Thermal Infrastructure Summary Report
Preliminary orbital compute thermal trade study
Model assumptions
Heat fraction: 98%
Emissivity: 0.9
Environmental derating: 70%
Sink temperature: 3 K
Radiator areal density: 8 kg/m²
Active overhead assumption: 5%
Passive overhead assumption: 0.2%
Active transport hardware: 35% of radiator mass
Passive transport hardware: 15% of radiator mass
Passive loop capacity: 5 kW
Interpretation
Under the selected assumptions, the distributed passive case reduces modeled thermal-system mass by 390 kg (18.8%) and thermal overhead by 4.8 kW relative to the centralized active baseline. These values are first-order trade-study outputs and are highly sensitive to radiator temperature, emissivity, environmental loading, areal density, and architecture assumptions.
