Ampaire’s Eel demonstrator flies record endurance flight


Ampaire’s Eel demonstrator has set a new endurance record for a hybrid-electric aircraft, according to founders. 

The aircraft flew in the skies above Camarillo, California for exactly 12 hours, and landed with over 2 hours of fuel and battery reserves remaining. The flight is being heralded as a “crowning achievement”, closing out a year marked by flights in Canada, Alaska, Arizona, and California.

“Through this groundbreaking mission, Ampaire has shattered the conventional boundaries of electrified flight, underscoring our relentless pursuit of transformative vehicle performance and commercial utility,” said Ampaire CEO Kevin Noertker. 


“Our unique hybrid electric solutions deliver unparalleled operating economics and unlock endurance and operational flexibility critical to our customer’s needs. The indomitable spirit of innovation within the entire Ampaire team propels us forward on this journey toward a sustainable future. It is a testament to our lasting commitment to pioneering excellence,” he added.

The Eel demonstrator aircraft has been pivotal in advancing high-powered electronics, inverters, motors, and associated systems. The aircraft has served as the backbone for Ampaire’s innovative AMP-H570 AMP Drive hybrid-electric propulsion unit currently flying in Ampaire’s Eco Caravan. The unit has achieved a 50% to 70% reduction in fuel consumption and emissions compared to traditional Pratt & Whitney PT6 turboprop engines.
