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

The Deep Thermal Convection Problem,ical experiments, he was able to glide in the summer of 1891, for the very first time, a distance of 30 m with his flight apparatus at moderate wind speeds. Other nations consider the beginning of aircraft engineering coincident with the first powered flight of the Wright Brothers. There are many “f

Mixed Convection in Multicomponent Systems, as performed by Ludwig Prandtl in G?ttingen. Ludwig Prandtl is called the “Father of Aerodynamics” [1, 2], 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

Jean Karl Platten,Jean Claude Legrosforeground. Another important role in the 19th century played the problem of gaining inherent stability, mainly longitudinal stability [1]. It was no coincidence that the first thorough theoretical investigations of the characteristics of aircraft during flight dealt indirectly (F.W. Lanchester [2])

Jean Karl Platten,Jean Claude Legros the surrounding airflow. Aeroelastic processes, like the swaying movement of trees, plants and oat fields in the wind, daily occur in nature. 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
