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.
CPACS is available as Open Source and we encourage anyone to make use of it. If you are applying CPACS in a scientific environment and publish any related work, please cite the following artice:

To celebrate the 20th anniversary of CPACS, we are inviting researchers and engineers from industry, small-and medium-sized companies, research organisations, academia and think-tanks to join our event to:
This year marks the 20th anniversary of CPACS as a common language in aircraft design that has become a de facto standard for data exchange collaborative in research and beyond. This milestone was highlighted during a dedicated session at the Architecting Future Aviation Symposium, hosted by the German Aerospace Center …
At the 14th EASN International Conference on “Innovation in Aviation & Space”, held from 8–11 October 2024 in Thessaloniki, Greece, CPACS played a central role in a series of sessions led by the EU-funded IMPACT MONITOR Project. The conference served as a key platform for sharing digital engineering frameworks that …
At the 73rd Deutscher Luft- und Raumfahrtkongress (DLRK), held from 30 September to 2 October 2024 in Hamburg, the aerospace modeling community celebrated a major achievement: 20 years of CPACS (Common Parametric Aircraft Configuration Schema). This anniversary marked two decades of progress in advancing standardized, parametric design approaches for complex …
Just in time for Christmas, we present CPACS v3.5. Take a look at www.cpacs.de and GitHub for:

Dear CPACS developers,
Next week Thursday, November 17, there will be our next regular developer meeting. Please find all information in our inviation and agenda.
At the DLRK congress in Dresden, the prototype of a new software library, called cpacsLibrary, was presented under the title:
** Development of a Software Library for Performant and Consistent CPACS Data Processing **
The Common Parametric Aircraft Configuration Schema (CPACS) is increasingly used as a standard for data exchange in …
It's release time again! We are happy to announce the v3.4 release. Take a look at www.cpacs.de and GitHub for:
