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.

The study finds that main contributors to almost all environmental impact categories are the airframe, battery and emissions in operations.

A specialist in experimental rotorcraft, Piasecki eyes the transition from R&D to production.

Company believes swappable battery design will make it easier to upgrade vehicle.

FBO Atlantic Aviation has signed agreements with Archer and Joby Aviation to install electric aircraft charging sites at a handful of its airport terminals.

ICAO’s third Conference on Aviation and Alternative Fuels reached an agreement to reduce CO2 emissions in international aviation by 5% by 2030.
