Sound reducing systems for use with projectile launchers
A cassette for deploying one or more entangling projectiles includes a pair of sockets, each socket being in fluid communication with a pressure source. An entangling projectile includes a pair of anchors connected by a tether, each of the pair of anchors being positionable within one of the sockets and the tether being carried by the cassette. Each socket carries a slidable piston positionable in a respective socket between an entangling projectile and the pressure source such that each slidable piston is propelled along a respective socket in response to a pressure wave generated by the pressure source to thereby expel the anchor from the socket. Each of a pair of retaining clips is engageable with an anchor and with a socket to aid in retaining the respective anchor in the respective socket prior to generation of the pressure wave.
1. A cassette for deploying one or more entangling projectiles, the cassette comprising:
a pair of sockets, each socket being in fluid communication with a pressure source;
an entangling projectile including a pair of anchors connected by a tether, each of the pair of anchors being positionable within one of the sockets and the tether being carried by the cassette;
each socket carrying a slidable piston positionable in a respective socket between an entangling projectile and the pressure source such that each slidable piston is propelled along a respective socket in response to a pressure wave generated by the pressure source to thereby expel the anchor from the socket; and
a piston stop positioned at an end of each socket, each piston stop preventing a respective piston from exiting a respective socket, the piston stops each including a lip extending radially inwardly into an end of each respective socket, each lip extending only partially about a circumference of each respective socket, so as to define a tether notch opening therein.
2. The cassette of claim 1 , wherein each anchor includes an anchor orientation protrusion alignable with a respective tether notch opening in a respective lip while a respective anchor is installed in a respective socket.
3. The cassette of claim 1 , wherein each piston includes a first, relatively rigid component coupled to a second, relatively pliable component, the pliable component having an outer diameter greater than an inner diameter of the socket, engagement between the outer diameter of the pliable component and the inner diameter of a respective socket partially retarding movement of a respective piston within a respective socket.
4. The cassette of claim 1 , further comprising a pair of retaining clips, each engageable with an anchor and with a socket to aid in retaining the respective anchor in the respective socket prior to generation of the pressure wave.
5. The cassette of claim 4 , wherein each socket includes a piston stop positioned at an end of the socket, the piston stops preventing a respective piston from exiting a respective socket, and wherein each retaining clip includes at least one arm that engages a respective piston stop.
6. The cassette of claim 4 , wherein each retaining clip is formed from a sacrificial material.
7. The cassette of claim 6 , wherein each the retaining clip is formed from plastic.
8. A cassette for deploying one or more entangling projectiles, the cassette comprising:
a pair of sockets, each socket being in fluid communication with a pressure source;
an entangling projectile including a pair of anchors connected by a tether, each of the pair of anchors being positionable within one of the sockets and the tether being carried by the cassette;
each socket carrying a slidable piston positionable in a respective socket between an entangling projectile and the pressure source such that each slidable piston is propelled along a respective socket in response to a pressure wave generated by the pressure source to thereby expel the anchor from the socket; and
a pair of retaining clips, each engageable with an anchor and with a socket to aid in retaining the respective anchor in the respective socket prior to generation of the pressure wave;
each socket including a piston stop positioned at an end of the socket, each piston stop preventing a respective piston from exiting a respective socket, and wherein each retaining clip includes at least one arm that engages a respective piston stop.
9. The cassette of claim 8 , wherein each retaining clip includes a pair of arms that each slidably engage one of a pair of sloped pockets formed in a respective anchor.
10. The cassette of claim 8 , wherein each retaining clip is formed from a sacrificial material.
11. The cassette of claim 10 , wherein each retaining clip is formed from plastic.
12. The cassette of claim 8 , wherein each piston stop includes a lip extending radially inwardly into an end of a respective socket.
13. The cassette of claim 12 , wherein each lip extends only partially about a circumference of a respective socket, so as to define a tether notch opening therein.
14. The cassette of claim 13 , wherein each anchor includes an anchor orientation protrusion alignable with a respective tether notch opening in a respective lip while a respective anchor is installed in a respective socket.
15. The cassette of claim 14 , wherein each anchor orientation protrusion engages the tether when a respective anchor is installed in a respective socket.
16. The cassette of claim 8 , wherein each piston includes a first, relatively rigid component coupled to a second, relatively pliable component, one of the pliable component or the rigid component having an outer diameter greater than an inner diameter of a respective socket, engagement between the outer diameter of the anchor and the inner diameter of the socket partially retarding movement of a respective piston within a respective socket.
