Liquid rocket engine fuel injectors are critical to ensuring optimal combustion performance by controlling efficiency and stability. Interstellar Technologies has had great success utilizing the metal AM process to manufacture its injectors by drastically reducing the part count and simplifying the manufacturing process.
The challenge comes when focusing on performance improvement. Different AM platforms require different levels of post-processing machining to achieve the desired performance levels. In this case study, we explore Interstellar’s new Phoenix sub-scale fuel injector with real data from cold flow and hot fire testing.
