A big country of aerospace with black technology

The development of the new engine has entered a smooth transition period, and Zhang Xingyang has broken down the work of structural design and handed it over to various departments.

The development of new materials relies on the equipment and technology of the research institute itself, and there is no way to continue to improve.

Therefore, Zhang Xingyang began to turn his attention to the accident summary of the failure of the last rocket launch.

Zhang Xingyang knew very well that the last time the rocket failed, the technical reason was naturally a problem with the rocket's attitude control system.

Specifically, one of the chip pins in the control system had a weak soldering. As a result, after the rocket was started, the chip issued a wrong control command.

The rocket's central control system mistakenly believed that the angle of the rocket was tilted, and thus began to automatically return to normal.

The result was that the rocket crashed crookedly into the hill next to the launch site.

However, behind this incident, it is far from being so simple. It actually reflects a problem with the management system of the rocket system.

The prior inspection was sloppy, and there were even cases where unqualified valves were sent back as repaired parts.

If you want to prevent such accidents in the future rocket manufacturing and launching process, you must establish a perfect system!

Zhang Xingyang felt it was necessary and proposed a double regulation and zero system for the aerospace system.

This is the guarantee system that Dragon Kingdom has explored by itself in its original history.

Now Zhang Xingyang just took them out in advance.

The so-called double regulation and zero system is divided into five principles of technical zeroing and five principles of management zeroing.

In fact, when Zhang Xingyang was there, there was a stricter quality assurance system than this, but it required very high technical level and high-quality industrial workers.

This era does not have these conditions, and without the soil for realization, rashly using a system that transcends the times will only cause more serious consequences than it is now.

Technical zeroing is to technically eliminate possible problems in the entire system engineering.

For example: if there is a problem with the rocket engine during the test, it is necessary to find out the specific component that caused the problem, and it is necessary to find out the root cause of the problem. And this problem can be theoretically analyzed through experiments or other methods, so as to make timely and feasible corrections to the generated problems and ensure the solution of the problems. And feed back the quality problems encountered in this process to this model, this unit and other units.

Of course, the system cannot be established by relying only on a piece of paper, and the entire process needs to be managed reasonably.

Zhang Xingyang came to the control system research room of the research institute, which is the department responsible for the research of the entire rocket control system.

Of course, the researchers in the original laboratory have almost left now, and there are only three or two big cats and kittens left.

Zhang Xingyang gathered everyone who was busy reviewing the previous control system and held an internal meeting.

He decided that the implementation of the double-return-to-zero system should start from the control system research room.

"I know that everyone feels a lot of guilt about the last rocket accident." Zhang Xingyang glanced at the unhappy faces of everyone present, and continued:

"During this accident, several of our colleagues, friends or relatives left us."

"But life has to go on. The country's aerospace industry still needs us to shine. The only thing we can do for them is to do our best to find out the cause of the accident, so as to prevent these problems in the next launch."

"Only in this way can they comfort their spirits in heaven!"

Everyone present was a little surprised at what Zhang Xingyang just said. As the acting dean, he did not find the responsibility of the control system research room, but comforted everyone and asked everyone to find out technical problems for those who died in the accident. question.

This pattern, this courage is not something that other people can have.

"Now in the research room, do you have any ideas on the possible causes of the rocket's attitude problem?" As a technical master, Zhang Xingyang is more concerned about specific technical issues.

A thin, dark and dry boy wearing a pair of big black-rimmed glasses, who seemed to be blown down by a gust of wind, stood up and said with some embarrassment:

"Because when the accident happened, the violent explosion destroyed almost everything, and it was difficult to analyze the accident problem."

Zhang Xingyang knew that he, Qin Ming, a high-achieving student who had just graduated from the University of Electronic Science and Technology of China a few years ago, would become a master in rocket control systems in the future.

But he is still just a newcomer who has just begun to get in touch with the rocket control system.

"I know there are problems in this area. It is more troublesome to investigate without the entity of the accident."

Zhang Xingyang did not ignore Qin Ming's complaints, but gave his own solution, which was to implement the technology zeroing system in advance.

"We must fully consider any possible problems in the system, and reproduce them one by one! Until the key points of the problem are found, then we can solve it!"

Hearing Zhang Xingyang's rhetoric, everyone present showed embarrassment. At present, many people in the control system research room have left, and now there are only a dozen people left. Go to the year of the monkey and the month of the horse.

Without waiting for others to bring it up, Zhang Xingyang, who has been in charge of various super-large space projects all year round, saw everyone's concerns at a glance, and said:

"I will solve the problem of manpower. You first make a project plan for the tests that need to be carried out on each component."

Everyone was a little surprised when they heard this. Zhang Xingyang, as a fresh graduate, handles various matters as if he has worked in a scientific research unit for many years.

Before people like me said anything, Zhang Xingyang had already resolved everyone's concerns.

Now that Zhang Xingyang has said so, Qin Ming, as the representative of everyone, has nothing to worry about, and said:

"Dean Zhang, we will make a project plan as soon as possible, but you still need to arrange the manpower as soon as possible, otherwise, even if we make a plan, it may be difficult to carry out quickly."

Zhang Xingyang nodded and said: "Don't worry about the manpower, but you must firmly remember the principle of zero technology. If you do something that is not in place, don't blame me for being unkind!"

Everyone looked at Zhang Xingyang, who was sitting on the top, showing a faint sternness, and felt that the other party attached great importance to the construction of the new system.

The technology zeroing system is considered to be the beginning of development. Although I don't know what it will look like, Zhang Xingyang is not particularly worried.

This system can be used for decades later, so it naturally has its advantages.
