Why rocket engine valves are difficult. Specifically the liquid oxygen ones.

Our rockets are 100% crowdfunded. Visit http://www.copsub.com/support-us to become one of our supporters! Compliment us by wearing our apparel: https://www.zazzle.com/store/copsub Book a visit to our rocket factory in Copenhagen: https://www.airbnb.com/copsub In today’s video, we will talk about the culprit of so many hard starts, failed starts, off-nominal mixture ratios, as well as rocket and spacecraft delays universally - propellant valves. And we will try to answer whether our home-built liquid oxygen valve prototype for our upcoming 100kN ethalox rocket engine can actually do its job under all the cryogenic pressure. 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!
