A summary is given of research and development progress on the study, design, and testing of an experimental liquid hydrogen pump for flight vehicle systems. Program aims are 1 materials selection, 2 mechanical design and manufacture of a piston-type pump, 3 testing of pump performance throughout the quality range of 0 to 100 at a pump inlet pressure of 3 atmospheres absolute, 4 delivering a variable mass flow from 2 to 12 1bhr at a discharge pressure of 1200 psia throughout the entire inlet quality range, and 5 testing toward an objective of 300 hours of operation on one piston and cylinder.
