Discussed in this paper are some of the results in Design Aerodynamics research for civil transport aircraft. An iterative inverse-direct design software has been upgraded. The design modification of a supercritical wing has been conducted. DTE wing concept is investigated numerically and experimentally. GA approach provides optimized positions for the high-lift system. The NS analysis of the after-bodies helps to validate the engineering method and its software developed in this work.
