Booster stages in aviation gas turbines refer to low-pressure compressor stages that increase air pressure before it enters high-pressure compressor stages. These stages are crucial for enhancing overall engine efficiency, particularly in turbofan designs. The discussion highlights the relationship between fan and booster stages, noting that both can be driven by a single low-pressure turbine. However, due to the speed differences between the low-pressure compressor and the fan, a gearbox may be necessary to synchronize their rotational speeds. Understanding the role of booster stages is essential for effective gas turbine design.
