Abstract: Cooling data from this experimental afterburner are successfully correlated over a range of Reynolds number based on the distance downstream of the leading edge of the porous wall. Calculations based on the correlation indicate that the combustion-chamber cooling-air requirements for an exhaust-gas temperature of 3700° R are only 16 percent of the air required for conventional forced-convection cooling. The cooling-air requirements were nearly independent of flight condition, but close control of cooling-air pressure is required at high flight speeds.
