Abstract

In the given work aerodynamics characteristics calculations of flat plate profile were presented. Investigations on two calculating meshes, built with conditions, when fist site of the mesh in one cause is at the distance of h = 10^-5 of wing chord and in second cause is at the distance of h = 10^-4 of wing chord were carried out. The aerodynamic coefficients, calculated by this two meshes, are practically coincide is established.

Keywords:
