In this project two fe models for counter-rotating open rotors made from composites were needed. Before generating these models, a structural design was necessary. IBK is an SME with a long tradition in both structural mechanics and aerodynamics. Consequently, our customers come from areas where both parts of our knowledge are needed, which is among the aviation industry and the turbine industry. IBK therefore drew on long years of experience in the field that was needed.

Therefore, a project was proposed, in which the disciplines of designing rotating devices (in this case an open rotor) and designing parts with composites (in this case the rotor blade) are united. IBK started with an detailed analysis of the design problem of the rotor-blade, propose and discuss solution with the JTI-Consortium and develop a composite-design, using a modern, state of the art failure criterion which promises a high level of quality for the design. All relevant steps were performed in close cooperation with the contractor, in order to ensure that all input for the project is accounted for.
