The Deep Thermal Convection Problem,e it is justified to date the beginnings of German aeronautical research to .. He was the first, who enquired scientifically why a bird flies. This shall not belittle the preceding work, on the contrary. It is, with its early experiments, important. Its failure is due to the fact that systematic “re

Mixed Convection in Multicomponent Systems, as performed by Ludwig Prandtl in Göttingen. Ludwig Prandtl is called the “Father of Aerodynamics” , which does, however, not allow the conclusion that Germany is the sole “Fatherland of Aerodynamics”. Prandtl (1875–1953) is in line with other, mostly European, researchers and engineers, who

It was no coincidence that the first thorough theoretical investigations of the characteristics of aircraft during flight dealt indirectly (F.W. Lanchester )

But also in many technical fields significant aeroelastic phenomena happen in numerous forms such as the wind-induced flutter of towers, masts and bridges, t
