Experimental Aerodynamics

Share this

Experimental aerodynamics is to understand the physics of complex flow phenomena and to generate aerodynamic data for the development of advanced aerodynamic design concepts and flow models. Experimental Aerodynamics provides an up to date study of this key area of aeronautical engineering. The field has undergone significant evolution with the development of 3D techniques, data processing methods, and the conjugation of simultaneous measurements of multiple quantities.
