MAE 561 Wing Theory
3 Credit Hours
Fundamentals of subsonic flow over finite wings. Analysis methods and design considerations for finite wings. Detailed development of lifting-line theory and discrete-vortex Weissinger's method for high aspect ratio wings of arbitrary platform. Overview of vortex-lattice methods and panel methods. Discussion of Munk's theorems and their use in determining optimum downwash and lift distributions for multiple and non-planar wings. Design issues for winglets, tailless, aft-tail, and canard-configured aircraft. Introduction to propeller theory.
Undergraduate course in aerodynamics or fluid mechanics or consent of instructor.
After this course, the student will be able to explain the primary features of flow over finite wings and explain the typical methods of analysis for finite-wing aerodynamics. The student will be able to use analysis techniques and design methods in determining and discussing design issues associated with different wing planforms and configurations.
