The choice of the composition of the metal transition for the combustion chamber of low-thrust liquid thruster

Abstract

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.
