The Open Fan engine architecture is being developed to deliver a significant step change in efficiency and durability for the next generation of single-aisle aircraft. Its distinctive design could shape the propulsion systems selected for future narrowbody fleets and influence aircraft development priorities.
Heart Aerospace has replaced its previously announced ES-30 with the 36-seat ES-36, a hybrid-electric regional aircraft. JSX has committed to up to 100 aircraft, with commercial service targeted for 2031, establishing an initial customer and a defined timeline for the program’s market entry.
Virgin Atlantic CEO Corneel Koster criticized growing mandates for sustainable aviation fuel, arguing that customers should not be asked to pay more while SAF supply remains constrained and the promised environmental benefits are not being delivered. His comments highlight the tension between policy targets, fuel availability and airline cost pressures.
Bye Aerospace has completed the first flight of its eFlyer 2 prototype, an all-electric aircraft designed for the flight-training market. The milestone advances the company’s effort to develop electric propulsion for general aviation and pilot training applications.

Heart Aerospace has unveiled the ES-36, its fourth design iteration, replacing the earlier independent hybrid-electric architecture with a simplified twin-electric-motor configuration and increased payload. JSX has committed to 50 firm aircraft with deposits and 50 options, while Heart targets commercial service entry in 2031.
The European Union is allocating $494 million in sustainable aviation fuel allowances to carriers for 2025. The funding provides direct support for airline SAF adoption while underscoring the growing role of policy mechanisms in meeting Europe’s aviation decarbonization objectives.

Electra used taxiways, heliports and a drag strip across Virginia to demonstrate short-haul, point-to-point operations for its EL2 fixed-wing aircraft. The tests at Roanoke–Blacksburg Regional Airport were intended to assess potential future airport procedures, while raising questions about passenger comfort aboard the planned nine-seat EL9.
