NOT KNOWN FACTS ABOUT APOLLO 3.5 BLUE PLUS PROCESSOR

The S-IVB also continued to thrust at a lower stage by venting gaseous hydrogen, to maintain propellants settled of their tanks and forestall gaseous cavities from forming in propellant feed lines. This venting also taken care of Risk-free pressures as liquid hydrogen boiled off from the gas tank. This venting thrust quickly exceeded aerodynamic dr
