Spacecraft and mission design for the SP-100 flight experiment

“…Thermal radiation from arcjet thrusters also can be severe, since up to 10% of the engine input power can be radiated away by the nozzle alone. 33 ' 34 Heat shields will be required to reduce radiative heating of the upstream spacecraft components.…”

“…The baseline values come from performance test results discussed earlier, 33 ' 34 whereas the advanced arcjet values are projected based on theory and the previously mentioned test results. The orbital analysis was not trajectory optimized to achieve the maximum inclination possible when throttling the arcjet engines.…”
