EAA AirVenture ’24 was filled with aircraft debuts, technology advancements, flying and commemorating milestones.

P&WC is working with Maeve on a propulsion system for the European startup's planned hybrid-electric regional turboprop for the 80-seat-class market.

Pratt says the engine developed for the company’s Hybrid-Electric Propulsion (HEP) flight demonstrator has run at full power for the first time.

Heat exchanger for hydrogen engines; conformal LH2 tank; fuel system for LH2; and fuel-cell powertrain tested.

Jekta has selected ZeroAvia to develop a hydrogen-electric, fuel-cell-powered version of its PHA-ZE 100 amphibian, originally designed to rely on batteries.

Collins Aerospace has passed the passed the preliminary design review for the EU's Clean Aviation HECATE project.

Eve Air Mobility, Embraer’s advanced air mobility spinoff, has rolled out the first of six Eve prototypes to support the eVTOL program through developmental flight testing.

Blades of the first ducted fan thruster in the hybrid propulsion system are “spinning as we speak,” GA-ASI President David Alexander said.

In a milestone for electric aircraft, Electric Power Systems (EPS) has submitted the first application for FAA approval of a lithium propulsion battery system.

New aircraft technologies are being overlooked in the 2050 carbon net-zero quest, startups and researchers say.

After the initial funding wave, investors grow leery of unfulfilled promises by startups.

Comparing hydrogen-electric propulsion startups Universal Hydrogen and ZeroAviation reveals companies with quite different business approaches.

American Airlines has signed a conditional purchase agreement with ZeroAvia for 100 hydrogen-electric engines to power regional jets.
