Heart Aerospace ES-30 hybrid-electric regional airliner
Heart Aerospace's switch to an independent hybrid-electric propulsion system for its ES-30 aircraft has prompted design changes to the 30-seater.

Heart Aerospace plans to reveal a technology demonstrator for its ES-30 hybrid-electric regional airliner in the fall. The Sweden-based company has changed the architecture for the 30-seater’s propulsion system to an independent hybrid configuration it said will allow more missions to be flown in all-electric mode.

Instead of the earlier series hybrid configuration, the aircraft will now use a pair of as-yet-unspecified turboprop engines installed on the outboard section of the wing and two electric motors inboard. The company confirmed the decision to drop the series hybrid configuration with a turbogenerator in May, leading to other design changes including moving the battery bay from the lower fuselage and removing winglets and strut-braced wings.
