The development of new engines has entered a smooth transition period, and Zhang Xingyang has broken down the structural design work and handed it over to various departments.
The development of new materials relies on the institute's own equipment and technology, and there is no way to continue to improve.
As a result, Zhang Xingyang began to shift his attention to the accident summary of the last rocket launch failure.
Zhang Xingyang knew very well that the technical reason for the failure of the last rocket launch was naturally a problem with the rocket's attitude control system.
Specifically, a chip pin in the control system had a weak solder. As a result, after the rocket started, the chip issued an incorrect control command.
The rocket's central control system mistakenly believed that the angle of the rocket was tilted, and began to automatically return to normal.
The result was that the rocket hit the hill next to the launch site crookedly.
However, behind this incident, it is far from that simple. It actually reflects a problem with the rocket system's management system.
The pre-inspection was careless, and there were even cases where unqualified valves were sent back as repaired parts.
If we want to prevent such accidents in future rocket manufacturing and launch processes, we must establish a complete system!
Zhang Xingyang felt it was necessary and proposed a dual-regulation zero system for the aerospace system.
This is the security system that the Dragon Kingdom explored on its own in its original history.
Now Zhang Xingyang just took them out in advance.
The so-called double-regulation 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 more rigorous quality assurance system, but it required a very high technical level and extremely high-quality industrial workers.
This era does not have these conditions, and the soil for realization has been lost. Rushing to use a system that transcends the times will only cause more serious consequences than now.
Technical zeroing is to technically eliminate possible problems that may arise in the entire system engineering.
For example: If a problem occurs with the rocket engine during the test, then the specific component that caused the problem must be found, and the root cause of the problem must be found. And this problem can be theoretically analyzed through experiments or other methods, so that the problems can be corrected in a timely and feasible manner to ensure the solution of the problem. And feedback the quality problems encountered during this process to this model, this unit and other units.
Of course, the system cannot be established by just relying on a piece of paper. The entire process needs to be properly managed.
Zhang Xingyang came to the control system research room of the institute, which is the department responsible for researching the entire rocket control system.
Of course, most of the researchers in the original laboratory have now left, leaving only three or two big cats and kittens.
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 would start in the control system research laboratory.
"I know that everyone feels very guilty about the last rocket accident." Zhang Xingyang glanced at the unhappy faces of everyone present and continued:
"In this accident, several of our colleagues, friends or relatives left us."
"But life must go on, and the country's aerospace industry still needs us to shine. The only thing we can do for them at the moment is to do our best to find out the cause of the accident so as to eliminate these problems during the next launch."
"Only in this way can their spirits in heaven be soothed!"
Everyone present was a little surprised by what Zhang Xingyang just said. As the acting dean, he did not find the control system laboratory responsible. Instead, he comforted everyone and asked everyone to find technical solutions for those who died in the accident. question.
This pattern and this courage cannot be possessed by others.
"Now in the research room, do you have any ideas about the possible causes of the rocket attitude problem?" Zhang Xingyang, as a technical master, is more concerned about specific technical issues.
A thin, dark-skinned boy wearing a pair of big black-rimmed glasses, who looked like he could be blown over by a gust of wind, stood up and said with some embarrassment:
"Because when the accident occurred, a violent explosion destroyed almost everything, making it difficult to analyze the accident problem."
Zhang Xingyang knew that he, Qin Ming, a top 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.
However, he is still just a newbie who has just started to have full contact with the rocket control system.
"I know there are problems in this area. It is more troublesome to investigate when there is no accident entity."
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 we find the key points of the problem, and then solve it!"
Hearing Zhang Xingyang's heroic words, everyone present looked embarrassed. Currently, many people have left the control system research laboratory, and now there are only a dozen or so people left. If you want to rely on this manpower to complete the accident recurrence investigation, you don't know what to investigate. Go to the year of the monkey and the month of the horse.
Before anyone else could bring it up, Zhang Xingyang, as someone who has presided over various large-scale space projects all year round, saw everyone's concerns at a glance and said:
"I will solve the manpower problem. 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. As a newly graduated student, Zhang Xingyang handled various matters as if he had worked in a scientific research unit for many years.
Before people like him said anything, Zhang Xingyang had already solved everyone's concerns.
Now that Zhang Xingyang said so, Qin Ming, as the representative of everyone, had nothing to worry about and said:
"Dean Zhang, we will make a project plan as soon as possible, but you still have to arrange the manpower as soon as possible. Otherwise, even if we make a plan, it will be difficult to carry out quickly."
Zhang Xingyang nodded and said: "Don't worry about the manpower, but you must keep in mind the technical zeroing principles. If there is anything you don't do well, don't blame me for being unkind!"
Everyone looked at Zhang Xingyang, who was sitting on top and showed a faint stern air, and felt that he attached great importance to the construction of the new system.
The technology zeroing system has begun to develop. Although he doesn't know what it will grow into, Zhang Xingyang is not particularly worried.
This system can be used for decades in the future, which naturally has its advantages.
