Abstract

Within the frame of a broader activity towards research into the application of methane in cryogenic liquid rocket engines, the efficiency of film cooling was studied in a LOX/CH4-fired subscale size model combustor. Aiming at booster as well as upper stage applications, the combustion pressure levels were varied between 4 MPa and 7 MPa. The effectiveness of the ambient temperature film was determined in axial and circumferential directions measuring temperatures in the copper liner. The experiments revealed remarkable circumferential differences of the film efficiency which remain existent far downstream and which are more pronounced at higher pressures.
