SpaceX Tests 3D Printed SuperDraco Thruster

When SpaceX’s Dragon orbital spacecraft takes its first crewed flights (possibly next year), it will be equipped with a new rocket engine that includes a 3D printed combustion chamber made of Inconel created by direct metal laser sintering (DMLS).

The SuperDraco engine will replace the original Draco engines, and serve as the vehicle’s launch emergency escape system. The company completed qualification testing of the engine earlier this year.

“Through 3D printing, robust and high-performing engine parts can be created at a fraction of the cost and time of traditional manufacturing methods,” says Elon Musk, chief designer and CEO at SpaceX. “SpaceX is pushing the boundaries of what additive manufacturing can do in the 21st century, ultimately making our vehicles more efficient, reliable and robust than ever before.”

The SuperDraco has roughly 200 times the power of its predecessor, and will provide attitude control for the Dragon capsule in orbit and during re-entry. It can also carry the capsule to safety during a launch accident. It can also help bring the Dragon capsule back to spaceport under its own power and provides precision landing capabilities. Each engine produces 16,000 lbs. of thrust, and can be restarted multiple times.

The Dragon will include eight SuperDracos built into its side walls that can produce up to 120,000 lbs. of total axial thrust.

Test firings of the engine were completed last month in Texas. The SuperDraco will undergo a pad abort test this year as part of NASA’s Commercial Crew Integrated Capabilities initiative.
