🚀 Multistage Rocket Lab: Equal-Ratio Stage Split, Payload Fraction and Gravity-Loss Ascent

Design a generic multistage rocket and fly it: choose total delta-v, the split between stages, the structure fraction, propellants and number of stages, then watch the Tsiolkovsky mass design and a simulated gravity-turn ascent to orbit. Shows why one stage is not enough, where the optimal split lies, and how gravity, drag, pressure and steering losses eat the ideal delta-v. Blender-modelled rocket and launch pad.
