Tomorrow is 515, the anniversary of the www.biquge.info of Biqu Pavilion, the day with the most benefits. In addition to the gift bag and school bag, this time the 515 red envelope must be turned over, how can the red envelope not be robbed, set the alarm clock high~

624 as a national scientific research institute, they are indeed a little hard to live in the last place, but now with the Southwest Science and Industry sideways, 624 is now like a fish in water, from the Southwest Science and Industry of various scientific research, testing projects, so that 624 is quite moist and fulfilling.

In particular, the CG-2000 engine project team stationed in the 624 institute, after the start of a two-year period of various high-altitude tests, after all, it is the first large bypass ratio turbofan engine of the Republic of China to be tested here, and at the same time, there are two internationally famous aero engine research units from Germany MTU and Ivchenko of Ukraine to participate in the project, 624 Institute provides venues, equipment, and naturally learns a lot of technology, and everyone communicates and learns from each other in the project.

No, when Yang Hui arrived at the 624 Institute, the high-altitude platform was still working, and the huge roar made people hear the movement here from afar, Yang Hui was still very satisfied with the test work carried out here, but he remembered that Chief Wen said that the CG-2000 engine could be finalized in 92 years at the earliest, and the airworthiness certificate could be obtained.

Hearing the roar of the engine, he walked into the pile of scientific researchers who were still paying attention to the test count just now, and in the middle of the crowd were technicians from the Ivchenko Design Bureau, who seemed to have some skills and status, and had only come to the unfamiliar environment of 624 for a few months to be able to skillfully put into work. This still requires some ability.

However, the engineers of MTU are a little confused, and it seems that the Germans are not omnipotent. After all, it is a country that is focused on and taken special care of by American fathers, and Germany's aero engine industry is really not good. Especially the whole machine manufacturing and follow-up testing and improvement work, he is really not good.

The most important thing now is to find Chief Engineer Wen, Chief Engineer Liu, and the relevant technical person in charge of the German MTU, only in this way can the increase plan be decided quickly.

The office area of 624 is still the same as before, the only difference is that there is more people in comparison, both Chinese and foreign scientific researchers.

"After walking in and asking, I found out that all the senior management was conducting weekly row meetings, and the entire CG-2000 scientific research experiment schedule was released from here. Since all the technical executives of the CG-2000 are in the conference room. That's just right! ”

Find the staff, go in and inform Mr. Wen, and then wait outside the door to go in and attend the meeting

It is true that it is not wrong to say that the top management of the CG-2000 engine project is here, but all the directors of some important subsystems related to this engine are in place, and so many people can express their opinions, and it seems that all kinds of ideas can be heard.

"Okay, since everyone is here, I'll just say the purpose of this time. The development of the CG-2000 engine is about to be finalized. We have to start thinking about its subsequent improvements in advance, this is a path that must be taken for the development and growth of a mature aero engine, and I am here for this! ”

Everyone knew that what Yang Hui said was not false at all, and even thought of their own improvement plans in their hearts. But when it comes to it on the table now, it still feels a little too early, after all, even the basic model is still being tested.

But Master Wen thought more clearly. As soon as the idea was raised, he directly proposed the plan.

"Improve the design. It is necessary to form the CG-20000 engine into a series. I have also begun to do this consideration, in my opinion to increase the engine is more in line with our actual situation, reduce the thrust of the CG-2000 in the complete use of its market, after all, our MPC-75 passenger aircraft fuselage is already very stubby, which shows that MPC-75 will definitely develop in the future, as a supporting engine, we must also support together to increase thrust to meet the development needs of MPC. ”

Although Mr. Wen had not heard of MPC's follow-up development plan, he couldn't stand the viciousness of people's eyes, and from the technical aspect, he could see at a glance that the aircraft could only be bigger in the future, and now he also proposed to make the thrust of the engine bigger, which aroused the recognition of others.

The affirmative words that come out from time to time easily determine one thing in everyone's hearts: the CG-2000 can only increase the thrust, and it must not be designed to reduce the thrust.

Looking at the crowd, it is determined that the follow-up improvement of this engine will only increase the thrust, Yang Hui must be happy to see it, the scientific research team has its own vision to see the future market and development path, this is not exactly the current Republic of the scientific research community needs a kind of ability?

"That's right, this time I want to participate in the first aircraft of MPC-75 with United Passenger Aircraft Company, the progress is very good, the project is very successful, and their follow-up improvement design plan is indeed as guessed by Chief Wen just now, the target is the narrow-body trunk airliner market occupied by 737 and A320, so the goal of our CG-2000 engine is also determined: CFM-56 or V2500 engine, which is more similar to our thrust range."

This person, once its ambitions are not made public, it is easy to go crazy, especially when the colleagues around him also have this idea, then it is even more impatient.

The first to speak was not the second chief engineer Wen, nor the 624 chief engineer Liu, but the deputy chief engineer of the Ivchenko Design Bureau, who had very good technical ability, did not say a word on the side, and the only one left was the chief engineer of the MTU side.

"I absolutely agree with this, the thrust of the CG-2000 engine is increased, and the CFM56 engine to increase the market is our only way out, the narrow-body trunk airliner market is the most demanding party in the civil airliner, as long as we successfully enter this market, then we are the second CFM-56."

The CG-2000 project is different from the MPC-75 project in that the MTU company's share in the entire project has not reached 50 percent, and the 60 percent share firmly grasped by Southwest Science and Industry is destined to see more about the development of this engine in the future, but fortunately, everyone's ideas are the same now, and it is naturally best if there is no disagreement between the partners.

"Since it is determined that the future of the engine is to take the route of increasing thrust, then everyone thinks that we should start from those aspects to increase thrust, after all, there are so many engine subsystems, and there are various plans to increase thrust, we need to formulate a technical plan suitable for us according to our own specific situation, does Mr. Wen have any ideas?"

The determination of the specific technical route is indeed a point that needs to be considered, and if the determined technical route is excellent enough and in line with the specific situation, it will be very helpful for the subsequent engine development and can be smooth sailing, so Yang Hui attaches so much importance to the determination of the technical route at this time.

When it comes to the determination of the technical route, the current Chief Wen really does not have a very suitable plan, and he knows the current technical reserves of Southwest Science and Industry.

"With our current technology, to develop a narrow-body trunk airliner engine, even the 737-300 airliner on the CFM-56-3 engine is more difficult, which requires our engine thrust must reach more than 9.5 tons, which means we must add 2 tons of thrust on the basis of the current CG-2000 engine."
