Abstract

This paper presents an investigation of an actively controllable camber variation for rotor blades. The new structural Concept described here is based upon a 3-cell blade design using tension-torsion-coupling together with piezoelectric stack-actuators to bend the cross-section about the blade axis. A finite-element-model of an adaptive camber rotor blade is used to perform a parameter optimisation to maximise camber variation at the blade tip. Both, geometric as well as material and manufacturing parameters are evaluated. Their influence is presented.
