In PALOMA (2021-2023), ATHERM worked on heat pipes and passive ventilation for aircraft engine cooling, directly applying passive thermal control to an aerospace-grade demonstrator.
ATHERM
French thermal engineering SME developing passive heat management systems and SMA actuators for aerospace applications.
Their core work
ATHERM is a French engineering SME based near Grenoble specializing in thermal management systems and heat transfer technologies. Their work centers on passive thermal solutions — systems that manage heat without active power consumption — with demonstrated expertise in heat pipes, phase-change materials, and shape memory alloy actuators. In the PALOMA project they developed a passive ventilation system for aircraft engine nacelles, combining thermal engineering with lightweight mechanical actuation for next-generation UHBR turbofan engines. The company name itself reflects their core identity: thermal engineering is not a side competence but their foundational discipline.
What they specialise in
PALOMA keywords include 'shaped memory alloy' and 'passive actuator', indicating ATHERM has hands-on experience coupling SMA-based mechanical actuation with thermal regulation.
Participation in GrapheneCore1 (2016-2018) — the EU Graphene Flagship — most plausibly reflects ATHERM contributing thermal conductivity or heat dissipation expertise to the materials program.
PALOMA explicitly targeted UHBR engine nacelle integration, placing ATHERM within the Clean Sky 2 / JTI aerospace supply chain for thermal and ventilation subsystems.
How they've shifted over time
In their earliest H2020 involvement (2016–2018), ATHERM operated at the materials science frontier — participating in the massive GrapheneCore1 Flagship where the context was fundamental research into graphene and 2D layered materials. By 2021–2023, the focus had shifted sharply toward applied aerospace engineering: heat pipes, engine cooling, nacelle integration, and passive actuators for Ultra High Bypass Ratio turbofans. This is not a random jump — it suggests ATHERM used the graphene program to explore next-generation thermal materials, then channeled that knowledge into concrete aerospace product development. The trajectory points toward a company moving from materials-level research toward system-level engineering with real hardware demonstrators.
ATHERM is moving toward industry-ready thermal solutions for aviation, with PALOMA's prototype and demonstrator outputs suggesting they are positioning for product commercialization in next-generation aircraft engine thermal management.
How they like to work
ATHERM has participated exclusively as a consortium partner across both projects — they have never led a project as coordinator. Both projects were large multi-partner consortia: GrapheneCore1 was the EU Graphene Flagship with hundreds of participants, and PALOMA was a Clean Sky 2 initiative with a broad industrial consortium. This indicates ATHERM is comfortable contributing deep specialist expertise within large, well-organized programs rather than building and managing consortia themselves. For a future partner, expect a focused technical contributor who delivers on a specific workpackage rather than a project architect.
ATHERM has accumulated 195 unique consortium partners across 24 countries — a disproportionately wide network for just two projects, almost entirely explained by GrapheneCore1's scale as the EU's largest research flagship. Their geographic reach is genuinely European, but their deep bilateral relationships are harder to infer from this data alone.
What sets them apart
ATHERM sits at an unusual intersection: a small French engineering firm with both flagship fundamental research credentials (EU Graphene Flagship) and hands-on aerospace system engineering experience (Clean Sky 2 / PALOMA). Most SMEs at their scale operate in one lane; ATHERM spans from materials science to flight-ready demonstrators. For consortium builders in aerospace or advanced thermal systems, they offer specialist depth without the overhead of a large contractor, and their Grenoble location places them within one of Europe's densest deep-tech ecosystems.
Highlights from their portfolio
- PALOMAAn applied aerospace engineering project with a physical demonstrator outcome, showing ATHERM can deliver from concept through prototype — the strongest evidence of their real-world engineering capability.
- GrapheneCore1Participation in the EU Graphene Flagship — one of Europe's largest and most competitive research programs — establishes ATHERM's credentials in advanced materials and connects them to a 195-partner international network.
