Fiber-Optic Measurement Technology and the Phase-Chronometric Method for Controlling and Monitoring the Technical Condition of Aircraft Structures

The assurance of safe aircraft operation is considered in terms of the fatigue life of its structure. The article demonstrates the relevance of developing and implementing diagnostic systems to monitor the structural condition of complex technical objects on the example of a helicopter. The authors present an original approach to developing and implementing complex systems for diagnostics and monitoring the condition of complex technical objects. This novel approach combines a fiber-optic measurement technology and a phase-chronometric method. The application of monitoring and diagnostic systems is shown to ensure a transition to an operational technical condition. The proposed approach facilitates an increase in maintenance intervals and a reduction in the excess safety margins of structures, leading to more reliable aircraft performance.
