Design and construction of a biologically inspired hydrodynamic hull for the OpenROV
So far no information materials were provided for this event. Please contact the organizer directly for further information.
The OpenROV 2.7/2.8 was modified for use as an underwater camera platform with low drag force. Using the Techno-Pull-Principle organisms were selected to serve as inspiration for hull shapes for the planned application. The hulls were scaled down and their hydromechanic properties were analysed by wind tunnel and PIV-measurements. A hull modelled on the carapace of the green sea turtle Chelonia mydas was determined as the design best suited. A full-scale version of this hull was produced by 3D-printing. In wind tunnel tests with the full-sized ROVs the drag force in the relevant Reynolds-Number range was shown to have been reduced by up to 77. 6 %. In a functionality test the modified ROV reached up to 94 % higher speeds with the same motor settings. The new hull also allows the integration of additional functional components without negatively affecting the surrounding flow.
