1. booster compressor
LP (low pressure) compressors in turbines are sometimes referred to as booster compressors.
The task of this compressor is to ingest air and compress it before it is fed into the combustor. Advanced engines have both a low-pressure and a high-pressure compressor. Also known as a booster, the low-pressure compressor is responsible for precompressing the air. Developing the technology to extend the operating range and manufacturing the blades out of composite materials to reduce the overall weight will deliver further improvements.
The low-pressure compressor of the EJ200, the Eurofighter's engine, is the first compressor with a blisk design ever to go into production. MTU developed linear friction welding at that time specifically for manufacturing the blisks.
