Chapter 1170 Are the Chinese going to throw the blame?
The Aerospace Power Group's publicity campaign was quick.
Just two days later, an article signed "Chang Gong" was published in the China Aviation News published on Friday——
"The West is not bright and the East is bright - my country's first large bypass ratio turbofan engine completed the first phase of testing"
On the surface, this appears to be just an ordinary promotional report of an achievement.
Not only was the specific model not mentioned.
Moreover, terms such as "first phase testing" are also very vague, and there is no unified standard at all.
We can only guess the meaning between the lines.
Therefore, under normal circumstances, except for internal colleagues and some enthusiasts who are interested in this field, almost no one will pay special attention to this kind of report.
However, this time the situation is different.
For example, “create cross-century leading equipment, carry out in-depth research on cutting-edge science and technology, boldly innovate design theoretical systems, and comprehensively conquer key core technologies...” and “achieve a series of major breakthroughs, achieve fundamental changes in research and development methods, and achieve intergenerational leaps in product levels. ..." Such regular content is of course essential.
But in the second half of the report, the author changed his tone and dedicated nearly one-third of the space to discussing what characteristics the next generation of aviation power should have.
First of all, it was mentioned that at the IPCC assessment kick-off meeting, the emission data released by the United States was questioned, which triggered the increasingly urgent pressure on mankind to reduce emissions——
"As a member of the human race, we certainly hope that this is just a good misunderstanding, but considering that the United States has still not given a reasonable explanation for this matter so far, it has also deleted the past posts on its official website of the Environmental Protection Agency. The infrared spectrum of the atmosphere forces us to consider the possibility that this allegation is true
If we assume that since 1992, when countries signed the United Nations Framework Convention on Climate Change, the United States has concealed 30% of its domestic carbon emissions levels from the public every year, that means that by now, there have been about 40 billion tons of additional carbon dioxide Entering the atmosphere, which will undoubtedly further increase the difficulty of curbing global climate change.
Although the responsibility for excessive emissions undoubtedly lies with the United States, the urgency of mitigating climate change must be faced by all mankind. According to calculations by the International Civil Aviation Organization, the average annual carbon emissions of aviation/maritime transportation and related industries around the world The volume is at the level of 2 billion tons, and will gradually increase with the increase of global trade volume.
Obviously, the CAEP4 emission standards formulated by the Aviation Environmental Protection Committee are no longer able to adapt to the current emission reduction pressure. Therefore, we are considering revising the new civil aviation technical standards and formulating more stringent emission limits in the next stage, such as requiring aircraft engines and gas turbines. Cruise fuel consumption is reduced by 10%, carbon dioxide and nitrogen oxide emissions are reduced by 16% and 30%, and new detection requirements for carbon monoxide and unburned hydrocarbons are added...
…”
In short, it is a eloquent four to five thousand words. It first establishes the position of the victims of climate change, then extremely "magnanimously" states that the hole dug by the Americans needs to be filled by everyone's concerted agreement, and finally states that the shipping industry controls carbon emissions. necessity.
Anyone who comes must first praise the layout.
After it was published, Chang Haonan felt that there was not enough news, so he continued to report it to the higher ups, and finally inserted a text message of about 20 seconds into the 7 p.m. news.
As a result, it soon attracted a higher level of attention than before...
In fact, at the beginning, most people focused on the first two-thirds of the content.
After all, it has been more than two years since the Yun-9 project was established, and many news indicate that the No. 01 prototype using imported engines may make its first flight in the near future.
Some wall-crawlers in the Nanzheng area even photographed a yellow-skinned twin-engine transport plane parked inside a factory.
By 2005, the Internet had become quite popular in China, and chat rooms that only a handful of people could enter in the early years had gradually developed into larger forums with more concentrated traffic.
Therefore, the speed at which relevant news spreads is already extraordinary.
[I have an uncle who works in the Qin Fei Group and told me that this aircraft should be planned to replace the Y-8. The twin-engine turbofan has a longer range, a larger load capacity, and is quieter than the four-engine turboprop. /Applause//Applause/】
[This yellow leather aircraft looks like it should be equipped with two PS90A. Its take-off weight should be about 70-80 tons, which is slightly larger than the Yun-8, but it can also be regarded as the same level. And look at the report a few days ago. I mean, after replacing the domestic engine, the performance is expected to be further improved, and it can match the situation mentioned by the original poster / salute /]
[Just asking if you don’t understand, will replacing four engines with two have any impact on reliability? As a tactical transport aircraft, the Y-8 should also have the ability to take off and land at field airports, right? 】
[You can’t just look at the number of engines. After all, both the foundation of the An-12 and the turboprop 6 itself are too backward, so even if it is replaced with two new turbofans, the reliability will be significantly improved. As for taking off and landing at field airports It’s not even a problem. Even the IL-76 and C17 can actually do it. The key is the landing gear design rather than the engine...]
[I think this new medium-sized transport aircraft is about to fly for the first time. For reference, the American C17 first flew in 1991 and entered service in 1993. It is possible that like the J-11 modification, the first batch or the first two batches will use PS90A. Subsequent batches will be replaced with domestically produced power/make fists//make fists/]
[According to general experience, it is true, but I feel that the research and development progress of domestic aviation engines has been quite fast in recent years, so it is hard to say, maybe we will catch up with the first batch of service...]
[When you mentioned this, I suddenly remembered that the author of the report in the Aviation News was named Chang Gong. Could it be that he was the vest of Academician Chang of the Aviation Power Group? 】
[I think what you said makes sense...]
【……】
Posts like this soon appeared in almost all domestic military and aviation enthusiast forums.
In this timeline, when China has fully entered the Internet era, both the Turbojet 14 and the Turbofan 10 are already quite mature models.
Moreover, it is no secret that China participates in the design and manufacturing of the M88 and SeA650 engines.
As for the "shortcomings" of domestic aviation engines, these are things that only the previous generation of military fans can clearly remember.
Therefore, everyone is generally quite optimistic about the progress of the new engine.
Many people also gave Chang Haonan a thumbs up.
However, optimism is optimism.
But most people completely miss the point.
Chang Haonan was somewhat dumbfounded.
Fortunately, there are still some people in the industry who are keenly aware of the key points of this report...
...Birmingham, UK.
Tim Purdy entered Panos Watson's office with a brief in hand.
At the end of 2004, the Airbus A380 No. 1 prototype equipped with the Trent 900 was publicly unveiled and officially confirmed to make its first flight in March 2005. The latter, who was originally solely responsible for this model, was naturally promoted and became He became the deputy director of Rolls-Royce Group's entire civilian product line.
Officially became a member of the core power level of the group.
As the tide rises, other members of the same project team will naturally receive corresponding promotions.
For example, Bodie, while retaining the deputy director of the Trent 900 project, began to preside over the New Generation Medium Thrust Turbofan Engine (NGME) project, which is what Champine mentioned before and is adapted to the new generation Airbus A320. Aircraft aerodynamics.
The project team has temporarily named it Trent 300.
Of course, I just borrowed the name of this world-famous series.
If nothing else happens, the design should still start from scratch, using a relatively simpler dual-rotor structure.
There are still some differences on whether to learn from the V2500 experience.
Recently, Bodi has come to talk to Watson frequently, just to obtain more abundant resources to implement the work into the specific demonstration stage as soon as possible.
But at the moment, the decision-makers, including Watson, apparently still think Champine's warning is a bit alarmist.
With a cash cow like the V2500 on hand, the Trent 900 and the Trent 1000 engines adapted for the Boeing 787 have higher priority.
But after all, Purdy is the most important confidant of Watson, the new executive, and he also knows some ulterior secrets in the Trent 900 project.
Therefore, it is not easy for the latter to refuse the other party's request very forcefully.
Therefore, Watson felt a bit of a headache as soon as he saw Bodie appearing at the door.
Fortunately, this time, Bodie really wasn't looking for trouble.
"Panos, I'm not here to ask you for money this time. Don't look sad when you see me..."
Without warning, he pulled a chair from the side and sat across from Watson, while placing the briefing in his hand in front of him:
"Come and see this."
Although Watson was a little skeptical after hearing this, he was still a little relieved:
"Thank God, you finally have something else to talk about with me..."
Then put on your glasses and pick up your briefing paper.
Above is about half a page of a newspaper.
It seems to be from China.
Of course Watson doesn’t understand Chinese, but fortunately the second page of the briefing provides a complete translation and analysis.
"New high bypass ratio turbofan engine..."
Like everyone who had just seen this report, he first paid attention to the aircraft engine model mentioned in it.
"I know this model...according to speculation, it should use the core machine of their turbofan 10, and is going to be used on military transport aircraft instead of the Russian-made PS90A."
As a professional technician, Watson has been tracking the development of his peers.
Only after my recent promotion, the frequency of attention has dropped slightly.
But Bodi shook his head directly:
"The first part is not important, look at the second half..."
Watson was stunned for a moment, and then he turned to the third page of the briefing.
"The second half..."
As a result, before even looking twice, I couldn’t help laughing:
“It seems that Americans are in a very awkward situation with China on the climate issue...”
People in his position naturally know that the core of these climate and environmental protection issues are business and have nothing to do with saving the earth and saving mankind.
But don’t delay watching American jokes.
However, Watson’s smile soon solidified on his face:
"Hope that the new standard's cruising fuel consumption will be reduced by 8%? Carbon dioxide and nitrogen oxide emissions will be reduced by 16% and 30%?"
Perhaps because his throat was dry, his voice was quite strange at this time.
However, Watson no longer cared to pay attention to this.
These numbers almost made his eyesight go black:
"Chinese people can't get their share of the cake, so they want to smash the table?"
