Research into thermal efficiency of film cooling along combustion chamber wall of low-thrust rocket engine

The paper focuses on experimental study of the film cooling efficiency in combustion chambers of liquid propellant low-thrust engines. A completeness rate of the research into different parameters affecting the thermal efficiency of film cooling is analyzed. The thermal efficiency proves to be mostly influenced by such factors as a coolant mass flow-rate, a coolant feed slot design, and flow parameters of both the main flow and a cooling component. Combustion chamber pressure produces slight effect on the film cooling thermal efficiency. Guidelines for film cooling in low-thrust rocket engines are presented. The authors use the results of both Russian and foreign studies, which are publicly available.
