Available in PDF, EPUB and Kindle. Book excerpt: The inviscid transonic flow over an NACA 64A410 airfoil oscillating in pitch in a Mach 0.72 stream was calculated with a program based on the unsteady Euler equations. The airfoil oscillates about a mid-chord axis with attitude alpha = 1 deg + or - 1 deg at reduced frequency k = omega C/U(infinty) = 0.2. The effects of two approximations made in the analysis, handling of boundary conditions at the airfoil surface and at the perimeter of the computation field, have been studied. (Author).
