Cryogenic-Insulated Habitat Thermal Control for Titan: Heat Leak, Heating Power and Airlock Loss Budget

This study sizes the Titan surface system named in its title for operation in the Titan surface environment, and reports the result as SIMULATED, NOT MEASURED. The design is developed from stated physical relations and a shared environmental basis, and every performance figure is computed by the deposited script rather than asserted. Among the computed results are envelope heat leak of 3960 watts, internal heat gain from occupants and equipment of 1,090 watts, net heating duty of 2870 watts. Mass and power budgets are assembled from components so that they can be audited, off-design behaviour and materials uncertainty are discussed openly, and the limits of the sizing are stated in full. The system is civilian life-support infrastructure: it keeps a staffed habitat warm and thermally stable on Titan's surface for the health and comfort of its occupants, and it has no application beyond that domestic function.
