A Buoyant Lake Submersible for Titan: Displacement, Propulsion and Endurance Energy 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 displaced mass at full immersion of 540.0 kilograms, reserve buoyancy of 20 kilograms, hull gauge pressure at design depth of 152.1 kilopascals. 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 submersible is a civilian science vehicle for surveying lake depth, chemistry and bed morphology; it carries cameras, sonar and water samplers only, and has no application beyond peaceful exploration of the lakes.
