SpaceX Completes Qualification Testing of SuperDraco Thruster.

Thruster to Power Revolutionary Launch Escape System on Dragon Spacecraft.

Space Exploration Technologies Corp. (SpaceX) announced today that it has completed qualification testing for the SuperDraco thruster, an engine that will power the Dragon spacecraft’s launch escape system and enable the vehicle to land propulsively on Earth or another planet with pinpoint accuracy.

The qualification testing program took place over the last month at SpaceX’s Rocket Development Facility in McGregor, Texas. The program included testing across a variety of conditions including multiple starts, extended firing durations and extreme off-nominal propellant flow and temperatures.

The SuperDraco is an advanced version of the Draco engines currently used by SpaceX’s Dragon spacecraft to maneuver in orbit and during re-entry. SuperDracos will be used on the crew version of the Dragon spacecraft as part of the vehicle’s launch escape system; they will also enable propulsive landing on land.  Each SuperDraco produces 16,000 pounds of thrust and can be restarted multiple times if necessary.  In addition, the engines have the ability to deep throttle, providing astronauts with precise control and enormous power.

The SuperDraco engine chamber is manufactured using state-of-the-art direct metal laser sintering (DMLS), otherwise known as 3D printing.  The chamber is regeneratively cooled and printed in Inconel, a high-performance superalloy that offers both high strength and toughness for increased reliability.

“Through 3D printing, robust and high-performing engine parts can be created at a fraction of the cost and time of traditional manufacturing methods,” said Elon Musk, Chief Designer and CEO.  “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.”

Unlike previous launch escape systems that were jettisoned after the first few minutes of launch, SpaceX’s launch system is integrated into the Dragon spacecraft.  Eight SuperDraco engines built into the side walls of the Dragon spacecraft will produce up to 120,000 pounds of axial thrust to carry astronauts to safety should an emergency occur during launch. 

As a result, Dragon will be able to provide astronauts with the unprecedented ability to escape from danger at any point during the ascent trajectory, not just in the first few minutes.  In addition, the eight SuperDracos provide redundancy, so that even if one engine fails an escape can still be carried out successfully.

The first flight demonstration of the SuperDraco will be part of the upcoming pad abort test under NASA’s Commercial Crew Integrated Capabilities (CCiCap) initiative. The pad abort will be the first test of SpaceX’s new launch escape system and is currently expected to take place later this year.
