- Of course, if you want to successfully promote the "No Regrets" plan, you cannot just have a passion for it. After all, Ascendas Group is essentially a company, not a charity that buys for free at zero yuan.
¡°If Zhuang Jianye had an impulse and started making aimless bets with the Ascendas Group, it would probably take less than 15 years and less than two years for the Ascendas Group to have all its assets wiped out.
What's more, aviation engines are definitely a field where slow work requires careful work. If the experience is not met, the level cannot be improved, and the technology cannot be broken, it is useless to have empty ideals, because the world is such a reality, and power can only be generated with love. Moving those brainless novices cannot change the cruel world.
So making money and gaining experience have become two major problems for Zhuang Jianye.
Needless to say, making money is a great cause that Ascendas Group has been deeply engaged in as always. However, this obsession with profits has penetrated into the bones of everyone in Ascendas Group. If we really want to start it, Ascendas Group will rely on many technological innovations in its hands. New profit growth points can always be found.
The difficulty is the accumulation of experience, especially the accumulation of applications in the pure aviation field.
The reason why Americans can lead the world in aviation development, no matter what else, is that the huge and explosive accumulation of experience in their hands can make most people feel despair.
Precisely in this aspect, Ascendas Group is really inferior to its younger brother compared to European and American giants.
Not to mention other things, in order to modernize aero-engine testing, Ascendas Group has invested heavily since the early 1990s to introduce a complete set of large-scale aero-engine test and monitoring equipment from Europe, including a set of air cannons for bird impact tests. .
It can launch birds up to 4 kilograms, simulating the ultra-high relative speed between birds and aircraft during aircraft flight, and then use advanced inspection and testing equipment to obtain data on the production of aero engines during such processes, so as to make targeted decisions. improvement of.
At that time, Ascendas Group¡¯s wd-60ml large bypass ratio turbofan engine had just rolled off the production line, and it was necessary to conduct this kind of bird impact test with important safety indicators.
As a result, this was done seven or eight times in a row. After each impact, the first-stage fan of the wd-60ml large bypass ratio turbofan engine was shattered by the high-speed corpse shot by the air cannon, causing the fan blades to be sucked into the engine. This can cause damage to the compressor or even the turbine blades or even the entire engine to be scrapped.
This resulted in a huge delay in the delivery of the wd-60ml large bypass turbofan engine that was supposed to be put into use at the beginning of last year, so that the Y-17 that rolled off the production line had to use the Russian-made D-30kp turbofan engine to barely win. Get your birth certificate.
At that time, everyone in the Ascendas Group had a headache. They looked through countless information, conducted various experiments, and even made the fourth-generation Z-shaped fan blades. However, it was still of no use. The birds fired by the air cannon were Just like the fifty or sixty times energy bomb, the fan blades that Ascendas Group worked so hard to make were riddled with holes, making them look like paper.
In the end, I really had no choice. No one could afford the cost of the engine, so I had to go to my European colleagues to ask about their experience. It turned out that the Europeans were quite enthusiastic and sent a team of experts to investigate. Then he said something to Ascendas Group: "Just thaw the frozen chickens, ducks, and geese, otherwise what you will launch will not be test birds, but cannonballs!"
With this sentence, Ascendas Group not only paid for six aero engines worth tens of millions, but also paid only US$6 million in consulting fees for this expert group that came to China.
This past incident will be almost like a joke in the future, but it also shows from another aspect that although Ascendas Group has entered the threshold of advanced aerospace engineering, it is still far away from being admitted.
There are many similar situations. Ascendas Group has also encountered many obstacles along the way, but most of them can get through smoothly after paying a "tuition fee". However, when it comes to the application stage, Ascendas Group has difficulties.
There is no other domestic model that can adapt to wd-60ml except Yun-17.
Originally, the Northwest Aviation Factory had the intention to graft WD-60ml onto the H-6. After several tests, it was discovered that a large bypass ratio engine such as WD-60ml could not fit into the engine compartment of the H-6. As for other types of civil aviation aircraft , foreign brands simply do not respect the credibility of Ascendas Group and refuse to assemble.
There are no large civil passenger aircraft of more than 80 tons in China. Ascendas Group itself has plans in this regard, but they are still on drawings. It¡¯s not that they don¡¯t want to implement them, but the supporting industrial chain is not yet complete. Ascendas Group just wants to do everything. can not do this.
There is no way. The production and manufacturing of large aircraft with a take-off weight of more than 80 tons is a new field. Not to mention other things, just talking about the landing gear of this kind of aircraft, ordinary technology cannot support such a huge body. Use everythingThe above hydraulic section or hydraulic section can deeply forge the blank like kneading dough.
¡°There are very few heavy-duty equipment of this kind in China, and even the few units they have are in the fields of shipbuilding, ordnance, nuclear energy, etc. The little bit of production capacity is simply not enough to support the production of this type of aircraft.
Of course some people will say that the McDonnell Douglas 80 and McDonnell Douglas 90 are aircraft of this level. Aren¡¯t they already domestically produced?
It is localized, but this kind of localization needs quotation marks, because most of the core spare parts for these two models of McDonnell Douglas are provided by McDonnell Douglas, and the country is only used as an assembly base. .
??Including the landing gear of two aircraft.
Of course, even if the landing gear is solved, if you want to complete the manufacturing of large aircraft, there are still many domestic shortcomings. For example, the single-aisle wide-body passenger aircraft designed by Ascendas Group uses 35% of composite materials, including two cabins. The segment and foot wings need to be molded in one go from carbon fiber composite materials.
The problem is that Ascendas Group has a good idea, but there is no large-scale hot-pressure filling of more than ten meters in China and large-scale laser spraying equipment that can realize multi-position spraying of woven carbon fibers.
Japan and the United States have such equipment, but the problem is that they won¡¯t sell it for how much, and they don¡¯t even bother to do it for you. The reason is very simple. Can Ascendas Group guarantee continuous procurement for half a year? If not, take it with you wherever you can to cool down.
This is what the aviation industry often calls the ceiling of large aircraft.
?????????????????????????????????????????????????????????????????¡
No, the threshold is really too high and the scope involved is so large that it is impossible to get on.
Ascendas Group has naturally encountered this opaque ceiling and is even more isolated than other similar companies. At this time, it is no longer appropriate to survive. In this case, what should we do?
The Russian aviation industry led by Novak Djokovic is making a grand visit to China. Since it is a cooperation, naturally you guys can¡¯t just make an advantage, and you won¡¯t take advantage of anything in China, right?
????????????????????? At least some blood needs to be shed, otherwise those Dawari clan, Hala Shao, Ulla~~ and so on will be in vain!
