A big country of aerospace with black technology

The rocket platform used to launch ChinaSat-8 is the same series as the rocket used in the last failed launch.

They are all Changsan series rockets.

However, the Changsan rocket used for the first launch last time will be used this time with the Changsan rocket that has been developed for a longer period of time.

As an old-model rocket that has been developed and applied for more than ten years, all aspects of it are relatively durable.

Compared with the new generation of Changsanyi, Changsan is inferior to him in all aspects.

But it is such a battle-tested rocket that will be eliminated in a few years.

Because its thrust is too small, the payload of the GTO is 1.45 tons, which is far inferior to the Chang Sanyi, which has a carrying capacity of 5.5 tons, and cannot meet the increasing launch load requirements.

However, this time it is a single-satellite launch, and the carrying capacity can still meet the launch requirements.

As the first rocket launch mission since the failed rocket launch in February, everyone at the Rocket Research Institute attaches great importance to it.

This is especially true for Factory 112 as a rocket engine manufacturing plant under the Rocket Research Institute.

Although the reason for the failure of the last launch has been identified, it is not their problem.

But they still hold the attitude that they can't make a little mistake.

After all, as mentioned before, unqualified valves will be sent back as qualified products without any maintenance when they are returned for maintenance.

This incident happened in Factory 112.

After the accident, when the accident was investigated, dozens of leaders in the entire factory were held accountable for this incident.

Because of this, the factory manager went straight to the end and was assigned to a factory in the border area as a general worker.

"Director Chen, how is the factory preparing for this launch mission?"

Zhang Xingyang wandered around the workshop and asked while looking at it.

As Chen Chunming, who just replaced the former factory director who was sent to the frontier, wiped the sweat from his brow, and said nervously:

"Everyone attaches great importance to this upcoming launch mission. The parts in each system have been checked several times to ensure that there are no problems!"

"I've seen your resume. You used to be the director of the rocket launcher production unit?"

Zhang Xingyang raised a seemingly irrelevant question.

"Yes, yes, I was originally at the Second Machinery Factory in Western Henan."

The factory is very hot in summer. Although the fans on both sides of the factory are blowing non-stop, I still feel the heat flow around me.

Although both the Rocket Research Institute and the Second Yuxi Machinery Factory belong to the Aerospace Industry Corporation.

However, there is still a big difference in the level of the Rocket Research Institute directly under the head office and the Yuxi Second Machinery Factory affiliated to Yudi Aerospace.

So although the 112 factory seems to be a hot ass place now, for Chen Chunming, it is definitely considered a high promotion.

"The Second Yuxi Machinery Factory, if I remember correctly, should produce multiple rocket launchers."

Of course, Zhang Xingyang, who has the skill of photographic memory, will not remember wrongly.

"Although rocket launchers and rockets sound like there is only one word difference, and they both use rocket engines, rockets have stricter requirements than rocket launchers, and can even be said to be more stringent."

Of course Chen Chunming understands the difference between the two, especially after he took office, he has done a lot of homework.

"Dean Zhang, although I worked in the rocket launcher factory before, I also understand that rockets are more complicated than rocket launchers, and there are more precautions."

"We have vigorously promoted the zeroing system of the quality management system, and strive to eliminate all problems in the self-inspection stage before leaving the factory."

Zhang Xingyang nodded and said:

"We must do a good job in quality management, quality is our lifeblood, and no problems can occur in any case!"

"The YF-21B engines of Changsan's first sub-level have all completed the last inspection work before leaving the factory. As for the YF-24D and YF-73 engines of the second and third sub-levels, they are still undergoing factory inspection!"

Chen Chunming was also not ambiguous, and gave the current maintenance status of each engine required by the Changsan rocket.

In fact, this speed was already beyond Zhang Xingyang's expectation.

Although these engines are commonly used in the Changsan series, they are still in stock in the warehouse of Factory 112.

But since the last accident, because of the accident investigation and disposal of many people, the production of the 112 factory has stagnated.

Therefore, these engines are estimated to be inventories produced half a year ago.

In such a short period of time, it is really not easy to re-check and repair these previously produced engines, and it seems that they have spent a lot of effort to carry out various inspections.

"During the inspection process, we ruled out hundreds of possible hidden dangers and replaced dozens of parts that may cause crises."

Chen Chunming still did the work for everyone in Factory 112 in a timely manner, and told Zhang Xingyang about it.

"Rocket Research Institute will not forget your work, and you will have many tasks in the future."

Of course Zhang Xingyang understood what the other party meant, but whether it was the production of new liquid oxygen kerosene engines or the production of previous engines, the number of orders would not be small.

Zhang Xingyang naturally wanted to urge them again:

"You should have heard that the research institute is still developing a new rocket engine recently, which will be the main force for commercial launches in the future."

"So, don't worry, Director Chen, there is still work behind your factory!"

As an engine manufacturing unit under the Rocket Research Institute, Factory 112 relies almost entirely on the Rocket Research Institute for food. The Rocket Research Institute can give them more manufacturing tasks, and they can also have more food.

Although the country has vigorously promoted the reform of state-owned enterprises in the past two years, pushing them to the market.

However, it is still too difficult for a unit like 112 to face civilian customers.

After all, it is hard to imagine what a private person or a private company would want a rocket engine for? !

And as a component of some kind of big killer, rocket engines are actually very difficult to export.

Even after 20 or 30 years, the countries in the world that can assemble and build their own rockets can count on both hands.

So why do other people import this thing?

Clearly tell others that we develop our own missiles?

Then wait for Eagle Sauce's iron fist.

However, according to the current international pursuit of low-cost rocket launches, as long as the Rocket Research Institute maintains successful launches, there will be no more accidents like the last time.

Next, there must be a steady stream of orders, especially the new rocket that will be applied with a new generation of liquid oxygen kerosene engine.

It is even more able to reduce the cost to the extent that others will not believe it.

"Dean Chen, the good days of Factory 112 are yet to come!"

Walking out of the workshop, Zhang Xingyang stretched his arms and said.

Although I can't let other people in the country profit with me for the time being, at least it's great that people in the aerospace system can live better!

Looking at the youthful Zhang Xingyang, Chen Chunming felt that he seemed to be much younger.

Trot followed, and asked:

"Dean Zhang, when can we give more manufacturing tasks for Factory 112?"
