Demonstrators built under Clean Sky 2, the project’s predecessor, were exhibited at the annual forum as a source of motivation.

Rolls-Royce has begun bench tests of its first 320-kW electric motor demonstrator for potential regional aircraft applications.

Surf Air Mobility said it now expects to receive FAA certification for its electrified powertrains in 2027.

High-speed testbeds make progress; validating a digital twin; non-CO2 emissions road map; power-beamed UAV; SAF via bacteria.

While French innovators are making gradual progress in electric, hybrid-electric and hydrogen propulsion, they are looking for critical funding.

Certifying electric engines; Call for UK hydrogen funding; More eVTOLs for USAF; and the UK’s future flight road map.

Fuel systems for hydrogen; 3D printing on the Moon; LH2 tank breakthrough; the cost of avoiding contrails; and Velis Electro approved for training.

After 35 years, Heli-Expo is transforming into a new, broader event to be called Verticon.

Ultraquiet propulsion developer Whisper Aero is proposing a concept for a 100-seat battery-electric regional airliner.

Spanish aerostructures and engine components supplier Aciturri is to acquire a stake in Dovetail Electric Aviation.

Sikorsky has unveiled the configuration of the Hybrid-Electric Demonstrator (HEX), a fully autonomous prototype to be developed with GE Aerospace, at Heli-Expo.

As the Airbus CEO is adamant that hydrogen propulsion is feasible, the Climate Impulse project might do some groundwork for the technology.

Dovetail Electric Aviation has begun tests of an integrated hydrogen fuel-cell powerplant targeted at flight tests on a modified Beechcraft King Air.

The first flight of the ERA is scheduled for 2026 and entry into service for 2028.

Two-thirds of Europe’s Clean Aviation research projects are focused on more sustainable advanced propulsion technologies for service entry in the mid-2030s.

Beta’s Alia electric aircraft has participated in a U.S. Air National Guard exercise.

The GoAero organization has launched a competition to develop and test a vertical-takeoff-and-landing aircraft in simulated emergency response missions.

Daher says the hybrid-electric Ecopulse demonstrator has now logged 1.5 hr. of flight testing in full electric mode.

U.S.-European startup Cosmic Aerospace has raised $4.5 million in seed financing to progress development of a 24-passenger all-electric regional aircraft.

The aircraft propulsion system is powered by hydrogen fuel cells in combination with a booster battery pack that is used during peak power demands.
