How many stages does the N2 compressor consist of?

The N2 compressor in the CRJ550 is a critical component of the engine's overall performance. It is a multi-stage axial compressor designed to increase the pressure of the airflow entering the combustion section of the engine. Specifically, the N2 compressor consists of ten stages. This multi-stage configuration allows for efficient air compression, leading to improved engine performance, fuel efficiency, and thrust generation.

The design of having ten stages achieves a balance between size, weight, and efficiency, enabling the engine to produce the necessary power while maintaining operational reliability. Each stage of the compressor serves to progressively compress the air, enhancing the pressure and ensuring optimal conditions for combustion. Understanding the number of stages and their function helps in comprehending the operation of the engine and its overall efficiency in flight.
