Civil Aircraft Conceptual Design for CO2and NOxEmission Reduction

Abstract

With the rapid development of the air transport industry and the continuous increase of fuel consumption, the environmental problems caused by the emission of civil aircraft have been paid more attention by public. In the future, the aircraft with global market competitiveness should not only meet the indicators of economy and reliability, but also consider the requirements of environmental protection, especially the negative impact of CO2 and NOX emissions. In this research, an assessment model of aircraft emissions is established to calculate the impact of CO2 and NOX emissions on global temperature changes. Further, an optimization framework for aircraft conceptual design is established combined with the analysis models of traditional disciplines such as aerodynamics and cost. Then, aiming at the low emission of the aircraft under the condition of satisfying the performance constraints, objective optimization design studies are conduct, and the design parameter could be valuable reference for the aircraft preliminary design.
