The synergistic use of passive (by bend-twist coupling) and active (by individual blade pitch control) load mitigation is considered in this work. It is found that while both contribute to load reduction, they have opposite effects on the actuator duty cycle, and this induces an additional unexpected pay-off from the combination of these two technologies.

Abstract
The synergistic use of passive (by bend-twist coupling) and active (by individual blade pitch control) load mitigation is considered in this work. It is found that while both contribute to load reduction, they have opposite effects on the actuator duty cycle, and this induces an additional unexpected pay-off from the combination of these two technologies.File in questo prodotto:
