摘要

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