Take Off My Aviation Era

This is indeed the case.

If the previous aero engine of Ascendas Group can only be used in the circle of drones and light aircrafts, then the WD-52ML turbofan engine is really considered to be in the room.

This turbofan engine with a maximum thrust of 5.2 tons is developed on the basis of the D-50 turbo gas power unit by Ascendas Group.

As the basic model of the navy's small naval gas turbine, the D-50 turbine gas power unit has been used as marine power for the navy, offshore drilling platforms and some civilian ships for so many years.

The reason why the aero engine model was not developed immediately is nothing else, because the weight of the D-50 turbine gas power unit itself is too large, and the weight of the whole machine has been maintained at about 1.5 tons.

As a ship or ground power, 1.5 tons is nothing, but it is too big for an aero engine, which seriously affects its thrust-to-weight ratio.

It’s not that Ascendas Group has never thought about reducing the weight of D-50, but after years of tossing and using many methods, the effect is still not obvious. There is no other reason, just because Ascendas Group is stuck in the difficult problem of advanced aviation engine materials.

We must know that the Ascendas Group at that time has already brought the general nickel alloy to its extreme. Although the most advanced ceramic-based, carbon-based and aluminum-titanium alloys have made progress, they have even begun small-scale applications in some places, but these cutting-edge materials are stable The performance is slightly worse, and key components such as turbine discs, transmission shafts, rotors, combustion chambers, etc., similar to aero engines cannot be applied yet. Therefore, even if Ascendas has a broad future prospect, it has to face a very realistic problem.

What should we do about the gap between traditional nickel alloys and advanced materials in the future?

The solution given by the British and American aviation powers in this regard is powdered superalloys, the most representative of which is the general-purpose Rene series materials, the famous CF-6, CF-34, CF-56, and F-110 Such materials are used in advanced aviation engines.

It is no exaggeration to say that Rene series materials are the key element of advanced aeroengines.

And Ascendas Group is almost blank in this regard, let alone Ascendas Group, even the progress of the entire domestic powder superalloys is not optimistic.

There is no way that this thing belongs to the strategic material in the strategic material, and all countries in the world treat it as a treasure.

If you can’t buy it with money, you have to do it yourself in China, but this stuff involves many disciplines such as metallurgy, materials, mechanics, and basic chemistry. The aviation powers such as the United Kingdom and the United States rely on more than a hundred years of old foundation and gather top talents from all over the world. The results achieved, the modernization process is less than half a century old, how can the whole country be compared with domestic food and clothing?

It is based on this reality that the second-generation core aircraft of Ascendas Group will set a development goal of more than ten years. There is no way, and the powder superalloy technology cannot be solved in a short time. Even if it is solved, it will lag behind the aviation powers such as the United Kingdom and the United States. It can only aim at the third-generation aero-engine materials, and achieve curve overtaking as much as possible.

Based on various practical problems, the position of the D-50 turbo gas power unit within the Ascendas Group is actually very embarrassing. Originally, Ascendas Group hoped that the only gas power unit that can reach 4000 kilowatts in the Ascendas Group can quickly take shape and make it take off. The next step of the Group's Costin plan can continue to advance, so that the opportunity window for the replacement of domestic and foreign regional passenger aircraft from the mid-1990s to the beginning of the new century will obtain the expected huge benefits.

Due to the material difficulties, the D-50 turbo gas power plant is the same as the second-generation core on the road to the realization of aero engines. That is a difficult step.

There is no way that Ascendas Group can only look at foreign countries, hoping to solve this problem by introducing medium-thrust engines. After all, there are few opportunities for the replacement of regional passenger aircraft in a lifetime. Since it can run into it, it can't be let go.

The problem is that the introduction of engines can solve the problem, but the relevant manufacturers also have many restrictions on Ascendas Group. For example, Pratt & Whitney requires that the regional aircraft with Pratt & Whitney engines produced by Ascendas Group must obtain European and American airworthiness certificates, otherwise they will never not for sell.

Because Pratt & Whitney is not sure whether Ascendas Costin's regional jets meet aviation safety standards, it is afraid that they will frequently drop the aircraft when they are sold.

The Rolls-Royce company in the United Kingdom is a bit better and not so demanding, but it requires that the Ascendas Group's regional passenger jets equipped with Rolls-Royce engines can only be sold in East Asia and Southeast Asia. It is best not to interfere in other places, because Rolls-Royce is in Brazil and Canada. The aviation companies that take it all have shares, and Rolls-Royce does not want competition between them and affect the proportion of Rolls-Royce engines.

As for GM, it didn't even pay attention to the Ascendas Group, so why sell the engine to you? There are so many aerospace manufacturing companies that GM has a share in, and its own people are still too busy, so there is no time to take care of outsiders?

The world’s three major aero-engine manufacturers have different attitudes, but one of them is the same as agreed, that is, the regional airliners equipped with their aero-engines can only be used in the civilian field and must not be used for military purposes. Stop maintenance of aircraft engines and supply of spare parts.

The reason why Ascendas Group has been able to stagger over the years until now is that it has been walking on two legs. If the military field is missing, it is equivalent to cutting off a leg of Ascendas Group. If the domestic aviation market has matured, it’s okay. The problem is now. The domestic aviation market can only be said to be about to start, and it cannot support aviation manufacturers like Ascendas Group.

Therefore, Ascendas Group is very entangled in the introduction of engines. The introduction will be put on a tight curse. It is estimated that it will be difficult to remove it in a lifetime. If it is not introduced, will it be necessary to watch the huge market opportunity pass by?

Just when Ascendas Group was troubled with how to make a decision~www.readwn.com~Aerospace Materials Research Institute suddenly received a piece of good news that made Ascendas Group up and down. The research institute led the nickel-based powder superalloys and achieved a breakthrough and succeeded. Beyond the first generation of powdered superalloys, the second generation of powdered superalloys was prepared. After testing, its performance is no less than that of GM's Rene80 material.

When the news was announced in the industry, other aviation companies were just stunned, and then the praise should be praised, and the congratulations should be congratulated. Only Ascendas Group moved quickly and took 10 million yuan to provide the second-generation powder superalloy technology patent together. Two metal metallurgical technology experts from the Institute of Aeronautical Materials dug together to Tengfei Group.

In fact, at the time, Zhuang Jianye was targeting a former Soviet material expert who worked for the Institute of Aeronautical Materials. The reason why the institute was able to achieve breakthroughs in powder superalloy technology from scratch and across generations was inseparable from this Technical guidance by experts from the former Soviet Union.

As a result, the Institute of Aeronautical Materials did not care about protecting the calf. Even the headquarters and ministries and commissions greeted the Ascendas Group. Zhuang Jianye saw that the master couldn’t dig out his students, so the Ascendas Group used its “money capability” to form it out of thin air. He started his own high-temperature metal powder research team and quickly achieved breakthroughs, producing nickel-based high-temperature metal powder turbine disks and nickel-based alloy single crystal turbine blades.
