Vliv čistoty kapaliny při testování opotřebení titanových ventilů

Abstract

The growing ambitions of the aerospace industry require the continuous development and innovation of components subject to extreme stress. The implementation of innovated segments into the system is preceded by a series of tests, which verify the concept in terms of functionality, reliability, efficiency and safety in operational and crisis conditions. As part of the optimization of the fuel system of the Vega E carrier rocket, the concept of the fuel valve of the correction engine, which is intended for stabilization and orientation of the rocket in space, was modified. Subsequently, it was necessary to adequately verify the optimized design by a series of tests that simulated operational and crisis conditions. The presented diploma thesis deals with one of the tests, namely the effect of the purity of the fluid on the wear of the titanium valve, which is part of the fuel system of the correction engine. The aim of the diploma thesis is not only a comprehensive design of test methodology, implementation and subsequent evaluation of the tested valve during the test of the effect of fluid purity on wear, but also the determination of the relevant test methodology of similar components.
