Yang Weining saw through Lu Yang and Chen Liangwei's thoughts, and said with a smile: "Uncle Chen, this CATIA system is Dassault's housekeeping skill, and now it is only rented and not sold, and the annual rent of software alone is more than 200,000 US dollars, not counting the hardware cost of hundreds of thousands of US dollars, is our budget enough? And even if the budget is sufficient, when we complete the negotiations with the French, and then introduce this system into China, and complete personnel training, it will have to wait until the year after tomorrow, and the J-7III project will not be able to wait that long."

The flame of hope that had just risen in Chen Liangwei and Lu Yang's hearts was suddenly extinguished by Yang Weining's basin of cold water.

Chen Liangwei frowned and said, "Wei Ning, what do you mean when you just said that you can help us solve the problem?"

Yang Weining smiled: "I mean, why don't we develop a CAD system ourselves?"

"Do it yourself?"

Chen Liangwei and Lu Yang were stunned.

Yang Weining said: "Uncle Lu, Uncle Chen, the significance of CAD technology to the promotion of the aviation industry must be clear to you, if we do not take this opportunity to develop our own CAD software, we will only be pulled further and further away by other countries, it is better to take advantage of the current CAD technology in various countries has just begun to develop not long ago, and catch up." Nowadays, the price of CAD technology is extremely expensive, the degree of commoditization of software is very low, the developers themselves are large users of CAD, and the technology is kept secret from each other, and only a few arms dealers who are financially supported by the state have the conditions to independently develop CAD technology. In the United States, for example, CADAM is supported by Lochheed, CALMA is developed by General Electric (GE), CV is supported by Boeing, I-DEAS is supported by NASA, UG is developed by McDonnell Douglas (MD), and even CATIA is developed by Dassault of France. If we can develop our own CAD software, it will inevitably become an important driving force for China's aviation industry. ”

Lu Yang said: "Wei Ning, we don't understand this truth, the problem is that the domestic research on CAD technology is still in the early stage of exploration, and there are few who really understand this, even if we really set up a project team to develop, where does the funding come from? Where does the talent come from? When will the development be completed?"

Yang Weining smiled slightly, pointed to himself, and said: "Knowledgeable talent, don't you just stand in front of you?" I have done in-depth research on CAD technology during my graduate school, and I have subscribed to many related English journals through my father, and I have been keeping track of the latest foreign technology. I'm confident that if I am given a small computer, I will be able to give you a software equivalent to CADAM in a month, and in a year, I will be able to make this software have both surface modeling and 3D wireframe design and drawing functions. ”

Lu Yang glared and said, "Wei Ning, when is this, you are still joking with Uncle Lu." ”

Lu Yang really loves and hates Yang Wei, although this kid loves to brag, but the previous conversation has proved that this kid does have goods in his stomach, and Lu Yang's attitude towards him has changed back.

Chen Liangwei also said: "Wei Ning, listening to your analysis of the CAD industry tonight, your Uncle Lu and I have indeed benefited a lot, but this CAD software development is not a small project, don't talk big." ”

Yang Weining said with a straight face: "Uncle Lu, Uncle Chen, I didn't say anything big. Otherwise, I'll make a military order and give me a month, and if I can't come up with a software that is comparable to CADAM, I'll be fired. ”

Lu Yang and Chen Liangwei were intimidated by Yang Weining's momentum, and they were speechless for a while.

After a long while, Lu Yang said, "Wei Ning, you can't talk nonsense. ”

Yang Weining said: "Uncle Lu, I guess you also know my character more or less from my father, I came to Rongfei after a lot of hard work, do you think I look like a person who jokes about his future? What's more, this kind of thing doesn't need to pay much cost at all, as long as you give me a small computer, you can see the results in a month." ”

Lu Yang and Chen Liangwei couldn't help but look at each other, and Lu Yang said, "Are you really sure?"

Yang Weining said: "Uncle Lu, if I say that in the field of CAD, if I consider myself second, no one in China dares to recognize the first, do you believe it?"

Lu Yang and Chen Liangwei were speechless again, the Chinese pay attention to humility and low-key, in this era, they have really never seen such an arrogant person as Yang Weining.

Chen Liangwei hesitated, looked at Lu Yang and said, "Old Lu, why don't we let Xiao Yang try?"

Lu Yang pondered for a moment and said: "Wei Ning, to be honest, your Uncle Chen and I are very willing to believe in you, but this matter is not so easy to succeed, now the computer resources in the institute are very tight, if you want to vacate a small computer for your use, you must be collectively studied and approved by the party committee of the research institute, you are just a recent college graduate, how can you convince the members of the party committee to believe you?"

Yang Weining said with a smile: "Uncle Lu, you just need to submit this proposal, it's a big deal for me to beg my father, his face should be enough for a month's right to use the minicomputer." ”

"You kid!"

Lu Yang pointed at Yang Weining, and couldn't help crying and laughing.

However, Yang Weining's words deepened his trust in Yang Weining.

Although this kid looks a little arrogant, he really has goods in his stomach, and he does not stick to rules and regulations, unlike the kind of person who does not know the depths, if he can really make a domestic CAD software, it is really a great thing for Huaxia's aviation industry.

"Okay, Wei Ning, this matter will be brought up to you by Uncle Lu as a guarantee, but whether you can pass it or not depends on yourself. ”

"Don't worry, Uncle Lu, I won't let you down. ”

……

After leaving Lu Yang's house and returning to his nest, it was already more than ten o'clock in the evening.

However, Yang Weining didn't feel sleepy at all, he didn't expect that on the first day he came to the 611 Institute, he seized an opportunity to change history.

The history of the development of China's CAD technology is clear to Yang Weining.

In normal history, it was not until October 1984 that Shenyang Aircraft Industry Company and others organized a delegation to the United States again to complete the negotiation and introduction of CADAM software.

In 1987, Nanchang Aircraft Company introduced UG software with curved surface modeling and three-dimensional wireframe design and drawing functions from the United States, and designed and produced P-5 agricultural aircraft and K-8 intermediate training aircraft through this software.
