Chapter 202

Turning on a Swedish original two cylinder gasoline engine, Ding laixiang didn't immediately go to see it. Instead, he said to a middle-aged man around him, "Xiaoqian, you are an expert in this field. You'd better come and see."

Zhuang Jianye, a middle-aged man, also knows that Qian Qiang is one of the large-scale school run factories of Western Airlines, chief engineer of machinery manufacturing factory of Western Airlines, and professor of power department of Western Airlines.

The domestic 18 kW double cylinder gasoline engine used by Tengfei factory before was provided by Xihang machinery factory.

Now h Airlines suddenly abandoned domestic power and switched to Swedish products. To tell you the truth, the impact on Tengfei factory is really not very big. It's the Western Airlines Machinery Factory that breaks the bones and muscles.

So when Zhuang Jianye told Ding laixiang about it, not to mention the machinery factory of China Western Airlines, but the University of China Western Airlines was shocked. We should know that the University of China Western Airlines is short of funds every year. There is no extra money except for the scientific research funds.

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

By providing gasoline engines for UAVs to take-off factory, Xi'an Aviation Machinery Factory is one of the best run factories of Xi'an University of Aeronautics and Astronautics. If Xi'an aviation machinery factory goes wrong, it will not affect one factory, but the welfare of the whole school staff.

So the vice principal in charge of logistics immediately sent Qian Qiang to see what happened.

Qian Qiang is of medium build, with thick eyebrows and big eyes. He looks a little rough, which is quite different from the image of the intellectual in his imagination. However, he is a very serious and cautious person. He doesn't speak much at ordinary times. He almost devotes all his energy to scientific research and academic research.

Otherwise, he would not become a professor in his early 40s and the chief engineer of a school run factory.

So when Ding laixiang said that, Qian Qiang didn't refuse. He asked the students behind him to lift the Swedish engine to the table next to him. Then he made a preliminary measurement with the measuring instrument brought by Western Airlines. His originally unsmiling face became more dignified.

Ding laixiang couldn't help asking: "how about Xiaoqian? Can we do it? "

Qian Qiang shook his head and looked very disappointed: "the Swedish engine is not only more powerful than ours, but also lighter than ours. We have to take back the specific technical parameters for careful analysis, but one thing is certain that we can't make such a delicate engine with our current technological level."

When Ding laixiang heard that Yan's face was not very good-looking, he still held his hope and asked, "can't we do anything about it?"

Qian Qiang sighed: "it's very difficult at this stage. I haven't got a deep understanding of the details, but from the preliminary observation, the Swedish engine adopts many new technologies that we don't have. Let's not say anything else. Look at its oil pipeline."

Then Qian Qiang pointed to a few bent pipes. Zhuang Jianye and Ding laixiang hurriedly went to see them. Qian Qiang pointed to several smooth joints and said, "we can't do their pipeline welding process."

"What craft?" Ding laixiang asked.

"Vacuum brazing!" Qian Qiang blurted out.

"Vacuum brazing? Professor Qian, are you sure it's vacuum brazing As a result, as soon as Qian Qiang's words were exported, Zhuang Jianye opened his eyes and asked in surprise. Without thinking about what Zhuang Jianye would as like as two peas,

Qian Qiang did not hesitate to think, "yes, I should have seen it. I visited the west side in Germany last year and saw this kind of welding technology in situ. It is exactly the same process as the oil circuit on this engine."

"Well This kind of craft is so important that Western Airlines didn't want to do it by itself? " Zhuang Jianye continued to ask.

Qian Qiang said with regret: "the school also wants to do it, but it's a pity that the funds are insufficient. It's good to ensure the normal operation of several aerospace projects. For such mechanical projects, the school doesn't have the heart to consider them."

"Xiaozhuang, you have asked so many questions. Is there a vacuum brazing device in your Tengfei factory?" Before Qian Qiang's voice fell, Ding laixiang asked Zhuang Jianye.

Qian Qiang is not very familiar with Zhuang Jianye, but Ding laixiang knows too much about this wicked ruffian who is immoral and smoking.

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

At first, Ding laixiang didn't feel anything. Later, he gradually found something wrong, but he didn't stop it, because there were many kinds of UAVs tested by Zhuang Jianye, many of which were not approved but he wanted to be included in the research.

As a result, Ding laixiang scolded Zhuang Jianye for being shameless, so he turned a blind eye to let Zhuang Jianye go through all kinds of twists and turns, which is not to say that he would occasionally use the data for comparative analysis, enrich his research results, and charge some interest on Zhuang Jianye's scientific research resources.

So listen to Zhuang Jianye very surprised asked two questions, Ding laixiang will know that this boy has goods.

Just as Ding laixiang is familiar with Zhuang Jianye, Zhuang Jianye also knows the old professor. When he hears this question, he knows that he can't hide it. However, he is not ready to hide it, so he nods his head and admits it. Before he can explain, Qian Qiang's eyes are wide open in surprise: "director Zhuang, does your factory really have vacuum brazing equipment?""We don't have one, but Yonghong has one. It's a coincidence..." Zhuang Jianye told the two professors about his first research project when he was in Yonghong factory in order to evaluate his professional title. Then he said, "I retired because of some things, but Lin Guanghua followed up for more than half a year, and finally made a finished product. The effect was not bad. It was just that the volume was a little small, and too large parts could not be welded However, there is no problem with the welding of the oil circuit of this five kilogram two cylinder gasoline engine. "

"Can we transfer the vacuum brazing furnace from Yonghong factory to Xihang machinery factory?" Ding laixiang asked directly after listening.

Zhuang Jianye frowned and thought, "it's not a big problem, but after all, things belong to Yonghong factory, so..."

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

"You see what you said. It's useless for Yonghong factory to do it anyway. It's up to me." When he heard that Ding laixiang had another wind tunnel test to rub against, Zhuang Jianye didn't even want to think about it. His chest was pounding so hard that he could build his own engine, which was better than eating ash in Yonghong factory.

Ding laixiang nodded with satisfaction. He looked like a child. But before he laughed twice, he saw Qian Qiang's constipation on his face. He frowned and whispered several times. Then he turned around and almost made Zhuang Jianye fall down: "if it's possible, the electron beam welding machine and the high-speed water pressure cutting machine will also help to get it, I'll be happy We guarantee that the Swedish engine will be copied in three months
