703 schools.

The semi-dead research institutes have gained a lot of popularity this year. After cooperating with Beifeng Company, they received an amount of 80 million research funds last year, and in early January this year, they increased by 240 million yuan.

Don’t think that this money is a lot. The research funding for heavy-duty gas turbines is basically used in units of 100 million and 100 million.

For example, General Electric invested 200 million meters in 2008 to build the world's largest full-speed no-load test bench in South Carolina.

Similar investments, such as General Electric, Siemens, Mitsubishi, etc., have been continuously investing in these decades.

The investment of those domestic research institutes and enterprises each year is not enough for others, so a lot of houses have been built.

Therefore, the 320 million investment by Beifeng Company is nothing.

The main factory of Beifeng Company is located in Bingcheng, close to the 703 Research Institute.

Chen Xuedong, chief engineer of the 703 Research Institute, and more than a dozen engineers from Beifeng Company, as well as engineers from Snail Steel are discussing how to improve a heavy-duty gas turbine.

Dong Xincheng, an engineer at Snail Steel, shook his head after reading the test data: "No, it's still not possible. To improve performance, you can only increase the combustion temperature and gas pressure. The problem is that your materials cannot support it."

Chen Xuedong also looked helpless: "We have already adopted Baosteel's latest high-performance steel unless imported high-temperature resistant materials."

"No, it seems that our factory still needs to take action."

"Uh? Your company's silicon nano-plating is indeed very powerful, but under ultra-high temperature operation, the service life is only a few months. You can't stop the machine every few months before electroplating, right?" Chen Xuedong immediately objected.

The 703 Institute had tried using silicon nanoplating before, and the effect was very good at the beginning. After testing for a period of time, the blades of the gas turbine deformed rapidly.

After disassembly and checking, it was found that the silicon nanoplating was damaged by high temperature.

Dong Xincheng shook his head: "It's not silicon nano-plating, and our company doesn't have only one material. I'll call to ask about the situation."

After saying that, he ignored the confused people and went to the office to make a phone call.

Snail Steel, a subsidiary of Snail Industry, has the most luxurious alloy research institute in the world. The reason why it is said to be the most luxurious is that there are a large number of nanomaterials that ordinary companies do not have.

Nano-pure iron powder and nano-pure aluminum powder are all small meanings, such as nanotungsten powder, nanobismuth powder, etc., which are also common.

There are also some raw materials that are pitifully rare in the world, such as nano rare earth elements and nanorhenium powder, which are rare on the market.

He Wen, who was transferred from the headquarters of the Shanmei Research Department, is the chief technology executive of Snail Industry and also serves as the director of the Alloy Research Institute.

He Wen, who had just come out of the laboratory, took the call from his assistant.

"Hey, Xincheng, what's going on over there?"

"Don't mention, Baosteel's steel still does not meet the requirements, but in terms of system design, it is difficult in a short period of time."

He Wen's heart is like Mingjing. The overall performance of industrial products often depends on two factors, namely materials and design.

Materials are the foundation, and design is just the icing on the cake.

Just like the N20 high-energy material developed by their company, the material performance has increased, and the performance of the launch vehicle is directly explosive.

If N20 is not available, even if it is designed with a scattered nature, the performance will not change qualitatively based on the original fuel.

Therefore, domestic gas turbines need to develop greatly, and at this stage, they should focus on materials.

"You want to ask, our company's high-temperature resistant materials!"

"Yes, Mr. He, how is the high-temperature resistant alloy in our company now?"

He Wen smiled and said, "If you were half a month earlier, I wouldn't have answered. A week ago, our rhenium-tungsten alloy steel had already determined two preliminary formulas, one of which can be mass-produced and can withstand the ultimate temperature of 2137 degrees Celsius."

"How difficult is processing?" Dong Xincheng asked this because the hardness of tungsten steel is extremely hard and is very unfriendly to processing.

"It's OK, the hardness of this formula is not too high. We can use powder metallurgy to create a rough embryo, and then perform deep processing to consume at most some cutting heads."

"Then I send the parts I need and make a batch of them to try."

"no problem."

Half an hour later, through the internal network of Time Information, Beifeng Factory sent a batch of spare parts design drawings that required high-temperature resistant materials to Cangzhou Snail Steel Factory.

Beifeng Factory's industrial software is an industrial software that uses Time Information, which is basically the same as the Snail Industry. Therefore, as soon as their design drawings come over, they can enter the production workshop for production.

Powder metallurgy workshop of steel plant.

The technician chose a recipe and then pressed the switch.

The workshop’s automation system controls the equipment and generates high-temperature resistant alloys bit by bit, and powder metallurgy is a fine job.

At the same time, dozens of blades are being generated. The technicians check the generation from time to time. After more than three hours of continuous operation, the first batch of blades in the powder metallurgy workshop were freshly released.

He Wen picked up one of them. This was still a relatively rough embryo storage piece. It needed further deep processing to become a qualified product.

Soon several technicians sent the blades to the deep processing workshop.

After preliminary processing of CNC machine tools, the blades can be used, but the technicians did not stop.

The snail industry has a very special deep processing technology, which is a nano-scale processing technology developed based on six-cone ball oxygen.

After a series of inspections, such as lattice, internal cracks, etc., if there is any problem, the part can only be scrapped.

Finally, enter the nanoprocessing workshop.

Several technicians looked at the design drawing parameters on the computer. After laser scanning, the actual size of the parts and the design drawing parameters must be consistent. If there is no consistent position, the system will automatically mark it.

The workshop team leader ordered: "Start the processing!"

The surface of a blade is 3.73 microns thicker than the design parameters. It is specially customized surface etching machine, which is closely attached to the surface of the blade.

“Sealing is normal.”

"Inject etching liquid."

"Power on for two seconds."

After two seconds, the etching head leaves the blade surface.

There is a corroded damage layer on the surface, where the tungsten element has been stripped, and the grinding head of the robot arm is attached to that surface, and it is quickly ground for a few seconds, and then surface cleaning is performed.

By repeating this set of processes continuously, the dimensional accuracy of the blades basically reaches 10±nm to be considered a qualified product.

Such a part starts with powder metallurgy and undergoes rough processing and nanofinishing. It takes about a week to complete the processing of a part.

It took Snail Steel more than a month to process the spare parts of this set of gas turbine. This set represents the world's most sophisticated spare parts before it was transported from Cangzhou to Bingcheng.

Not long after the Spring Festival, several large trucks from Beifeng Factory in Bingcheng delivered this expensive spare parts here.

After obtaining these parts, Chen Xuedong, Dong Xincheng and others immediately organized engineers to start assembling a new generation of gas turbine engines.
