An Approach to Subsonic, Turbulent Flow Airfoil Design Using Mini-Computers 770479

An airfoil design method has been developed which, with the aid of a mini-computer, can be used to determine the velocity distributions that will produce desired design parameters (lift, drag, and pitching moment) at the design condition and test for boundary layer separation. Use of a generalized equation for the velocity allows the design parameters to be determined as a function of coefficients of an integrated expression. Therefore, any series of general velocity distributions can be analyzed and the best one for the design mission selected.
