Demisable fuel supply system

A demisable fuel supply system (10) for a satellite includes a pressurized aluminum alloy tank (12) with an aluminum alloy propellant management device (20,22) therein. The propellant management device (PMD) can have any capillary action surface tension fluid transport features known in the art. Selected inner surfaces of the tank and the PMD are covered with a titanium based coating to guarantee propellant wettability and corrosion resistance of the fuel supply system.
