Australia’s Rex Airlines has partnered with startup Dovetail Electric Aviation to convert turbine-powered aircraft to electric propulsion, initially targeting regional and general aviation aircraft.

Range is the mantra of hybrid-electric propulsion developers, and Ampaire has demonstrated the potential of combining electric and thermal power to overcome the limitations of batteries in an aircraft powertrain.

Full-scale cabin mockups unveiled by Eve and Supernal display common themes but distinctly different approaches to the passenger experience.

First flown in 1982 and still in production almost 40 years later, the Cessna Caravan is playing a key role in the introduction of advanced air mobility and alternative propulsion.

As startups advance zero-emission hydrogen fuel-cell propulsion toward production by the mid-2020s for aircraft with up to 50 seats, a UK research program is indicating the technology’s potential to power regional airliners with 100 seats.

The U.S. Energy Department has awarded Raytheon two research and development projects to test hydrogen and ammonia as zero-carbon fuels for electricity generation.

The EngineUS 100 motor will form part of an integrated parallel-hybrid propulsion system.

First flight of a hydrogen fuel cell-powered electric engine could come within weeks.

Airbus UpNext plans to flight test a hydrogen-burning engine at altitude on a powered glider.

The engine-maker says it has performed the world’s first test in simulated altitude conditions of a megawatt-class and multi-kilovolt hybrid-electric propulsion system.

Study finds electric aircraft’s effect on decarbonizing aviation could be greater than their direct contribution to reducing emissions.

In 2011, a team led by L-3 Communications demonstrated electric taxiing at Frankfurt Airport with a Lufthansa Airbus A320.

The Raytheon companies are developing a hybrid-electric technology demonstrator program.

Eve has unveiled a mock-up of the proposed cabin and shared a revised external configuration.

German startup Nex Aero has taken the wraps off plans to develop a longer range electric vertical takeoff and landing air taxi powered by gaseous hydrogen and fuel cells.

Textron is tapping into the market for low-cost intelligence surveillance and reconnaissance aircraft through new subsidiary Pipistrel, the Slovenian general aviation pioneer.

The findings could affect the flight testing of new concepts in the UK.

Iris Automation and Sagetech Avionics have partnered to bring cooperative and noncooperative traffic detection and collision avoidance capabilities to drones operating beyond visual line of sight.

Overair is using prepreg carbon fiber from Toray Composite Materials to build the full-scale prototype of its Butterfly tilt-rotor electric vertical takeoff and landing air taxi.

The AeroDelft student team from Delft Technical University, the Netherlands, has flown a subscale prototype under its Project Phoenix to convert a light general aviation aircraft to liquid-hydrogen propulsion.

Vertical Aerospace has partnered with Taiwan’s E-One Moli Energy to supply lithium-ion battery cells for its VX4 electric vertical takeoff and landing air taxi.

The partners in a project to convert the Cessna Caravan to electric propulsion have formed a new company to develop and offer battery-electric and hydrogen-electric powertrain retrofits for a range of turboprop commuter aircraft.
