Launcher Inc has scheduled the first full-scale test of its E-2 rocket engine for mid-2020 after securing a $1.5M award from the U.S. Air Force and taking delivery of the world's largest 3D printed combustion chamber. For more information see the IDTechEx report on 3D Printing Materials 2019-2029: Technology and Market Analysis.
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.
