ATD3 Workshop 2026

AeroThermoDynamics and Design for Demise (ATD3) Workshop

ATD3 workshop is a long-standing European forum which aims at fostering technical and scientific discussions, collecting and disseminating knowledge, proposing new topics and activities, and contributing to planning efforts, including roadmap definition and coordination.

The main objectives of the ATD3 workshop are to:

• Establish a framework for the verification, validation, and comparison of numerical methods used in space object reentry simulation tools.
• Disseminate recent scientific and technical results within the ATD3 community, which includes academic participants (in particular PhD students) as well as experts from industry.
• Coordinate and discuss future activities, with the goal of gathering expert perspectives from both academia and industry on forthcoming developments in the fields of aerothermodynamics and design for demise

The workshop addresses a broad range of topics related to space object re-entry aerothermodynamics and design for demise, including:

• Improvement, verification and validation of numerical methods for simulating the destructive re-entry of space vehicles, including verification of design for demise solutions;
• Modelling of ablation and material response under re-entry conditions;
• Fragmentation and break-up modelling of re-entering space objects;
• Experimental capabilities, testing facilities and measurement techniques supporting re-entry analysis;
• Characterisation of materials relevant to atmospheric re-entry;
• Investigation of drag-driven de-orbiting solutions.

ATD3 2026: preliminary information

The next ATD3 workshop will be held from June 17^th to June 19^th 2026 in Toulouse (France). The event will be hosted at the Cité de l’Espace (Space City).

The format is a sequential list of presentations of about 20 minutes each, with 5 minutes brief Q&A session per presentation.

We are proud to have HyFAR-ARA as our official sponsor, whose support makes this event possible. Thank you for partnering with us to create an exceptional ATD3 experience.
