The specimen was pulled off by a huge force, and the entire laboratory fell into silence, absolute silence, and it took a long time for everyone to come back to their senses and accept this fact.

Sun Xiaoping said: "Boss, if you don't see it with your own eyes, you can't imagine it!" ”

Zeng Qinghai said: "Yes, boss, with this new material, not to mention an engine with a thrust-to-weight ratio of 15, or an engine with a thrust-to-weight ratio of 20, we can also develop it." ”

Li Tianfeng nodded, and Li Tianfeng said: "This material is very good and has a wide range of uses, but it is not without shortcomings. ”

"Oh." The three of them looked at Li Tianfeng one after another, and Sun Xiaoping even said, "Boss, what are the shortcomings of this material?" ”

Li Tianfeng said: "This material is not resistant to high temperatures, and the maximum temperature resistance is 450 degrees, which can only be used for normal temperature parts, such as fans of our engines, compressor parts, and cannot be used for hot end parts, such as combustion chambers, turbines and other components." ”

There is a slight regret that the degree of high temperature resistance is limited, but there is no perfect thing in the world, and even so, everyone is very happy and satisfied.

Li Tianfeng changed his words and continued: "However, the advantages of this material are obviously greater than his shortcomings, this material not only has high strength, but also has strong toughness, good hardness, and good machining performance. ”

Very resilient!

Good machinability!

Suddenly, everyone was excited!

Li Tianfeng looked at everyone's expressions, smiled happily, and then said, "However, the machining of this material. It is only limited to casting, turning, milling, drilling, grinding, and not stamping. It should be that this material does not have the same ductility as metallic materials......"

Li Tianfeng introduced the advantages and disadvantages of this material in detail one by one, even if there are certain disadvantages, but the advantages are more obvious, as you know, this is definitely a very good material.

As for the manufacturing cost, it shouldn't be cheap. But the manufacturing cost is very high, so it may not be able to talk about it, and it should be a range that everyone is more satisfied with.

"Hercules" new material was successfully developed. It is exciting news, and many engineers and technicians have heard of this happy event, however, because of the discipline of confidentiality. This matter is limited to Tianfeng Technology.

Tianfeng Technology Company. In the development of the second-generation core machine, many parts and components will use "Hercules" materials, and many R&D personnel did not know what kind of material this is.

It's just that many design sketches drawn by Li Tianfeng have this material on them, the material grade DLS01, and the strength of the material. The performance is noted one by one, although everyone has doubts and doubts in their hearts. But that's how the design works.

Now, everyone finally knows what kind of material this is, and many R&D personnel are happy for a while, and there is really this material, so what else to say, the design difficulty has been reduced a lot.

………

Recently, Zhang Haiping's favorite thing is to study the design and technical outline of the second-generation core machine of Tianfeng Technology Company, and he never gets tired of watching it.

However, the more he studied, Zhang Haiping was a little puzzled, especially the fan and compressor, which put forward high requirements in the second generation of core machines.

According to Zhang Haiping's understanding, the existing material level, if you want to reach such a height, I am afraid that it is still difficult to do it, is there any unique design of Tianfeng Technology Company, so that fans and compressors can achieve such excellent performance.

It's not right, if there is no new material, no matter how high the design level is, I'm afraid that it won't achieve such excellent performance, it's really confusing.

After doubting for many days, Zhang Haiping still decided to ask Li Tianfeng well, and if he continued to think about it alone behind closed doors like this, he might not be able to figure it out after racking his brains.

So, Zhang Haiping called over and told Li Tianfeng about his doubts.

After listening, Li Tianfeng laughed: "Minister Zhang, you are worthy of being from a technical background, I really can't hide it from you, you can see the problems at a glance." ”

Zhang Haiping said: "Mr. Li, do you really use new materials? ”

Li Tianfeng said: "Yes, we have recently successfully developed a new material called 'Hercules', and the fan part, compressor part, and many room temperature parts of our second-generation core machine are all made of 'Hercules' material. ”

"Oh." Obviously, Zhang Haiping heard about this material for the first time, and immediately said with great interest: "Mr. Li, let me introduce it well, what kind of new material is this, listen to this name, this material should be very good!" ”

Li Tianfeng said with a smile: "Of course, this is indeed a very good material. ”

Then, Li Tianfeng introduced this new material in detail, and during Li Tianfeng's introduction, Zhang Haiping exclaimed in bursts of exclamations, and even interrupted Li Tianfeng several times.

After Li Tianfeng's detailed introduction was completed, Zhang Haiping knew that Li Tianfeng would never joke with him, this must be true.

Zhang Haiping said excitedly: "Mr. Li, such a new material can be raised to the national strategic level, and this year's first prize of national scientific and technological progress is estimated to be your Tianfeng Technology Company." ”

In recent years, the annual National Science and Technology Progress Award, there is the name of Tianfeng Science and Technology Company, last year's first prize is Tianfeng Science and Technology Company, this year, it must be Tianfeng Science and Technology Company, such a new material, not good, the National Science and Technology Progress Award is not necessarily.

Li Tianfeng smiled happily.

Zhang Haiping said: "Mr. Li, no, I want to report to the main leaders immediately." ”

Li Tianfeng smiled, and then said: "Minister Zhang, this kind of material, we have just been successfully developed, and it has not yet been mass-produced. ”

Li Tianfeng was worried that after listening to the report, the head of the military was hot-headed, and if tanks, armored vehicles, helicopters, fighters, etc., all need this kind of material, then it would be troublesome, and he would not be able to take it out at all in a short time!

Zhang Haiping understood what Li Tianfeng meant, and Zhang Haiping said: "Mr. Li, don't worry, I understand what you mean." ”

Tianfeng Technology Co., Ltd., Commissioning Engineering Center.

The turbofan 20 engine completed 150 hours of long-term test run, and the engine was disassembled to check that everything was normal, no, after the assembly was completed, the engine entered the high-altitude simulation test bench of the test engineering center.

Tianfeng Technology Company's high-altitude simulation test bench, last month successfully completed the acceptance, participating in the acceptance of a group of experts unanimously commented that Tianfeng Technology Company's high-altitude platform, whether it is advanced technology, or technical level, is far higher than China's first high-altitude platform.

It's a very advanced test bench.

The high-altitude platform is actually a huge building, but inside the building, there is a huge high-altitude test simulation test bench.

The test bench can simulate the high-altitude environment, so that the engine can be tested in a series of high-altitude environments without the need to be mounted on the fighter for test flight.

This turbofan 20 engine was transported to the high-altitude platform, and several technicians and technical workers of Tianfeng Technology Company were installing the engine.

The location where Li Tianfeng is located is a huge test control center. The control center is very large, with an area of two or three hundred square meters, the windows are bright and clean, and the ground is even cleaner to shine the shadows.

It is no longer called the control control room, mainly because it is very different from the monitoring and control room of the ground test platform, not only a lot bigger, all kinds of instruments, equipment, display screens, etc., there are also a lot more, and the test driver is not so many people, but there are twenty or thirty people.

At this moment, everyone was already sitting at their posts, and Li Tianfeng was standing in front of the huge glass in the control center.

Condescendingly, through this glass, you can clearly see the turbofan 20 engine on the test bench.

It didn't take long for everything to be ready, just waiting for the commission, and the deputy technical manager of the commissioning engineering center walked up to Li Tianfeng and asked: "Mr. Li, everything is ready, whether to start the commission." ”

Li Tianfeng waved his hand and said, "Start the high-altitude platform test immediately!" ”

Behind Li Tianfeng, Sun Xiaoping, Qiu Wenan and others, their faces were slightly excited, and the first test run of the high-altitude platform was about to start.

Soon, the alarm bell rang for the first test run, and the test drivers and test technicians were all in place and ready to start the test run.

The test control center, the largest LCD screen, is showing the atmospheric pressure, temperature, humidity and so on of the high-altitude test bench, and now, the test bench is the ground temperature and pressure.

After the third test alarm bell rang, the test commander gave an order, and the test began.

This kind of test run is to simulate the engine taking off from the ground, to high-altitude cruise, as well as high-altitude and high-speed flight, and even including a series of tactical actions, such as vertical climb, high-speed dive, inverted flight and so on.

At the beginning of the test, the engine starts, the engine power climbs rapidly, instead of being as gentle as the ground test car, the high-altitude platform test is very loud at the beginning, and the engine immediately enters the maximum power state.

The afterburner of the engine is turned on, the power is at its maximum, and the air pressure and temperature of the test bench begin to drop, representing the beginning of the aircraft to fly into the air.

According to the high-altitude platform test manual, the high-altitude platform simulates the high-altitude scene, and the engine starts the test flight of one subject at a time.

At the beginning, many test riders were slightly nervous, and their palms were slightly sweaty, and as the test progressed, everyone's nervousness gradually subsided.

Now, everyone's hearts have been slightly excited, a series of test flights, the engine performed well, and the data are completely normal.

10,000-meter altitude simulated test run.

15,000 kilometers, 20,000 meters in the air, a series of test runs, carried out in an orderly manner, you can see that on the huge display screen, the temperature of the high-altitude test bench has reached minus 40 degrees, and the air pressure has dropped to only a few tenths of an atmosphere.

Under such circumstances, the engine perfectly completed some test flights.

"Increase the humidity of the air!"

As you can see, the air humidity of the test bench gradually increases, and under such low temperatures, the air increases, and the engine is most prone to icing.

Once the engine freezes, the situation is very dangerous!

Today's two watches, the second one will be sent. (To be continued......)
