Overview
- H55 has delivered certification-grade propulsion battery modules to Pratt & Whitney Canada for use in the RTX Hybrid‑Electric Flight Demonstrator, where the units will be integrated for flight testing.
- Pratt & Whitney Canada said H55’s ability to supply aviation-grade battery systems inside a rigorous certification and production framework is an important enabler for demonstrating hybrid‑electric propulsion in flight.
- H55 reports it completed regulator-required propulsion battery certification testing before any other company in the sector and says its manufacturing runs in a regulator‑approved facility produce production‑conforming systems.
- The company cites more than 2,000 hours of fully electric flight across multiple programs with no battery-related incidents and describes a safety approach that includes independent cell characterization and redundant safety architectures.
- H55 frames the delivery as a move from development to commercialization that could speed OEM and insurer confidence and help scale certified battery suppliers into hybrid‑electric commercial aviation, defence and UAV markets.
