Heart Aerospace has introduced the ES-36, a 36-seat regional airliner that utilizes a hybrid-electric powertrain. The company has already secured an agreement with JSX for an initial purchase of 50 of the new aircraft.
Why it matters
This aircraft is designed to facilitate regional travel between community airports with a smaller environmental footprint. The hybrid propulsion system and simplified two-propeller design aim to improve operational efficiency and lower maintenance costs.
The ES-36 features two 1.65 MW electric motors and a turbogenerator that supplements battery power. It is designed to carry a payload of 1,415 pounds while maintaining the same takeoff weight as the manufacturer's previous ES-30 model.
The players
Heart Aerospace
This California-based manufacturer specializes in the development of electric and hybrid-electric regional aircraft.
JSX
This company is a regional carrier that focuses on providing semi-private air travel services.
The details
The design reduces maintenance complexity by utilizing two propellers instead of four, relying on a gas turbine turbogenerator to extend the aircraft's range beyond its 125-mile electric limit. JSX holds options for an additional 50 aircraft, signaling significant regional interest in the hybrid technology.
Timeline
Heart Aerospace debuted the ES-30 model in 2022.
The X1 demonstrator aircraft flew in 2026.
The ES-36 airliner was unveiled on September 23, 2026.
The first flight of the ES-36 is expected in the second half of 2028.
Entry into service for the aircraft is planned for 2031.
Travel Outlook
The transition toward hybrid-electric regional flight represents a significant pivot from traditional fossil-fuel-dependent turboprops. This development follows the precedent set by the ES-30 model, signaling a broader industry shift toward decarbonizing short-haul community transit.
Travelers should anticipate that these regional hybrid aircraft will primarily service smaller community airports rather than major international hubs. As the 2031 service entry approaches, commuters in regional markets may gain access to more frequent, lower-emission flight options.
The takeaway
Hybrid-electric technology is rapidly maturing to address the maintenance and environmental challenges of regional aviation. Passengers can expect these planes to eventually bridge the gap between expensive private charters and traditional commercial air travel.
