Chapter 3233: The whole process of rocket repair and refurbishment
Rocket Doctor, quite vivid. Wu Hao smiled and praised after hearing this interesting title.
Haha, in fact, it is just for my own entertainment. Chang Zhifei laughed at himself, and then said to Wu Hao: "We will now introduce the process of the rocket entering the factory for renovation and repair. First of all, we will go to the rocket body.
and a fairing cleaning plant.”
Chang Zhifei pointed to a huge white-haired square factory building in front of him, and then introduced it to Wu Hao.
Let's go in and take a look. Wu Hao nodded after hearing this, and then walked inside the factory.
Chang Zhifei, on the other hand, 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 the subsequent internal inspection and maintenance work. Because during maintenance and inspection, we need to open the rocket body. If the outside of the rocket body is not clear, it is easy to contaminate the interior during the maintenance process.
electronic components, resulting in rocket 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, debris, including dust standing on the rocket.
After cleaning, more than 90% of the dust and debris on the surface of the rocket can be removed. Next, 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 oil stains produced by rocket jet burning, which 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 and wrapped. The rocket body was lifted by mechanical arms on both sides, and then two manipulators started from both sides to wrap it.
Protective film. It is actually a translucent plastic film that looks more like plastic wrap.
The entire winding 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 a white protective suit 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 this restoration 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 conduct a comprehensive assessment of the overall condition of the rocket body to determine its current status. Rocket bodies with different times of use and different launch missions have different shapes. Some are in good condition in all aspects, and some are in good condition.
However, many problems arose.
Therefore, the repair and refurbishment team needs to evaluate these rocket bodies. If they are no longer valuable for repair and refurbishment, then the rocket bodies will be eliminated.
The obsolete rocket bodies will be transported to the dismantling workshop, where they will be dismantled and the reusable parts will be recycled, while the unusable ones will be compressed."
"As for rocket bodies that are in good condition, meet repair and refurbishment requirements, and can be reused, all areas with problems that need repair and refurbishment 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 is not 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 inspection. 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 bodies 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 have adhered to one principle throughout 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."
