Abstract	On the one hand the diversity of rotorcraft concepts is very rich, on the other hand the extent of their applications is very wide. Then a key question is raising: What is the most suitable concept facing a number of missions and specifications ? For answering, models and methods are required for predicting and evaluating the flight performances and environmental impact of rotorcraft. The project «Concepts of Rotorcraft Enhanced Assessment Through Integrated Optimization Network» (C.R.E.A.T.I.O.N.) aims at developing a multi-disciplinary and multi-level modelling calculation chain. The multi-disciplinary feature comes from the involvement of different disciplines in rotorcraft design. The multi modelling levels are defined to allow the evaluation of any rotorcraft concept whatever the level of details available in the description data. The present thesis is part of this project. First steps are the implementation of statistical models able to initialize the rotorcraft presizing from some specifications, the development of an analytical code that evaluates flight performances and its integration into the multidisciplinary calculation chain. A preliminary design conception chain using multidisciplinary optimization is setup and applied to a practical case showing its efficiency as presizing methodology. For this purpose multi-objectives exploration algorithms and decision aid methods to select a best compromise solution are also studied. The exploration of databases and creating response surface models are other themes explored in this thesis.
