The article formulates a mathematical model for calculating the stress-strain state (SSS) of a model helicopter blade equipped with piezo actuators. In determining the twist angle of the model blade, the principle of thermo-piezoelectric analogy was used, which allowed moving from the related boundary problem of electro elasticity to the boundary problem of thermo elasticity. A comparison was made of the deformation fields for model blades with various arrangement of piezo actuators and different materials of the spar. We analyzed the convergence of the finite element model of the blade. The limiting twist angles of the model blade were determined in the range of the control voltages operating values applied to the piezo actuators. Recommendations for the placement of piezo actuators on a model helicopter blade were formulated.
