The so-called domestic aviation engine has achieved a major breakthrough, which refers to the technological breakthrough of the CJ-1000 engine. As a supporting research and development project for the domestic large aircraft C919, the CJ-1000 was established very early. After years of research and development, the CJ-1000A has continued to make technological breakthroughs. I think the biggest breakthrough is the breakthrough in blade material technology.
For aeroengines, blades are the core of the core, because the blades have to withstand baking at hundreds of degrees for a long time and still operate normally and remain stable. Ordinary materials are simply not qualified. , which is also one of the key technologies that restricts the progress of my country’s aerospace engine research and development.
Some netizens may not understand this. After all, there are already some mature aviation engines in the world. By directly importing these engines, wouldn’t the cost be better than our own research and development? Why should we break the technological monopoly of developed countries?
What I want to say here is that any time the core technology is in the hands of others, it is ultimately an unstable factor.
Our country is a major aviation consumer. It buys a lot of aircraft from Airbus and Boeing every year. Now our country’s domestically produced large aircraft C919 has been successfully developed and will be mass-produced soon. However, the engine currently equipped on the C919 does not It is not a domestically produced engine, but a universal CFM LEAP-1C engine, so the current power system of the C919 is designed around the CFM LEAP-1C.
Although the company that produces this engine is a joint venture between General Electric of the United States and Safran Aero Engines of France, General Motors is an American company after all, and they are actually involved in some things. Not involuntarily.
For example, in February 2020, the United States considered immediately stopping providing engines to my country's C919. Although the United States later did not do so, General Motors could still continue to provide engines to my country, but this move made the C919 Breaking into a cold sweat.
As we mentioned earlier, the current power system of the C919 is basically designed around General Motors’ CFM LEAP-1C. If General suddenly stops providing this engine in the future, then the power system of the C919 will be To start over and redesign.
Although in the long run, even if GM stops the supply of CFM LEAP-1C, it will not have much impact on the C919. With the continuous development of the CJ-1000 engine, the C919 also has Plan B. However, this will extend the mass production time of the C919. You must know that there are currently more than 800 orders for the C919, and these orders will be delivered within the next few years. If the order cannot be delivered normally due to engine problems , then C919 will undoubtedly lose many customers.
In addition, in the long run, we cannot always rely on others for core technology. This is tantamount to leaving our destiny to others. I believe some mobile phone manufacturers are deeply aware of this. . We cannot leave our fate to others
Since 2019, Huawei has been subject to restrictions from Country M, and the restrictions have been continuously escalated. All chip manufacturers related to Huawei cannot provide Huawei with chips. As a result, although Huawei It has very strong chip design capabilities and can design 5-nanometer or even 3-nanometer chips. However, no foundry is willing to help them produce the designed chips. Therefore, Huawei's mobile phone business has undergone great changes due to the cutoff in chip supply. Among them, Honor has separated from Huawei. In addition, the scale of Huawei's existing mobile phone business is also constantly shrinking. Once the storage chips are used up in the future, Huawei will face the embarrassment of having no cores available.
Of course, in addition to Huawei, many companies in our country are currently included in the entity list of country M. These companies cannot normally purchase technology or equipment from country M or other countries. Both research and development and production have been greatly affected.
These experiences are bloody lessons. If we take the relevant core technologies into our own hands, we will not let others do whatever they want, and we will have a stronger initiative in dealing with many things. Because of this, even if there are many difficulties and even if the technology is very difficult, we still have to spend a lot of effort to overcome our country's aero-engine technical problems. Because this is not only related to the normal production and research and development of C919, but also related to the technical safety issues in my country's civil aviation field.
