Australian Company Launched the Unmanned Surface Boat with Composite Materials

Australian Ocius Technologies has released its 5.6m BluebottleStinger Unmanned Surface Vehicle (USV). This autonomous UAV boat is designed by a diverse team of experts, including Ocius Technology, One-2-Three Naval Architects and Composite Materials Consulting Group (CCG). With decades of experience in solar-assisted sailing, Ocius developed the BluebottleStinger surface boat for continuous unattended monitoring on oceans.

This USV can obtain solar energy through solar panels and collect wind energy through the rigid wing. The unique rudder of the boat will produce the forward power from the wave energy of the water. All these technologies make the boat completely autonomous, and maintain the average speed of 4 knots and carry more than 100 kg of payload.

The USV is designed to automatically deploy a sonar array that can monitor sub-sea traffic while capturing video images from the sea. A team of USVs collaborate with a wide range of marine areas with only minimal monitoring staff, and they only need to do some regular maintenance. The benefits of service costs are obvious.

To build a boat that can operate efficiently, it is important to reduce the weight of the hull, but also to maintain durability at all sea conditions. In response to these challenges, CCG chose DIAB's HM80IPN foam for hull and keel shells, as well as Matrix7-7 for deck shells and removable hatchways.

The structure is designed by Australian CCG Company according to ISO12215A standard and is made by Australian builder Steber International Company using hand-paste vinyl ester resin and E glass fiber reinforced material. (More information about the fiber testing instruments, checking SatatonMall for more details.) Prototype hull and keel shell with a grid of folding foam board temporary forming, and then apply the outer skin and reinforced materials, and the shell removed from the mold, apply the inner skin, made of a final rigid shell.

The wing sails were constructed using non-structural EPS foam as a model attached to the hollow carbon mast tube. In order to create a support structure for the model, the matrix bars made with Matrix7-7 foam are embedded in EPS at 550 mm. These tendons allow the model to be well attached to the mast and lightweight carbon fiber skin reinforcement.
