The companies signed the partnership at Bern Airport, where H55’s certified aviation batteries were confirmed as the core system for Smartflyer’s SF-1.

Raytheon Technologies has achieved the successful first engine run of its regional hybrid-electric DHC Dash 8-100 flight demonstrator, marking a key milestone towards flight testing, targeted to begin in 2024.

With the DOA and POA secured, H55 is well positioned to receive a type certificate for its 100kW electric propulsion system by the end of 2023.
