Design Blueprint: A Surface-Linked Hot-Gas Balloon Station for the Venus Deep Atmosphere: Buoyancy and Tether Sizing

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24199557): This study sizes a Surface-Linked Hot-Gas Balloon Station for the Venus Deep Atmosphere for operation in the Venus 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 float altitude of 12000.0 metres, ambient pressure at float altitude of 22.1 bar, ambient temperature at float altitude of 639.0 kelvin, net lift per cubic metre of 1.454 kilograms. 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 a civilian science and construction design intended for a robotically serviced surface station. The principal computed results are venus pressure bar of 92.0; venus temperature k of 735.0; venus density kg m3 of 65.0; venus gravity m s2 of 8.87. Further results include venus solar day h of 2808.0; venus night h of 1404.0; float altitude m of 12000.0; float pressure bar of 22.1. The design is a computed study for peaceful surface operations on Venus — power supply, thermal control, construction and resource handling for a surface station — and it has no targeting or weapon application. 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.
