Where are all the parts eliminated from civil airliners?
posted the : 2024-05-17
The service life of civil airliners is usually long, but with the passage of time, these airliners will eventually reach their service life due to technological progress, increased operating costs or decreased safety and comfort. When an aircraft is retired, the whereabouts of its parts mainly include the following situations:
1. ** Converted into a cargo plane * *: Some retired civil aviation passengers will be converted into cargo planes to continue to use. Because the service life of passenger planes is usually shorter than the actual life of aircraft, some retired passenger planes can still be put into operation as cargo planes after modification.
2. ** Disassembly and reuse * *: The most valuable components on an airplane include engine, landing gear and electronic equipment. After renovation, these components can re-enter the market as aviation components. Each aircraft can disassemble about 50,000 large parts, and nearly 95% of the materials in the whole engine can be recycled.
3. ** Auction sale * *: Some airlines or airports will sell the whole machine or parts of retired aircraft by auction. For example, Kenya's Airport Authority has announced that it will hold an auction to sell 92 old aircraft stored in four domestic airports, including various types from Ukrainian An-24 to Boeing 737.
4. ** Recycling * *: For parts that can no longer be used or have special treatment needs, professional disassembly and recycling may be carried out. This helps to reduce environmental pollution, and at the same time, it can also recycle metal materials, such as aluminum and titanium.
5. ** Donate education * *: Sometimes, retired aircraft or their parts will be donated to educational institutions for aerospace education or exhibition purposes.
6. ** Scrapping treatment * *: For those parts that can no longer be used, it may be scrapped according to environmental protection standards.
To sum up, the whereabouts of domestic eliminated civil airliner parts are similar, and the above-mentioned different treatment methods will be adopted according to the actual situation and market demand of the aircraft. These treatments not only contribute to the recycling of resources, but also conform to the concept of sustainable development. For aviation enthusiasts, knowing this information can increase their knowledge and understanding of the aviation industry.
