【 摘 要 】

The authors developed a numerical 3D model of a piezoelectroluminescent fiber-optic sensor for diagnosing a volumetric stress-strain state in a helicopter blade with controlled geometry. The authors of the article have performed a numerical calculation of non-uniform coupled electro-elastic fields in the elements of a sensor fragment embedded in a fiberglass sheathing of the main helicopter propeller. The calculation was carried out taking into account the action of the control voltage on the sensor electrodes. The numerical values of the informative and control coefficients of the sensor necessary for diagnosing the components of the strain tensors at the macro and micro levels of the textile composite are calculated.
