The evolution of the aerodynamic design tools and transport aircraft wings at Embraer

摘要

This paper provides a historical summary of the aerodynamic design of transport aircraft wings during the past 35 years at Empresa Brasileira de Aeronáutica (EMBRAER) and describes, from the application standpoint, the evolution of the theoretical and experimental techniques and tools used. Beginning with the EMB110 Bandeirante and proceeding with the EMB121 Xingu, the EMB120 Brasilia, CBA123 Vector, ERJ145 family and now with the EMBRAER 170 family, there has been a progressive shift from empirical and simplified analytical design techniques to CFD methods of ever increasing capabilities. In the experimental field, more advanced windtunnel test facilities and techniques have also been progressively employed to match the increased complexity of the computational methods.
