The present work is devoted to a numerical study of the deformation of a main rotor blade made of polymer composite materials with active geometry control by embedded piezoelectric actuators. Numerical modeling of mechanical deformation of a controlled helicopter blade was carried out using a coupled piezoelectric model and using a thermo-piezoelectric analogy. To verify the mathematical models, the results of a numerical study were compared with the results of laboratory tests of a structurally similar blade element made of composite materials with embedded piezoelectric actuators.
