Abstract : The patent relates to a rollonet designed to provide positive displacement of liquid rocket propellants for missile tankage, comprising an inner and outer diaphragm each in the form of a continuous cylinder with a piston head therebetween. Gas pressure acting on the piston head imparts an axial thrust on the prerolled portions of the inner and outer cylinders, causing them to roll through 180 degrees away from the tank wall in a progressive manner.
