What is CPACS?

The Common Parametric Aircraft Configuration Schema (CPACS) is a data definition for the air transportation system. CPACS enables engineers to exchange information between their tools. It is therefore a driver for multi-disciplinary and multi-fidelity design in distributed environments. CPACS describes the characteristics of aircraft, rotorcraft, engines, climate impact, fleets and mission in a structured, hierarchical manner. Not only product but also process information is stored in CPACS. The process information helps in setting up workflows for analysis modules. Due to the fact that CPACS follows a central model approach, the number of interfaces is reduced to a minimum.

Introduction of regular developer meetings

2021 developer meeting

On November 18, we successfully kicked-off a new format of regular meetings concerning CPACS development. A group of 15 participants from university, research institutions and industry discussed how the meetings can be organized efficiently. We agreed on regular meetings at intervals of 13 weeks, in which general topics concerning CPACS …
