I am trying to calculate delta v of Starship - both as separate stages (Starship [SS], Super Heavy [SH]) and as a fully stacked rocket including 100t payload.
I know that I have to calculate 2 separate delta v values:
- for tha phase of flight when only SH fires and SS is a dead weight
- for when SS separates and fires its own engines
However I must be doing something wrong as I come up with very low total delta v for the full stack.
