Multi-Level Design Space for the Aircraft Exposure Assessment on Environment by Concerting Vehicle-Airport-Fleet Operational Scenarios

Abstract

A multi-discipline design optimization approach is used by aircraft manufacturers to provide the necessary aircraft performances at conceptual design stage. The concept of the reference aircraft is fundamental to show the achievements in baseline aircraft design, their efficiency to solve the environmental problems. Aircraft noise(AN), engine emission and fuel consumption reduction at source by new technology implementation in aircraft design is a strategic element of the environment protectionmanagementin aviation sector, their stepwise development provides closer distances of the protection zone’s boundaries between the runways/flight paths and residential areas in vicinity of the airport. In grounding the necessary noise reduction technology for baseline aircraft design its acoustic efficiency should be assessed for appropriate AN standard limits in accordance with ICAO certification procedures, for the single flight event at departure/arrival stages in airport, in overall airport traffic scenario and at least regionally/globally. All of them must show that AN exposure continues to be the not-growing and ICAO Balanced Approach is still feasible for effective AN exposure and impact management. For fuel burn and aircraft engine emission besides the certification requirements the net-zero CO2emission for the air traffic should be confirmed. The approach to coordinate the multi-factor exposure assessment at Vehicle-Airport-Fleet scenarios is presented and recommended for the usage in effective implementation of the reduction technologies in aircraft designs. The approach starts at new aircraft design stage, but it is fully connected with expected operational and maintenance performances influencing the exposure levels on environment
