EGILE CORPORATION XXI SL

Their core work

Egile Corporation XXI is a small Spanish engineering company based in the Basque Country that specialises in engine and combustion technology for the aeronautics sector. They contribute as a technical specialist to aircraft engine development programmes, specifically within the Clean Sky 2 Joint Undertaking's Engine Integrated Technology Demonstrator (ITD). Their work spans combustion system development and the assembly or testing of engine demonstrators — the physical prototypes built to validate next-generation aviation propulsion concepts. With both recorded projects sitting inside the same EU aeronautical clean-technology programme, their commercial identity is tightly coupled to the aerospace supply chain in northern Spain.

What they specialise in

How they've shifted over time

In their first recorded project (2018–2019), the keywords are foundational — engines and combustion — suggesting a role focused on core thermodynamic or mechanical contributions to an engine module. By their second project (2020–2024), the keyword set expands to include 'CS2' and 'demonstrators', signalling a shift toward integrated prototype validation rather than component-level work alone. The trajectory is narrow but consistent: deeper involvement in the demonstrator phase of the same Clean Sky 2 engine programme, rather than any diversification into new sectors or technologies.

They appear to be moving further into the demonstrator and validation stage of aeronautical engine development, making them a plausible partner for future Clean Sky / Clean Aviation demonstrator projects requiring combustion or engine assembly expertise.

How they like to work

Egile has never led an H2020 project — both participations are as a consortium member, consistent with a specialist supplier role within large, programme-managed aeronautical consortia. The 41 unique partners across 12 countries suggest they work inside broad, multi-partner programmes rather than in tight bilateral relationships. This is typical of Clean Sky 2 dynamics, where an SME contributes a defined technical work package and has limited direct influence over consortium structure.

Despite only two projects, Egile has been exposed to 41 consortium partners spanning 12 countries — reflecting the large, Europe-wide consortia that characterise Clean Sky 2. Their network is aeronautics-specific and centred on the Engine ITD community.

What sets them apart

Egile is a Basque Country SME with demonstrated access to the Clean Sky 2 Engine ITD — one of the most competitive and technically demanding aeronautical R&D programmes in Europe. That access is not trivial for a small company, and it signals recognised technical capability in combustion or engine manufacturing that larger prime contractors are willing to contract. For a consortium builder, they offer a route into a proven Spanish aerospace SME already cleared for CS2-level deliverables, without the overhead of a large industrial partner.

Highlights from their portfolio

• ENG GAM 2018
  The larger of the two contracts (€48,220), representing their entry into the Clean Sky 2 Engine ITD and establishing their credibility as a combustion technology contributor.
• GAM-2020-ENG
  Spans 2020–2024, making it their longest and most recent engagement, and the first to include demonstrator work — signalling a step up in integration responsibility.
