Kratos designs, builds, and tests space and derivative technologies, including liquid rocket engine turbopumps, turbo-generators, boost pumps, electric pumps, oil-less turbochargers, as well as coatings and additive technologies. We have extensive experience with liquid hydrogen, methane, oxygen, RP-1 & RP-2, as well as hypergolic and super critical CO2 systems. Kratos’ capabilities range from hydraulic turbines, to extreme pressure and temperature gas turbines. We develop electrically driven pumps with submerged cryogenic motors, such as an in-line liquid hydrogen boost pump, designed to be submerged in the liquid hydrogen tank and deliver sub-cooled hydrogen to the main engine. The power density and resultant pressures in these products is what sets them apart.
All analysis is conducted in-house using well-calibrated codes. We can model every aspect of the turbopump, including: pump and turbine flow path, rotordynamics, bearings (rolling element and hydrostatic), thrust balance and secondary flows, structural and heat transfer, steady state and transient modeling, as well as mechanical design and product definition. From prototypes to production units, Kratos is capable of manufacturing all turbopump components, including assembly, instrumentation, and support testing.
