Origami structure as an expulsion bladder for a rocket tank
Challenge: Supply of vapor-free cryogenic liquid propellant in a rocket tank
The key to propellant transfer in microgravity is the propellant management device (PMD), which ensures that vapor-free propellant is supplied from a source tank (e.g. a fuel depot) to a receiver tank or engine. Failure to do so for engines will result in combustion inefficiencies...
