Calculation Methods in Aerodynamics

Course objective

The students are familiar with the notion and fundamentals of aerodynamics. Building on the equations of motion for 3D wing flow the students know fundamental simplifications and mathematical and numerical methods of solution. They are able to solve problems of wing aerodynamics with these methods, and evaluate and present the results.
