Robust, Automated, Stern Launch and Recovery System for USVs and Manned RHIB-Type Vessels

Physical Sciences Inc. (PSI) proposes to build upon prior work developing a unique patented in-stride stern launch/recovery system concept that utilizes a deployable, largely open, high wet-traction surface, powered"conveyor belt". It has built-in soft landing capability associated with transverse tension members or"V"shaped beams. It can operate through the water surface and if needed can be extended into the wake of the ship. The open belt design allows manned or unmanned, surface or subsurface, craft to drive onto the moving conveyor, be captured by the high-traction compliant surface, and then be transported up the sloping conveyor ramp system, out of the water and into the storage bay. The transverse members of the belt are designed to control the softness of the landing, and provide automatic centering. High wet traction surface material (demonstrated to hold up to 35 degrees) will be used for slowing the incoming vessel and transferring energy to the dissipating mode of the drive system. The system can accommodate launch and recovery of a variety of boats and vehicles.
