How We Built and Tested 30bar ROCKET Propellant Tanks Using 304L Stainless Steel

Our rockets are 100% crowdfunded. Visit http://www.copsub.com/support-us to become one of our supporters!

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 video we pressure test our 3mm thick 304L stainless steel rocket propellant tanks for liquid oxygen (LOX) and ethanol to above their flight pressures to validate the tanks for flight as well as our automated TIG welding machine performance. In the process, we aim to deformation harden the 304L stainless steel to increase the volume of the tanks and their strength.
