Abstract
An improved method for loading propellants into separate tanks on a reusable launch vehicle (RLV) uses three innovative methods. The liquid loading provides three liquid transfer methods, integrated and coordinated to provide less complicated loading and unloading operations, transfers, and cools and controls the liquids to provide a safe, cost effective solution to reusable vehicle tanking and de-tanking under commercial conditions. To insure the density of the propellant is maximized by cooling in a quick liquid loading environment, pre-cooling may be used.
