as well as high-resolution rotor blade and fuselage aerodynamics. External measurement technologies are used to calculate noise emissions and localise noise sources, as well as to visualise the global ...

These rigs have been used to investigate aerodynamic interactions between contra-rotating rotors, optimisation of helicopter tail rotor scissors angle, blade vortex interactions, three dimensional ...

What the vortex meets the next blade ... Last year, the DLR researchers successfully visualized those rotor blade vortices by flying in front of a rocky background in the Alps, and over fields ...
