Chapter 1533: Emei

The task of scientific research and production is full, and another benefit is that everyone in the 3611 Institute and the Rongcheng Aircraft Manufacturing Factory is busy, and income has risen with the tide. This brings another benefit. There are more. Excellent talents are willing to work in such enterprises, and the stability of employees who were originally in the enterprise has also been greatly improved.
For example, Yang Wei, who had been a "tour guide" for Tan Er for a few days, did not have the idea of ​​going abroad like another time and space, and he did not need his tutor Song Wenhua to leave Ma Xiaozhi to stay with emotion and reason. China has left behind the future leader of China Airlines — in fact, Yang Wei's small life is now more and more moist. Because of his outstanding work ability, he has taken the lead in the flight control system of the "J-10" fighter. The key responsibility of presiding designer has also fully verified many of his original ideas on the "Xiaolong" fighter, and gradually showed the style of 3,611 young leaders. Of course, the job title, job title, and income follow. The increase in number, coupled with the fact that he and Tan Zhenhua have always been known as "senior brothers", although the number of times the two have met is limited, the communication on the phone has never been interrupted. This is the help of Yang Wei's upward climb.
Tan Er's elbow-like temperament is well known in the world, his friend, who dares to suffer? Besides, this is China’s largest cash cow. He hugged his thick legs tightly. When he was short of money, he shook his hair. The root hairs are thicker than other people’s waists. Who do you think is okay with his wallet?
Of course, Yang Wei himself is also proud to be friends with Tan Zhenhua, who is well-known in the world-you see, when the meeting started just now, he was the one who took the lead in whistling to welcome the second son!
"From this point, we can also see that if the big push we discussed just now is geared towards the future, then the middle push is the key to solving the most pressing problems we are currently facing in China." Liu Daxiang continued, "Considering The reality is that our country will not be able to equip a sufficient number of heavy twin-engine fighters for a long time. However, the "J-10" fighters have adopted more new technologies due to their higher technical difficulties and higher design indicators. It will take several years to complete the development, and it will take longer to actually start mass production of equipment, so it can achieve more than 70% of the combat effectiveness of the "J-10" and can completely replace the "J-6", "J-7" and "Strong Five". "Fierce Dragon, a light fighter equipped with a mid-engine engine, is a good choice for this transition period, and the prospects for the international export market of this fighter are also very promising. Therefore, we believe that we will continue to make small changes to the "Huashan" engine. We need to stick to the route, but because this type of engine is also derived from "Speey", the technology is a bit old and the potential is limited. It is difficult to significantly increase its thrust-to-weight ratio. Therefore, our opinion with Xihangfa is, The improvement of this type of engine is mainly to extend its service life and improve its maintenance performance, and it will not be extensively modified on a large scale."
"It seems that you are putting your hope on "Turbofan 12"." Minister Zhang nodded and said: "You have been working on this subject for over ten years. Then, when will we see the results available?"
"Turbofan 12" is an engineering model project of the results of the "High Push Pre-Research" project that year, and its follow-up investor Tan Zhenhua personally named it "Emei".
"From the beginning of 1989 when the national acceptance of the pre-research project was completed, to the beginning of 1991, our Gas Turbine Institute and Xihangfa have worked together. With the strong support of Dr. Tan, the development of the core engine has been completed and the project has been completed. All experimental subjects have verified that the performance of the core engine is in full compliance with the original design requirements. Since 1991, we have been promoting the matching of low-pressure turbines and fans. Now I want to report to you good news. After two years of hard work, "Vortex The engineering verification machine for Fan 12
has been completed the day before yesterday. After the first ignition test, at 80% rotation speed, the engineering verification machine platform runs smoothly and the power output is normal. The test was successfully completed!"
"Wow!"
There was a round of applause in the house!
For these people here, they certainly understand what the success of this experiment means to China!
"Turbofan 12" is in the true sense. China’s first fully forward-developed turbofan aeroengine. Although it is only an 8-ton thrust mid-engine, its success will mark that China has become Countries that can independently develop turbofan aeroengines!
Although Tan Zhenhua first started from Luoluo, then from Wukelan, and then from Rakshasa, he has acquired many types of aero engine technology, but those are other people’s things after all. It is naturally good to use them to solve the current problems. They are used for learning. The information is more ideal, but everyone understands that only after studying, the knowledge and technology that they have mastered are their own, and they can be guaranteed to be able to use them independently in the future and completely free from external factors!
In this sense, "Turbofan 12" will create an era and become a milestone in the history of China Aviation Development!
"Tell everyone about this engine." Minister Zhang said with a smile on his face.
"Okay." Liu Da wanted to respond: "Turbofan 12. The current engineering verification machine parameters are: full authority digital control, three-stage low aspect ratio shoulderless fan, seven-stage compressor, one high and low pressure turbine. Stage, short burst diffuser ultra-compact annular combustion chamber, engine bypass ratio 0.5, length 4010 mm, fan inlet 880 mm, engine maximum diameter 905 mm, total boost ratio 23, turbine front temperature 1600K, air flow 80 kg per second, The maximum military thrust is 5,300 kg, the maximum afterburning thrust is 8,700 kg, the engine weighs 1,080 kg, and the thrust-to-weight ratio is 8.05."
"Wow, can achieve a push-to-weight ratio of 8 or more!"
Except for a few people who had known some inside information beforehand, everyone else involuntarily exclaimed.
"Yes, it can achieve a push-to-weight ratio of 8 or more!" Liu Daxiang repeated with a red face: "Compared with the big push, the technical difficulty of the middle push is slightly lower because it can also achieve a higher push-to-weight ratio. This is largely due to our previous cooperation with Rolls-Royce, which allowed us to sort out the normal design ideas and principles of Hangfa and establish a scientific project management system. There have been many breakthrough research results in the fields of materials science and processing technology, and we still have one more work to report to everyone—"
Speaking of this, Liu Daxiang paused deliberately, looked around for a while, and continued after selling enough: "We expect to complete the test work of the verification machine within 3 years, and at the same time move to the stage of engineering mass production models. The institute will launch another topic at the same time-the application of new technologies and new materials to reduce the weight of the engine. The ongoing topics include further optimization of the compressor structure, the practical application of the second-generation domestic high-temperature turbine blades, and ceramic matrix composites. Material tail nozzles, powder metallurgy integrated turbine discs, etc., these topics are currently progressing smoothly. It is expected that after the application of these new technologies, the temperature in front of the turbine can be increased by 100~150K, and the engine will be increased by 15%~20%. Our goal is to achieve a 9-level push-to-weight ratio!"
Quiet, extremely quiet!
