FRANGIBLE ACTUATOR WITH REDUNDANT POWER SUPPLY

摘要

A device for restraining and then quickly releasing objects, comprising two half-spools (16, 18) that are held in place by a coil spring (28). The spring is attached at one end to one of the half-spools and at another end is held in place by a frangible wire (42), which is un turn connected to redundant power supplies (48, 52). Insulation is provided by coating a base portion (26) with aluminum oxide and attaching an insulator hub (34) to the end of the spring held by the frangible wire. Cut-outs (98, 102) within the coils are provided to maximize separation force.
