How Bull's New Supercomputer Powers Airbus' Data Centres

French computing company Bull has delivered a new supercomputing infrastructure for aerospace giant Airbus, with the project focusing on two high-performance modular data centres in France and Germany.

The infrastructure was inaugurated with the launch of two new supercomputers and their respective modular data centres in Toulouse, France in 2025 and Hamburg, Germany in 2026.

“This long-term strategic and technological collaboration highlights the critical role of HPC in driving innovation and breakthrough programmes across the aerospace and manufacturing industries,” says Martin Matzke, Head of Central Europe and Northern Europe at Bull.

The deployment reflects how data centre infrastructure is becoming more important for industries handling large-scale engineering and simulation workloads.

Airbus is using the systems to accelerate digital aircraft testing before physical prototypes are built.

Engineers create virtual aircraft models and run simulations covering aerodynamics, acoustics and structural stress analysis.

The increased computing capacity means Airbus can now run three times as many simulations simultaneously, helping reduce development timelines while maintaining safety and performance standards.

The systems are also designed to support several aircraft programmes at once, allowing Airbus to continue refining existing fleets while developing future aircraft technologies.

Modular Data Centres for HPC

Under the multi-year contract, Bull supplied Airbus with a turnkey high-performance computing environment that includes compute infrastructure, storage systems and the physical data centres themselves.

The infrastructure is delivered through a flexible service-based approach instead of a traditional ownership model.

Bull designed the data centres using modular architecture, with prefabricated sections assembled and tested at the company’s production facility in Angers, France.

The supercomputing equipment is fully integrated into the modules before shipment, reducing deployment complexity once delivered onsite.

After arriving at Airbus facilities, the modules are connected together to create operational high-performance data centres.

Bull says the modular approach helped accelerate deployment schedules while also simplifying scalability for future computing expansion.

Bull delivered the first supercomputing system for Airbus in Toulouse 14 months after the contract agreement was signed. The Hamburg deployment in 2026 marked the completion of the programme.

“Our collaboration with Airbus to deliver a turnkey HPC solution is a cornerstone for Bull and our high-performance computing business,” says Bruno Lecoint, Head of HPC, AI and Quantum Computing at Bull.

“Being recognised as an HPC strategic partner by a global, world-renowned industry player is an honour for our teams.”

Cooling and Energy Efficiency

The project also places significant emphasis on data centre energy efficiency.

Bull equipped the systems with its direct liquid cooling technology to manage the thermal demands associated with large-scale supercomputing infrastructure.

The liquid cooling system is designed to reduce electricity consumption compared with conventional cooling approaches while supporting higher-density computing environments.

The infrastructure also incorporates heat recovery capabilities.

Instead of allowing excess heat generated by the supercomputers to go unused, the system captures and redirects it to heat neighbouring buildings.

As demand for compute-intensive workloads continues to grow across aerospace and manufacturing, the Airbus deployment shows how modular data centres and advanced cooling technologies are becoming key to modern HPC infrastructure strategies.
