readx; 624 construction of ultra-large flow of high-altitude platform, this is after several years of internal debate within the company, before the final determination of the project, the previous super large flow of high-altitude platform is planned to be built to Guiyang side of the 0112, but later after the establishment of United Aero Engine Company, 0112 as a part of the company, in the construction of such a large project as a high-altitude platform, must be considered comprehensively.

On the one hand, there is already relevant experience in the construction of high-altitude platforms, and on the other hand, after considering the centralized construction and use of high-altitude platforms, then some of the infrastructure supporting the SB-101 project before can actually be shared, and the savings are all wasted silver.

After determining that this construction site is not building a hall and hall, but after the construction of the super-large thrust turbofan needs to use the ultra-large flow high-altitude platform, Yang Hui said that this is very good, as long as the 624 Institute can keep up with the construction of the new high-altitude platform, although other aspects also need to update some test equipment, but the construction cycle and cost required for those equipment updates will be relatively small, and it can be done slowly after a period of time.

Carefully looked at the construction area under construction here, and compared with the area of the previous SB-101 high-altitude platform, there is indeed a big difference between the two, although Yang Hui has not seen the world's largest flow high-altitude platform built by the United States for the development of super-large bypass ratio turbofan engines, but when Yang Hui visited the Soviet Union before, he went to see the super-large flow high-altitude platform project built before the collapse of the Soviet Union, and the area of that guy is indeed larger than that of the general flow high-altitude platform.

Tilting his head to ask: "When will the project plan be built, and when will it be officially put into use, and now the company has spent so much money to invest in a super-large flow high-altitude platform, so the construction progress of the high-altitude platform on your side is very important." ”

Anyway, military engines with afterburners are not used, and as long as the bypass ratio of civilian engines is not more than 7, it will also not be used, and other small and medium-sized thrust engines will not use the new high-altitude platform, and SB-101 can fully meet the requirements.

"Mr. Yang can rest assured that the construction progress of the high-altitude platform on our side is strictly in accordance with the provisions of the development progress of the engine project over there, and the institute has also set aside a two-year margin to prevent failures in the construction of the high-altitude platform, or the development progress of the engine is accelerated. As for the construction party's statement, all our civil infrastructure work should be completed in the first half of next year, but the installation and commissioning of the equipment may take a little time, at least about 98 years to complete, and a conservative estimate may be completed around 2000. ”

The construction of the high-altitude platform is definitely not so easy, the SB-101 project went through a total of about 20 years, and later the 624 Institute assisted the turbine alliance company in the northeast of AVIC to build a set of high-altitude platforms of the same level as the SB-101 technology, so the current 624 Institute can be regarded as having sufficient relevant experience. However, the construction project is really not simple, as the world's top super-large flow high-altitude platform, you must know that even if it is as strong as the Soviet Union, it has not been able to completely build the entire high-altitude platform until its death, and then it even almost became an unfinished project.

Now 624 said that it will take another 5 years to ensure the success of the construction of the high-altitude platform, in fact, this is not a long time-consuming, considering the development progress of the new super-thrust and large-bypass ratio turbofan engine, it is more appropriate to form a working test capability around 2000.

"The efficiency is not low, if you count the time of the company's research on the ultra-large flow core machine project, and then consider that there is still a long time before waiting for the development of key projects of related equipment factories, the start time of this project will be pushed to at least 1990, so the ultra-large flow high-altitude platform project will take a total of 10 years!"

As the world's top high-altitude platform, the whole construction took ten years, which even caught up with the development cycle of a key aero engine, and the development of an engine is about five years ahead of the development of the aircraft, so the aviation industry is really a great test of a country or a company's heritage, accumulation, this is definitely not a joke.

Compared with the planned future wide-body cargo aircraft project, it is necessary to start the construction of the high-altitude platform in 90 years, and now the super-large thrust turbofan engine can be established in about 95 years, and then it will be possible to finalize the engine in 07 and 08 at the earliest, and then install the corresponding twin-engine wide-body cargo aircraft test flight, and finally even if everything goes well, it will be at least until about 2010.

Looking back, from 1990 began to prepare the relevant test equipment, to the end of 2010 it is possible to launch the final aircraft finalized model, so the aviation industry really wants to develop greatly, without more than 20 years of accumulation is completely impossible, and this is still based on the intermediate project must not have a big problem, the national policy can not be repeated, the technical road is also on the right path, otherwise a little attention is a waste of decades of time, in the end it can only be a gap getting bigger and bigger.

The construction of the high-altitude platform can take ten years, but fortunately, AVIC Southwest has an overall plan, so that there will be no major problems, and this is also the meaning of Yang Hui's existence over the years, looking at the construction of the world's top aviation manufacturing scientific research equipment little by little, AVIC Southwest to become the world's top aviation manufacturing giant is just around the corner.

"Let's go, there is nothing to see at this construction site now, and we will not disturb the work of the construction party, you take me to the scientific research center of the institute to see, there should be only one project in the institute now, and this project is also the focus of the company in the future for a period of time, so this time we must be cautious."

The relevant pre-research/project approval work of the fourth-generation military high-altitude platform is actually not later than the development progress of the super-large flow high-altitude platform, and now the super-large flow high-altitude platform has accelerated the progress, which is considered to have entered the fast lane of project construction, so the development of the fourth-generation military high-altitude platform must not lag behind.

Yang Hui thought that he was going to go to the scientific research building, but he didn't want to be taken directly to the SB-101 next to him, and he listened to someone explain: "The core aircraft of the fourth generation has solved most of the engineering problems in terms of design, and now the core aircraft is being fully tested in the high-altitude platform, so we can go directly to the high-altitude platform this time."
