Overview

• ATR was selected to lead the HERACLES and DEMETRA projects using an ATR 72-600 testbed to integrate hybrid‑electric propulsion, high‑performance batteries, and a thermal engine compatible with 100% Sustainable Aviation Fuel, aiming to fly by 2030.
• The selected programmes are slated to begin early next year, with initial demonstrator flight tests envisioned for 2028–29.
• The funding round totals €945 million, including €378 million from the European Union, with €144 million earmarked for regional aircraft technologies and fast‑track initiatives such as Cryostar to study liquid hydrogen tank crashworthiness.
• Clean Aviation is targeting up to a 30% fuel‑efficiency improvement for a next‑generation regional aircraft with an entry‑into‑service goal of 2035.
• Additional awardees include Airbus, Pratt & Whitney Canada, Safran and Rolls‑Royce for work on hybrid‑electric architectures, integrated systems and open‑fan engine demonstrations.
