The “compressor rotational speed” in aircraft design refers to the speed at which the compressor rotor or impeller rotates. This parameter is a crucial factor in determining the performance and efficiency of the compressor and, consequently, the entire aircraft engine.
Formula for Compressor Rotational Speed:The formula to calculate the compressor rotational speed is straightforward:
- Rotational Speed (N) is the compressor rotational speed, typically measured in revolutions per minute (RPM).
- Engine Shaft Speed (RPM) is the speed at which the engine’s main shaft or rotor turns.
