Abstract:

An attempt is made to present a unified review and evaluation of the current status concerning the emission of optical radiation from rocket exhaust plumes. This topic has been under intensive investigation for various applications since the 1940s and of recent date centered upon the base heating problem. Thus this subject is of serious concern to the engine as well as the vehicle designer. The emission characteristics of rocket exhaust plumes are strongly dependent upon the aerothermochemistry of the plume. The latter, of course, is related to rocket engine parameters and the specific propellant system employed. Conditions created within the exhaust are different for liquid and solid propellants. Notably, the copious amount of large particles in the efflux of metal based solid propellant motors alter the fluid mechanics and radiative transfer of their exhaust plumes and therefore must be taken into account.
