Design Blueprint: A Lake-Current Turbine for Electrical Power from Moving Liquid Methane on Titan

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24202939): 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 electrical power output of 54.1 watts, kinetic power available in the current of 198.8 watts, rotor speed of 9.55 revolutions per minute. 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 turbine is a civilian power system for a lake-shore science station; it carries no payload other than its generator and has no application beyond supplying electricity to instruments and habitat plant. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json. The design is a civilian science, mobility and power system for Titan surface operations and has no targeting or weapon application.
