Abstract
A geodesic, oblate spheroidally-shaped tank is disclosed containing a reversible diaphragm disposed within the tank. Liquid propellant is stored in the diaphragm housed within the tank, the propellant being expelled through an exit orifice of the tank by applying pressurant through an inlet orifice of the tank between the inner wall of the tank and the exterior wall of the diaphragm. The oblate spheroidal shape of the diaphragm/tank combination controls the collapse mode of the diaphragm for uniform expulsion of fluid contained therein.
