Passenger flow simulation PAXelerate in OpenCDT

During the early stages of conceptual aircraft design processes, it is essential to enable a holistic view on driving design parameters. OpenCDT, as an open-source framework, allows the integration of design data and functionality from existing software tools, supporting the collaboration between discipline teams and being flexible enough to be adapted for designing unconventional aircraft concepts. As an ultimate goal, a complete design process with a variable grade of detail due to the flexible embedding of internal and external methods is supported. In addition, seamless integration of additional tools is provided to enable analyses in direct communication with the aircraft design task.

Fully embedded into the OpenCDT framework, the open-source passenger flow simulation PAXelerate assesses cabin layouts as one of the major aircraft design drivers. The simulation bases on a microscopic approach applying agent-based modelling techniques. Especially advanced aircraft concepts and cabin layouts have not been put under a quantified assessment regarding their operational performance, even if they offer huge potentials for improvement with respect to overall process time. Trade studies regarding passenger composition, anthropometric diversity, airline boarding strategies and aircraft conceptual modifications, such as the optimisation of door dimensions and positions, becomes feasible. The simulation results permit insights into different cabin design approaches in terms of passenger ingress and egress performance during the early stage of a conceptual aircraft design process.
