The main objective of the work presented is to help architects to develop solutions based on unconventional approaches and to do so, a conceptual framework is presented. The whole framework starts from the requirements and the use cases capture and the Architectural Object database construction. Then it continues with an architectural automated synthesis. The framework uses concepts taken from the System Engineering field and the graph theory and can be applied to several system to design of different domains. The helicopter dynamic systems are multi-domain and totally encounter the scope of the framework.
