Course
Objectives |
After this course, the student will be able to explain the fundamental characteristics of subsonic airfoils and the connection between surface pressure distributions and the lift, drag, and pitching moment generated by the airfoil. The student will be able to discuss the effect of pressure distributions on the growth of the boundary layer and the resulting viscous effects. The assignments will help the student develop an understanding of the effect of geometry characteristics of the airfoil on the aerodynamic behavior. The student will be able to use thin airfoil theory and codes such as XFOIL to analyze airfoils and discuss the results. The student will be able to design subsonic airfoils using inverse design techniques. |
