Optimizing systems architectures at aircraft level

Aircraft systems are key drivers of innovation in aircraft design and heavily influence overall mass, fuel consumption, operating costs and reliability. Particularly with new technologies such as within the More Electric Aircraft, it is crucial to analyze and optimize systems at a global level to minimize the risk of design inconsistencies or unforeseen behavior in the integration phase.

Our systems architecture design software Pacelab SysArc supports investigations at the aircraft level with a fully-fledged preliminary aircraft design environment. Delivering instant feedback on the global impact, costs and benefits of architectural alternatives, Pacelab SysArc provides a reliable framework for assessing new technologies and making investment or development decisions.

What Our Customers Say
  • "Pacelab APD/SysArc enables us to model and evaluate a much larger number of concepts pushing the boundaries of the design space. The software also makes it easy to share project data, geometries and methodology with academic and industry partners all over the world."

    Christopher Jouannet, Principal Engineer Advanced Design SAAB
  • "With SysArc and APD Safran is able to define, analyse and optimize fully integrated systems in an accurate fashion. The suite allows for localized sub-system/architecture assessments together with an understanding of the aircraft level outcome.
    Safran studies range from gauging the impact of novel engine off-take configurations to investigating the feasibility of advanced dual-energy propulsion concepts."

    Dr. Yann Fefermann, Advanced Systems Architecture and Integration Specialist Energy & Propulsion Department, Safran Tech
