Measurement of deformation of aircraft structures made of composite materials with fiber-optic sensors

The paper considers the relevance of the problem of measuring the deformation of aircraft structures in connection with the increasing volume of use of materials similar to an increasing number of parts and structures of aircraft and helicopters, as well as unmanned aerial vehicles. The necessity of monitoring the state of materials and structures in real time with the analysis of the current state and operating modes of aircraft, supplementing the pilot assistance system is shown. An overview of fiber-optic sensors and measurement technologies used in various types is presented, as promising for use in diagnostic systems, with the possibility of embedding into the structure of composite materials. A method is proposed for choosing the type of fiber-optic sensors for monitoring various parts of aircraft, depending on the characteristics.
