The paper presents the results of an investigation of the flow around a half-model of a passenger aircraft and its components in T-128 wind tunnel test section with perforated walls with the help of numerical solutions of the Reynolds-averaged Navier-Stokes (RANS) equations. Cases of limitless flow in the presence of a peniche and without it were considered. To configure the peniche without a flow-through between the symmetry plane and the half-model, several options for the peniche height were considered. Its optimum height was determined based on the analysis of the obtained results. Simulation of the flow around a half-fuselage with gas flow-through under the peniche was carried out. Corrections to the coefficients of aerodynamic load acting on the half-fuselage were obtained. Comparison of the test results for an alone configuration fuselage and a half-fuselage without corrections and with the obtained computed correction is presented.
