When replacing the metal combustion chambers of a low-thrust liquid rocket engine to combustion chambers made of carbon-ceramic composite material, a problem arises between the connection of metal and carbon-ceramic. To solve this problem, in this work presents the results of strength calculations of the connection of various materials in the form of a transition ring. Replacement of the material will avoid the effect of thermal coefficients of linear expansion on the operation of a low-trust liquid rocket engine to maintain the tightness of the joint node when exposed to operating temperatures.

Working Procedure

В статье рассмотрена задача определения резонансных характеристик камер сгорания жидкостного ракетного двигателя. Приведён и математически обоснован подход к созданию алгоритмов решения такой задачи с помощью анализа спектральной плотности мощности шумовых сигналов параметров рабочих процессов. Рассмотрены вычислительные эксперименты и продемонстрированы их результаты для модельного сигнала с единственной модой. In this article a task of determining of resonance characteristics for combustion chambers of a liquid rocket engine. The approach for development of algorithms to solve this task using analysis of power spectral density of noise signals of working procedure parameters is considered and mathematically justified. Computational experiments are considered and their results for a model signal with a single mode is demonstrated.
