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 in our spare time, all the donations go to paying our workshop rent and buying materials. We are forever thankful to each of our supporters!
In this episode, we take a look at our coaxial swirl injector technology that we recently tested on our BPM-5 rocket engine and compared its performance to our old showerhead injector design. We had four brass rocket fuel injectors and one 3D metal-printed stainless steel injector on our rocket engine test stand. Here is a quick look at the combustion instability we saw while making mach, or shock diamonds this Easter.
