The numerical simulation of the 3-d unsteady flows of incompressible fluid over bodies with complex geometry with the vortex method is considered. The vortex wake approximation is based on the Lagrange approach for the inviscid fluid. The surfaces of bodies are simulated with vortex frames. The described approach makes possible to model thin lifting surfaces as well as solid bodies. The above method was applied for numerical modeling of flow past whole body of modern medium-range passenger aircraft, calculations of aerodynamic characteristics of the aircraft. The results of calculation of pitching and side aerodynamic characteristics are compared to experimental data got in TsAGI (Central Aerohydrodynamic Institute).
