The possibility has been studied of using modern CFD (CFD - Computational Fluid Dynamics) software package for solving problems of designing wings seaplanes. The description of the physical-mathematical model and the algorithm for solving the problem based on the Reynolds averaged Navier-Stokes equations are given. The analysis is given of application of several turbulence models: Spalart-Allmaras, three different modification models and standard model, under which has been selected the most appropriate model, which gives the best result of calculations with experimental data. Testing of the methodology used and the software have confirmed the validity of the results. The results of series of numerical studies of typical configurations of the wing with float on the end wing are presented. The effect is studied of several variants of the deviations of the wing and the location of the end floats on the values of the total aerodynamic coefficients of forces and moments acting on the seaplane wing.
