摘要： Some embodiments pertain to a tool that includes a first arm and a second arm that is rotatably connected to the first arm. The first arm includes an opening and the second arm includes a projection that engages threads on a fastener which is installed within the opening in the first arm. During operation of the tool, a fastener is inserted into the opening in the first arm. Pressure is applied to bring the first and second arms together such that the projection engages the threads of the fastener and then deforms the threads. The first arm may include a plurality of threaded openings such that each opening is adapted to receive a different diameter fastener. In addition, the second arm may include a plurality of projections such that each projection is a different size and is aligned relative to one of the openings in the first arm.

摘要： A multi-pulse propulsion system (10) includes at least one pulse chamber (20) containing at least one propellant (22) for igniting during at least one pulse of the multi-pulse propulsion system, at least one additional pulse chamber (24) containing at least one additional propellant (26) for igniting during at least one additional pulse of the multi-pulse propulsion system, and at least one passive fuzing system (34) configured to initiate the at least one additional pulse. The at least one passive fuzing system includes a sensor (36) and an igniter (38). The sensor is configured to sense an environmental condition and/or a ballistic condition. The igniter is configured to provide a stimulus that causes ignition of the at least one additional propellant in response to the sensor sensing that the environmental condition and/or the ballistic condition has reached or exceeded one or more threshold values.
