China Erzhong breaks through the fan disc preparation technology for the Yangtze River 2000 engine

The Yangtze River 2000 engine is a domestically produced power system supporting the CR929 wide-body passenger aircraft, and is the most powerful aero engine currently under development in my country. The fan disc forgings for the Yangtze River 2000 engine developed this time weigh more than 900 kilograms per piece.

After completing the development of the first part in 2019, the China Erzhong RD team continued to organize technical research, based on a large number of numerical simulation results and production experience, proposed process detail control requirements, and achieved all physical and chemical items for fan plate forgings to be qualified. It marks China Erzhong's successful breakthrough in the preparation technology of fan disc forgings for the Yangtze River 2000 engine, accumulated technical experience for the forging and heat treatment of such products, and provided assistance for the development of my country's aero-engines.
