ABSTRACT:
A process of making and filling an envelope shaped as a ring airfoil for use as a projectile. The envelope is formed of resilient material into a tubular shape with an outer wall portion and an inner wall portion located along the tubular extent thereof with a foldable portion therebetween. The walls are relatively moved to form a payload cavity by moving the inner wall to nest within the outer wall by folding at the foldable portion with the ends contiguous. The foldable portion forms the leading edge of the airfoil. The trailing edge is formed by joining the contiguous ends. Payload filling and final sealing steps complete the airfoil projectile shape.
