For the tests in the large low-speed facility (LLF) of the German-Dutch Wind Tunnels (DNW), researchers used the META multiple swashplates, developed and patented by DLR, in order to adjust the rotor blades’ angle of attack multiple times during each rotor revolution, thus actively impacting the noise and vibration generation of the helicopter.
