Turbopump Testing and Diagnostics
, 2018 Liquid-propelled rocket engines are the current state-of-the-art in the space propulsion industry. Turbopumps are used to deliver the necessary engine conditions to ensure the large chamber pressurization that liquid-propelled systems require. As there is no record of any full-scale development of a rocket turbopump in academia, Purdue University and ...
