Abstract

The paper considers design of the liquid-propellant rocket engine combustion chamber. Artificial roughness application area in the chamber shells is shown, and the existing methods to obtain artificial roughness in the rocket propulsion engineering are analyzed. The paper presents advantages and disadvantages of the existing technologies used in mechanical engineering for surface treatment of products being a part of the liquid-propellant rocket engine combustion chamber. Promising methods for obtaining artificial roughness on the rocket engine parts surfaces are demonstrated. Progressive means of technological equipment are considered to obtain artificial roughness by the mechanical machining on the surfaces of those parts that ensure integrity of the surface layer of the critical structural elements in the liquid-propellant rocket engines. The results obtained make it possible to significantly expand the production technological capabilities, as well as to seriously improve technical characteristics of the special equipment products in the aerospace and space industries.
