Abstract
Abstract A mechanical assembly system for use in joining sections of towed arrays. Aypical section comprises an outer hose housing with aramid fiber strength members suitable for enclosing a line array of sensors and electronic equipment that are submerged in water and towed by a vessel. The hose is normally oil filled. The system includes an inner sleeve assembly, a cuff assembly, a bulkhead for forming an oil tight barrier and connecting electrical wiring, a positioning ring and a plurality of discs for spreading and terminating the aramid fiber strength members. In addition adhesives are used at various mechanical connections in the system.
