Science and Technology Applications, LLC's (STA) vision for a versatile space propulsion system is a highly throttleable, high performance, and cost effective Liquid Oxygen/Hydrogen engine utilizing innovative design and manufacturing processes to simultaneously meet NASA's Space Exploration requirements. To that end, an innovative injector element concept is proposed consisting of axial flow coaxial injectors with pintle center post. This element concept is expected to provide deep throttle capability while maintaining performance over the entire range. Cold flow tests will be performed to characterize mixing and atomization distribution.
