Abstract
A pyrotechnically powered actuator having a bellows that provides a force and stroke upon initiation is disclosed. The actuator includes a housing body with a first end and a second end. The bellows is coupled to the first end of the housing body. A cover is coupled to the second end of the housing body. An initiator is located within the housing body and includes a pyrotechnic material and a bridge element. The housing body, the bellows, and the cover define a hermetically sealed chamber. The bellows is compact, lightweight, and can withstand internal and external pressure at least as high as 3,000 psi. An exemplary embodiment includes a housing body that provides a compartment for adding supplemental pyrotechnic material. Further exemplary embodiments of the actuator include a chip initiator that requires less than 1 amp to function in less than 10 milliseconds.
