Variables

Detailed Description

Propellant tank capacity helpers for flight simulation.

Max loadable propellant mass is resolved from config — not a hardcoded fill fraction.
Priority:
  1. design_requirements.{lox,fuel}_tank_capacity_kg (explicit mass cap)
  2. tank_volume_m3 × density × fill_factor
  3. π r² h × density × fill_factor

Fill factor comes from design_requirements.propellant_tank_fill_factor (default 0.90).

Return (max_mass_kg, volume_m3, fill_factor, used_explicit_capacity).

If design_requirements.{branch}_tank_capacity_kg is set, that mass is used directly
(fill_factor still reported for diagnostics).
