Back-To-Back, Counterrotating Turbopumps
Abstract
Pair of counterrotating turbopumps mounted back to back in novel one-piece volute housing. Serves as spool piece into which pumps inserted, one from each end. Includes turbine inlet and outlet volutes. Enables easy replacement of each pump/turbine assembly. Designed to provide fuel and oxidizer to rocket engine at high pressures; modified versions useful in providing other two-fluid high-pressure flows or redundant high-pressure flow of single fluid.
