Results of an improved version of LTRAN2 for computing unsteady airloads on airfoils oscillating in transonic flow

Paper presented at AIAA 12th Fluid and Plasma Dynamics Conference held in Williamsburg, Virginia, 23-26 July 1979. Using an improved version of the NASA Ames code LTRAN2, unsteady airloads were computed for a flat plate and a lifting transonic NACA 6k A006 airfoil, for harmonic pitch and control surface motions at reduced frequencies based on serai-chord 0 lifting surface theory becomes an increasingly useful alternative.
