FIG. 7 shows an air cannon system loaded with a launch canister containing a prop-fouler. A pressure vessel (28) contains an inlet including a poppet valve (100) that, upon command, can be selectively placed in either a one-way flow position to permit charging of the pressure vessel or otherwise opened to trigger rapid discharge through pressure equalization with the ambient environment. The air cannon may include multiple splayed barrels or a single barrel (158). A launch canister (202), realized in the form of a tube, has a driving plate (350) that closes an end of the launch tube. The driving plate is the first point loaded into the barrel. Within the launch canister (202) a first portion of a floating prop-fouling line is stored. The prop-fouling line, such as made from Dyneema®, has at its ends two drogues that, upon entry into the water, fill with water to produce drag resistance to movement of the prop-fouling line. To avoid undue stress on canopy panels of each drogue and to avoid twisting of shroud lines (312) to the canopy, a rotating shackle (310a, 310b) acts as a coupling point between the shroud lines (312) and the prop-fouling line. Only one drogue (306), its associated coupling and a selected length prop-fouling line are loaded into the launch canister, with the other drogue and its rotating shackle (310b) loaded into a cradle (166). Upon firing, gas expansion causes the rapid acceleration and ejection of the launch tube (202) and generally straight line deployment of the prop-fouling line (302).

Expanded structures are formed by cutting a series of concentric rings or sections from a single block or sheet of solid material. The "rings" need not be circular, but may be any regular or irregular geometric or other shape as desired, so long as they are substantially concentric with one another. The cuts are made so that they angle outwardly from the upper to the lower surface of the block or sheet, and pass completely through the sheet or block. This provides a series of concentric sections, with each section having a lower, outer periphery which is at least slightly larger than the upper, inner periphery of the next larger adjacent section. This allows each section to be stacked atop a larger adjacent section, with the lower outer edge surface of each smaller section resting upon the upper inner edge surface of the larger section immediately therebelow. Alternatively, the tapered outer and inner walls or faces of adjacent sections may be wedged together, with an adjacent inner section protruding somewhat from the plane of its adjacent outer section. Such structures may be formed in virtually any practicable size, from utility sheds including door and window openings formed therein, to smaller household containers, works of art, etc. as desired. The structures may be made permanent by coating with a suitable material (e.g., glass fiber and resin, etc.) if so desired. Different colors of materials may also be assembled together, to produce structures having alternating bands of colors therein.
