The payload section includes a shell, one or more penetrators disposed in the shell, and a charge for compromising the shell to deploy the one or more penetrators when the charge is initiated.
Claims10
A rocket-propelled grenade, comprising:
- a propulsion section comprising a booster propellant housing defining a nozzle and a groove;
- a payload section operably associated with the propulsion section and joined to the booster propellant housing, the payload section comprising:
- a shell;
- one or more penetrators disposed in the shell;
- and
- a charge for compromising the shell to deploy the one or more penetrators when the charge is initiated;
- a plurality of fins operably associated with the booster propellant housing;
- a plurality of biasing elements, corresponding to the plurality of fins, operably associated with the plurality of fins for biasing the plurality of fins to an unfolded configuration;
- and
- a spring ring disposed in the groove, such that the spring ring changes shape when the plurality of fins is deployed to lock the plurality of fins in a deployed configuration.
A rocket-propelled grenade, comprising:
- a propulsion section, comprising:
- a booster propellant housing;
- a casing joined to the booster propellant housing;
- a firing charge disposed at an aft end of the casing;
- a booster propellant disposed in the booster propellant housing;
- and
- a mechanical booster igniter operably associated with the booster propellant;
- a payload section operably associated with the propulsion section and joined to the booster propellant housing, the payload section comprising:
- a shell;
- one or more penetrators disposed in the shell;
- and
- a charge for compromising the shell to deploy the one or more penetrators when the charge is initiated;
- a plurality of fins, wherein the mechanical booster igniter comprises:
- an arming pin;
- a first spring-loaded locking pin engageable with the arming pin;
- a spring-loaded striker operably associated with the arming pin;
- a second spring-loaded locking pin operably associated with the spring-loaded striker and a fin of the plurality of fins;
- and
- a primer operably associated with the spring-loaded striker.
