Abstract

Background. Object of research are modern methods of non-contact product diagnostics. The subject of research is a diagnostics of dynamic pressure gas flows near the peripheral ends of the bladed wheel of a turbomachine. The purpose of the work is the analysis of methods for diagnosing the parameters of turbomachines and the development of the design of a dynamic pressure sensor.
Materials and methods. The studies were carried out using the optical characteristics of fiber Bragg gratings.
Results. An analysis of non-contact diagnostic methods is carried out, the most relevant method based on the reflective properties of the optical fiber is identified. Proposed dynamic pressure sensor design.
Conclusions. Based on the analysis to diagnose the dynamic pressure gas streams in the area of the peripheral gap turbomachinery blade wheel sensor has been selected from fiber Bragg gratings. 

Key words

fiber, dynamic pressure, non-contact measurement methods, the fiber Bragg grating
