Turning on a Swedish original twin-cylinder gasoline engine, Ding Laixiang did not immediately go forward to see it, but said to a middle-aged man next to him: "Xiaoqian, you are an expert in this area, or you should come and see." ”

Zhuang Jianye, a middle-aged man, also knows Qian Qiang, one of the larger school-run factories of Xi'an Airlines, the chief engineer of Xi'an Airlines Machinery Manufacturing Factory, and a professor of the aviation power department of Xi'an Airlines.

The domestic 18 kilowatt twin-cylinder gasoline engine used by Tengfei Factory was provided by Xihang Machinery Factory.

Now H Airlines suddenly abandoned domestic power and switched to Swedish products, to be honest, the impact on the Tengfei factory is really not very big, and the West Airlines Machinery Factory is called a broken muscle.

Therefore, when Zhuang Jianye told Ding Laixiang about the matter, not to mention the Xihang Machinery Factory, even the Xihang University behind it was shocked, you must know that the annual funds of Xihang University can be described as stretched, and there is no extra money except for scientific research funds.

If there are not a few school-run factories to maintain, the teachers and staff of Western Airlines may not even be able to pay basic benefits.

Xihang Machinery Factory relies on providing gasoline engines for drones to Tengfei Factory, which is one of the best school-run factories under Xihang University.

So after receiving the news, the vice principal in charge of logistics immediately sent Qian Qiang over to see what the situation was.

Qian Qiang is of medium stature, with thick eyebrows and big eyes, and looks a little rough, which is very different from the image of an imaginary intellectual with a polite and polite quality, but he is an extremely serious and cautious person, and he usually doesn't talk much, and almost all his energy is devoted to scientific research and academics.

Otherwise, he would not have become a full-fledged professor in his early forties and the chief engineer of a school-run factory.

So as soon as Ding Laixiang said it, Qian Qiang did not shirk, and asked the students behind him to lift the Swedish engine to the table next to him, and then used the measuring instrument brought from Xihang to make a preliminary measurement, and the originally unsmiling face became more dignified.

Ding Laixiang couldn't help but ask: "Xiaoqian, how about it? Can we make it?"

Qian Qiang shook his head, looking very disappointed: "Sweden's engine is not only more powerful than ours, but also lighter than ours, and the specific technical parameters have to be taken back for careful analysis, but one thing is certain, with our current level of technology, we can't make such a delicate engine." ”

Ding Laixiang's face was also a little unpleasant when he heard this, but he still asked with hope: "Don't we have anything to do?"

Qian Qiang sighed: "It is difficult at this stage, I haven't had an in-depth understanding of the specifics, but from the preliminary observation, the Swedish engine adopts a lot of new processes that we don't have, not to mention anything else, you look at its oil pipeline." ”

Saying that, Qian Qiang pointed to a few bent pipes, Zhuang Jianye and Ding Laixiang hurriedly went to look, Qian Qiang pointed to a few smooth joints and said: "Their pipeline welding process, our factory can't do it." ”

"What process?" Ding Laixiang asked.

"Vacuum brazing!" Qian Qiang blurted out.

"Vacuum brazing, Professor Qian, are you sure it's vacuum brazing?" As soon as Qian Qiang's words came out, Zhuang Jianye's eyes widened and he asked in surprise.

Qian Qiang didn't know why Zhuang Jianye reacted like this, but he still nodded without thinking: "It should be true, when I visited West Germany last year, I saw the field operation of this welding process, which is exactly the same as the oil connection on this engine, and it is obvious that the same process is used." ”

"Uh...... This kind of craftsmanship is so important, Xihang didn't think about making a set of it yourself?" Zhuang Jianye continued to ask.

Qian Qiang regretted when he heard this: "The school also wants to get it, but unfortunately the funds are insufficient, and it is good to be able to ensure the normal operation of several aerospace projects. ”

"Xiaozhuang, you have asked so much, is it possible that your Tengfei Factory has a vacuum brazing device?" Before Qian Qiang's words fell, Ding Laixiang opened his mouth and asked Zhuang Jianye.

Qian Qiang is not very familiar with Zhuang Jianye, but Ding Laixiang knows too well about this bad ruffian who lacks virtue and smokes.

With a few models, he began to blatantly hang the drones in the factory under his scientific research projects, and then began to rub various wind tunnel test opportunities.

At first, Ding Laixiang didn't feel anything, but then he gradually found that something was wrong, but he didn't stop it, because there are many types of airfoils in the drones tested by Zhuang Jianye, and many of them are the ones he wanted to include in the research topic but were not approved.

So Ding Laixiang scolded Zhuang Jianye for being shameless in his heart, so he turned a blind eye to Zhuang Jianye to all kinds of tosses, not counting the occasional data for comparative analysis, enriching his own research results, and collecting some interest on Zhuang Jianye's scientific research resources.

So after hearing Zhuang Jianye ask two questions in surprise, Ding Laixiang knew that this kid had the goods in his hands.

Just as Ding Laixiang was familiar with Zhuang Jianye, Zhuang Jianye also knew this old professor, as soon as he heard such a question, he knew that he couldn't hide it, but he wasn't ready to hide it, so he nodded and admitted it, but before he could explain, Qian Qiang's eyes widened in surprise: "Director Zhuang, does your factory really have vacuum brazing equipment?"

"Our factory doesn't have it, but Yonghong factory does, and it's ......a coincidence," Zhuang Jianye said, and told the two professors about the first research project done in Yonghong Factory when he was in Yonghong Factory, in order to evaluate the title, and then said: "I quit because of some things, but Lin Guanghua and a few of them followed up for more than half a year, and finally made a finished product, the effect is not bad, but the volume is a little smaller, and the parts that are too large can not be welded, but the oil circuit welding of the double-cylinder gasoline engine of about five kilograms is still no problem." ”

"Say so much, can the vacuum brazing furnace of Yonghong Factory be transferred to our Xihang Machinery Factory?" Ding Laixiang asked directly after hearing this.

Zhuang Jianye frowned and thought about it: "It's not a big problem, but after all, the thing is something from Yonghong Factory, so it's ......."

"I applied for two more wind tunnel test projects not long ago, and I wanted to discuss the experimental model with you......

"Look at what you said, what a big deal, anyway, it's useless for Yonghong Factory to do it, this matter is on me. As soon as he heard that Ding Laixiang had another wind tunnel test to rub, Zhuang Jianye didn't want to think about it, his chest was pounding, and it was better to build an engine for himself than to stay in Yonghong Factory and eat ashes.

When Ding Laixiang heard this, he nodded with satisfaction, looking like a teachable child, but before he could laugh twice, he saw Qian Qiang's constipated face, so he frowned and leaned over and whispered a few times, and then turned around and almost made Zhuang Jianye fall down with a word: "If you can, the electron beam welding machine and the high-speed hydraulic cutting machine will also help you get it, and we guarantee that the Swedish engine can be copied within three months." ”
