The exhaust gases from the nozzle of a rocket motor usually contain significant proportions of unburned fuel. This fuel mixes turbulently with ambient air as the exhaust jet expands and may burn causing a substantial elevation of temperature in the exhaust plume. The secondary combustion is affected by factors such as velocity and altitude of the missile, motor thrust level, pressure, temperature at the nozzle exit plane. The addition of certain species such as HBR, K2SO4 etc. have been observed to inhibit the afterburning process. The inhibition of afterburning process is of great significance to the Air Force. However, the kinetic mechanism for the afterburning suppression is not understood. A research program has been initiated at the Rocket Propulsion Laboratory to investigate the afterburning suppression kinetics by Dr. Jay Eversole. The fundamental research objective will be to determine the chemical reaction mechanisms that are critical to this afterburning suppression phenomena. Keywords: Combustion inhibition. (kt)
