Under this activity funded by the US Defense Advanced Research Projects Agency, Aerojet Rocketdyne successfully completed a series of 17 tests of liquid oxygen/kerosene, regeneratively cooled, liquid rocket thrust chamber assembly, demonstrating the performance, durability, and reusability of the design. These tests, the company said, explored a range of engine operating parameters, conditions, and run durations validating the design and applicability of the additive manufacturing, or 3-D printing, technology and its benefits.
