Turbomachinery is the branch of engineering concerned with transforming mechanical energy between a rotor and a fluid or vice versa.  Higher altitude flights require larger fuel and oxidizer tanks which have thicker walls to account for high pressure fluids. LRI is using turbomachinery to deliver pressurized fuel and oxidizer to our engine to eliminate the mass cost of large tanks long terms. Our efforts are currently centered around the creation of a radial flow, centrifugal partial emission water pump, in which fluid entering rotates about a rotor multiple times before leaving through a radial outlet. A centrifugal pump allows for a higher pressure to be achieved while maintaining the desired flow velocity, which will enable us in the future to deliver high pressure fuel and oxidizer to our engine.
