Webb21 juni 2024 · To verify the suitability of the actuator, the pitch actuation system dynamics were modeled in Simulink. The maximum continuous pitch rate is 550 ∘ s −1 . Considering that the timescale factor between the G06 and the full-scale reference is n t ≈ 1 / 240 , this corresponds to a full-scale pitch rate of approximately 2.3 ∘ s −1 . Webbsensors and actuators. Load alleviation can be achieved using for example blade pitch or ﬂap actuation in combination with diﬀerent types of sensory systems. In this study, the focus is on pitch actuation. Modern, industry standard, load alleviation control schemes include cyclic blade pitching based on blade root bending moment measurements. lightweight hay elevator
