DLR in-flight demo proves active blade twisting cuts main-rotor noise and vibration
DLR-led researchers have demonstrated in-flight active twisting of helicopter main rotor blades, showing significant reductions in noise and vibration while improving rotor performance. The STAR project’s in‑flight proof-of-concept paves a technical path toward quieter rotorcraft and supports urban air mobility noise-reduction goals.
