Advanced aerodynamics is the study of airflow around and within an object, such as an airplane, and how the air interacts with the object. It involves analysis of the forces of lift and drag, as well as the effects of air pressure, temperature and viscosity on the object. It also addresses the aerodynamic performance of a design, such as its efficiency, stability, and maneuverability. Advanced aerodynamics is used to design aircraft and improve their performance, as well as to optimize the performance of existing designs.
