Hydra serves as a test stand and feed system; it's structure is rated to secure an engine with a maximum of 1000 lbf and provides a remotely operated pressure regulated feed system for liquid rocket engines. It was designed with several key aspects in mind: portability, modification, versatility, and safety. Hydra is a critical milestone for LPL’s future capabilities and will be used as a platform to test and modify future engine and feed system ideas.
Hydra is a workhorse for liquid rocket engine research and development and allows LPL's members to learn about the operations, electronics, control, high pressure systems, sensors, safety, valves and a host of other feed system topics affecting liquid rocket engines
