"In this project two fe-models for counter-rotating open rotors made from composites are needed. Before generating these models a structural design is necessary. IBK is a 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 the turbine industry. IBK can therefore draw on long years of experience in the field that is needed here. Therefore a project is 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 will start 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 will be performed in close cooperation with the contractor, in order to ensure that all input for the project is accounted for."
