Robust Stern Launch and Recovery System for UUVs, USVs and Manned Underwater and RHID-Type Vessels [7285-021]

Conventional Launch and Recovery systems do not function automatically, at high ship speeds and in moderate sea states. The proposed system utilizes a unique concept of a deployable, largely open, flexible, “belt” conveyor ramp that can operate through and below the water surface in the wake of the ship with minimal drag. The open belt allows both manned and unmanned surface and subsurface craft to drive onto the moving conveyor with a soft landing and be transported up the sloping conveyor system out of the water and onto the cargo deck. The “belt” material and degree of tension utilized will affect the softness of the landing, provide automatic centering and the traction for hauling the vehicle from the water. No special adaptations should be required for the various vessel types being launched and recovered. The powered conveyor ramp slope control will allow partial lifting of the vehicle once it has landed on the moving surface, reducing the slope of the ramp. Projections from the vehicles, if any, will catch in the belt to provide more positive hauling forces. The hauling process can be readily reversed to launch vehicles within the size and weight capability of the system.
