| High-Pressure Compressor Spacer Disc | In718 | Φ669*111 | 128 |
| High-Pressure Compressor Stage 3 Disc | In718 | Φ680*120 | 212 |
In aircraft gas turbines, Stage 1 Disc, Stage 2 Disc and Stage 4 Disc usually refer to different levels of compressor or turbine discs, and these discs play a specific role in different stages of the compressor or turbine.
- First-stage disc: Its function is to compress air or convert the energy of combustion gas, and its characteristic is to handle large air flow or high-temperature and high-pressure gas.
- Second-stage disc: Its function is to further compress air or convert energy, and its characteristic is to withstand medium pressure and load.
- Fourth-stage disc: Its function is to perform the final stage of compression or energy extraction, and its characteristic is to withstand the highest pressure and temperature.
