GAS TURBINE ENGINE SYSTEMS AND RELATED METHODS INVOLVING VANE-BLADE COUNT RATIOS GREATER THAN UNITY

摘要

An exemplary gas turbine engine includes a turbine section operative to impart rotational energy to a compressor section. The turbine section includes at least a low-pressure turbine and a high-pressure turbine, and a ratio of a number of stages in the low-pressure turbine to a number of stages in the high-pressure turbine is 2.
