Research of the technology of developing sensitive elements of rocket engine system pressure sensors

Abstract

A pressure sensor with a piezoelectric sensing element was developed for the information and measurement system of the technical condition of a rocket engine. The main technical characteristics of piezoelectric elements of laboratory specimens were obtained theoretically and experimentally. To analyze the microstructure of the piezoelectric element material, slices were made, and when analyzing photos of the cuts, it was found that the piezoelectric material has dense structure and the pores are small, evenly distributed over the volume. A laboratory model of technological equipment for plasma modification of charge based on lead and lead-free components was developed and tested.
