The Miniature Pressure Sensor for Monitoring and Diagnostics of Rocket-Space Engineering in Conditions of Mechanical and Thermal Effects

Abstract

The connected mathematical models of non-stationary thermal processes, of the thermoelastic strained-de­formed condition and strength of the miniature pressure sensor applied to monitoring and diagnostics of a con­dition of space-rocket engineering and functioning in conditions mechanical and thermal impacts are constructed. Are solved problems of calculation and the analysis of non-stationary temperature fields of the sensor and its thermoelastic is strained-deformed condition. Estimations of strength of the sensor are received at mechanical and thermal effects. The computer experiments verifying adequacy and functionability mathematical, algorith­mic and the software are conducted, quantitative estimations are received and recommendations on maintenance of effective functioning the miniature pressure sensor are developed. Keywords: miniature pressure sensor, temperature fields, strained-deformed condition, finite-element mathe­matical model, mechanical and thermal effects.
