Rocket armament with ignition prevention and motor separation features
The patent US12018913B2 describes a rocket-based armament designed for launch from a tubular launcher, featuring a combination of innovative components aimed at enhancing safety and operational efficiency. The armament includes an effective payload, a rocket motor connected to the payload for propulsion, and a pyrotechnic assembly that ejects the rocket motor and payload from the launcher while igniting the motor. A key feature is the gas dispersion assembly, which prevents the ignition of the rocket motor when the armament is not encased in the launcher, even if the pyrotechnic assembly is activated. This assembly consists of a dispersing openings array and a bushing member that acts as a piston, ensuring that gas produced during the pyrotechnic actuation does not ignite the rocket motor.
Additionally, the patent outlines a cutting and separation assembly that operates under gas pressure from the rocket motor. This assembly includes a cutting piston that moves linearly to sever the connection between the rocket motor and the effective payload, aided by a spring mechanism. Once the connection is cut, the assembly facilitates the thrust of the rocket motor, allowing it to separate from the payload during flight. The armament is specified as a 40 mm device, suitable for launch from grenade launchers or single-use disposable canisters, thereby broadening its application in military and defense scenarios.
