turbopump

A very long, detailed look at the A4/V2 rocket turbopump, the steam-turbine-driven twin propellant pump system. It covers the peroxide and permanganate catalysis that drives the turbine. This is part 1 of a series on V2 components.

Scott Manley explains the plumbing of rocket engines, including pressure-fed, gas generator, expander and staged combustion cycles. He shows why more complex designs exist and what they gain.
