Abstract:

A numerical method for transonic shock-free or nearly shock-free airfoil and wing redesign based on the full potential equation is presented. The method utilizes a generalized fictitious gas approach wherein a variety of parameters controlling the character of the fictitious gas laws are introduced to provide a degree of control over the redesigned upper surface geometry and the pressure distribution of the redesigned shape. Results for a redesigned advanced airfoil as well as a three-dimensional wing are illustrated. Significantly improved aerodynamic characteristics are achieved through the present redesigned technique. Author
