The fluid’s cryogenic temperatures and high combustion rate posed technical problems, but its low weight and high energy were unrivaled. Lewis researchers began studying high-energy propellants in the mid-1940s and by the early 1950s were concentrating on liquid hydrogen. The Lewis Flight Propulsion Laboratory built the Propulsion Systems Laboratory (PSL) and upgraded the Altitude Wind Tunnel (AWT) to test these new, more powerful engines. Hydrogen-fueled 304 Suntan engine Not having any prior experience with liquid hydrogen, a super-cold substance that boils at minus 423 degrees Fahrenheit, there was much for Pratt & Whitney engineers to learn. The RL10 was the first liquid hydrogen rocket engine to be built in the United States, with development of the engine by Marshall Space Flight Center and Pratt & Whitney beginning in the 1950s.
