Current Projects
01
Calamari
Full project title: Coated riblets with antifouling effect for maritime applications
Program: Beyond Europe 2018 | FFG
Partners: JOANNEUM 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 works on this problem in a triple approach:
The production of
- flow resistance-reducing Riblet patterns
- in mechanical, surface energy adapted
- and non toxic metal oxide antifouling UV-curing resins on flexible foils

RiSPECT
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.
03
ReSiSTant
Full project title: Large Riblet Surface with Super Hardness, Mechanical and Temperature Resistance by Nano Functionalization
Program: H2020
Partners: RINA Consulting – D’Appolonia S.p.a. | Fraunhofer Gesellschaft zur Förderung der angewandten Forschung E.V. | Fundacion Prodintec | General Electric Deutschland Holding GmbH | Lufthansa Technik AG | Man Diesel & Turbo Schweiz AG | Nanto Cleantec IS | Rheinisch-Westfälische Technische Hochschule Aachen | Technische Universität Graz
Project webpage: resistant-project.eu
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.
