Presented is a summary of the analytical and experimental effort to investigate and develop a film protected, convectively cooled nozzle for advanced solid rocket applications. The work performed included thermochemical analyses of the reactions encountered in the boundary layer between the injectant, the free stream, and the nozzle wall heat transfer analyses on alumina particle radiation and convection heat transfer to the nozzle wall fluid mechanics analysis of injection into a turbulent boundary layer with accelerating flow cold flow laboratory experiments on injection into a turbulent boundary layer through discrete holes and rocket motor tests of the cooling concept on a solid propellant simulator.
