In this work, the research results are presented highlighting the influence of the spar structure on a helicopter SMART rotor blade stress-strain state, taking into account the operational and control loads, geometry features, reinforcement scheme and the composite material structure. To describe the mechanical behavior of a model SMART blade, it was proposed to use a coupled piezoelectroelastic setting that takes into account the forward and reverse piezoelectric effect occurring in piezoelectric actuators. Evaluation of a SMART controlled blade strength with a C- and D-shaped spars was carried out.
