Insights and lessons learned from the aerodynamic analysis of a High Wing Transport high-lift configuration are presented. Three-dimensional NavierStokes computational fluid dynamics simulations using the OVERFLOW flow solver are compared with high Reynolds-number test data obtained in the NASA Ames 12-Foot Pressure Wind Tunnel facility. Computational analysis of the baseline High Wing Transport high-lift configuration with and without externally blown flap jet effects is presented. Using the developed computational fluid dynamics analysis capability, several aerodynamic investigations, including an assessment of nacelle strake effectiveness and wake vortex prediction, are presented.
