How many stages does the N2 compressor have?

Explanation:
The number of stages in a compressor shows how many times air is incrementally compressed as it moves through the compressor. For the N2 compressor in the engine described here, the high‑pressure compressor is built with ten stages. Each stage adds a portion of the overall pressure rise and is designed to operate with the engine’s expected flow and RPM, keeping blade loading and cooling within acceptable limits. Ten stages provide the required overall pressure ratio without adding unnecessary weight or complexity. Other numbers would correspond to different engine variants, not the one used in this context.
