Blue Spirit Aero

Blue Spirit Aero is a French aircraft company based in Toulouse, France. It develops the Dragonfly, a hydrogen-electric aircraft. The site says the company uses hydrogen fuel cell technology and electric motors to support sustainable aviation.

The Dragonfly design uses distributed propulsion and a blown-wing effect. The site lists a development path. It starts with a preliminary design phase in 2021, followed by a digital twin in 2022, a 1:4 scale flying demonstrator in 2023 and a heat exchanger test bench in 2024.

A full-scale ground demonstrator was rolled out in 2025 at the airport in Le Mans, France. It was installed next to a gaseous hydrogen refuelling station. The site says it supports ground tests of key systems and prepares the aircraft for its first flight.

Ballard Power Systems supplies the hydrogen fuel cell system. Daher works on structural parts. SOBEN designs and tests the landing gear. Thales handles control of the distributed electric architecture.
