Our hybrid-electric propulsion system uses a combination of a turbogenerator and battery packs to power the aircraft's electric motors. The turbogenerator is sized for cruise, while the battery boosts power for takeoff and landing. This way, the turbogenerator can be small and always operates at its most efficient operating point.
This reduces fuel burn and lowers maintenance cost. Operators can choose to charge the battery in flight via the turbogenerator or re-charge on the ground where charging infrastructure is available. However, charging infrastructure is not required. The turbogenerator supports up to 100% sustainable aviation fuels and future use of eFuels or hydrogen for zero-emissions flight.
