Abstract:The Green Rotorcraft project (part of Clean Sky JTI) is
studying the Gurney flap as a demonstrator of a smart adaptive
rotorblade. Deployment systems for the Gurney flap need to
sustain large centrifugal loads and vibrations while maintaining
precisely the displacement under aerodynamic loading. Designing
such a mechanism relies on both the actuation technology
and the link which transmits motion to the control surface. Flexible
beams and piezoelectric patch actuators have been chosen as
components to design this mechanism. Flexible beams are providing
an hinge-less robust structure onto which the piezoelectric
actuators are bonded. A candidate topology is determined
by investigating the compliance of a simple wire structure with
beam elements. A parametrized finite element model is then built
and optimized for displacement and force through surrogate optimization.
The whole process does not requires many finite element
analyses and quickly converge to an optimized mechanism.
