Emission Comparison of Turbofan and Open Rotor Engines under Special Consideration of Aircraft and Mission Design Aspects

摘要

An integrated parametric model involving the design of propulsion system, airframe and flight mission is presented. Based hereon, the CO2 emission characteristics of advanced conventional turbofan-powered aircraft and open rotor-powered aircraft are analysed against essential aircraft and propulsion system design parameters. In addition, first concept-specific trend statements on Nox as well as propulsor noise emission characteristics are derived. The obtained results may contribute to a better understanding of optimum aircraft design conditions for advanced system architectures.
