Some meta-modeling and optimization techniques for helicopter pre-sizing.

Abstract : Optimization and meta-models are key elements of modern engineering techniques. The Multidisciplinary Design Optimization (MDO) allows solving strongly coupled physical problems aiming at the global system optimization. For these multidisciplinary optimizations, meta-models can be required as surrogates for complex and high computational cost codes. Meta-modeling is also used for catching general trends and underlying relationships between parameters within a database. The application of these mathematical techniques to the pre-design of rotorcraft is well relevant. Indeed rotorcraft pre-sizing is a multidisciplinary issue involving flight dynamics, aerodynamics, power generation, structures, ... Moreover the rotorcraft databases requires meta-modeling techniques to be useful. This paper presents several techniques studied by ONERA in the C.R.E.A.T.I.O.N. project. The practical case considered here deals with the helicopter main rotor optimization.
