Description

MDG proposes to develop an expandable/collapsible, remotely operated, Modular Unmanned Vehicle Recovery System (MUVRs) that combines inflatable elements with a rigid collapsible frame incorporated with commercial off the shelf (COTS) Remotely Operated Thrusters (ROTs). The self-powered, remotely controlled MURVs allows the recovery of an unpowered (Dead Fish in the Water) UxV and enables a single operator, from on-board any host platform, to maneuver the MUVR and perform launch and recovery of the UxV without the need for manned support in the water significantly reducing risk. The MURVs performs as protective carrier for the UxV, further reducing risk of damage to any fragile sensors or arrays during launch and recovery operations. MDG will design the MUVR system using a combination of drop-stitch inflatable panels, a modular aluminum cradle, remotely operated thrusters with teleoperation system, a winch, a tether and an air inflation/deflation system.  Combining drop-stitch inflatable textiles technology with rigid structural members, creates a HIRS that allows creation of a modular, adaptable, scalable system able to be transported and stored in a very compact lightweight package.   Cradle Inflatable Panels: Drop-stitch ultra-lightweight double-sided fabric has the ability to be inflated and retain a flat panel shape which will enable a system with lower cost, simplify assembly, and minimize storage volume. Drop-stitch, when inflated, offers structural integrity to the system allowing our approach to be lightweight yet structurally robust capable of being used in open seas up to sea-state 3. Cradle structure:  The main structure of the MUVRs cradle will be a rapidly erectable aluminum frame.  Initial investigation into the loads indicate that the drop-stitch inflatables will require structural reinforcement to maintain rigidity in order to be effectively maneuvered by the thrusters.  The structure will also be designed to be modular such that the system can be adapted to a range of UV platforms.  The cradle structure will also include structural interfaces to secure the MUVRs to the well-deck. ROTs: COTS thrusters will be remotely controlled from the host platform to enable the MUVR to maneuver to and from the UxV. The thrusters will be rigidly connected to the cradle structure using quick disconnects so they can be arranged according to the UxV to be launched and recovered. The control system will use cameras, lights, sensors, and in-house developed software that will aid the operator in aligning the cradle to the UxV during recovery.  Communications between the MUVR and host platform will be accomplished using a COTS receiver and transmitter. .
