Abstract: Today, the preliminary design process of power system architectures of civil aircraft is
characterized by the separation into air transport association chapters. However, the complexity
of an aircraft energy network and the large number of influencing design parameters and system
interfaces require a common and transparent process if one is aiming at a meaningful evaluation
of different system architectures with regard to overall aircraft efficiency. The variety of possible
solutions requires a flexible tool that enables the system designer or aircraft architect to analyse
the impact of system architecture changes at the aircraft level and the impact of aircraft level
changesonsystem design.Theoutline of a simulation framework that fits these needs is presented
in this paper.
Keywords: aircraft power system architecture, preliminary design, power management,
modelling and simulation
1 INTRODUCTION
Energy saving becomes more and more important in
a highly competitive market with regards to increasing
fuel prices and the increasing importance of environmental
friendly transport. Therefore, it is important
to analyse the influence of aircraft systems on overall
aircraft efficiency, fuel consumption, and direct
operating costs already in the pre-design phase of the
aircraft development.
Today, the aircraft system pre-design process is
characterized by the separation into Air Transport
Association (ATA) chapters.Thus, each system domain
takes into... [continues]
