Aerodynamic performance of the DeSiReH high-lift laminar wing at free flight and ETW in-tunnel conditions
Central Aerohydrodynamic Institute (TsAGI) 1 Zhukovsky Str., Zhukovsky, Moscow Region 140180, Russia
The current research concerns a half-model high-lift configuration inside the European Transonic Wind Tunnel (ETW) at landing regime. The influence of the wind-tunnel walls (both slotted and closed) is investigated and the numerical results are compared with measured data. The investigated model is a three-element landing configuration with Krueger device and flap. All calculations are performed on structured grids using EWT-TsAGI code. The computed in-tunnel results are in good agreement with uncorrected experimental data, with maximum lift predicted at the same angle of attack. The slotted wall configuration produces less wall interference than the closed wall configuration.
