Abstract: 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.
Benefits: A robust yet simple launch and recovery system will be of great use for the deployment and retrieval of special forces craft in adverse sea states and at higher speeds than now possible, thus increasing safety and mission effectiveness. Additional users of this technology will include recovering research vessels and autonomous underwater vehicles, the offshore industry and salvage operators that have a need to safely deploy and recover surface craft in high sea states. The combination of a "soft landing" and use at moderate ship speeds, in principle to speeds greater than 20 knots, should make this relatively simple concept just what the Navy and marine industry currently need to safely launch and recover a diverse range of vehicles with minimal manning requirements.
