Abstract
A squib assembly for a non-electric initiator of an anti-personnel obstacle breaching system includes a housing configured to connect to the igniter of a rocket motor of the anti-personnel obstacle breaching system, a slider assembly slidably contained within the housing and configured to connect to a shock tube of the non-electric initiator, and a pyrotechnic element disposed within the housing. Upon activation of the non-electric initiator, the squib assembly is configured to mechanically puncture a base of a initiator sleeve of the rocket motor and to thermally initiate ignition of the rocket motor.
Claims13
A squib assembly for a non-electric initiator of an anti-personnel obstacle breaching system, the squib assembly comprising:
- a housing configured to connect to an igniter of a rocket motor of the anti-personnel obstacle breaching system;
- a slider assembly slidably contained within the housing and configured to connect to a shock tube of the non-electric initiator;
- and
- a pyrotechnic element disposed within the housing;
- wherein, upon activation of the non-electric initiator, the slider assembly is configured to mechanically puncture a base of an initiator sleeve of the rocket motor, and the pyrotechnic element is configured to thermally initiate ignition of the rocket motor igniter;
- wherein the slider assembly comprises a tubular body defining a longitudinal passage therethrough;
- wherein the pyrotechnic element is disposed within the longitudinal passage;
- and
- wherein the slider assembly comprises a piercing end formed at one end of the tubular body, the piercing end being configured to mechanically puncture the base of the initiator sleeve of the rocket motor.
A non-electric initiator for an anti-personnel obstacle breaching system, the non-electric initiator comprising:
- a squib assembly configured to mechanically puncture a base of an initiator sleeve of a rocket motor of the anti-personnel obstacle breaching system and to thermally initiate ignition of the rocket motor;
- wherein the squib assembly comprises:
- a housing having a hollow interior;
- and
- a slider assembly at least partially disposed in the hollow interior of the housing and slidably moveable relative to the housing between a first position defined by a first stop and a second position defined by a second stop
- wherein the slider assembly comprises a tubular body defining a longitudinal passage therethrough;
- and
- wherein a pyrotechnic element is disposed within the longitudinal passage;
- and
- wherein the slider assembly comprises a piercing end formed at one end of the tubular body, the piercing end being configured to mechanically puncture the base of the initiator sleeve of the rocket motor.
A non-electric initiator for an anti-personnel obstacle breaching system, the non-electric initiator comprising:
- a squib assembly, the squib assembly comprising:
- a housing configured to connect to an igniter of a rocket motor of the anti-personnel obstacle breaching system;
- a slider assembly slidably contained within the housing, the slider assembly configured to connect to a shock tube of the non-electric initiator;
- and
- a pyrotechnic element disposed within the housing;
- wherein the slider assembly is configured to mechanically puncture a base of an initiator sleeve of the rocket motor, and the pyrotechnic element is configured to thermally initiate ignition of the rocket motor igniter upon activation of the non-electric initiator;
- wherein the slider assembly comprises a tubular body defining a longitudinal passage therethrough;
- wherein the pyrotechnic element is disposed within the longitudinal passage;
- and
- wherein the slider assembly comprises a piercing end formed at one end of the tubular body, the piercing end being configured to mechanically puncture the base of the initiator sleeve of the rocket motor.
