The ES-30 represents the first product in Heart Aerospace's electric aircraft lineup. The Swedish-based startup originally drew up plans for a 19-seater all-electric solution intended for regional use - the ES-19 - but switched to 30-seat passenger hauler of hybrid-electric propulsion. The aircraft is expected to enter service sometime in 2028 and, should the project fulfill its intended design goals, will challenge the hold of popular twin-engined turboprop types operated around the world.

Partners of the ES-30 program include United Airlines, Air Canada, and Saab.

Overall, the aircraft has a conventional external configuration which sees a side-by-side cockpit aft and over a short nosecone The fuselage is cylindrical and dotted with porthole-style viewing windows. The tail is elevated and carries a single large-area vertical fin with high-mounted "T-style" horizontal tailplane arrangement. Four propeller units are seated across the high-mounted mainplanes, the wings capped by upturned winglets. The mainplanes are braced at the dorsal line of the fuselage and via struts originated from the lower section of the aircraft. The undercarriage is wheeled and retractable. The passenger cabin will seat thirty in relative comfort.

The currently-planned propulsion scheme relies on a battery array with reserve-hybrid turbogenerators driving four electric motors. Charging times for quick turnarounds will be in the vicinity of 30 minutes on fast charge based on presented marketing materials.

Range from the all-electric mode will allow the aircraft to reach out to 200 kilometers while the hybrid-electric operation will extend this to 400 kilometers. The aircraft is eventually projected to have an all-out range of 800 kilometers through a hybrid-electric 25pax function. Maximum altitude is estimated to be 20,000 feet. Performance will further be impacted, for the better, as battery technology improves to more efficient, lower-cost standards.

The ES-30 is marketed with a cost-effective, completely accessible low-noise and zero emissions footprint. Low noise will be a welcomed quality to both busy and rural airports.©MilitaryFactory.com
