Introduction:
As a self-developed large jet airliner developed by China, the C919 marks an important milestone in China's civil aviation industry. However, although the C919 has begun commercial operation, most countries have not been able to replicate this achievement. This article will discuss in detail why most countries cannot build C919 from the aspects of the scarcity of global fuselage forging presses, the lack of technology and supporting industries, and restrictive policies and international competition.
The scarcity of fuselage forging presses
The fuselage forging press is the core equipment for the production of key components of large aircraft such as C919, and its importance is self-evident. However, the number of fuselage forging presses in the world is extremely limited, and it is reported that there are currently only 7 fuselage forging presses in the world, hence the name BIG7. This scarcity has led to the high price of fuselage forging presses and the extreme difficulty of manufacturing. For most countries, it is not an easy task to build a fuselage forging press, which has also become one of the key factors restricting them from manufacturing large passenger aircraft such as the C919.
Lack of technology and supporting industries
In addition to fuselage forging presses, the manufacture of large passenger aircraft also involves technical and industrial support in many fields. For example, the technology of design, materials, manufacturing, testing, etc. needs to be long-term
Accumulation and rapid innovation require high R&D and production capacity. However, most countries lack the technology and supporting industries in these areas. The lack of support from these core technologies and industrial chains makes them unable to meet the requirements of manufacturing large passenger aircraft, and thus cannot replicate China's C919 achievements.
Restrictive policies and international competition
In addition to technical and industrial issues, there are policy and competitive barriers in some countries. Some countries have set up restrictive policies that prohibit companies from other countries from entering their own markets, which has brought greater challenges to the international competition of large passenger aircraft such as the C919. In addition, some countries have relatively limited investment in the aviation industry and cannot compete with countries that invest as heavily as China. These restrictive policies and unfavorable factors of international competition have prevented most countries from reaching the level of C919.
epilogue
All in all, most countries are unable to build large passenger aircraft like the C919 mainly due to the following reasons: the scarcity of global fuselage forging presses, the lack of technology and supporting industries, and restrictive policies and international competition. Solving these problems requires long-term investment and accumulation, as well as strengthening international cooperation and openness and sharing to promote the development and innovation of the global aviation industry. Only by making breakthroughs in these areas will other countries be able to gradually catch up and achieve their goals of developing and manufacturing large passenger aircraft independently.
