It is no wonder that Zhuang Jianye is so happy, unlike electron beam, laser and EDM and other punching technologies, electrochemical drilling due to the unique processing mode, so that the quality of the air film cooling holes, especially on the turbine blades, is doubled.

On this basis, the cooling technology of turbine blades has moved from traditional single cooling to more technologically advanced composite cooling, coupled with more advanced heat-resistant materials, and the power of aero engines has made a qualitative leap.

Not to mention those military engines equipped on the third-and-a-half-generation, or even fourth-generation combat aircraft (using the four-generation division method), that is, the large-bypass turbofan engines on civil aviation have also taken a big step forward by taking advantage of the flight of aero engines in the manufacturing field.

Take the Boeing 787 as an example, in the past, to promote an aircraft of this size to do a long-distance flight across continents, not to mention three aero engines, in order to achieve more stable and safe flight performance, it is not impossible to make four.

However, due to the technological leap of the aero engine, the gas temperature has been increased by one-third compared with the previous one, so that the power of the new aero engine is twice that of the old aero engine.

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 the previous four engines.

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, so the more or less aero engines directly affect the maintenance cost of the aircraft.

You must know that the plane is not a car, just enter a 4S shop and spend a few dollars to get it, if you want to maintain the aircraft, a rivet may be worth a high-end car, the cost is simply staggering.

The fundamental driving force for airlines to buy passenger aircraft is also to make money, and naturally the idea is to try to reduce the cost of post-maintenance of the aircraft.

The Boeing 787 took advantage of the dividends of the leap in aero engine technology to make the traditional four engines into two, and the flight quality and range remained the same, and the maintenance cost of the engine was reduced by half. (Just take 787 as an example, as for the quality issue, I will not comment here)

In these years, people always say that they should seize the opportunity, stand on the tuyere, grasp that even pigs can fly, if this theory is put on the aero engine, the new generation of aviation engine manufacturing equipment represented by the electrochemical punch machine is gradually mature and widely used is the biggest outlet.

As long as you can grasp it, not to mention overtaking in corners, Tengfei factory can at least make a usable gas turbine power unit, the worst of all, deep cultivation of key processing technology in aviation engine spare parts, for other aviation development giants to do support, that can also live a very moist life.

So not only does this have to be done, but it also has to be done as soon as possible.

As for Tengfei Factory's use of other people's Japanese technology to light up its own science and technology tree, after the results come out, whether the Japanese will come to find the back account, Zhuang Jianye is not worried at all.

If nothing else, just look at the chattering and unserious attitude of the Japanese Mitsubishi Group in these materials, and you will know that Company H has made a bunch of things that benefit without cost.

It is full of expectations, blueprints and even fantasy things, it is obvious that the Japanese Mitsubishi company cast a wide net to catch more fish, anyway, no one can figure out where the future technology path is, and raising so many technicians can not let them eat rice, just let them do it according to their own ideas, can become Japan Mitsubishi from the technical level to the next level, make a lot of money.

If it can't be done, it's nothing, continue in a different direction.

All in all, Japan's Mitsubishi is very much like an antique dealer in Panjiayuan, throwing money everywhere, collecting everywhere, as long as there is a Mengzhong, it will be profitable.

Obviously, the pile of H company is a hodgepodge of Mitsubishi in Japan, even if the experienced people are dizzy after reading it, they are not sure which is the key technology in the future.

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

The problem is that if you do this, let alone the Tengfei factory, the whole country can't afford it.

Fortunately, Zhuang Jianye is a person who has lived for two lifetimes, and those eyes are like the big shopkeeper who is used to touching antiques, and you can see at a glance whether your thing is an old object or a modern imitation.

But even so, Zhuang Jianye only picked out three useful ones from more than forty techniques, which shows that the technology tree is not so easy to climb, and it is possible to run to other branches if you are not careful.

Of course, Company H didn't have any good intentions, giving you so many so-called "cutting-edge" technologies of aero engines, I wish you could jump in one by one, not to mention drowning, you can be tired to death.

In this regard, Zhuang Jianye felt that Company H was very good, and if there was an opportunity to let Company H pit a few more times, Zhuang Jianye would be absolutely willing and did not hesitate at all.

In a happy mood, he sorted out the three useful information, threw the rest aside, and then rubbed his swollen temples, then picked up the phone and said with a smile: "Director Guo, I'm Xiaozhuang, can you help me contact me about what you told me a few days ago?"

......

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

As the ministry of the year to set up a capable machinery and equipment factory, the zero degree factory can be described as the peak of the debut, in the seventies to build a factory, and then undertake the production and manufacturing of EDM punching equipment, and so on after several years of efforts, the completion of the EDM punching equipment by the ministry and the state acceptance, after delivery, the zero degree factory has received numerous praises.

I thought that by taking this opportunity, the Zero Plant could become a supporting supplier of precision machining equipment for various aero engine manufacturers.

With the shutdown of the "Spey" engine, the turbofan 6 was struggling, and the turbojet 14 was facing foreign countries.

This made the zero degree factory very embarrassed, and there was no way for the factory director Wei Guangping to go to the ministry, hoping to give the zero degree factory some production tasks, and the ministry did not want to waste the factory that they had spent a lot of effort to build, and squeezed out some production tasks to let the zero degree factory maintain production.

But the problem is that the ministries and commissions can't give too many production tasks with great efforts, after all, the troops who make up the absolute majority have been tightening their belts, and the ministries and commissions are not having a good time.

As a result, the Zero degree Factory inevitably fell into a predicament, and the entire factory fell to the bottom, especially the technical team that was transferred back then, and people were even more panicked.

For a time, it was better to sell tea and eggs than to build missiles, and it was better to use a scalpel than to use a pig-killing knife to slip through the dust in the zero degree factory.

Some of the technicians who had access to the factory were transferred out of the zero degree plant, while others who had the audacity to simply resign from their public posts and go to the coastal areas to give it a go.

But more of it is to stay in the zero degree factory and suffer silently.

Wei Guangping didn't think of a way to get out of trouble, switch to civilian products, other factories under the ministry and commission, their zero degree factory technology and equipment are not bad, there is no reason, the result is ruthless reality has taught Wei Guangping a lesson, their zero degree factory is really not good.

Basically, it's a loss, and in the end, it's like this, with a huge backlog of things, and I can't sell them!
