Cooling data were obtained for a transpiration-cooled afterburner having a porous combustion-chamber wail of brazed and rolled wire cloth for a range of exhaust-gas temperatures from 1200° to 3340° R, total flow ratio of cooling air to combustion gas of 0.025 to 0.106, and pressure altitudes of 15,000 to 45,000 feet. The data are successfully correlated over a range of Reynolds number from 75,000 to 1,500,000, based on the distance downstream of the leading edge of the porous wall.
