Short- to medium-length airline routes require rugged engine designs. The PW2000 incorporates features to lower fuel consumption and provide superior durability and maintainability. A stiff centerline, erosion resistance of gas-path components, thermal resistance in the hot section, and FADEC control contribute to reliability and performance retention. Service experience demonstrates that the PW2000 has achieved early maturity. A product improvement plan will further increase reliability and lower operating costs.
