Take Off My Aviation Era

Of course, if you want to smoothly advance the "No Regrets" plan, it is not enough to have a passion. After all, Ascendas Group is essentially an enterprise, not a shantang for free zero yuan purchase.

If Zhuang Jianye is impulsive and pats his head, he will take the Ascendas Group and start betting aimlessly, it is estimated that it will not take 15 years, and within two years the possessions of the huge Ascendas Group will be exhausted.

What's more, the aero engine is definitely a field of slow work and meticulous work. If the experience is not up to the level, the level cannot be improved, the technology cannot be broken, it is useless to have ideals, because the world is so realistic, and only power can be generated with love. Touching those brainless little whites can't change the cruel world.

So making money and gaining experience have become two major problems for Zhuang Jianye.

Needless to say, making money, this is the great cause of Ascendas Group, as always, how this persistence in profit has penetrated into the bones of everyone in Ascendas Group, and it really wants to be mobilized. Ascendas Group relies on many technological innovations in its hands. Always find new profit growth points.

The difficulty is the accumulation of experience, especially the accumulation of pure aviation applications.

The reason why Americans are ahead of the world in aviation development, regardless of the fact that their vast and explosive accumulation of experience can make most people feel desperate.

Precisely in this respect, Ascendas Group's comparison with European and American giants is really not as good as the younger brother's level.

Not to mention other things, in order to realize the modernization of aero engine testing, Ascendas Group has invested heavily in the introduction of a complete set of large aero engine testing and monitoring equipment from Europe in the early 1990s, including a set of air cannons for bird impact testing. .

It can launch up to 4 kilograms of birds to simulate the ultra-high relative speed of birds and aircraft during flight. Then, through advanced testing and testing equipment, the data produced by aero engines in this process can be obtained to make targeted improvement of.

At that time, the WD-60ML turbofan engine of Ascendas Group had just rolled off the assembly line, and it was necessary to do this kind of bird impact test with important safety indicators.

The result was seven or eight consecutive times. After each impact, the first-stage fan of the WD-60ML turbofan engine with a large bypass ratio would be shattered by the high-speed corpses shot by the air cannon, causing the fan blades to be sucked into the engine. The compressor and even the turbine blades are damaged or even the entire engine is scrapped.

This caused the delivery schedule of the WD-60ML large bypass, which should have been put into use at the beginning of last year, to be greatly delayed than the turbofan engine, so that the off-line Yun-17 had to use the Russian-made D-30KP turbofan engine to be barely able to get it. Under the birth permit.

At that time, the Tengfei Group had a headache. It turned over countless materials, did various experiments, and even made the fourth-generation Z-shaped fan blades. There was still no use for eggs. The birds launched by the air gun Like fifty or sixty times the vitality bomb, the fan blades made by Ascendas Group's brainstorming are riddled with holes, just like paper paste.

In the end, there was really no recruit. The engine was so expensive, and no one could afford it. So I could only ask my colleagues in Europe about their experience. The Europeans were still very enthusiastic and sent a team of experts to investigate. Later, I gave the Ascendas Group a sentence: "Just thaw the frozen chickens, ducks, and geese, otherwise you will not launch test poultry, but shells!"

In this sentence, Ascendas Group not only paid six aero engines worth tens of millions, but also paid only US$6 million in consulting fees for the expert group coming to China.

This past event will be similar to a joke in the future, but it also shows from another side that although Ascendas Group has entered the threshold of advanced aviation development, it is still a long way from entering the hall.

There are many similar situations. Ascendas Group is also stumbling along the way, but most of them can go there smoothly after paying a "tuition fee". However, it is difficult for Ascendas Group to implement it in the application stage.

There is no second model except Yun-17 that can be adapted to WD-60ML in China.

Originally, Northwest Aviation Plant intended to graft WD-60ML onto the H-6. After several tests, it was discovered that the large bypass engine of WD-60ML could not fit into the engine compartment of H-6 at all. As for other types of civil aviation aircraft , Foreign brands simply ignore the credibility of Ascendas Group and refuse to assemble.

However, there are no domestic large-scale civil airliners of more than 80 tons. Ascendas Group has its own plans, but it is still on the blueprint. It is not that it does not want to implement it, but the supporting industrial chain is not complete. Ascendas just wants to do everything. can not do this.

No way, the manufacturing of large aircraft with a take-off weight of more than 80 tons is a new field. Let alone the other, the landing gear of this aircraft cannot be supported by ordinary craftsmanship. It is only necessary to use a hydraulic section or hydraulic section of more than 10,000 tons to perform deep forging of the blank like a dough.

However, there are very few such heavy equipment in China, even if only a few are in the fields of shipbuilding, ordnance, nuclear energy, etc., the production capacity is not enough to support the production of this type of aircraft.

Of course some people will say that McDonnell Douglas 80 and McDonnell Douglas 90 are aircraft of this level. Didn’t they mean that they have been domestically produced?

It is localized, but this kind of localization requires quotation marks, because most of the core parts of the 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, there are still many shortcomings in the country to complete the manufacture of large aircraft. For example, the single-aisle wide-body airliner designed by Ascendas Group uses 35% of composite materials, of which there are two cabins. The segment and foot wings need to be molded with carbon fiber composite materials at one time.

The problem is that Ascendas Group’s ideas are good, but there is no large-scale hot pressure irrigation of more than ten meters and large-scale laser spraying equipment that can realize multi-position spraying and weaving carbon fiber in China.

Japan and the United States even have such equipment~www.readwn.com~ The problem is that people don’t sell it for much money, don’t you say, even the foundry is too lazy to do it for you, the reason is very simple, your Ascendas Group can guarantee the continuity of half a year Purchase? If not, where to cool down, where to take it with you.

This is the large aircraft ceiling often referred to in the aviation industry.

Regardless of the same aircraft, but those who can enter the field of large aircraft are the real entrance. The problem is that there are very few such companies and countries. Don't they want to?

No, the threshold is really too high, and the faces involved are too big to be able to board at all.

Ascendas Group naturally encountered this opaque ceiling, and it was even more isolated and helpless than other similar companies. At this time, it is out of fashion to go down. What should we do if this is the case?

The Russian aviation industry led by Djokovic made a mighty visit to China. Since it is a cooperation, naturally you can’t just make a profit. You don’t have anything in the country?

At least some blood should be released, otherwise those Davaris, Hara Shao, Ullah~~ Don't all shout for nothing!
