The story behind the successful launch of the Long March series of launch vehicles

The story still needs to start with an award won by Jiangsu Beiren a month ago.
 

I remember when I first came, Mr. Lin told me: "Pony, you are also a big project manager." I said: "What is a big project manager?" "There is a project investment of nearly 10 million, which needs us Work with customers to complete the research and development of intelligent welding equipment and processes for the Long March rocket storage tank..."
 

To be honest, I was also the first time to do this kind of national project with an investment of 10 million. At that time, I was 33 years old, and the other members were all in my 20s. The team as a whole was relatively young, and I didn’t have much experience in the project. It is deceptive to say that there is no psychological pressure.
 

Everything is difficult at first, then I adjusted my mind, stepped down and determined what the goal of this project is? What core technical points are included in this big goal? Break down the big goals into small achievable goals, and then break down to match the team members’ related abilities. If problems are encountered, we can solve them internally, and seek external resources to solve them if we cannot.
 

At that time, the biggest feeling of doing this project was that the rocket was not the same as the car. Its technical requirements were very high. If there was a problem with the car, it could be driven to a repair shop for repairs. If the rocket launch failed, the loss would be immeasurable. of.
 

The launch vehicle has a diameter of three meters, and the cost of this part is very high, so we take the "single-point technical verification-test board-test part-simulation part-actual product" Process to verify step by step, each process needs to reach 100% completion before entering the next stage.
 

The "sample" mentioned above is the "test piece". At that time, I got the newly welded test piece. From the appearance, the effect is really good. I wanted to share it with the team members. The test piece was almost one person tall and was a curved board. At that time, I was just holding my chest, and I couldn’t see the road ahead. When I stepped down the stairs, I accidentally fell a bit. Small scars, but now I think of this thing, I really feel a happy feeling, did not think this pain is a bad memory, but remembered that joy.
