Abstract: The analysis of distribution and magnitude of viscous and total stresses arising on the surfaces of the NACA 0012 airfoil when changing the angle of attack from 15 to 40 degrees was performed in the article. It is determined that with an increase in the angle of attack, total stress acts from the peak magnitude near the leading edge to the uniform distribution of the stress magnitude over the entire upper surface of the airfoil. A gradual increase in the magnitude of total stress near the leading edge occurs on the lower surface. The maximum magnitude of viscous stress was determined at the leading and trailing edges of the airfoil at the high angles of attack.
Key words: the airfoil, the angle of attack, stress, the surface.
