took the shuttle bus to the next factory building.
Compared with the cleaning workshop, this factory has stricter requirements for personnel entry and exit. Even Wu Hao had to put on white protective clothing and a mask.
"This is our restoration and renovation workshop." Chang Zhifei introduced to Wu Hao, with a hint of pride in his expression.
It can be seen that he is very satisfied and appreciative of his job and the results he has achieved.
After Chang Zhifei's introduction, Wu Hao also took a look at the repair and renovation workshop.
The first thing that catches the eye is the cleanliness. The whole space is very huge, but it presents a warm white color, and the lighting makes the whole space particularly transparent and clean.
On the four sides of the factory building, there are a total of four brackets holding the bodies of four rockets. At this moment, many scientific research and technical personnel wearing protective clothing are inspecting and refurbishing the rocket bodies.
“This place is mainly responsible for the repair and renovation of rocket bodies. The cleaned rocket bodies will be transported here, and a consultation will be conducted first.
To put it simply, it is to comprehensively evaluate the overall condition of the rocket body and determine its current status. Rocket bodies with different uses and different launch missions are in different shapes. Some are in good condition in all aspects, while others have many problems.
Therefore, the repair and refurbishment team needs to evaluate these rocket bodies. If it is no longer valuable for repair and refurbishment, then the rocket body will be eliminated. UU reading www.uukanｓhu.net
The obsolete rocket bodies will be transported to the dismantling workshop, where they will be dismantled and the reusable parts will be recycled. The unusable parts will be compressed. "
“As for rocket bodies that are in good condition and meet the requirements for repair and refurbishment, and can be reused, all the problems that need to be repaired and renovated will be marked.
It is then handed over to engineers and technicians to repair and renovate it to a standard that can be used again.
Of course, this isn't over yet. First, the consultation team here will re-inspect and evaluate the repaired and refurbished rocket bodies to find out and fill in the gaps.
The problems found will continue to be returned for repair. If no new problems are found, the rocket body can be transported out from here.
Of course, this does not mean that it can leave the factory and be reused.
All repaired and refurbished rocket bodies will be transported to the laboratory for secondary testing. This is the last inspection of the rocket body before leaving the factory, and the process is very strict.
Only rocket bodies that are 100% compliant with the standards and have no problems will receive a factory certificate. Then, the rocket body will be repackaged and stored in the rocket storage warehouse.
The stable storage environment with constant temperature and humidity is conducive to long-term storage of these rocket bodies.
When rocket bodies are needed, someone will come with a list to transport these rocket bodies.
Of course, depending on the storage time, we will also conduct a test after taking the rocket body out of the warehouse to ensure that there are no problems before it is allowed to leave the factory.
We adhere to one principle during the entire process, that is, we will never let rocket bodies and fairings with problems leave the factory, and we will never let rocket bodies and fairings be launched with faults. End of chapter)
