<p>A recovery apparatus for a training torpedo built to replicate an operational torpedo. The training torpedo is an elongated hollow housing substantially similar in shape to an operational torpedo. The nose portion is a shell (250) having a forward and aft portion, the forward portion being a cylindrical cavity (243) extending longitudinally into the shell. A cylindrically shaped piston (240) is adapted to be inserted into cylindrical cavity of the shell. The piston has a forward (241) and a rear portion (249), the forward portion being a pressure receiving surface. The piston is able to move forward and aft with respect to the shell. Attached to the piston is a retaining means (293, 296, 297). When a pressure is imposed upon the forward portion of the piston, the piston moves aft and the retaining means releases a plurality of weights (290). Located between the piston and the shell is a damping means (215). The damping means acts as a counter force to the pressure on the pressure receiving surface of the piston.</p> |
