Abstract
A rollonet designed to provide positive displacement of liquid rocket prolants for missle 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.degree. away from the tank wall in a progressive manner.
