Low-pressure compressor
The compressor consists of a series of bladed disks that are arranged between stators and rotate at very high speeds. Large air volumes are ingested and compressed before they are passed on into the combustion chamber. To achieve pressure ratios of over 30 in present-day engines two different types of compressors are used: low-pressure compressors and high-pressure compressors. These compressors which rotate at different speeds are driven by their counterparts in the turbine via concentric shafts.
