Collaborative design is a current issue in aviation industry where intellectual property rights of individual companies prohibit a common evaluation model. State of the art approaches based on nested local optimisation loops are not sufficient if time-consuming component analyses are involved. A new approach for collaborative design is developed where the overall optimisation of a complex system is split into subsystem optimisation problems. Coupling parameters are treated as local design variables and only optimal coupling parameters are exchanged regularly. Application to a test example shows a huge time reduction and improved probability for finding the global optimum. Advantages are also demonstrated for an industrial design task.

The design of industrial gas turbines is a highly complex task where the engineer typically run a lot of design cases intuitively and manually in order to find only acceptable design solution which is usually a time consuming procedure.

The paper deals with aerofoil adaption of a blisk within a multi-criterion optimisation loop. Blisks are more sensitive to external excitation since mechanical damping is very low. Thus stronger limits have to be applied which are hard to be fulfilled and hence it requires the use of numerical optimisation. Combination of 2D CFD and FEM in a common optimisation loop to re-design a given blisk. Determination of relevant features for improving blisk endurance. Modern process integration and multi-criterion optimisation tools in combination with today's increased computational power allow to perform mulitphysics design even in the case of complex industrial design tasks.

This motivates the need of robust design against such parameter uncertainties. A specific parametrisation is established combining deterministic, velocity dependent steering control parameters with partly uncertain, velocity independent vehicle parameters for simultaneous use in a numerical optimisation process. Model-based objectives are formulated and summarized in a multi-objective optimisation problem where especially the lateral steady state behaviour is improved by an adaption strategy based on measurable uncertainties. The normally distributed uncertainties are generated by optimal Latin hypercube sampling and a response surface based strategy helps to cut down time consuming model evaluations which offers the possibility to use a genetic optimisation algorithm. Optimisation results are discussed in different criterion spaces and the achieved improvements confirm the validity of the proposed procedure.
