Abstract : An actuation system for a two-section encapsulating life raft system is provided which includes a manually releasable spring-based linkage assembly that normally serves to link a cable from the pressurized source for the encapsulating raft section and a cable for automatically actuating both the main raft section and the encapsulating section. Furthermore, by a simple manual operation, the linkage assembly undergoes rapid disassembly, and the cable for the pressurized source is disconnected from the actuating cable. A spring in the spring-biased assembly is compressed to store energy during connection of the assembly to the pressurized source cable, and the spring is retained in a compressed state as long as the linkage function is maintained. A manually removable retention pin is provided that normally retains the spring in the compressed state to retain the linkage function. However, when the retention pin is manually removed from the linkage retention position, the energy from the compressed spring is released, and the linkage assembly positively disassembles and disconnects the cable from the pressurized gas source from the linkage assembly. By breaking connection between the cable for the pressurized source and the linkage assembly, the cable for the pressurized source is disconnected from the actuation cable, thereby preventing the encapsulating raft section from being inflated.
