Redefining aviation propulsion

H55 Ambassadors

H55 Ambassadors isn’t just a community — it’s a mission to reshape aviation.
Clean, quiet flight is no longer a dream, it is flying today.

Why should you become an H55 Ambassador?

Ambassador Only Events

Collaborate with aviation enthusiasts from around the world and gain access to ambassador only reunions.

Access to Knowledge

Learn from our expertise in engineering, aircraft integration, certification, and startup development.

Redefine the Impossible

Be the voice of aviation’s next revolution — where technology, sustainability, and purpose take flight.

Ambassador Role

Join the Mission. Champion the Future of Clean Aviation with H55.

Are you ready to be part of something revolutionary? The H55 Ambassadors program is for those passionate about aviation, clean technology, and driving real change. Whether you're a pilot, educator, student, or just someone who believes in transforming flight, join a global community bringing electric flight to life. Be the voice of innovation. Be the force for change. Join us.

Responsibility

To be an H55 Ambassador, the only requirement is to help spread the word about H55 at least once a month—whether through a presentation, social media post, event, or any creative initiative that shares our mission.

Are you a pilot, flight instructor, or flight school manager?
Bring H55’s electric propulsion technology to the cockpit and inspire the next generation of aviators.

Your role:
Organize a joint event with H55 at your flight school, share updates through flyers or emails, and keep your aviation community informed about the latest H55 developments.

Are you an influencer?
Help shape the future of clean aviation by sharing H55’s mission with your audience.

Your role:
Post about H55 on your preferred platform — whether it’s YouTube, Instagram, LinkedIn, or Facebook.

Are you a student in engineering or aviation?
Be the voice of electric aviation on your campus and help build awareness around H55’s mission.

Your role:
Promote H55 at least once a month through your campus network — put up flyers, share updates with student clubs, or give a quick presentation about H55 in class.

Are you a professor or STEM educator?

Bring H55’s electric propulsion technology into the classroom and inspire the next generation of engineers.

Your role:
Lead one classroom discussion per semester about H55, explore our technology with your aerospace or aviation students, and help connect curriculum to real-world innovation in clean aviation.

Others build. We master.
At H55, electric propulsion is our expertise — not just our product.

We don’t only certify — we collaborate directly with certification authorities.
We don’t only develop cutting-edge propulsion — we partner with aircraft manufacturers to fully integrate our technology.
We don’t only engineer — we build and operate our own test benches to validate every component.
We don't only deliver a product we deliver a full scale solution of systems integration and certification.
