ANALYSIS, FEASIBILITY, AND WALL-TEMPERATURE DISTRIBUTION OF A RADIATION- COOLED NUCLEAR-ROCKET NOZZLE

Technical Report ·
OSTI ID:4804708
;
An analysis was made to determine the feasibility of operating radiation- cooled rocket nozzles with hydrogen as the propellant. Wall-temperature distributions and heat fluxes along the nozzle were calculated and presented over a range of chamber pressure and wall emissivity. Development of radiation-cooled nozzles may prove to be difficult because of high nozzle wall-temperature levels, but it appears to be desirable because of the potential performance gains in terms of specific impulse associated with these nozzles over regeneratively cooled nozzles and the anticipated difficulty of regenerative cooling at high chamber pressures.
