Multidisciplinary Optimization of Aircraft Vehicle System for Conceptual Analysis

An aircraft is a multifaceted product which requires cooperation between different engineering domains. Therefore, design of an aircraft is essentially a multidisciplinary activity with necessity of integrating different design tools to get an optimized product. At Linköping University, a design framework is being developed to assist in the evaluation and optimization of various aircraft vehicle system architectures with the help of integrating a geometric, aerodynamic and dynamic models early in the conceptual design phase. This framework helps to identify a preliminary system concept for an energy optimized aircraft architecture with the focus on more electrical aircraft. As a case study the performance and geometrical aspects of an EMA (Electromechanical actuator) are evaluated and optimized.
