Low Speed Aerodynamics
- Department of Aerospace Engineering
Low speed aerodynamics is a basic theoretical subject in Aerospace Engineering. The class is intended to familiarize students with the fundamental solutions and mathematical modeling of inviscid and viscous flow cases around aerodynamic profile, airplane wings and aircraft at low speed domain.
