Development of robust design systems
The main objective of this WP is the introduction of probabilistic simulations into the software systems supporting the
design optimisation and associated decision process. Most of design procedures currently used by the aerospace
industry apply complex simulation codes applied in a deterministic way. However a number of sources of
uncertainties exists both in the accuracy of the predictions as well as in the definition of the actual operating conditions
of a given product. It is therefore important that a simulation based design procedure should take this situation into
account and provide the engineer with tools capable of an estimate of the “stability” of the predictions as well as
estimation of “simulation” margins. Robust design is defined as the design process by which the dependence on
sensitive parameters is minimized and this can be achieved through the introduction of the non-deterministic
uncertainty quantification of the simulation outputs in the design optimisation methods and algorithms.
The methods developed in this WP will be applied to representative design objectives for airfoil and wing design, as
well as for turbomachinery blade shape robust optimisations, by the industrial partners supported by the software
oriented SME’s, who are strongly involved in this WP.
