ABSTRACT
Since day one of the gas turbine engine, the compressor was the key component for success and always required high development efforts and costs. The importance of the compressor for modern high bypass ratio engines is demonstrated by the fact that 50%–60% of the engine length, up to 40%–50% of the weight, 35%–40% of the manufacturing costs, and 30% of the maintenance costs are taken up by the compression system. The advances in compressors allow aeroengines to operate with core engine thermal efficiency in the range of 50% while the propulsive efficiency approaches 80% [1].
