SENECA (LTO noiSe and EmissioNs of supErsoniC Aircraft) project aims to provide a basis for decision making of environmentally friendly supersonic aircraft design taken into account the detailed modelling of the emission indexes and the local/global environmental impacts. Emission indices of NOx have been calculated for supersonic airliner M1.8 throughout the supersonic mission profile for the 2000 and 4000 nmi ranges. The EINOx calculation results correlate well between the two methods considered (BFFM2, P3T3) for the take-off and climb subsonic conditions. The difference between BFFM2 and P3T3 was found in the climb and cruise supersonic conditions. The observed difference is due to the fact that BFFM2 (the version used) does not include correction factors for pressure (kp) and temperature (kt) as a function of Mach number, which is quite important for the supersonic case. The calculation results of hourly concentration for airport fleet with contribution of supersonic airline M1.8 (through large aircraft group) demonstrates the similar levels of NOx and twice less of CO in comparison with baseline airport fleet. (Concorde is as reference aircraft for large aircraft group.)

摘要

SENECA (LTO noiSe and EmissioNs of supErsoniC Aircraft) project aims to provide a basis for decision making of environmentally friendly supersonic aircraft design taken into account the detailed modelling of the emission indexes and the local/global environmental impacts. Emission indices of NOx have been calculated for supersonic airliner M1.8 throughout the supersonic mission profile for the 2000 and 4000 nmi ranges. The EINOx calculation results correlate well between the two methods considered (BFFM2, P3T3) for the take-off and climb subsonic conditions. The difference between BFFM2 and P3T3 was found in the climb and cruise supersonic conditions. The observed difference is due to the fact that BFFM2 (the version used) does not include correction factors for pressure (kp) and temperature (kt) as a function of Mach number, which is quite important for the supersonic case. The calculation results of hourly concentration for airport fleet with contribution of supersonic airline M1.8 (through large aircraft group) demonstrates the similar levels of NOx and twice less of CO in comparison with baseline airport fleet.
