Actuators for gun-fired projectiles and mortars

摘要

A method for providing actuation thrust to a projectile. The method including: providing two or more individual actuators movably disposed in a stack housing, each of the two or more individual actuators being separated by a separation layer; accelerating exhaust from the two or more individual actuators with an accelerating nozzle having at least a convergent section terminating at a throat; and maintaining a constant volume in the accelerating nozzle after actuation of each of the two or more individual actuators.

主权项

1. An actuator stack comprising:
a stack housing; two or more individual actuators movably disposed in the stack housing; a separation layer formed between adjacent individual actuators; an accelerating nozzle having at least a convergent section terminating at a throat; and a biasing member for moving one of the two or more individual actuators towards the accelerating nozzle after another of the two or more individual actuators has been burned, wherein at least one of the two or more individual actuators comprises; a detonation charge; a primer for igniting the detonation charge; and detonation wiring for powering the primer.
