    No wonder Zhuang Jianye is so happy. Different from electron beam, laser and electric spark drilling technologies, electrochemical drilling has a unique processing mode that makes the quality of film cooling holes, especially those on turbine blades, improve.  times improved.

    Based on this, the cooling technology of turbine blades has moved from traditional single cooling to more technologically advanced compound cooling. Coupled with more advanced heat-resistant materials, the power of aeroengines has made a qualitative leap.

    Not to mention the military engines equipped on third-and-a-half-generation or even fourth-generation combat aircraft (using the four-generation classification method), they are the high-bypass-ratio turbofan engines used in civil aviation. Through the advancement of aero-engines in the manufacturing field,  I also took a big step forward.

    Take the Boeing 787 as an example. In the past, to propel an aircraft of this size for intercontinental long-distance flights, at least three aero-engines were needed. To make the flight performance more stable and safer, it would not be feasible to make four engines.  impossible.

    However, due to the technological advancement of aero engines, the gas temperature has increased by one-third compared with the past, making the new aero engines twice as powerful as the previous old aero engines.

    ¡°In this way, a large wide-body passenger aircraft of the size of the Boeing 787 only needs two aero engines to achieve the effect of four engines in the past.

    Don't underestimate the reduction in the number of engines. There is a deep cost logic in this, because whether it is old or new, the principle of ground maintenance will not change. Therefore, the number of aviation engines will directly affect the maintenance of the aircraft.  cost.

    You must know that an airplane is not a car. You can just go to a 4S shop and spend a few bucks to get it done. If you want to maintain an airplane, replacing a rivet may be worth a high-end car. The cost is simply staggering.

    ¡°The fundamental driving force for airlines to purchase passenger aircraft is to make money, and naturally they are trying to reduce the later maintenance costs of the aircraft.

    The Boeing 787 has taken advantage of the leap in aviation engine technology to replace the traditional four engines with two. While the flight quality and range remain unchanged, the maintenance cost of the engine has been reduced by half. Major airlines have  Naturally, they are flocking to it, and it is difficult not to become a hit.  (I¡¯m just taking 787 as an example. As for quality issues, I won¡¯t comment here)

    These days, people always say that they should seize the opportunity, stand at the forefront, and grasp that even pigs can fly. If this theory is applied to aeroengines, the new generation of aerospace engines represented by electrochemical drilling machines will  The gradual maturity and widespread application of manufacturing equipment is the biggest outlet.

    As long as it can grasp it, let alone overtaking in corners, Tengfei Factory can at least make a usable gas turbine power unit. At the worst, it can deeply develop key processing technologies in aerospace engine spare parts to provide supporting equipment for other aerospace engine giants.  , you can live a very nourishing life.

    So not only must this be done, but it must be done as soon as possible.

    As for Tengfei Factory using Japanese technology to light up its own technology tree, Zhuang Jianye is not worried at all whether the Japanese will come to look after the results after the results are released.

    If you don¡¯t say anything else, you can tell by looking at the unruly attitude in these documents from Japan¡¯s Mitsubishi Group that Company H has come up with a bunch of things that are free of charge.

    It is full of predictions, blueprints and even fantasies. It is obviously the result of Japan's Mitsubishi Corporation casting a wide net to catch more fish. No one can be sure where the future technical path will be, and even with so many technical personnel, it cannot be allowed to do so.  If they are free of charge, just let them do it according to their own ideas, which will help Japan's Mitsubishi to move to a higher level technically and make a lot of money.

    If it doesn¡¯t work, it doesn¡¯t matter. Just continue in another direction.

    ¡°In short, what Japan¡¯s Mitsubishi does is very much like the antique dealers in Panjiayuan. They throw money everywhere and collect everywhere. As long as one of them gets caught, they will make a lot of money.

    ¡°Obviously, what H Company has done is just a hodgepodge collected by Japan¡¯s Mitsubishi everywhere. Even experienced people will be confused after reading it, and they are not sure which one is the key technology of the future.

    If you want to be sure, the best way is to hire a bunch of technical experts like Japan's Mitsubishi and spend a lot of money to try them one by one.

    The problem is that if we do this, let alone Tengfei Factory, the entire country cannot afford it.

    Fortunately, Zhuang Jianye is a man who has lived two lifetimes, and his eyes are like those of a big shopkeeper who is used to touching antiques. He can tell whether your items are old or modern high imitations at a glance.

    But even so, Zhuang Jianye only picked out these three useful technologies from more than forty technologies. It can be seen that the technology tree is not so easy to climb. If you are not careful, you may end up on other tree branches.

    Of course, H company has no good intentions. It gives you so many so-called "cutting-edge" technologies of aero-engines, and it's tempting for you to jump in one after another, not to mention drowning, it's tiring?So exhausted.

    In this regard, Zhuang Jianye thinks that Company H is very good. If he has the opportunity to trick Company H a few more times, Zhuang Jianye will definitely be willing to do so without any hesitation.

    In a happy mood, he sorted out three useful information, threw the rest aside, then rubbed his swollen temples, then picked up the phone and waited for the call to be connected. He said with a smile: "Director Guo, I am Xiao  Zhuang, can you help me contact you about what you told me a few days ago?"

    ¡­¡­

    At the same time, in the Zero Factory not far from the Flight Machinery Research Institute, the director Wei Guangping looked at the backlog of electric fans, pressure cookers, electric frying spoons, washing machines and other products and scratched his hair anxiously.

    As a mechanical equipment and instrument factory established by the ministries and commissions at that time, Zero Degree Factory can be said to be at its peak when it debuted. The factory was built in the mid-1970s, and then it was responsible for the production and manufacturing of EDM drilling equipment. After several years of hard work, the EDM drilling equipment was completed.  After acceptance by the ministries and commissions and the state, Zero Degree Factory received numerous praises after being put into use.

    I thought that by taking this opportunity, Zero Degree Factory could become a supporting supplier of precision processing equipment for various aero-engine manufacturing plants.

    With the suspension of the "Spey" engine, the turbofan 6 is struggling, and the turbojet 14 is facing foreign countries. The Zero Degree Factory, a supporting factory specially established for the professional production of aero-engine equipment, suddenly found that it had no work to do.

    This made Zero Degree Factory very embarrassed. Wei Guangping, the factory director, had no choice but to go to the ministries and commissions, hoping to give Zero Degree Factory some production tasks. The ministries and commissions did not want the factory they had spent a lot of effort to build to just sit there and go to waste, so they had to squeeze out some of it.  production tasks to allow Zero Degree Factory to maintain production.

    But the problem is that despite all the efforts of the ministries and commissions, they cannot give too many production tasks. After all, the army, which accounts for the majority, has been tightening their belts, and the ministries and commissions are not having a good time.

    So the Zero Degree Factory inevitably fell into trouble, and the entire factory fell to the bottom, especially those technical teams who were transferred back then, and they were even more panicked.

    For a time, the jingle that those who make missiles are better off selling tea eggs, and those who hold scalpels are better off holding pig-butchering knives were rife in the Zero Degree Factory.

    Some well-connected technicians have been transferred away from the Zero Degree Factory, while others have boldly resigned from their official positions and gone to coastal areas to give it a try.

    But most of them stayed in Zero Degree Factory and suffered silently.

    It's not that Wei Guangping hasn't thought of ways to get out of trouble, switch production to produce civilian products, and other factories under the ministries and commissions can do it. The technical equipment of their Zero Degree Factory is not bad, which makes no sense. As a result, the ruthless reality has taught Wei Guangping a lesson, and their Zero Degree Factory has also  It really doesn't work.

    ??Basically, whatever you do, you lose money, and it ends up like this, with a lot of stuff in the backlog that you can¡¯t even sell!
