Exploratory development of a flexible pipe connection, similar to the currently used rubber insert sound isolation coupling, using fiber reinforced resin materials and elastomer is proposed. This effort will be directed towards the development of couplings for use in the controllable pitch propeller hydraulic piping and the prairie making piping on surface ships. The design of the coupling utilizes the knowledge obtained from the design of the couplings used on rubber insert sound isolation couplings, helicopter f elastomeric bearings, and laminated elastomeric joints used in drilling platform retention systems. Prior R&D on composite/ elastomeric bearings and composite rotor blades will be utilized in the composite design.
