Voidbreaker Design Baseline — Verified Parameters
Purpose This document records the verified design parameters for the Voidbreaker, derived from the rocket equation and basic geometry. All figures are internally consistent. Where estimates are used (exhaust velocity, VoidForge mass), the assumptions are stated explicitly. This document exists to provide a stable numerical reference — other documents in the corpus should not contradict these figures without updating them here first. Assumptions Parameter Value Basis Cruise speed 0.02c = 6,000 km/s Mission requirement Exhaust velocity (ve) 0.03c = 9,000 km/s Fusion drive (D-T or D-He3, near-term feasible) VoidForge active mass ~175t Midpoint of estimated 150–200t range Hull + tank structure ~300t Working estimate Dry mass (post-decel) ~475t VoidForge + hull These figures are working estimates, not engineering results. The exhaust velocity assumption is the most consequential: a lower ve increases propellant requirement; a higher ve reduces it. At ve = 0.03c the mass ratios are consistent with the propellant figures below. ...
