In this video we talk about our rocket fuel injector soldering for the Spica rocket BPM100 ethanol/LOX engine. These coaxial swirl injectors will first be tested on a smaller BPM5 engine to validate their optimal design. And we also go through our nearly-finished 304L stainless steel propellant tank bulkheads, among other developments.

Copenhagen Suborbitals is the world's only crewed, crowdfunded space program. In the future, a volunteer astronaut will fly to space on our home-built rocket. We do this on our spare time, all the donations go to paying our workshop rent and buying materials. We are forever thankful to each of our supporters!
