FIG. F-13. (a) Flexichoc. (1) Two plates are separated by compressed air until they lock into position; (2) the air between them is pumped out; (3) on signal the plates are unlocked and water pressure forces them together; the inrush of water into the consequent empty space creates a shock wave in the water. (b) Flexotir; small charges (about 2 ounces) are propelled through a rubber hose by water under pressure into a steel cage, where they are detonated; holes in the cage allow water repelled by the explosion to flow out and in, dissipating the energy.
