Full project title: Coated riblets with antifouling effect for maritime applications

Program: Beyond Europe 2018 | FFG

PartnersJOANNEUM RESEARCH Forschungsgesellschaft mbh | MicroTau Pty Ltd

Information: Due to environmental bans, more and more biocide coating strategies are disappearing in the marine industry. Nevertheless, it is still a major concern to reduce fuel consumption and increase material life by reducing hydrodynamic resistance. The Calamari project aims at solving this problem by producing modified Riblets for maritime applications. The goal is to combine drag reduction and antifouling properties. During the course of coating development for the antifouling, surface energy is reduced by adding nontoxic nanoparticles containing metal-oxides. Riblet optimization and testing for maritime applications will be performed.



Full project title: Riblet Inspection and Efficiency Assessment Technology

Program: Beyond Europe 2018 | FFG

Partners: AIT Austrian Institute of Technology GmbH – Center for Vision, Automation & Control | TU Graz – Institut für Softwaretechnologie | Universität Wyoming – Institut für Maschinenbau

Information: The aim of the RiSpect project is to provide a basis for an automated system to estimate the quality of Riblet surfaces based on image data, so that the overall costs for quality management measures when using Riblet surfaces are reduced. 
For the first time, machine learning, especially the so-called Deep learning, used to classify and predict the quality of Riblet Surfaces.



Full project title:  Large Riblet Surface with Super Hardness, Mechanical and Temperature Resistance by Nano Functionalization

Information: The aim of the ReSiSTant project is the optimization micro- and nanostructured surfaces of two industrial pilot lines; on the one hand, these newly developed surfaces are to be implemented on aircraft turbines, on the other hand on industrial compressors. 
These could have a positive impact on efficiency and Co2 emissions, and thus also on the economy and ecology.
