3D printed by AMCM (An EOS Group Company) in Copper Alloy on AMCM’s M4K machine, it is the world’s largest liquid rocket engine combustion chamber 3D printed in a single part. The combustion chamber is 34in (86cm) tall with an exit nozzle diameter of 16in (41cm).
The combustion chamber and injector are critical parts of Launcher’s E-2 engine, the highest performance engine for small satellite launch vehicles, currently in development. The first full-scale test fire is scheduled for Q2 2020.
Launcher has already achieved its target combustion performance of 98%+ C using sub-scale versions of the E-2 engine 3D printed with the same machine and materials.
Launcher was recently awarded $1.5M at the U.S. Air Force Space Pitch Day to accelerate the Launcher E-2 development and testing program.
